The Impacts of Junk Food on Health

Energy-dense, nutrient-poor foods, otherwise known as junk foods, have never been more accessible and available. Young people are bombarded with unhealthy junk-food choices daily, and this can lead to life-long dietary habits that are difficult to undo. In this article, we explore the scientific evidence behind both the short-term and long-term impacts of junk food consumption on our health.

Introduction

The world is currently facing an obesity epidemic, which puts people at risk for chronic diseases like heart disease and diabetes. Junk food can contribute to obesity and yet it is becoming a part of our everyday lives because of our fast-paced lifestyles. Life can be jam-packed when you are juggling school, sport, and hanging with friends and family! Junk food companies make food convenient, tasty, and affordable, so it has largely replaced preparing and eating healthy homemade meals. Junk foods include foods like burgers, fried chicken, and pizza from fast-food restaurants, as well as packaged foods like chips, biscuits, and ice-cream, sugar-sweetened beverages like soda, fatty meats like bacon, sugary cereals, and frozen ready meals like lasagne. These are typically highly processed foods , meaning several steps were involved in making the food, with a focus on making them tasty and thus easy to overeat. Unfortunately, junk foods provide lots of calories and energy, but little of the vital nutrients our bodies need to grow and be healthy, like proteins, vitamins, minerals, and fiber. Australian teenagers aged 14–18 years get more than 40% of their daily energy from these types of foods, which is concerning [ 1 ]. Junk foods are also known as discretionary foods , which means they are “not needed to meet nutrient requirements and do not belong to the five food groups” [ 2 ]. According to the dietary guidelines of Australian and many other countries, these five food groups are grains and cereals, vegetables and legumes, fruits, dairy and dairy alternatives, and meat and meat alternatives.

Young people are often the targets of sneaky advertising tactics by junk food companies, which show our heroes and icons promoting junk foods. In Australia, cricket, one of our favorite sports, is sponsored by a big fast-food brand. Elite athletes like cricket players are not fuelling their bodies with fried chicken, burgers, and fries! A study showed that adolescents aged 12–17 years view over 14.4 million food advertisements in a single year on popular websites, with cakes, cookies, and ice cream being the most frequently advertised products [ 3 ]. Another study examining YouTube videos popular amongst children reported that 38% of all ads involved a food or beverage and 56% of those food ads were for junk foods [ 4 ].

What Happens to Our Bodies Shortly After We Eat Junk Foods?

Food is made up of three major nutrients: carbohydrates, proteins, and fats. There are also vitamins and minerals in food that support good health, growth, and development. Getting the proper nutrition is very important during our teenage years. However, when we eat junk foods, we are consuming high amounts of carbohydrates, proteins, and fats, which are quickly absorbed by the body.

Let us take the example of eating a hamburger. A burger typically contains carbohydrates from the bun, proteins and fats from the beef patty, and fats from the cheese and sauce. On average, a burger from a fast-food chain contains 36–40% of your daily energy needs and this does not account for any chips or drinks consumed with it ( Figure 1 ). This is a large amount of food for the body to digest—not good if you are about to hit the cricket pitch!

• Figure 1 - The nutritional composition of a popular burger from a famous fast-food restaurant, detailing the average quantity per serving and per 100 g.
• The carbohydrates of a burger are mainly from the bun, while the protein comes from the beef patty. Large amounts of fat come from the cheese and sauce. Based on the Australian dietary guidelines, just one burger can be 36% of the recommended daily energy intake for teenage boys aged 12–15 years and 40% of the recommendations for teenage girls 12–15 years.

A few hours to a few days after eating rich, heavy foods such as a burger, unpleasant symptoms like tiredness, poor sleep, and even hunger can result ( Figure 2 ). Rather than providing an energy boost, junk foods can lead to a lack of energy. For a short time, sugar (a type of carbohydrate) makes people feel energized, happy, and upbeat as it is used by the body for energy. However, refined sugar , which is the type of sugar commonly found in junk foods, leads to a quick drop in blood sugar levels because it is digested quickly by the body. This can lead tiredness and cravings [ 5 ].

• Figure 2 - The short- and long-term impacts of junk food consumption.
• In the short-term, junk foods can make you feel tired, bloated, and unable to concentrate. Long-term, junk foods can lead to tooth decay and poor bowel habits. Junk foods can also lead to obesity and associated diseases such as heart disease. When junk foods are regularly consumed over long periods of time, the damages and complications to health are increasingly costly.

Fiber is a good carbohydrate commonly found in vegetables, fruits, barley, legumes, nuts, and seeds—foods from the five food groups. Fiber not only keeps the digestive system healthy, but also slows the stomach’s emptying process, keeping us feeling full for longer. Junk foods tend to lack fiber, so when we eat them, we notice decreasing energy and increasing hunger sooner.

