Things like Junk food are horrible and cause a large portion of America to be Obese .Junk Food also hurts things like your liver and can add lots of weight to your body . So many people are Obese in America It is said that 42% of the population will be obese by 2050. If children in this generation eat junk food regularly they will gain 6 lbs. every year. They will also eat around 280 extra calories a day which will hurt their entire body. Obesity increases your risk for cardiovascular disease, diabetes and many other chronic health conditions. Junk food might even lead to depression for teenagers Hormonal changes at puberty make teens more susceptible to mood and behavioral swings. Consuming trans fats, saturated fats and processed food is associated with up to 58 percent increase in risk of depression. Your insulin levels become elevated when you eat processed sugars, such as those in soft drinks, white flour and other foods devoid of fiber and nutrients necessary to properly metabolize carbohydrates. Eating junk foods throughout the day causes chronically high insulin levels, which eventually prompts your cells to begin to ignore this important hormone, resulting in a condition known as insulin resistance. Ultimately, obesity and Type 2 diabetes may set in. Since the 1980s, Type 2 diabetes, which was minimal in teenagers, has risen to 15 percent. High sodium levels are a defining characteristic of many junk foods and one of the contributing factors to the overconsumption of salt that typifies the Western diet and contributes to high blood pressure and heart, liver and kidney diseases, according to Harvard Health Publications. The average American eats five to 10 times more salt than the 2,300 milligrams per day recommended by the U.S. Dietary Guidelines for Americans. Considering the high rates of high blood pressure among Americans, that level should be even lower -- about 1,500 milligrams per day -- for 70 percent of adults. However, the trend since 1988 shows that fewer people with hypertension adhere to a low-sodium diet now than did then. Processing that removes vitamins, minerals and fiber makes junk foods into the sources of empty calories that nutritionists disparage. Children who eat a lot of junk foods may develop nutritional deficiencies that lead to low energy, mood swings, sleep disturbance and poor academic achievement, among other health conditions, according to the University of New Hampshire Cooperative Extension. These are most of the things that can happen if you eat junk food regularly. If children eat like this they are probably going to have many problems with their body and other things that can kill them and make them obese.
