Fiber, especially soluble fiber, lowers elevated blood sugar levels. Fruits, vegetables, and some seeds, such as pectins, gums, and mucilages are good sources of soluble fiber. Flaxseed has one of the highest levels of both soluble and insoluble fiber known for any food. It also contains a substance called lignan, which inhibits breast and prostate cancer.
One test of non-diabetics demonstrated that taking fifty grams of water plus flaxseed mucilage reduced by 27 percent normally elevated blood sugar levels following a high-glucose meal.422 Fenugreek seed, which contains about 50 percent fiber, is another good source of soluble fiber. Similar tests in diabetic patients have found a significant reduction in blood glucose levels.423 Another advantage of increasing fiber intake to control diabetes is that it significantly reduces cell glycation. Remember, this process is responsible for much diabetes-related damage. In addition, a high-fiber diet removes dietary toxins, improves bowel elimination, and reduces the risk of colon cancer.
For a very interesting discussion of the nutritional treatment of diabetes, I suggest a 1997 article by Dr. C. Leigh Broadhurst in the journal, Alternative Medicine Review,424