Foods such as walnuts, berries, tuna, and green veggies can boost concentration levels. This is particularly important for young minds who are doing lots of schoolwork. These foods are what most elite athletes are eating! On the other hand, eating junk foods can lead to poor concentration. Eating junk foods can lead to swelling in the part of the brain that has a major role in memory. A study performed in humans showed that eating an unhealthy breakfast high in fat and sugar for 4 days in a row caused disruptions to the learning and memory parts of the brain [ 6 ].

Long-Term Impacts of Junk Foods

If we eat mostly junk foods over many weeks, months, or years, there can be several long-term impacts on health ( Figure 2 ). For example, high saturated fat intake is strongly linked with high levels of bad cholesterol in the blood, which can be a sign of heart disease. Respected research studies found that young people who eat only small amounts of saturated fat have lower total cholesterol levels [ 7 ].

Frequent consumption of junk foods can also increase the risk of diseases such as hypertension and stroke. Hypertension is also known as high blood pressure and a stroke is damage to the brain from reduced blood supply, which prevents the brain from receiving the oxygen and nutrients it needs to survive. Hypertension and stroke can occur because of the high amounts of cholesterol and salt in junk foods.

Furthermore, junk foods can trigger the “happy hormone,” dopamine , to be released in the brain, making us feel good when we eat these foods. This can lead us to wanting more junk food to get that same happy feeling again [ 8 ]. Other long-term effects of eating too much junk food include tooth decay and constipation. Soft drinks, for instance, can cause tooth decay due to high amounts of sugar and acid that can wear down the protective tooth enamel. Junk foods are typically low in fiber too, which has negative consequences for gut health in the long term. Fiber forms the bulk of our poop and without it, it can be hard to poop!

Tips for Being Healthy

One way to figure out whether a food is a junk food is to think about how processed it is. When we think of foods in their whole and original forms, like a fresh tomato, a grain of rice, or milk squeezed from a cow, we can then start to imagine how many steps are involved to transform that whole food into something that is ready-to-eat, tasty, convenient, and has a long shelf life.

For teenagers 13–14 years old, the recommended daily energy intake is 8,200–9,900 kJ/day or 1,960 kcal-2,370 kcal/day for boys and 7,400–8,200 kJ/day or 1,770–1,960 kcal for girls, according to the Australian dietary guidelines. Of course, the more physically active you are, the higher your energy needs. Remember that junk foods are okay to eat occasionally, but they should not make up more than 10% of your daily energy intake. In a day, this may be a simple treat such as a small muffin or a few squares of chocolate. On a weekly basis, this might mean no more than two fast-food meals per week. The remaining 90% of food eaten should be from the five food groups.

In conclusion, we know that junk foods are tasty, affordable, and convenient. This makes it hard to limit the amount of junk food we eat. However, if junk foods become a staple of our diets, there can be negative impacts on our health. We should aim for high-fiber foods such as whole grains, vegetables, and fruits; meals that have moderate amounts of sugar and salt; and calcium-rich and iron-rich foods. Healthy foods help to build strong bodies and brains. Limiting junk food intake can happen on an individual level, based on our food choices, or through government policies and health-promotion strategies. We need governments to stop junk food companies from advertising to young people, and we need their help to replace junk food restaurants with more healthy options. Researchers can focus on education and health promotion around healthy food options and can work with young people to develop solutions. If we all work together, we can help young people across the world to make food choices that will improve their short and long-term health.

500 Word Essay On Harmful Effects Of Junk Food

Junk food is extremely harmful because it is slowly destroying the health of the current generation. Even the word "junk" itself alludes to how bad it is for our bodies. Most importantly, people regularly consume it because of how good it tastes. However, they are unaware of the negative consequences it might have. You can't even begin to comprehend how serious the issue is. Several studies have demonstrated the high calorie, fat, and sugar content of junk food. On the contrary, they are incredibly low in good nutrition and roughage.

Consequences Of Junk Food

The quickest way to put on unwanted weight is by eating junk food. You gain weight quickly because of how much sugar and fat are in the food. However, this weight is unhealthy. It contains more fat and cholesterol, both of which are bad for your health. One of the main causes of the rise in obesity in modern society is junk food.

The only appealing aspects of the food are how it looks and tastes. These foods do not provide your body with the necessary amount of nutrients. For instance, foods like noodles, burgers, and candies all have high fat and sugar content , but they lack good nutrients. Therefore, this could result in a number of diseases like diabetes and high blood pressure.

Above all, if you don't get enough of the necessary vitamins, minerals, and nutrients, you could develop a variety of nutritional deficiencies. Consuming unhealthy fats and cholesterol makes you more vulnerable to cardiovascular diseases as well.

