My grandma says eating these things is good for your health, and you can keep healthy in this way.
My grandmother also said that the living standard of her generation is still very limited, and there is not much money to buy big fish and big meat. Eating these is more cost-effective, and it can be good for your health without spending too much money.
The temperature in winter is very cold, and our blood vessels contract like hot expansion and cold contraction, which makes our blood pressure higher. In addition, people like big fish and big meat, which leads to the rise of various blood indexes and is harmful to health.
Eating these will not raise blood pressure, but will reduce the burden on the body and regulate the body. So many people eat these in winter and are used to keeping fit in this way.
