Comparing the GI values of a few common foods

Table 8-1 shows the GI values of several common foods. A high GI is in the range of 65 to 100, a medium GI is the range of 45 to 64, and a low GI is in the range of 0 to 44. You can see that plenty of good choices are in the medium- and low-GI categories. With the exception of milk, you could say that you should avoid the white foods: potatoes, white rice, and white bread.

Some foods can't be given a GI value because they have so little carbohydrate. Examples are beef, chicken, fish, vegetables, and alcohol. They don't affect blood glucose immediately, but the fat in beef and the empty calories in alcohol make them poor food choices anyway. (See Chapter 12 for information on alcohol use.)

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