Effects Of Junk Food

When I got accepted to my college, which was based in Punjab, I made a lot of friends there who were from other states. I met a girl from Kolkata who was staying in the hostel and was extremely underweight when she first arrived. She started eating junk food every day because the food provided in the hostel did not suit her taste buds. She used to consume fast food two or more times per day. After two to three months, she significantly increased her weight, and she also developed health issues like high blood pressure and recurrent stomach aches.

The doctor claimed that because of her frequent consumption of junk food, she has high blood pressure and an unreliable stomach. Her food was therefore not being digested. After watching her, I made the decision to limit my consumption of junk food to no more than two to three times per month.

Preventing Junk Food

The main issue with junk food is that, until recently, people were unaware of its negative effects. So, here are some strategies you can use to try to stay away from junk food.

Consume regular meals to prevent becoming overly hungry.

Before consuming any sugar-sweetened beverages, drink some water.

Consume calorie- and nutrient-conscious snacks.

Know the sources that trigger you to have junk food

In other words, it's not a good idea to completely abstain from eating junk food. However, you should cut back on your junk food intake. They shouldn't be consumed frequently.

Junk food-induced obesity- a growing threat to youngsters during the pandemic

Introduction.

Obesity has been declared an epidemic that does not discriminate based on age, gender, or ethnicity and thus needs urgent containment and management. Since the third wave of COVID-19 is expected to affect children the most, these children and adolescents should be more cautious while having junk foods, during covid situations due to the compromise of Immunity in the individuals and further exacerbating the organ damage.

Methodology

A PAN India survey organized by the Centre for Science and Environment (CSE) among 13,274 children between the ages 9–14 years reported that 93% of the children ate packed food and 68% consumed packaged sweetened beverages more than once a week, and 53% ate these products at least once in a day. Almost 25% of the School going children take ultra-processed food with high levels of sugar, salt, fat, such as pizza and burgers, from fast food outlets more than once a week. Children and adolescents who consume more junk food or addicted to such consumption might be even more vulnerable during the third wave, which will significantly affect the younger category.

There is an urgent need to spread awareness among children and young adults about these adverse effects of junk food. There is no better time than now to build a supportive environment nurturing children and young adults in society and promising good health.

1. Introduction

Obesity has been declared as epidemic that does not discriminate based on age, gender, or ethnicity and thus needs urgent containment and management. Cardiovascular complications are a global threat with the rapid increase in the prevalence of obesity; by 2025, it is expected to reachupto 18% in men and 21% in women by forbidding heavy burden upon individuals, societies, and health care systems. Heart attack survivors with excess fat around their waist are at increased risk of another cardiac arrest, according to the journal of the European Society of Cardiology (Mohammadi H et al., 2020).

In the modern era, obesity is linked with various factors enhancing the production of cortisol, such as Food consumption with a high glycaemic index, chronic stress, and change in sleep patterns ( Knutson et al., 2010 ; Cohen and Janicki-Deverts, 2012 ). The burden of non-communicable disease has become a major threat globally, attributing to physical inactivity, unhealthy dietary habits, unhealthy lifestyle, and smoking. It is also observed that food with high levels of fat content is preferred to non-fat food by people ( Visschers and Siegrist, 2010 ). Based on the reports, more than one-third of the adults eat junk food several times a week ( Bauer et al., 2009 ). Studies have proven that Junk food tends to cause obesity (central adiposity), a primary concern of heart diseases and other non-communicable diseases ( Rouhani et al., 2012 ; Musaiger, 2014 ). Poor nutrition could result in reduced Immunity, susceptibility to several oral and systemic diseases, impaired physical and mental growth, and reduced efficiency (Bhattacharya, P. T et al., 2016).

Greater than 60% of the overweight child population seem to have at least one added risk factor of cardiovascular disease (Raised blood pressure, hyperlipidemia, hyperinsulinemia), and more than 20% of the obese children have two or more risk factors. The United States National Centre for Health Statistics suggests that nearly 15% of adolescents are overweight or obese, and treatment is harder in adults than children ( International Life Sciences Institutes, 2000 ). It is observed that an adolescent is often negligible to his health due to improper awareness and a busy work schedule. With more than 14.4 million obese children, India has the second-largest obese child population in the world. By 2025 it is anticipated to reach a stunning 17 million.

Since the third wave of COVID-19 is expected to affect children the mostly, it is, therefore, advisable for these children and adolescents who eat Junk foods to be more cautious during Covid situations due to the compromise of Immunity in the individuals and further exacerbating the organ damage.

