Something else on the legitimacy of the "French Paradox". Usually, the French cuisine (rich sauces, gourmet cheeses, and such like) should lead to a high incidence of coronary high disease. The fact that it doesn't can be traced to the high consumption of resveratrol-containing red wine with their meals. As is well known, the consumption of plant polyphenols (from green tea, red-wine, apple, cocoa, and so on) with meals reduces what is known as post-prandial (after-meal) blood sugar and oxidative stress levels. When we eat, we might end up overeating, leading to post-prandial endothelial disorders that can impact us during most of the day. "Post-prandial oxidative stress" refers to the condition triggered by overloading our blood with fats and sugars for extended periods of time. This produces damage to the arterial wall (also due to high LDL oxidation), and can end up in higher risk of atherosclerosis, obesity, and diabetes.
Consuming plant polyphenols (in the French case, wine polyphenols) with meals can help prevent these markers of dysfunction, helping the French to stay healthy. Even if one does not have the habit of drinking wine during meals, one can supplement with green tea extract and cocoa polyphenols after meals to obtain the same benefits.
