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.

What was obvious to Andrea was my blood sugar level swings that resulted in me reaching for a high sugar/carb snack whenever I had a dip.  I have followed her advice and lost a noticeable amount of weight, had tonnes more energy and my headaches stopped.
