Fast food has increasingly become a significant part of the American lifestyle. In 1970, there were about 30,000 fast-food restaurants in the United States; that number increased to 222,000 by 2001. This growing trend is concerning as many health consequences come along with a diet full of fast food.
Heart Disease
Fast food can cause high blood pressure and obesity, due to the high amounts of salt and fat in the food -- two major risk factors for heart disease. In 2010, 36.9 percent of Americans had heart disease, a number the American Heart Association projects will climb to 40.5 percent by the year 2030. In a study conducted by the American Heart Association, researchers monitored the effects of the American fast food diet on Southeast Asian populations. Research showed that people in this population who ate fast food at least twice a week were 56 percent more likely to die of heart disease.
Fat
While fast food items such as hamburgers and french fries, Mexican and Chinese food and pizza only contributed 1.9 percent of an American’s total fat calories in 1965, by 1996 those foods added up to 10.8 percent. Since fast foods are full of saturated and trans fats, this is an increasing problem, as these fats contribute to unhealthy cholesterol levels and other heart disease risk factors.
