A 20-year study in the United States found that taking at least 300 micrograms of folic acid from food every day can reduce the incidence of stroke by 20% and cardiovascular disease by 13%. The subjects of this study are nearly 1 10,000 Americans aged between 25 and 74. The researchers recorded their intake of folic acid from daily food during the experiment, and found that people who ate a lot of folic acid had lower blood pressure and blood lipid levels. Folic acid is a B vitamin, which exists in citrus fruits, tomatoes, green leafy vegetables, beans and grains. Folic acid can protect the cardiovascular system because it can reduce the level of homocysteine, which is the chief culprit of arteriosclerosis and eventually leads to heart disease and stroke. The American Heart Association recommends that adults take 400 micrograms of folic acid a day and pregnant women take 600 micrograms of folic acid a day.

Remind you: Take more folic acid to prevent stroke. This folk prescription comes from the internet. Please follow the doctor's advice before use.
