This essay explores the relationship between fast food and the obesity epidemic. Fast food contains alarmingly high levels of fats, carbohydrates, cholesterol and refined sugar, which are loaded with calories, and are the main factors responsible for triggering obesity. The large amounts of empty calories ingested coupled with lack of an active lifestyle and exercise, lead to accumulation of unhealthy fats the body. Cholesterol clogs arteries, leading to severe complications like heart disease. According to statistics released by the CDC1, 26.6% of Americans are obese, and obesity is the direct result of eating improper diet coupled with a lack of exercise. As many as 16% of US soldiers are obese, making it the primary reason for discharging them from duty in the Military. Fast foods lack desirable essential nutrients and dietary fiber, the most important components of a healthy diet. British researchers from the Medical Research Council Human Nutrition Center and the London School of Hygiene and Tropical Medicine have determined that repeated eating at McDonald’s or KFC or Burger King, people are more likely to gain weight and become obese. This is because fast food not only contains many more calories than traditional food but also is more likely to undermine normal appetite control systems. Obesity isn’t the only harmful effect of Fast food consumption. Research done by national and international organizations has revealed indigestible facts about fast foods that most consumers would never have imagined. The USDA in a 1996 study found that at meat processing plants, 78.6 percent of the ground beef contained microbes … spread primarily by fecal material. There is a real shit, not figurative, but real mammal made shit in that burger. This statistic alone made me give up fast food. This indicates that fast food is often contaminated by feces from sewage and other sources. Eric Schlosser, an investigative journalist writes in Fast Food Nation: the Dark Side of the All-American Meal, The medical literature on the causes of food poisoning is full euphemisms and dry scientific terms: coliform levels, aerobic plate counts, sorbitol, MacConkey agar, and so on. Behind them lies a simple explanation for why eating a hamburger can now make you seriously ill: There is shit in the meat. Food contaminated with coliform, that are residents in the digestive tract, is indicative enough about the unclean and unhealthy meats and other products used in the fast food industry that can eventually have serious manifestations on the health of the consumers.
