France is the largest consumer of wine in the world, consuming 78L per person annually. Meanwhile, France is also one of the countries enjoying the longest average life expectancies in the world. Though French are fond of food with high cholesterol, such as cheese, meat and goose liver, the number of people died of cardiovascular diseases is only half of that of the Americans and the English. Thus, scientists found the answer from red wine: wine contains many extraordinary substances. Just red wine juice is favorable to heart: according to the result of an experiment conducted by American scientists, drinking 250g red wine juice everyday can generate great influence on blood platelet and prevent thrombus which can cause embolism. Data shows that grape juice is more efficacious than aspirin in thrombus prevention. Grape juice fermentation gives rise to extremely valuable compounds, which are beneficial to angiocarpy, able to ease oxidizing reaction, clear blocked artery and prevent atherosclerosis and other heart diseases. These substances in red wine enable French gastronomes to enjoy food with high cholesterol without scruples. Wine is a very beneficial beverage, the acidity of which is nearly the same as that of gastric acid, thus benefiting to digestion. In addition, wine also contains rich vitamin B1, B2, B6, B12, etc., which can make one healthy and strong.
