Commenting on this new research evidence, Dr Catherine Hood from the Tea Advisory Panel (TAP) notes: “Diabetes is a condition of disordered glucose metabolism. The main source of glucose in the body comes from the digestion and hydrolysis of dietary carbohydrates.
“The digestive enzymes pancreatic alpha-amylase and the intestinal alpha glucosidases are responsible for digesting carbohydrates to form glucose.
“Inhibition of these enzymes and hence the inhibition of glucose formation could contribute to the prevention and management of type 2 diabetes.
“Research is continuing on the potential effects of black tea on carbohydrate and glucose metabolism, but this study adds to a growing body of evidence that black tea may contribute to diabetes prevention and management. The findings from these two studies are not new. Black tea has previously been shown to inhibit alpha-amylase and alpha-glucosidase.
“This research provides encouragement to Britain’s black tea drinkers suggesting that black tea is a healthy, hydrating beverage that could help to control the digestion of carbohydrates and hence have a role in helping to manage type 2 diabetes and in some cases present the disease.”
In summary, Dr Tim Bond from TAP notes: “Tea is a very popular beverage in the UK and these latest findings together with many other published studies continue to suggest that Britain’s’ favorite beverage is good for our health including our heart and vascular system.”