2. Junk foods overview

Children find themselves amidst a way of living that has been metamorphized to suit the new jet-setting age and the food is no exception to this. Over the last two decades, the variability of healthy eating advice has become a cliché, leading to an alarming increase in the trend of consumption of fast food and sweetened beverages in Indian children. On average, the fast-food industry is growing 40% per year ( Joseph et al., 2015 ). A PAN India survey organized by the Centre for Science and Environment (CSE) among 13,274 children between the ages 9–14 years reported that 93% of the children ate packed food and 68% consumed packaged sweetened beverages more than once a week, and 53% ate these products at least once in a day. Almost 25% of the School going children take ultra-processed food with high levels of sugar, salt, fat, such as pizza and burgers, from fast food outlets more than once a week ( Bhushan et al., 2017 ). The most commonly consumed junk food items are bakery products, beverages, burgers, caffeinated drinks, chips, chocolates, noodles, pizza, soft drinks, and sugar-sweetened drinks. Harmful effects of Junk foods include Overweight/Obesity, Cardiometabolic risk, High blood pressure, Behavioural symptoms and Dental caries.

3. Highly consumed junk foods

Habitual physically inactive lifestyle, advertisements, media, and consumption of junk food have contributed significantly towards causing obesity in children and adolescents. Various list of Junk foods and their associated components showing the impact on health is mentioned in Table 1 .

List of Junk foods and its associated components showing impact on health.

4. Impact of junk foods on body weight

The rates of overweight and obesity have increased tremendously over the past few decades as a health epidemic in most parts of the world ( Mancino and Kinsey, 2008 ; LaCaille et al., 2011 ; Allom and Mullan, 2014 ). High consumption of Junk Foods contributes to the overweight among School-aged children in India from 9.7% to 13.9% over a decade ( Ranjani et al., 2016 ). The potential adverse effects on weight status in younger population include Physical inactivity and unhealthy dietary habits and, consequently, the future health of adults ( Hutchesson et al., 2015 ; Allom and Mullan, 2014 ). High intake of fried foods and artificially sweetened drinks are found to be directly linked with high body mass index and obesity in children. Additionally, diets with elevated amounts of Junk food have very little quantity of nutrients ( Goel et al., 2013 ; Harnack et al., 1999 ).

5. Preclinical evidences of junk food and its effect

The preclinical data is essential in collecting the safety of drug, iterative testing, and the feasibility of experiment which is given in Table 2 . In a study conducted in 1991, brown and white adipose tissue in high fat and junk diet and chow-fed rats with dorsomedial hypothalamic lesion rats ( Bernardis and Bellinger, 1991 ). The animals were grouped as high fat and control rats as group 1 and 3, whereas chow diet and control were grouped as group 2 and 4. He found that obesity is not only linked to calories but rather the sort of calories consumed, brown adipose tissue weight, lipid content, protein and turnover of NE are indicators of metabolic activity and thermogenesis that are unreliable. Oginsky et al. (2016) proposed that intake of junk food shows a rapid and long-lasting increase in NAc CP-AMPA receptors for food addiction. In general, mesolimbic circuits responsiveness is intensified in rats that are vulnerable to diet-induced obesity.

Pre-clinical and clinical evidence of Junk food and its effect.

Additionally, junk food was found to increase NAc CP-AMPAR function in obesity-susceptible rats. AMPA upregulation occurred more promptly in obesity-susceptible rats and preceded the development of obesity. Cocaine-induced locomotion was seen, and post-junk-food deprivation, cocaine-induced movement was enhanced in Junk-Food-Gainers than in the Non-Gainers, i.e., Junk-Food gainers were more sensitized when compared to non-gainers. He concluded that it will be significant to determine the extent to which these food-induced changes occurring in the striatal function could be part of normal, adaptive processes vs maladaptive, ‘addictive-like behaviors. A study conducted on 2010 by StephanieA stated in a study that a junk food diet in pregnancy and lactation promotes Non-alcoholic fatty liver in the rat offspring. It was observed that those junk food-fed mothers moved to an exclusive chow diet from weaning which resulted in the increase of triglyceride compared to the CCC group at the end of adolescence. The histological analysis did not disclose any signs of fibrosis or inflammation confirmed by unaffected TNF-alpha, IL-6, Collagen, and keratin expressions, suggesting that although they showed NAFLD signs, they did not suffer from NASH. He also mentioned that exacerbated steatosis in those offsprings did not coexist with an increase in carnitine palmitoyltransferase I (Cpt1a) mRNA expression, which might be an indicator of mitochondrial Beta-oxidation saturation leading to further lipid accumulation in the liver. In 2008 an observation was made on off springs of Junk food-fed mothers in pregnancy and lactation exhibited aggravated adiposity, which is highly found in females ( Bayol et al., 2008 ).

