Drinking green tea helps to reduce blood sugar spikes

by -

The green tea antioxidant - epigallocatechin-3-gallate or EGCG for short that has been shown to help reduce blood sugar spikes in mice may be useful to improve diet strategies for humans.

[1]Mice fed EGCG and corn starch had a significant reduction in the increase. The dose of EGCG fed to the mice was equivalent to about 1 1/2 cups of green tea for a human. The study showed EGCG was most effective when the compound was fed to the mice simultaneously with corn-starch. For humans this may mean that green tea could help them control the typical blood sugar increases that are brought on when they eat starchy foods. "If what you are eating with your tea has starch in it then you might see that beneficial effect so, for example, if you have green tea with your bagel for breakfast, it may reduce the spike in blood glucose levels that you would normally get from that food."

Adding sugar to your green tea would negate the effect that the green tea would have on limiting the rise in blood glucose level.

  • "I would like to take this opportunity to say a massive thank you to Andrea. When I first saw her, I felt that the only way that I would be able to cope with my future was to resign from my job, which I love, and to stay at home full time because I just felt that I wasn’t performing well as result of feeling constantly totally exhausted and I seemed unable to cope with even minor levels of stress. As a result of her time, dedication and perseverance however, I now feel 10 years younger and am looking forward to what the future might bring both professionally and personally. Thank you for giving me my life back. "
