When you don't give your body the proper nutrients, it's unable to function at its best. An unhealthy diet not only deprives you of the nutrients required for energy and vitality, it also introduces unhealthy substances such as trans fat, as well as high levels of saturated fat and sugar. The combination of the two can contribute to obesity, chronic diseases and compromised mental health.
Increase in Obesity
An unhealthy diet is a major risk factor for becoming overweight or obese. Unhealthy diets are often energy-dense, which means they are much higher in calories than nutrient-dense diets that include fruits, vegetables and other fiber-rich foods. When you consume more calories than you burn, the extra calories are stored as body fat. Obesity is a major risk factor for many chronic diseases, including cancer, cardiovascular disease, hypertension and Type 2 diabetes.
Higher Risk of Chronic
DiseasesDiets high in unhealthy substances significantly increase the risk for many chronic diseases. Trans fat, for example, is an artificial saturated fat present in many fried foods, baked goods and packaged junk food. This dangerous fat can increase bad cholesterol while simultaneously decreasing good cholesterol, notes the Centers for Disease Control and Prevention. This artery-clogging effect is strongly linked to heart disease. According to the CDC, trans fats alone are responsible for between 10,000 and 20,000 heart attacks per year in the U.S. According to a 2002 statement published by the American Heart Association in the journal "Circulation," diets high in sugar are also strongly connected to heart disease, diabetes and nutritional deficiency.
