Many people want to know whether tomatoes are cooked or raw. In fact, it mainly depends on what kind of nutrition you want to get. If you want to take vitamin C, it is more suitable for raw food. The vitamin content of tomato is 19mg/ 100g, which is five times that of apple. Although the vitamin C content of tomatoes is not the highest, eating 2-3 tomatoes a day can satisfy people's vitamin C for one day. If you eat apples, you should at least eat 10.
One disadvantage of eating raw tomatoes is that its lycopene can't be released well. Tomato has a high content of lycopene, which has a strong antioxidant capacity, and has a good preventive effect on prostate cancer, breast cancer, cardiovascular and cerebrovascular diseases. If eaten raw, the plant cell wall will not be fully destroyed and lycopene will not be fully released, and the absorption and utilization rate will be reduced. Moreover, lycopene is a fat-soluble vitamin, which can be better absorbed and utilized by adding some oil when eating.
Tomatoes are rich in organic acids, even if cooked, the loss of vitamin C will not be too great, so if you are a person with spleen and stomach deficiency and cold, it is best to cook tomatoes before eating, so as to make better use of their nutritional value.
Chinese medicine believes that tomatoes are sweet and sour, slightly cold, and enter the stomach meridian, which has the effects of quenching thirst, promoting fluid production, invigorating stomach and promoting digestion, cooling blood and calming liver, clearing away heat and toxic materials, and lowering blood pressure.

Tomatoes are a kind of food with very rich nutritional value. You may eat them every day, but you may not understand their nutritional value:
Different from other vegetables, tomato is a "cross-border star", wandering in the fields of vegetables and fruits. When can fruits be eaten raw and vegetables cooked? Raw and cooked foods have their own nutritional value, which is incomparable to other vegetables and fruits. Whether they are eaten raw or cooked depends on which nutrients you need more.
Let's start with cooked food. After tomatoes, lycopene and carotene are cooked with oil, the absorption rate will be greatly improved. Only a very small amount of oil is needed to completely absorb lycopene (about 1 spoon of coffee per meal). This is because after tomatoes are cooked, the cell walls of tomato cells are destroyed and lycopene can be released freely.
The raw food you care about is of course a very good choice. First of all, it contains very low energy, which is lower than most fruits. People who need to control their weight can eat it with confidence. In addition, even without lycopene, it has the same health value. For example, fragile vitamin C can be preserved intact. For patients with hypertension, eating two or three raw tomatoes can easily provide a lot of potassium and vitamin C, which helps to control blood pressure and prevent obesity.

Is it better to eat tomatoes raw or cooked? In fact, you don't have to worry too much about this problem. Friends who like raw tomatoes can, and friends who like cooked tomatoes can.

Tomato is a kind of physical food, which can be used as fruit and vegetable. It is rich in water and high in water-soluble vitamins, such as vitamin C, but these components are easy to volatilize and lose during preheating, so the natural advantage of eating raw tomatoes is that they can retain more water-soluble vitamins and antioxidant components in the original tomatoes. But it should be noted that raw tomatoes must be eaten with red cooked tomatoes. If it is green tomato, it not only contains more phytic acid tannic acid, which inhibits the absorption of nutrients, but also contains more solanine, which is a unique component of solanaceae plants. If you take too much, it may cause poisoning, so be sure to pay attention.
What about cooked tomatoes? Cooked tomatoes are naturally a good choice. There is a special ingredient "lycopene" in tomatoes. Lycopene is a strong antioxidant, which also helps to resist free radicals, delay aging and improve disease resistance. Some studies have found that lycopene is helpful to prevent prostate diseases, gastric cancer and intestinal cancer, and it is a potential anticancer component. Lycopene exists in the cell wall of tomato. If high temperature destroys dietary fiber and cell wall, it will overflow more easily and be fully absorbed by us, so the nutritional value of heated tomatoes is not low, just to absorb more nutrients. Weigh it first, don't heat it for too long, heat it properly.
There is little difference in nutrition between raw tomatoes and cooked tomatoes. You can eat whatever you like.