The perirenal fat pad mass linked to body weight was greater in the offsprings fed with junk food throughout the study than those fed with junk food diet postweaning. The increase in adiposity is associated with the weight gain previously reported in the same animals. The study on gene expression and changes in adipose tissue cellularity showed that an increase in IGF-1 transcription indicated higher proliferation of pre-adipocyte in females fed with junk food diet after weaning compared to males. Gugusheff et al., 2013 studied extensively the effects of prenatal junk food exposure on food preferences of offspring and how fat deposition can be alleviated by enhanced nutrition during lactation ( Gugusheff et al., 2013 ). He found that habitual cafeteria diet during the suckling period, independent of dietary exposure before birth, led to the development of diet-induced obesity in females and an increase in preference for appetizing foods in male offspring in young adulthood. The animals were given free access to the cafeteria diet. Female offspring suckled by JF dams had increased fat mass compared to those offspring suckled by control dams independent of the diet consumed by the mother during pregnancy. It is to be noted that it took place in the absence of high food consumption, suggesting that these animals had an enhanced propensity to accumulate fat in the body.

6. Clinical evidence of junk food and its effect

The clinical data collection is very much helped by the quality of information generated, which plays a significant part in yielding the study results whose clinical data are given in Table 2 .

Zahedi et al. (2014) studied the relationship between junk food consumption and mental health in a Sample of Iranian Children and Adolescents ( Zahedi et al., 2014 ). In this study, a notable link between junk food consumption and mental health problems in children and adolescents was observed. Students that consumed junk food daily were more likely to be subjected to mental health problems. The Western Australian Pregnancy Cohort Study proposed that the Western dietary pattern of increased consumption of takeaway foods, red meat, and confectionary was significantly associated with poor behavioral outcomes in adolescents. Similarly, two cohort studies in adolescents instigated that increased intake of unhealthy foods like sweets, savory snacks, sweetened soft drinks, chocolate, and fast foods was associated with a high risk of behavioral problems and mental distress such as anxiety worthlessness, and dizziness.

Azemati et al., 2020 studied an association between consumption of junk food and cardiometabolic risk factors in Iranian children and adolescent population ( Azemati et al., 2020 ). A population-based study in Korea showed that fast food consumption was linked to metabolic syndrome in adolescents. The study demonstrated that sweet dietary habits were positively related to metabolic syndrome, and those under junk food consumption were more likely to be overweight. Junk foods are found to be associated with obesity due to their high energy content and the amount of fat present or free sugar, chemical additives, and sodium with the presence of a low amount of micronutrients and fiber. Among junk foods, intake of sweetened beverages is in close relationship with weight fluctuations as it can increase food intake through decreasing satiety mechanisms. In Conclusion, junk food intake among Iranian children and adolescents had undesirable effects on cardiometabolic risk factors. Thus, enhancing knowledge of junk foods among adolescents is one of the possible ways to help them to make healthy food choices and get rid of overweight and obesity.

Zhu et al. (2019) investigated on the current situation and influencing factors on consuming junk foods among children and adolescents in Beijing city ( Zhu et al., 2019 ). He used a questionnaire survey method to survey the junk food habits and their effects. One month before the survey, all individuals have an intake of one type or the other junk foods. Mostly they didn't have an understanding of nutrition, and mostly they have misunderstandings about nutritional value and effect on the human body. Their behavior is affected mainly by personal factors like physiological, psychological, social, family factors, and the food itself. In Conclusion, children and adolescents in Haidian District ate different types of junk food, and the safety, nutritional issues of junk food should be paid great attention to prevent and control the risk factors of children and adolescents eating junk food. Payab et al. (2015) studied the relationship between junk food consumption with high blood pressure and obesity in Iranian children and adolescents ( Payab et al., 2015 ).

This study showed significant link between sweet consumption and both general and abdominal obesity. Nonetheless, there was no meaningful relationship between sweets consumption and high blood pressure. Several studies also showed that in general, central obesity is inversely associated with healthy dietary habits, while the Western dietary habits (refined grains, Red meat, sweets, desserts, pizza, French fries, and soft drinks) were directly linked to obesity.

7. Junk food and compromised immune system

• i) Effect of Junk foods on the signaling pathway

The intake of appetizing food is primarily under the control of the limbic system and stimulates endogenous opioids release, which binds to the opioid receptors present in the ventral tegmental area (VTA). VTA activates dopaminergic neurons in the brain, and in the nucleus accumbent, the site of dopamine release to potentiate dopamine signaling pathway ( Bergevin et al., 2002 ; Fields and Margolis, 2015 ; Berridge, 1996 ). The stimulation of the dopamine signaling pathway by opioid interactions is thought to be involved in the mediation of the short-term pleasurable sensation linked with the consumption of appetizing food ( Bodnar et al., 2005 ; Bodnar, 2015 ). It is observed that a reduction in MuR expression in the offspring of dams maintained on a junk food diet during pregnancy and lactation is present in the VTA at the weaning stage, i.e., 3 weeks after birth ( Gugusheff et al., 2013 ). Nonetheless, MuR expression in the NAcis found in elevated levels during the first postnatal week and declining to adult levels over the next two weeks ( Tong et al., 2000 ).

