As we mentioned, fenugreek contains 4-hydroxyisoleucine, the amino acid responsible for encouraging the production of insulin and lowering the rate of glucose assimilation in the intestines. This can be of particular benefit to those with diabetes for stabilizing blood sugar levels.
In one study , using the amino acid extracted from fenugreek seeds, it was concluded that "4-hydroxyisoleucine insulinotropic activity might, at least in part, account for fenugreek seeds' anti-diabetic properties."
In addition, the presence of galactomannan in fenugreek furthermore slows down the rate of blood sugar absorption. The sprouts or seeds can therefore be added to meals as a potentially effective way to prevent blood sugar spikes from high glycemic foods.
The diosgenin compound has been shown to help reduce the level of serum cholesterol. In addition, other saponins and extra components like polysaccharides, pectin, hemicellulose and mucilage are found to help lower the "bad" cholesterol (LDL) by binding to and eliminating toxins while inhibiting bile salts from being absorbed in the colon.
