A recent study said tea leaves have numerous health benefiting properties. Popularly known for its caffeine effect, which gives you that instant energy boost, it is also an excellent source of antioxidants. Antioxidants are essential for the body because they help fight against free radicals that are known to increase risks of cancer and heart diseases.
The study, appearing in Asia Pacific Journal of Clinical Nutrition, indicated that the tea leaves contain natural plant compounds-polyphenols, that significantly reduce the amount of glucose among adults, who were given sucrose-laden drink jus before. As reported by the study, polyphenols tends to block sugar absorption in the blood.
The study also claimed that consuming tea aids in smoothing out the spikes in blood sugar levels, triggered by snacking sweet treats.
Dr Tim Bond of the Tea Advisory Panel said, “After water, tea is the second most commonly consumed beverage in the world and this new research adds to already published studies which suggest that it is good for health and well-being benefits,” adding, ” In effect, these polyphenols seemed to lower the Glycaemic Index–the relative ability of a carbohydrate food to increase the level of glucose in the blood–of the sugary drink.”
The study based its results on the effect of tea on 24 participants. While half of them had normal blood sugar levels, the other had already been diagnosed with pre-diabetes
The day before each trial, both groups were asked to avoid any exercise and eat moderately. All that they were given was small low-sugar evening meal. The following morning, their blood samples were taken when they were in a fasting state.
They were given a sugary drink accompanied by a beverage containing either a high or low dose of tea polyphenols or a placebo. Further blood samples were taken 30, 60, 90 and 120 minutes later. . The experiments with their blood samples were conducted thrice, with a gap of one week.
The results indicated both doses of tea polyphenols showed the same significant suppression of blood sugar spikes.
