What is diabetes? Diabetes is a condition in which the body either does not produce enough insulin or has become resistant to it. There are two types of diabetes, Type 1 Diabetes and Type 2 Diabetes. Diabetes information can be confusing. These diabetes types are treated differently, with type 1 diabetes care involving diet and medications while type 2 diabetes care usually centers on diet, although diabetes medications may be involved. Diabetes discussion about both types of diabetes must include dietary advice.
