However, this benefit is not for everyone, especially those who are taking insulin or hypoglycemic drugs should be very careful because of the risk of late blood sugar drops.
Contains resveratrol, a beneficial antioxidant compound, helps stabilize nails, lower blood sugar
Resveratrol, a natural polyphenol in red grape skins, has the ability to: Increase insulin sensitivity. Reduce oxidative stress a factor that promotes insulin resistance. Inhibit the breakdown of glucose in the liver, helping blood sugar to be more stable, supporting lowering blood sugar.
Some small studies show that resveratrol can reduce HbA1c and fasting glucose in people with prediabetes.

Red wine has a GI of almost 0
wine is carb-free or contains very little (if not mixed with sugar), so it does not increase blood sugar after drinking.
In some studies, drinking red wine at dinner helps reduce blood sugar the next morning (but this effect is not stable).
Risk of late blood sugar drops, especially for people with diabetes
Alcohol inhibits the liver from producing glucose, causing people taking insulin or hypoglycemic drugs to be at risk of losing blood sugar after 612 hours, especially when taken on an empty stomach.
This is a late form of hypoglycemia, difficult to detect and can be dangerous if you sleep drunk.
So how should you drink wine?
According to experts, women should only drink a maximum of 1 glass/day (about 150ml).
Men should only drink a maximum of 2 glasses/day (about 300ml).
You should drink it during meals, not mix it with sweetness, and do not drink it on an empty stomach.
Red wine can indirectly support the control of hypoglycemia if used in moderation, thanks to the compound resveratrol and its properties of not increasing blood sugar.
A glass of red wine for dinner helps lower blood sugar levels, reduce the body's insulin needs, and increase insulin sensitivity.
When you drink red wine every day for 2 weeks, insulin resistance has improved. Reducing insulin resistance helps the body regulate blood glucose levels, reducing the risk of type 2 diabetes complications.
However, it should not be used as a "treatment", and people with diabetes and insulin users should consult a doctor before taking it.
People with diabetes need to have a healthy diet and exercise regularly to increase resistance and prevent dangerous complications of diabetes.
