Take stock of the six health preserving methods of eating vegetables, wash them first and then remem

Vegetables are rich in vitamins, minerals and dietary fiber. In addition, vegetables also have many health care effects. However, if you want to eat vegetables for health care, you should avoid making some mistakes.

1. Wash before cutting

Most of the nutrients in vegetables are water-soluble. Some people like to clean them after chopping, which will make the nutrients in vegetables lose in water. So the right way is to wash before cutting.

2. Vegetables should be diversified

Picky eating is not a disease, but often picky eating is definitely not so good. We eat more than 100 kinds of vegetables every day. If we want to be healthy, we need to ensure that all kinds of vegetables, such as green leafy vegetables, eggplant and fruit, potato and taro, cabbage, melon and rhizome, are consumed. Because each kind of vegetable nutrition ingredient is different, which lacks is not good to the human body. So if you have picky eaters, get rid of them. It's good to change your taste.

3. The best vegetable is cold mix

In our daily life, almost all people regard 'stir frying' as the preferred way to cook vegetables. Ren Lili, director and Secretary General of Shenzhen nutrition society, said that vegetables will encounter high temperature and oil when they are fried, which will change the taste of vegetables and make the vitamin in vegetables lose too quickly. Therefore, the most healthy way to eat vegetables is cold, even if it is fried, it should be fried with a quick fire. Every 10 minutes, vitamin C will be reduced by 60% or more.

4. Vegetables should not be stored too long

The vitamin content in vegetables is the most abundant, but if the storage time is too long, the vegetables will become flat and even withered. At this time, the non-toxic nitrate in vegetables will be reduced to nitrite, which can make the normal hemoglobin become methemoglobin and no longer have the ability to carry oxygen. In severe cases, it will make people's nails, lips, and even the whole body appear cyanosis, shortness of breath and other symptoms.

In addition, vegetables can not be frozen, storage temperature should not be too low, otherwise it will make vegetables lose flavor prematurely.

5. Don't stay overnight with vegetables

The results showed that the vitamin C of fried vegetables decreased by 20% after 15 minutes, 30% after 30 minutes and 50% after one hour. More serious is to eat overnight vegetables, there will be the risk of food poisoning.

6. Don't eat more vegetables

Although vegetables are healthy, it's wrong to overdose them. Because most vegetables are not easy to digest, and celery, beans contain high crude fiber, eating will induce gastrointestinal diseases, but also cause the burden of the stomach. So the daily intake of vegetables in 300 g - 500 g can.
