Too much added sugar harms overall health. As a source of readily available energy, sugar is naturally found in all foods that contain carbohydrates. Fruits and vegetables, grains, and dairy contain sugar in abundance. Consuming whole foods that contain natural sugar is healthy as plant foods also possess high amounts of fiber, essential minerals, and antioxidants. Milk and other dairy products are good sources of protein, vitamins, and minerals such as calcium. Our body digests these foods slowly, and the sugar in them provides a steady supply of energy to the cells. Thus, the intake of fruits, vegetables, and whole grains has been found to reduce the risks of non-communicable diseases such as diabetes, heart disease, and cancers.
