1. Eat raw or cooked? Eat raw garlic for better results. The best way to eat garlic is raw, and it is best with garlic puree. This is because garlic contains two effective substances, allicin and alliinase. Once the garlic is crushed, they come into contact with each other, thus forming allicin. Allicin has a strong antiseptic effect, but it will lose its effect quickly when it encounters heat, so it is better to eat raw garlic than cooked garlic. 2.Eat the whole clove or chopped? It is better to eat it chopped. The effectiveness of garlic is attributed to the fact that it contains a variety of chemical components, including mainly sulfur-containing organic compounds and saponins. Sulfur-containing organic compounds are important active substances, mainly including allicin and allicin. Allicin is not present in intact garlic, but is produced after being cut or crushed, when the allicin contained in the cells meets with alliinase and undergoes a catalytic cleavage reaction. Therefore, in order to better preserve the active ingredients of garlic, it is recommended to cut or crush garlic and leave it for 15 minutes before eating or cooking. 3. How much is the best amount to eat per day? 2~3 cloves. Allicin has a certain stimulating effect on the stomach and intestines, and eating too much garlic raw can easily cause acute gastritis, and long-term overconsumption can also easily cause eye discomfort. For people with poor gastrointestinal function, it is best not to exceed 1 clove per day; for people with good gastrointestinal function, it is best to have 2~3 cloves per day.
