Is red wine GOOD for diabetics? Study claims the tipple’s main antioxidant can help reduce artery stiffness for type 2 sufferers This is great, but it isn't really talking about wine, per se. It is talking about resveratrol. It doesn't clarify if a person needs to drink hundreds of bottles of wine just to ingest the same amount of resveratrol in the supplement/s, in which case the diabetic would die from the alcohol and the calories. Also, it is known that grapes and raisins are very bad for dogs. It is also known that alcohol is very bad for dogs. But I have never heard if wine is doubly toxic to dogs because of it's origin from grapes - or does the toxic substance fade away in fermented wine? This is something worth knowing.
