This role is mediated by inhibiting two enzymes α‐amylase and α‐glucosidase leading to management of postprandial hyperglycemia for type 2 diabetes. Therefore, wine is considered an antidiabetic agent and help reduce the associated complications of cellular oxidative stress that result from hyperglycemia.

However, this positive role is related to a moderate consumption of wine as the overconsumption is not advised as said by Graham S. Hillis, director of the cardiovascular division at the George Institute and senior staff cardiologist at Concord Hospital Sydney.

Cardiac disease:

Red wine can lower the risk of coronary heart disease mortality. This is because of its antioxidant and anti-platelet activities that improve the blood circulation and enhance the health of the heart. Moreover, by controlling hyperglycemia, lowering Cholesterol level, and the antiplatelet effect of resveratrol, it reduces the risk of developing atherosclerosis which is the main cause of coronary heart diseases.
