Insulin Resistance (cont.)

Is there a special diet plan for treating insulin resistance?

The need for insulin can be reduced by altering the diet, particularly the carbohydrates in the diet. Carbohydrates are absorbed into the body as they are broken up into their component sugars. Some carbohydrates break and absorb faster than others; these are referred to having a high glycemic index. These carbohydrates increase the blood glucose level more rapidly and require the secretion of more insulin to control the level of glucose in the blood.

Examples of carbohydrates with a high glycemic index that rapidly raise blood glucose levels include:

  • Unrefined sugars (such as fruit juice and table sugar)
  • White bread
  • Unrefined corn and potato products (such as bagels, mashed potatoes, doughnuts, corn chips, and French fries)

Examples of foods with a low glycemic index include:

  • Foods with higher fiber content (such as whole grain breads and brown rice)
  • Non-starchy vegetables (such as broccoli, green beans, asparagus, carrots, and greens). These are low in calories and in total carbohydrates, and contain vitamins and fiber.

Since foods are rarely eaten in isolation, it can be argued that the glycemic index of each food is less important than the overall profile of the whole meal and associated drinks.

What foods help prevent type 2 diabetes?

Foods that are particularly helpful for people trying to prevent type 2 diabetes and maintain a healthy weight are similar to the low glycemic index foods described above:

  • Vegetables and fruits, which provide fiber and vitamins
  • Fat-free or low-fat dairy products to provide calcium and strengthen bones. Full-fat dairy products should be avoided as high-fat foods can worsen insulin resistance.
  • Whole-grain products, which have a lower glycemic index than refined grains and are rich in fiber
  • Nuts, which contain fiber, protein, and healthy fats
  • Fish, such as salmon, herring, mackerel, or sardines, is a source of "good" (heart-healthy) fats
  • Lean meats or beans are an excellent source of protein

Several studies have confirmed that weight loss - and even aerobic exercise without weight loss - increases the rate at which glucose is taken from the blood by muscle cells as a result of improved sensitivity.

What about exercise to treat insulin resistance?

Two important studies have assessed ways to prevent type 2 diabetes. Both assessed patients who could not control their blood glucose levels, which, for the purposes of this discussion, can be considered the same as patients with insulin resistance. One study, performed in Finland, showed that changes in diet and exercise reduced the development of type 2 diabetes by 58%. The Diabetes Prevention Program (DPP) study performed in the U.S., showed a similar reduction in type 2 diabetes with diet and exercise.
