Chocolate is a favorite food of many adults and children. It can relieve stress and make the body and mind happy, but the benefits are not limited to that. According to a study released by the medical journal JACN (Journal of the American College of Nutrition), every day Eating a 1.6-ounce piece of dark chocolate, equivalent to 45 grams, is very helpful in preventing strokes. Nutritionists point out that chocolate contains flavonoids, which can help control blood pressure and cholesterol and reduce the risk of stroke. Chocolate contains flavonoids, which help control blood pressure and cholesterol and reduce the risk of stroke.

This "Chocolate Prevents Stroke" study was completed by the University of California, San Francisco. Researchers evaluated the vasoconstriction and diastolic conditions of all subjects. Vascular stiffness represents the possibility of vasoconstriction. Symptoms of atherosclerosis; the subjects were then divided into two groups. One group ate 1.6 ounces of dark chocolate every day. Researchers found that those who ate dark chocolate had less blood flowing through the largest artery in their brains. The speed is better than that of the subjects who did not eat chocolate.

Flavonoids are the key to increasing arterial blood flow

Nutritionist Hou Minyi pointed out that the most critical reason why chocolate can improve blood flow is that it contains flavonoids , can increase the oxygen content in the blood, reduce the carbon dioxide content, and promote arterial blood flow, and the improved blood flow is beneficial to the heart and brain cells.

There are more flavonoids in concentrations above 70%

However, not all chocolate is effective. Nutritionists say that dark chocolate contains more cocoa powder, and the flavonoids in it are The proportion of flavonoids is high. In other flavored chocolates, almost half of the flavonoids are destroyed during the production process. Therefore, since you want to incorporate chocolate into your daily anti-stroke health care, you must eat dark chocolate, and it is recommended to choose a concentration as high as 70 % or above, the content of flavonoids contained in it is higher, and the health care effect can be achieved.
