Diet-related diseases like coronary heart disease and obesity are on the rise due to decreasing physical activity and increased consumption of fast food and processed foods. Lack of exercise is caused by more sedentary lifestyles and jobs as well as increased use of automobiles and technology. Overeating high fat, high sugar foods leads to weight gain and health issues like high blood pressure, diabetes, and heart disease over the long run. Religious groups like Buddhism, Hinduism, Islam, Judaism, and Sikhism each have their own dietary requirements and restrictions.
