Researchers at Hopkins University School of Medicine found that dark chocolate contains a compound that can reduce the degree of brain damage within 3.5 hours of a patient's stroke. Researchers say that eating one serving of chocolate a week can reduce the risk of stroke by 22%.

For healthy people, it is generally ok to eat 20~30 grams a day. It is alkaline. The acidity and alkalinity of food depends on the type and content ratio of minerals contained in food: potassium, sodium, calcium, magnesium and iron present alkaline reaction after entering human body; Phosphorus, chlorine and sulfur are acidic after entering the human body. Chocolate contains 30% fat, of which 60% is saturated fat. However, chocolate saturated fat contains unique stearic acid. It also contains a variety of minerals necessary for good nutrition, including calcium, phosphorus, magnesium, iron, zinc and copper.