• ii) Effect of Junk foods on Immunity

Micronutrients like trace elements, antioxidants, and vitamins play a significant role in the regenerative process, coping with existing oxidative stress in the body tissues and providing Immunity against pathogens ( Chapple et al., 2007 ; Enwonwu et al., 2002 ). Obesity in the early years of life alters the immune system by inducing changes in cytokines concentrations and proteins and the number and function of the immune cells, ultimately leading to a pro-inflammatory condition, leading to the onset or exacerbation of numerous diseases like asthma, atopic dermatitis, allergy and sleep apnea ( Kelishadi et al., 2017 ). Various per- and polyfluorinated substances (PFAS)might affect growth, infantile behavior, learning, and older children. It also lowers the chance of pregnancy, interferes with the defense of natural hormones, increases the cholesterol levels, reduces vaccine-induced immune protection in children, and increase the risk of cancer ( Velez et al., 2015 ; Grandjean et al., 2017 ; Bach et al., 2015 ). Various reports from the conducted human studies conclude that some PFAS can take as long as 8–9 years to get cleared from the body ( Bartell et al., 2010 ). It can also cross the placental barrier and be secreted through breastmilk ( Mondal et al., 2013 ; Kingsley et al., 2018 ). It was observed that the immune response was impaired in children, especially cellular to influenza virus, and also inadequate vaccine responses were seen when they were obese ( Green and Beck, 2017 ). Thus, the importance of nutrition must be considered when it comes to Immunity. Similarly, there is enhanced knowledge about food, nutritional habits, and other lifestyle aspects, which are essential in aiding the proper functioning of the immune system ( Gombart et al., 2020 ).

In concern with obesity, there is a negative relationship between BMI and the intake of trace elements identified in obese people ( Farhat et al., 2019 ). Therefore, obesity has a strong correlation with an increased risk of infectious diseases accompanied by severe complications, elevated critical illnesses, and prolonged hospitalization ( Ritter et al., 2020 ). Systemic inflammatory reactions occur in covid 19 due to cytokine storms which leads to the imbalance of the immune system observed in obesity, and it contributes to a worse clinical outcome. Adipocytokines, mainly leptin, play an integral role in Immunity, as they influence the number and the function of immune cells through direct effects on cell metabolism ( Kim and Nam, 2020 ).

8. Influence of junk food during COVID-19 pandemic

COVID-19 lockdown had drastically altered the regular food pattern. When compared before pandemic, it shows both negative and beneficial impact on dietary practice associated with poor lifestyle management such as lack of physical activity and obesity. Nonetheless, poor eating habits were noticed such as changes in meal frequency and increased snacking with comfort foods (food bringing emotional comfort). It shows that alteration in dietary habits during the pandemic are at higher risk of further complications ( Bohlouli et al., 2021 ).

Since junk food tends to impact the immune system, it poses a greater risk during the pandemic. Children and adolescents who consume more junk food or are addicted to such consumption might be even more vulnerable during the third wave, which will especially affect the younger category (Janssen et al., 2021; Preethi et al., 2021 ).

9. Conclusion

Overweight and obesity are predominantly associated with numerous cardiac complications and are mostly mediated through the risk of metabolic syndrome. Obesity, like other malnutritional states, is known to impair immune function by altering leucocyte count as well as cell-mediated responses and causes organ damage. Not only is it causing physiological repressions, but it has significant psychological manifestations-that can damage a child's intellect and personality. Covibesity associated individuals are more prone to alteration of the immune system, and thus those people having junk food habits should be more cautious in this pandemic by maintaining health hygiene and getting vaccinated. It is to be noted that junk foods and packaging materials have drastic outcomes on health by impairing the immune system.

Thus, a combination of junk food, physical inactivity, and constant psychological stressors on children and adolescents during the pandemic makes them more vulnerable to increased weight along with decreased Immunity and thus an increased chance of infectivity during the third wave of COVID-19. There is an urgent need to spread awareness among children and young adults about these adverse effects of junk food, and they are not a good substitute for good healthy nourishment. There is no better time than now to build a supportive environment nurturing children and young adults in society and promising good health.

