The piece of evidence that would best support this claim is; consuming too much sugar over time can lead to diabetes and cardiovascular disease.
Diabetes is a lifestyle disease in which blood sugar or glucose levels are higher than the normal levels. Carbohydrate foods, such as breads, rice, cereals, pasta, among others can cause a rise in blood sugar. There are two types of diabetes; that is, type I and type II, type II is the one linked to high blood sugars.
