May lower blood sugar levels

Elevated blood sugar levels can put you at risk for health problems including type 2 diabetes, obesity, cardiovascular disease, renal failure, and depression. Sugar consumption, particularly from sweetened beverages, has been found to raise blood sugar levels and the risk of type 2 diabetes. When you eat sugar, your pancreas releases a hormone called insulin. Insulin permits sugar to enter cells, including muscle and liver cells, where it is stored as glycogen or energy. When the body requires energy, a separate hormone, glucagon, is produced to aid in the breakdown of glycogen and the release of energy. If you ingest more sugar than your body has glycogen storage room for, the extra sugar is stored as fat.

According to research, drinking black tea may help reduce your blood sugar after a meal or snack, commonly known as postprandial glucose. One modest but well-designed study investigated the effect of drinking black tea on blood sugar levels after consuming a high-sugar beverage. Twenty-four patients with and without pre-diabetes were given a high-sugar beverage coupled with a low- or high-dose of black tea or a placebo. Those who had a low- or high dose of black tea had considerably lower postprandial (after-meal) blood sugar levels than those who consumed a placebo.
