hydrate rich meal (rice) with a mixture of green tea, black tea and mulberry, and the amount of breath hydrogen measured. When carbohydrates are eaten, but not absorbed, they ferment in the intestinal system and produce hydrogren, which can then be measured.

In one study, participants were given a carbohydrate rich meal (rice) with a mixture of green tea, black tea and mulberry, and the amount of breath hydrogen measured. When carbohydrates are eaten, but not absorbed, they ferment in the intestinal system and produce hydrogren, which can then be measured. The tea mixture clearly blocked the body from absorbing all the available carbohydrate — exactly the effect we want for weight loss and type 2 diabetes.
