Group with diabetes mellitus
Dietary Supplement: Trigonella foenum-graecum (fenugreek)
2 slices of bread containing 5 grams of the natural herb fenugreek 2 times, 1 week apart

Detailed Description:

Trigonella foenum-graecum (fenugreek) has been used in traditional medicine for the treatment of diabetes. Fenugreek has been demonstrated to lower blood glucose in response to a glucose load while leaving the levels of serum insulin unaffected in rodents. This effect of lowering blood sugar without changing insulin levels demonstrates improved insulin action. Fenugreek has also been shown to decrease glucose absorption by inhibiting intestinal disaccharidases. Fenugreek decreases glycohemoglobin in diabetic rodents. An amino acid extracted from fenugreek seeds, 4-hydroxyisoleucine, decreases glucose and insulin in diabetic rodents, improves glucose tolerance and stimulates insulin secretion from isolated pancreatic rodent islets.

Fenugreek imparts a bitter taste to products into which it is placed, and this property has limited its use in treating diabetes. Dr. Losso and his associates developed a process that allows incorporation of fenugreek into bread and other bakery goods without imparting a bitter taste, and the success of this process was confirmed in taste testing. This study is designed to evaluate the effect of fenugreek bread made by Dr. Losso's proprietary process on glucose and insulin.
