Chocolate has relatively low protein content, but high fat content. Chocolate is a natural defender against heart disease. It is rich in multi-source phenol complexes, which play a considerable role in preventing the oxidation or accumulation of fatty substances in human arteries. <br /><br />The main disease of heart disease, coronary heart disease, is usually caused by the oxidation of the fatty substance LDL (low-concentration lipoprotein) in the human blood and the formation of obstacles, causing cardiovascular obstruction. <br /><br />The phenol complex of chocolate not only prevents the fat of chocolate itself from corrupting and turning sour, but also can be quickly absorbed into blood vessels after being eaten into the human body. The antioxidant content in the blood increases significantly, and quickly acts as a powerful antioxidant that prevents LDL oxidation and inhibits the activity of platelets in blood vessels. These subsubstances play an important role in keeping blood vessels smooth.
