Impacts of Junk Food, Obesity is a disease in which having too much body fat raises the chance of developing health issues. epidemic, which increases the likelihood of developing chronic illnesses including diabetes and heart disease. Despite the fact that junk food can contribute to obesity, our fast-paced lifestyles have made it a part of our daily lives. When you balance school, sports, and spending time with friends and family, life can get hectic. Junk food businesses produce food that is good, convenient, and inexpensive, so it has largely replaced making and eating wholesome homemade meals.
Fast food items like burgers, fried chicken, and pizza are examples of junk food, as are packaged items like chips, ice cream, and biscuits, as well as sugar-sweetened beverages like soda, fatty meats like bacon, sugary cereals, and frozen ready meals like lasagne. Usually, these are heavily processed foods. A raw agricultural product that has been washed, ground, cleaned, and/or cooked further, indicating that the food was prepared in numerous steps with the goal of making it palatable and easy to consume too much of. Unfortunately, junk food is high in calories and energy but low in the essential nutrients—like proteins, vitamins, minerals, and fiber—that our bodies need to develop and stay healthy.
Junk food can temporarily make you feel drained, bloated, and unable to focus & consumption over time can cause tooth decay and constipation. Junk food consumption can also result in obesity and its related illnesses, including heart disease.
These sorts of meals account for more than 40% of daily energy for Australian youths between the ages of 14 and 18. Junk food is another term for discretionary food. According to the Australian Dietary Guidelines, there are some foods and beverages that are “not essential to meet nutrient requirements and do not belong to the five food groups,” but they may offer diversity to a person’s diet. These five food groups are grains and cereals, vegetables and legumes, fruits, dairy and dairy substitutes, and meat and meat substitutes, according to the dietary recommendations of Australia and many other nations.
Junk food firms frequently use cunning advertising strategies to target young people, showing our heroes and symbols endorsing unhealthy meals. In Australia, a significant fast-food company sponsors cricket, one of our favorite sports. The bodies of professional athletes, such as cricket players, are not fueled by fried chicken, hamburgers, and fries! A study found that commercials for cakes, cookies, and ice cream were the most often seen foods among adolescents aged 12 to 17 who viewed over 14.4 million food advertisements in a single year on well-known websites. Another study that looked at kid-friendly YouTube videos found that 38% of all advertisements contained food or drink. A and 56% of those food advertisements were for junk food.
Impacts of Junk Food, Three main nutrients—carbohydrates, proteins, and fats—make up food. Additionally, food contains vitamins and minerals that promote sound health, development, and growth. During our teen years, getting the right nutrition is crucial. But when we eat junk food, we consume a lot of carbohydrates, proteins, and fats that the body absorbs very quickly.
Take eating a hamburger as an example. The bun provides carbohydrates, the beef patty provides proteins and fats, and the cheese and sauce also provide fats. Without taking into account any accompanying chips or beverages, a fast-food burger typically provides between 36% and 40% of your daily energy requirements (Figure 1). This is a lot of food to digest, which is bad if you’re going to hit the cricket field!
Figure 1 shows the nutritional breakdown of a well-known fast-food burger. including the typical amount per serving and per 100 g.
Burgers’ main source of carbs is bread, while their main source of protein is beef patties. The cheese and sauce include a significant amount of fat. According to Australian dietary standards, a single hamburger can provide 36% of the daily energy requirements for adolescent boys and 40% for teenage girls between the ages of 12 and 15.
Impacts of Junk Food, Unpleasant symptoms like fatigue, restless sleep, and even hunger might appear anywhere from a few hours to a few days after consuming rich, heavy foods like a burger (Figure 2). Junk food can result in a lack of energy rather than a boost. People who consume sugar, a form of carbohydrate, feel energized, joyful, and cheery for a brief while as their bodies utilize it as fuel. Nevertheless, refined sugar is the sort of sugar that is typically found in junk food. Sugar that has been processed from raw sources like sugar cane, sugar beets, or corn, causes a rapid drop in blood sugar levels. because it is metabolized so quickly by the body. This may result in fatigue and cravings.
The long- and short-term effects of eating junk food are shown in Figure 2.
