Glass of wine is fine lucy. Not sure if your hubbies wine is "the real thing" or not, although I'm sure it's fine, but the general rule is that the stronger the alcohol, the less carbs it has, as the carb content is sugars which are brewed out as they turn to alcohol. So spirits, like vodka or whisky, have zero carbs. Wine has some, beer has more. Even when carbs ARE present though, you will tend to get lower BGs. That's because the liver always processes toxins firast before it bothers about converting carbs to glucose, and it sees alcohol as a toxin. I don't drink alcohol deliberately to lower my BGs, but on the days when i DO have a drink, I have my more carby meals to take advantage! This alcohol effect is why people on insulin need to be wary of hypos when drinking; I believe a lot of them use less insulin per amount of carbs of they are having a drink. Obviously, drinking loads and getting low BGs is no good if you also turn your liver to mush, and there is evidence that LONG TERM HEAVY drinking can increase insulin resistance. So all i moderation I giuess - with the occasional mad party!
So, enjoy your wine! Providing it's alcoholic!