Essay on Junk Food in 150 Words

Junk food has become a prevalent component of the modern diet. It is not only attracting the young generation but is also getting induced in their daily diet. Habitual consumption of junk food causes serious health issues because it is high in calorie content. Processed food with high content of saturated and trans fats, or high sugar content comes under this category.

Street food places and the majority of food chains and restaurants are serving food in high quantities, thereby reducing the consumption of healthier options. People are now prioritizing taste and neglecting the culinary diversity of traditional food.

Another aspect of the over-consumption of junk food is ordering food on a daily basis due to a busy schedule. Besides that, munching on snacks to satisfy hunger is another bad habit that leads to health issues. Such food products lack nutritional components such as dietary fibres, protein, vitamins, iron, etc. 

To conclude, health is an important part of life so, it is important to take care of healthy food habits and avoid the excess consumption of unhealthy or junk food.

Impact of Consuming Junk Food

Food high in salt, sugar, and unhealthy fats contributes to weight gain. It will ultimately cause obesity. Obesity is the key source of other diseases that are difficult to cure. Some of the chronic diseases that occur due to the consumption of junk food are high risk of heart failure, GIT disorders, hypertension, diabetes, etc. So, it is crucial to eliminate or reduce the consumption of unhealthy food and replace it with nutritional food. 

Affordability

Another factor that contributes a lot in favour of a high intake of junk food is its affordability. Junk food is more accessible as it is available on the streets at a cheaper price. The price factor affects people who cannot afford healthier options. Thus, people tend to consume junk food that is comparatively more affordable and accessible.

Taste over Nutritional Value

Nowadays, people are more inclined towards enjoying the taste of food. It’s obvious that crispy and spicy food will attract you more as compared to salads and pulses i.e. much healthier options with high nutritional values. Consuming junk food on a regular basis has become common for many, and this has led to homogeneity in their diets. So, it’s important to choose the healthy option over a tastier option to minimize the negative health impact due to junk food.

In conclusion, having junk food occasionally is acceptable when you visit any party or celebrate any occasion. However, its regular consumption will disturb your dietary habits and also hamper your health for the long term.

Take it from the rats: A junk food diet can cause long-term damage to adolescent brains

Rats fed a diet full of fat and sugar in adolescence suffered memory impairment, USC researchers found. The study reinforces the important link between the gut and the brain.

A new USC-led study on rats that feasted on a high-fat, sugary diet raises the possibility that a junk food-filled diet in teens may disrupt their brains’ memory ability for a long time.

“What we see not just in this paper, but in some of our other recent work, is that if these rats grew up on this junk food diet, then they have these memory impairments that don’t go away,” said Scott Kanoski, a professor of biological sciences at the USC Dornsife College of Letters, Arts and Sciences. “If you just simply put them on a healthy diet, these effects unfortunately last well into adulthood.”

The study appears in the May issue of the journal Brain, Behavior, and Immunity .

In developing the study, Kanoski and lead author and postdoctoral research fellow Anna Hayes considered that prior research has shown a link between poor diet and Alzheimer’s disease. People who suffer from Alzheimer’s disease tend to have lower levels of a neurotransmitter called acetylcholine in the brain that is essential for memory and functions such as learning, attention, arousal and involuntary muscle movement.

The team wondered what this could mean for younger people who may be on a similar fat-filled, sugary Western diet, particularly during adolescence when their brain is undergoing significant development. By tracking the impact of the diet on the rats’ levels of acetylcholine and running the rats through some memory testing, they could learn more about the important relationship between diet and memory.

The researchers tracked the acetylcholine levels of a group of rats on a fatty, sugary diet and in a control group of rats by analyzing their brain responses to certain tasks designed to test their memory. The team examined the rats’ brains post-mortem for signs of disrupted acetylcholine levels.

The memory test involved letting the rats explore new objects in different locations. Days later, the researchers reintroduced the rats to the scene that was nearly identical except for the addition of one new object. Rats on the junk food diet showed signs they could not remember which object they had previously seen, and where, while those in the control group showed familiarity.

“Acetylcholine signaling is a mechanism to help them encode and remember those events, analogous to ‘episodic memory’ in humans that allows us to remember events from our past,” lead author Hayes explained. “That signal appears to not be happening in the animals that grew up eating the fatty, sugary diet.”

Kanoski emphasized that adolescence is a very sensitive period for the brain when important changes are occurring in development. “I don’t know how to say this without sounding like Cassandra and doom and gloom,” he said, “but unfortunately, some things that may be more easily reversible during adulthood are less reversible when they are occurring during childhood.”

There is at least some hope for intervention. Kanoski said that in another round of the study, the research team examined whether the memory damage in rats raised on the junk food diet could be reversed with medication that induces the release of acetylcholine. They used two drugs, PNU-282987 and carbachol, and found that with those treatments given directly to the hippocampus, a brain region that controls memory and is disrupted in Alzheimer’s disease, the rats’ memory ability was restored.

