Like "If I can remember the information correctly, the green and white teas are good for a few things from bloop pressure, diabetes, cardiac, and others. The type of teas are important. The black, orange, and other teas are more caffeinated and because of the caffeinated things is what is not good for us. I do remember talking to some people that depending on metabolism, carbs will vary with how they will affect bs/bg levels and the amount of time it can take for the levels to go down. I do not have to test and am maintaining with diet and exercise. I can't help but think that more relaxed we are, which teas can help with, will also affect our body and our body affect our bs/bg."
