Folic acid is the "guardian spirit of the fetus", but the elderly are also the key groups to supplement folic acid, Professor Huo Yong, director of the Department of Cardiology and Heart Center of Peking University First Hospital, after years of clinical research, provides us with the most suitable method for Chinese prevention of stroke!
1. Lack of folic acid intake, the probability of stroke increases
Folic acid, also known as vitamin B9, is a water-soluble vitamin. It is purified from spinach leaves and is therefore named folic acid.
The proportion of folic acid deficiency in Chinese residents is as high as 20% to 60%. The lack of folic acid intake in the human body can easily lead to an increase in the content of homocysteine in the blood, and the increase of this substance will directly lead to a sharp rise in the probability of stroke.
Folic acid can improve vascular endothelial function and prevent chronic cardiovascular diseases such as coronary heart disease.
2. Prevent Alzheimer's disease
For middle-aged and elderly people, adequate folic acid can not only reduce the damage of harmful substances in the body to cerebral blood vessels, but also help to reduce the cognitive decline caused by brain nerve damage and Alzheimer's disease.
3. Folic acid helps sleep and improves memory
Once the lack of folic acid, the body's resistance will be weakened, will show mental malaise, fatigue and weakness, insomnia forgetfulness, loss of appetite, some people also have glossitis, diarrhea, pernicious anemia, children and the elderly often appear drowsy or insane.
