Therefore, soy lecithin can effectively reduce excessive blood lipids and cholesterol, thereby preventing and treating cardiovascular and cerebrovascular diseases caused by them.
3. Strengthen brain function
The adequate supply of soy lecithin can ensure sufficient choline and “acetyl” in the human body to be synthesized into “acetylcholine”, thus providing sufficient information transmission substances for the human brain, thereby increasing the activation degree of brain cells and improving memory. and intelligence level.
