Diet for the elderly: It is not advisable to eat too much tofu

　　Tofu is a food that is cheap, high-quality, and rich in nutritional value. However, American medical researchers have found that tofu and soy products contain a large amount of methionine. Methionine can be converted into cysteine ​​under the action of enzymes. Cysteine ​​will damage the endothelial cells of the arterial wall, making it easier for cholesterol and triglycerides to deposit on the arterial wall, which may ultimately lead to the formation of atherosclerosis. In addition, tofu is cold in nature and has a cold stomach. diarrhea People who often eat large amounts of tofu will also aggravate indigestion.
