Green Tea Can Help Those With Type 2 Diabetes Lower Their Blood Sugar Levels and Improve Insulin Sensitivity

Green tea and diabetes studies show that green tea may regulate blood sugar levels and improve insulin activity up to 15 times for those suffering from type-2 diabetes.


One study, reported by the UK Council on Tea, showed that people who consume green tea regularly are at a lower risk of developing Type II diabetes than those who don’t.

The study conducted on participants aged 40 to 65 who drank black, green and oolong teas showed that drinking at least three or more cups of these caffeinated beverages each day could result in a 33 percent reduction in their risk of type 2 diabetes.

Clinical trials conducted by the University of Geneva and the University of Birmingham indicate that green tea raises metabolic rates, speeds up fat oxidation and improves insulin sensitivity and glucose tolerance. In addition to caffeine, green tea contains catechin polyphenols that raise thermogenesis (the rate at which calories are burned), and hence increases energy expenditure.

Green tea has been used for its medicinal properties for centuries to treat everything from headaches to depression.

Green tea is full of flavonoids, which give green tea its health benefits. These flavnoids, called polyphenols, are potent antioxidants. A subgroup of these antioxidants, called catechins, are abundant in green tea leaves.  One catechin in particular, epigallocatechin gallate (EGCg), is found only in tea and is one of the most powerful antioxidants ever found. It is 20 times stronger than Vitamin E.

Epigallocatechin gallate (EGCG) is a potent anti-oxidants that can protect the liver from toxins and aid in its normal function. Antioxidants mop up the harmful free radicals in the body and can help protect against heart ailments, stroke, arthritis, type 2 diabetes, and degenerative diseases of the nervous system. Theanine, another ingredient in green tea has a calming effect on the human body, and is known to relieve anxiety, and partially neutralize the rise in blood pressure that can occur due to caffeine intake.

The EGCG  in green tea has the ability to help type-2 diabetics break down glucose and lower blood glucose levels.

There is also a suggestion that it can increase endurance in exercise by improving fat metabolism.

Researchers at Sweden’s Karolinska Institute found that the antioxidant EGCG (epigallocatechin gallate) in green tea helped moderately diabetic mice tolerate sugar and produce insulin.

Another benefit of drinking green tea to help control diabetes as opposed to black tea or coffee is that it seems that green tea can help you in managing your weight, which is key to preventing diabetes.

Green tea has thermogenic properties (a thermogenic increases the metabolism of the body’s fat), and promotes fat oxidation beyond that explained by its caffeine content. In a recent study of 60 obese subjects, it was concluded that green tea could reduce body weight by increasing energy expenditure and fat oxidation. In another study involving obese subjects, it was found that continuous ingestion of a green tea extract led to a reduction in body fat. The three ingredients in green tea that promote fat loss are catechins, caffeine and theanine that work by inhibiting the enzymes that digest triglycerides, which play an important role in metabolism as energy sources and transporters of dietary fat.

Doesn’t green tea contain Caffeine?

Yes, green tea does contain caffeine, but the health benefits of green tea far outweigh their caffeine danger.


Tea contains half the amount of caffeine found in coffee, so moderate consumption is unlikely to cause problems to the majority of people.

An average serving of coffee contains the most caffeine, yet the same serving size of tea provides only 1/2 to 1/3 as much

An 8 oz cup, coffee can have about 100 mg of caffeine where green tea only has about 20 mg of caffeine.

Given the amount of caffeine it contains, a cup of tea would normally be enough to produce the stimulant effects typically associated with caffeine. Because green tea also contains theanine, caffeine effects are counteracted and little if any stimulation actually occurs.

Some people who are sensitive to caffeine can’t reap the benefits of drinking green tea. Although green tea has less caffeine than coffee or some other energy drinks, consumers who are sensitive to caffeine can still suffer from sleeplessness, jitters or heart palpitations. The obvious solution is to drink decaffeinated green tea.

A highly recommended decaffeinated green tea extract product is Life Extension Decaffeinated Mega Green Tea Extract.

Green Tea Extract is a decaf option of the ancient herb, offering all the benefits of green tea and none of the jitters. Green Tea Plus contains only trace amounts of caffeine, just enough to provide health promoting benefits—as well as additional nutrients such as trace minerals and is naturally sweetened with Magic Fruit extract for added flavor.

One capsule of Green Tea Extract with 200mg EGCg possesses the phytonutrient content equal to about 2-3 cups of green tea. Green Tea Extracts contains numerous compounds, including Polyphenols and Catechins, that provide potent antioxidant benefits.

Green tea tips

Drink your green tea without milk. Existing evidence seems to say that milk dilutes some of tea’s health benefits, especially for people suffering from heart problems and type 2 diabetes.

Catechins are responsible for the beneficial effects of green tea by stimulating the production of chemical nitric oxide. But animal milk contains proteins called casein. These proteins bind to the catechins, reducing their concentration and effectiveness.

Try using soya milk. Soya milk contains lecithin that has a different molecular structure to casein, and so is unlikely to bind to tea catechin the way casein does.