But without that special medical intervention, Kanoski said more research is needed to know how memory problems from a junk food diet during adolescence can be reversed.

In addition to Kanoski and Hayes, the team included other USC Dornsife researchers Logan Tierno Lauer, Alicia E. Kao, Molly E. Klug, Linda Tsan, Jessica J. Rea, Keshav S. Subramanian, Cindy Gu, Arun Ahuja, Kristen N. Donohue and Léa Décarie-Spain; Natalie Tanios of Keck School of Medicine of USC; as well as Anthony A. Fodor and Shan Sun of the University of North Carolina at Charlotte.

Kirschstein National Research Service Award from the National Institute on Aging F32AG077932 (AMRH), National Science Foundation Graduate Research Fellowships (separate awards to LT and KSS), Quebec Research Funds postdoctoral fellowship 315201 (LDS) and the Alzheimer’s Association Research Fellowship to Promote Diversity AARFD-22-972811 (LDS).

Long Essay on Junk Food 

This 500 words junk food essay has been provided as a reference for the students to jot down their own essay for exams. This has been written addressing the students of all age groups in a simple language. 

With the growing chains of fast-food restaurants and street foods, the young generation today has become more addicted to eating outside and are dependent on these junk foods. This has become a new trend in modern culture. Also, the marketing of various food brands such as KFC, Pizza Hut, Domino’s and McDonald’s have attracted more youngsters to go and consume such food items. Although these items taste good but are not at all considered healthy for our bodies. With their higher level of proteins, sugar and saturated fats, they tend to increase the cholesterol level in our body. They do not contribute to providing nutritional values required for the immune system and lack essential vitamins and minerals. 

Due to the busy day-to-day life, we often prefer ordering food from outside or munching on some snacks to satisfy our hunger. As a result, this has increased our addiction to eating junk every day. We often enjoy eating food that satisfies our taste buds and is less time-consuming. Since these junk foods are easily found nowadays with just a click on our phone, we tend to eat more of them. But we should keep in mind that these create a harmful impact on our body later and give rise to several health problems.

As per reports, the increase in the number of obesity cases has resulted due to the regular consumption of junk food items. Some of the severe health issues include cardiovascular diseases, a higher risk of obesity, PCOD/PCOS in females and several other chronic diseases which have a greater impact on our body and mental health.

Some of the commonly eaten junk foods include pizzas, burgers, deep-fries, food items made of processed cheese and high protein meat. Even some of the breakfast items and cereals tend to contain high amounts of sugar content. 

Since the risk of obesity and heart disease has become a major concern today, we should avoid the consumption of junk foods and sugary items. Replacing highly processed food items with a bowl of green salads and fruits can reduce the risk of high cholesterol in our bodies. Although we can consume junk food on some occasions, it must be followed by some physical activity to burn the calories consumed. 

To conclude, the health of an individual is an important part of their life and must be taken care of. It is, therefore, essential to make a habit of healthy eating instead of relying on these highly processed junk foods. This junk food essay in English is thus provided as a reference for the students to give them an idea about the harmful effects of junk foods.

FAQs on Junk Food Essay

1. Is Consumption of Junk Food in a Smaller Amount Harmful?

No, consumption of a very small amount of junk food on rare occasions doesn’t cause any harm. But after consumption, one must continue eating healthy food and perform some sort of physical exercise to burn the amount of high calorie that is being consumed.  One must incorporate a healthy lifestyle. In addition to eating healthy and nutritious food, one must avoid a sedentary lifestyle and stay physically active. With such a healthy lifestyle, eating small amounts of junk food can be enjoyable and harmless.

2. Why are Breakfast Cereals Considered Under Junk Foods?

Most of the cereals that we consume for breakfast have high sugar content in them which is not good for our health. Also, most of them are produced from refined wheat and refined sugars which add up the cholesterol and diabetes level in our body. Thus, they are regarded as junk foods. Also, they are more dangerous because people usually eat them thinking that they are healthier alternatives to other breakfast items and thus end up eating them more. 

3. How can one make better food choices?

There are several things that we can do to adopt a healthy overall lifestyle and also make better food choices. Here are a few of them:

Students of today live very hectic and stressful lives. This is true in particular for students who are driven and aim to have a competitive edge. With the extensive syllabus and tight schedules, care is rarely taken to eat healthily. Students, therefore, end up going on long hours without eating anything and then end up munching on unhealthy junk food as a quick reprieve. Social media and exposure to various global food chains is another reason why students end up eating more junk food than others.

5. What are some components of writing a good essay?
