Effects of Green Tea on Diabetes

Green tea has been used as a medicinal aide for centuries, but here in the Western world we’re only just beginning to understand its effectiveness. One of the surprising benefits of green tea could be its effect on diabetes, with it long being used as a traditional way to control blood sugar levels in Japan. And now, studies are being conducted to confirm this as a valid treatment.

One such study was conducted by Iso et al at the Osaka University Graduate School of Medicine . It was based on the idea that coffee can be used as a way to reduce the incidence of type 2 diabetes, and they wanted to look at the effects of other caffeine-containing drinks including green tea.

They took 17,413 participants and gave each one questionnaires relating to their consumption of caffeine-containing beverages and any incidence of diabetes. They then conducted follow-up studies over the next 5 years and noted the occurrence of diabetes, finding that increased consumption of green tea (more than 6 Japanese cups per day/3-4 in the USA given the differently-sized cups) was closely related to a reduced risk of diabetes, even after adjustment for other risk factors.

Another study looked more specifically at blood glucose levels to see if green tea was associated with reduced levels and subsequently a reduced risk of developing diabetes. The cross-sectional study, conducted by Maruyama et al , compared biomedical measures of blood glucose levels with self-reported consumption of green tea. The research team found that consuming high levels of green tea could reduce blood glucose levels, offering further support for the effectiveness of green tea in relation to diabetes.

So, green tea really can have a positive effect on diabetes and, if consumed in high enough quantities, can significantly reduce blood glucose levels, a key indicator of contracting the condition. But why is that? As with a lot of green tea’s benefits, it arguably comes down to its high levels of antioxidants.

It’s been noted that epigallocatechin gallate (EGCG), one of the most powerful antioxidants found in green tea, can influence the way that glucose is absorbed into the bloodstream and can even enhance the action of insulin on the body, thus being able to reduce blood sugar levels.

As you can see, green tea can have a marked effect on the incidence of diabetes and can be used as a great way to regulate blood sugar levels. Drinking or eating it with meals is said to have the most powerful effect as doing so will reduce the amount of glucose that passes into the bloodstream and will subsequently reduce blood sugar spikes.