Junk food might temporarily make you feel drained, bloated, and unable to focus. This junk food consumption over time can cause tooth damage and constipation. Junk food consumption can also result in obesity and its related illnesses, including heart disease. When junk food is consistently consumed over an extended period of time, the costs associated with health difficulties and damage rise.
Vegetables, fruits, grains, legumes, nuts, and seeds—foods from the five dietary groups—all include fiber, a healthy carbohydrate. Fiber helps to maintain a healthy digestive system and prolongs feelings of fullness by delaying the emptying of the stomach. Because junk food frequently lacks fiber, eating it causes our energy to decline and our hunger to rise more quickly.
Walnuts, berries, tuna, and green vegetables are some foods that might improve concentration. For young minds handling a lot of schoolwork, this is especially crucial. Most professional athletes eat these things! On the other side, consuming unhealthy foods may make it difficult to concentrate. Eating junk food might cause enlargement in the area of the brain responsible for memory. According to a human study, the learning and memory regions of the brain became disrupted after consuming an unhealthy breakfast high in fat and sugar for four days straight.
There may be a number of long-term effects on health if we consistently consume junk food over a period of weeks, months, or years (Figure 2). High-saturated fat, for instance, is a type of fat that is frequently consumed in meats like beef, chicken, and pork. And which usually encourages the body to produce “bad” cholesterol. Consumption is closely related to elevated blood levels of bad cholesterol, which can be an indication of heart disease. Young adults who consume relatively modest amounts of saturated fat have lower overall cholesterol levels, according to reputable studies.
Impacts of Junk Food, Regular junk food eating can also increase the chance of developing illnesses including hypertension and stroke. High blood pressure is another name for hypertension, and a stroke is brain damage brought on by decreased blood flow. Which deprives the brain of the oxygen and nutrition it requires to thrive. The excessive salt and cholesterol content in fast food can lead to hypertension and stroke.
Additionally, the Impacts of Junk Food consuming junk food can cause the production of the “happy hormone,” dopamine, which makes us feel good. Dopamine is a hormone that is generated when the brain anticipates a reward and is linked to enjoyable behaviors like eating and shopping. This can make us crave more junk food to feel the same way again. Too much junk food consumption can also lead to constipation and tooth disease in the long run. For instance, soft drinks’ high sugar and acid content can erode the enamel’s protective layer, leading to tooth disease. Junk food is frequently deficient in fiber, which has long-term detrimental effects on gut health.
Consider how processed food is when determining whether it is junk food. When we consider foods in their complete and unaltered states. Such as a fresh tomato, a grain of rice, or freshly squeezed cow’s milk. We can begin to envision the number of processes required to convert that whole meal into something that is ready to eat, tasty, practical, and has a long shelf life.
According to Australian dietary recommendations, boys should consume 8,200–9,900 kJ/day, or 1,960–2,370 kcal/day. while girls should consume 7,400–8,200 kJ/day or 1,770–1,960 kcal/day. Of course, your energy requirements increase as your physical activity level increases. Just keep in mind that while occasional consumption of junk food is acceptable. It shouldn’t account for more than 10% of your daily caloric intake. This might be a quick snack throughout the day, such as a little muffin or a few chocolate squares. This might include consuming no more than two fast-food meals per week. The five food groups should make up the remaining 90% of your diet.
We can conclude that junk food is delectable, inexpensive, and practical. This makes it challenging to control how much junk food we consume. However, there may be detrimental effects on our health if junk food becomes a regular part of our diets. We should aim for meals with modest amounts of sugar and salt, whole grains, vegetables, and fruits, as well as foods high in calcium and iron. A strong body and brain are aided by a diet rich in healthy foods. Individually, based on our eating preferences, or through government regulations and health promotion initiatives. We can limit our intake of junk food.
Governments are necessary to stop fast food chains from marketing to young people and to assist us in removing fast food joints and replacing them with healthier alternatives. Researchers may concentrate on spreading awareness of healthy food options and promoting good health. And they can collaborate with young people to create solutions. Together, we can guide young people all across the world in choosing foods that will enhance their short- and long-term health.
