Drinking black tea may be beneficial for people with diabetes, as it appears to stimulate an insulin response and reduce blood sugar levels, according to researchers from King‘s College London and the University of Central Lancashire.Sixteen participants drank glucose in either water, water plus a small amount of caffeine, or water plus instant black tea.After two hours, plasma glucose concentrations were significantly reduced in those who consumed 1 gram of tea, compared to the plain water and caffeine drinks. Drinking black tea also increased insulin levels compared with the other drinks, after 90 minutes.Tea’s protective benefits have been linked to polyphenols, including:
ISLANDER,
May I ask why your BG is so high if you do not use any sweets?
Thanks so much for the test #'s that is AMAZING. If your fasting BG is 146 absent of sugars, what the heck would your system do with something like a port wine?? I find this topic extremely fascinating, and I do not have diabetes. My fasting BG is 87.
There is a possibility of iron overload if you've tried everything else to increase insulin sensitivity. According to Dr. Richard Bernstein, in his book, "Dr. Bernstein's Diabetes Solution," (pp. 247-248) he states too much iron in your body will make you insulin resistant. If in the past you've used cast-iron skillets or taken regular supplements with added iron, then you may be at risk. Iron is not easily depleted from the body and builds up over time, and contributes to many health conditions. You may need to get your serum ferritin level checked out and be asked to donate blood or undergo therapeutic phlebotomies. Dr. Bernstein recommends donating blood every two months to maintain optimal insulin sensitivity.
Does anyone know why green tea would cause nausea? I used to think it was because the green teas I occasionally tried weren't organic/good quality. But after reading an article by Dr. Mercola last month, I bought a really high quality, organic macha from Japan. It made me severely nauseated for two hours after I drank it. I mentioned this to a friend, and she said that she gets this same reaction from green tea. Is this common? I have no trouble drinking black teas.
This is called a "clue". You do not have to know why it is causing it only that your body is screaming at you to stop it immediately. Everyone is different, there are nearly limitless permutations of genetic combinations that make it impossible to predict these types of reactions. The beauty of natural products is they typically give you mild and NON fatal hints to stop. Unlike many drugs which can kill you.
So, bottom line stop the green tea ASAP, and if you purchased it from us return it for a full refund.
Anna, when I first tried green tea many years ago, I found that hot tea made me very nauseas, but I handled it cold vey well. So for years I drank 2-3 iced green teas, usually Celestial Seasonings, sweetened with stevia. In 2005 I started drinking hot Chai tea as well, which i tolerated well. All of a sudden any tea at all made me extremely nauseas, which has continued to this day. Needless to say, I no longer drink tea.
Anyway I haved searched the web from time to time, looking for anyone who has had the same reaction, and a clue as to why. I have come up empty. Its just nice to know i'm not the only one.
I too have the same problem, if any one knows I am interested also.

Occasionally green tea will make me nauseated. I found that a few things will eliminate this 1) don't drink it on an empty stomach and 2) Don't steep the tea for so long (try about 1 minute).
Green and White teas have less of a steeping time than regular black tea and are intended to have more delicate flavors as the leaves have not been fermented. Green tea becomes bitter when steeped too long!
I recently bought some matcha green tea, and had been drinking a couple of cups a day for two days when on day 3 I made a 32-ounce bottle of iced tea with probably half a teaspoon of tea in it. About 20 minutes later, I became nauseous and it came up. I've been trying to find out why it could do this but have no idea yet, but in this instance I did have the tea on an almost-empty stomach, and I'm guessing that's a factor. I'll be trying the tea again in much, much smaller amounts, maybe one cup a day on a full stomach, max. I just read a study about how too much green tea (such as in those mega-dose supplements) can cause liver toxicity in animals, so I'll be keeping my intake to below 500 grams a day - assuming I can tolerate it at all.
