With the improvement of living standards, people pay more and more attention to health. Unlike before, they just had enough to eat and drink, but now people's diet is more scientific and healthy, and they pay attention to health preservation. In the past, because there was no economic condition, I would eat and drink as long as I was on holidays, and I never knew how to control myself. Nowadays, people celebrate the New Year almost every day. They can buy anything they want in the supermarket. Because they eat too much, they know that these things are harmful to their health, so they usually do so.

Maybe many people don't know that if vitamin D is lacking, it may lead to obesity, especially female friends. Why do you say that? Because vitamin D is necessary to make leptin, and leptin can control people's appetite. If it is not lacking, then people will not gain weight easily. On the contrary, if it is lacking, people will overeat and get fat easily. Some experts have also shown that vitamin D can delay aging and prolong life, especially for women, so vitamin D should be supplemented.

What do we usually eat to supplement this vitamin? In fact, there are many foods rich in vitamin D, such as fish, animal liver, vegetables, fruits, mushrooms, fat milk, pig liver and so on. These things are what we eat every day. As long as we take a part of it every day, we can supplement the daily vitamin D. Egg yolk and lean nuts also contain a small amount of vitamin D, so no matter adults or children, don't be picky about food, because only a balanced nutrition can meet the daily needs.

I think people's awareness of health care is still quite strong now. Everyone knows that smoking and drinking are harmful to health, so many people will choose to quit smoking. For many office workers, smoking may relieve their work pressure, but I think this kind of thing is an excuse. For me, smoking is harmful. Long-term smoking may lead to lung function damage, which is irreversible.
