Old people should eat lightly, but exercise is not enough. Just take more walks and do some activities! Cereal powder can also be eaten, after all, this is a light part. In addition, it is best to buy some earthworm filial piety, also called earthworm protein, which has a particularly good effect on the blood viscosity of Sangao. My mother is also eating it. She is in her teens, and every time she goes to the hospital for examination, there is no case of Sangao's blood viscosity. The doctor said that it is rare to have such a good blood quality at such an old age! You can also try it. It's better to buy Japanese ones!
