As a condition, there are two main types of diabetes where high blood sugar can cause chronic problems such as heart disease, nerve damage and foot ulcers. Type 1 occurs when the body does not make sufficient insulin, whereas type 2 occurs when the insulin that is created does not work as it should. In fact, there is a third form which affects some pregnant women, but dietary advice for this category of people should be always be sought from a medical professional. Overall, food for diabetics means keeping on top of sugar intake and reducing obesity since having too much fat helps the body to regulate its blood glucose levels naturally without so much reliance on insulin.
