Grape Seed And Tea Supplement For Healthy Blood Sugar

grape seed extract pre type 2 diabetes diet plan supplementGrape seed and green tea extracts appear to play a role in slowing the rise in blood sugar after a meal by inhibiting certain starch digesting enzymes – Sipping a spot of tea with your food can add a positive touch to your prediabetes diet plan for stopping prediabetes metabolic syndrome.

Researchers have evaluated the apparent ability of grape seed, green tea, and white tea extracts – and their bioactive flavonoids known as catechins – to inhibit the activity of two major enzymes required for people to break down and digest starch.

The results showed that grape seed and green tea extracts inhibit starch digesting enzymes suggesting that a grape seed or green tea supplement could play a possible supportive role for healthy blood sugar control.

The efficacy and potency of the grape seed and tea extracts were compared to the efficacy of a prescription drug known as acarbose which is sold under the trade name Precose. Precose is a prescription inhibitor of starch digesting enzymes prescribed to help maintain healthy blood sugar levels as part of a prediabetes and type 2 diabetes diet plan.

The two enzymes that are inhibited by green tea and grape seed extracts are α-amylase and α-glucosidase.

Grape Seed and Green Tea Science Explained

An enzyme called alpha-amylase from your pancraes breaks down complex starches to simpler starches (oligosaccharides) in the small intestine, and alpha-glucosidases break down the simpler starches into even simpler starches, and eventually to glucose and other monosaccharides in the lining of the small intestine where they are absorbed.

Acarbose is a complex oligosaccharide that delays the digestion of ingested carbohydrates by competing with the carbs that you have eaten.  If the enzymes are working on acarbose, it is hoped that the digestion of some of the carbs that you have eaten will be slowed down or possibly be passed out without giving you any of their calories. This results in a delayed glucose absorption and a lowering of blood sugar levels after you have eaten.

The grape seed and green tea extracts are not oligosaccharides like acarbose so they are inhibiting the starch digesting enzymes some other way, but apparently having the same effect as the Precose drug…interesting
