How to eat tomatoes with nutrition?

Tomatoes contain a certain amount of vitamins and dietary fiber, just like other vegetables. But besides vitamins, tomatoes also contain lycopene. Lycopene is a natural pigment that turns tomatoes red. Its function in human body is similar to carotene, and it is a strong antioxidant, which may prevent cardiovascular diseases and some cancers to some extent. It has been reported that men who eat a lot of tomatoes have a relatively low risk of prostate cancer, which is related to the antioxidant components of lycopene in tomatoes.

Tomato PK ketchup

Compared with tomatoes, the content of lycopene in concentrated tomato sauce is higher. But tomato sauce loses the dietary fiber contained in fresh tomatoes. Therefore, experts say that fresh tomatoes and ketchup can be eaten, and it is best to eat both properly.

Eat raw PK cooked

Tomatoes can be eaten raw or cooked. These two ways of eating are good for your health, and you can choose according to your own preferences. According to experts, both lycopene and carotene are soluble in oil, so it is good to fry tomatoes or make soup, and the absorption rate of raw food is low. If vitamin C is ingested, it can be eaten raw or cooked, because the high acidity of tomatoes is conducive to the stability of vitamin C, and the loss after cooking is relatively small. If it is to obtain potassium and dietary fiber, you can eat it raw and cooked.

Tomatoes are cold and have the functions of clearing away heat and cooling blood, promoting fluid production and quenching thirst. If you are thirsty, eat a tomato, which is very comfortable. But for people who are afraid of cold, cooked food is the best choice, and eating raw food is easy to be unbearable, leading to diarrhea.

Health tips

When eating tomatoes, it is best not to peel them, because the skin of tomatoes also contains vitamins, minerals and dietary fiber. In addition, you should pay attention to washing raw tomatoes.

Rumors about tomatoes

As for the saying that "tomatoes contain nicotine, if eating tomatoes raw is equal to smoking, it is easy to cause cancer", experts said that the nicotine content in tomatoes is very small, which is not the same as that in cigarettes, so there is no need to worry.

How to choose tomatoes

There are many varieties of tomatoes. Strong red, rich in lycopene, is good for cancer prevention. Pale yellow contains only a small amount of carotene and no lycopene. Oranges have less lycopene, but higher carotene. The sugar content of small tomatoes is higher than that of large tomatoes, so they are suitable as fruits, but the calories are also slightly higher. Others, such as vitamins, vary with varieties and cultivation methods and cannot be generalized. Fan Zhihong thinks that in order to meet the demand of vitamin C, all kinds of tomatoes are good, and the key is to choose the ones that are ripe in the season, because the vitamin content that are ripe in the season is higher than that cultivated in greenhouse. If you want to supplement antioxidant components such as lycopene and carotene, you should choose crimson or orange instead of pink or yellow.
