Junk food contains high levels of calories from sugar and fat but little protein or vitamins. Studies show that 60% of people suffer from diabetes and obesity due to overeating junk foods. Junk food is attractive because it is quick, easy, cheap, and tastes good. However, eating junk food can lead to lack of energy, poor concentration, vitamin deficiencies, obesity, high blood pressure, high cholesterol, osteoporosis, heart attacks, and other diseases. People should eat a variety of nutritious foods instead of junk food for better health.
