However, modern pharmacological studies have also found that the alkali contained in immature tomatoes is easy to cause poisoning if it is absorbed into the human body in a large amount in a short time. Its symptoms: nausea, vomiting, dizziness, salivation and general fever, and even life-threatening in severe cases. Therefore, immature tomatoes should not be eaten raw, even cooked food should be burned thoroughly. If vinegar is added in the cooking process, it can destroy lycopene and avoid poisoning.

Eat tomatoes scientifically
Do you know that lycopene in tomatoes can prevent cancer? Do you know which part of tomatoes has the highest lycopene content? Do you know how to eat to absorb more lycopene?
Tomatoes, also called tomatoes, are foods that we can often eat. Tomatoes are bright in color, sweet and sour in taste and not very expensive. Because it is rich in vitamins, it can be eaten raw and is known as "fruits and vegetables". In recent years, scientists have found that tomatoes also contain a good thing, that is, lycopene. This lycopene can prevent cancer.
Yes From this perspective, tomatoes are really full of treasures, both delicious and nutritious. So, since tomatoes are so good, how can we eat them to make scientific use of their value?
Because lycopene can't be directly converted into vitamin A and used by people, it just exists as a natural pigment for a long time. Until recent years, scientists found that lycopene has a strong anti-cancer effect, especially for prostate cancer.
Lycopene has many benefits to human health. Mature tomatoes absorb lycopene more easily than raw tomatoes, because lycopene is a fat-soluble substance, which is more easily absorbed by the human body after being heated by oil. Here, we also remind you that the heating time of tomatoes should not be too long, and it is best not to exceed 30 minutes. Because the heating time is too long, lycopene in tomatoes will decompose automatically. In addition, if you want to eat more lycopene. It is best to eat more processed tomato food.
Lycopene in tomatoes is very beneficial to human health. So, can you get lycopene after eating tomatoes? The most common ways to eat tomatoes are raw, stir-fried or soup, but none of these ways can maximize the intake of lycopene. So, what else can we eat? I'm telling you, that's tomato sauce. Of course, tomato sauce has the highest lycopene content. Why do you say that? Because only 5 tons of fresh tomatoes can be processed into one ton of ketchup, the weight marked on the ketchup bucket is 198 grams, which is almost 4 Liang. According to the ratio of 1: 5 we just said, that is to say, eating a bucket of tomato sauce is equivalent to eating 2 Jin of fresh tomatoes.
At present, the domestic market mainly sells ketchup and ketchup. Which of these two foods contains more lycopene?
The lycopene content in tomato sauce is higher than that in tomato sauce, which is caused by adding a lot of seasonings to tomato sauce.
When we buy ketchup, we'd better choose ketchup made in Xinjiang. This is because Xinjiang has a long sunshine time and a large temperature difference between day and night. The tomatoes grown under this condition are particularly good in color, that is, especially red. The redder the tomato color, the higher the lycopene content. In addition, the climate in Xinjiang is dry, and tomatoes are not easy to grow mildew, which is more suitable for ketchup.
According to statistics, the annual output of processed tomato products in the world is more than 3 million tons, of which the United States accounts for13, and it is basically not used for export, which means that almost all tomato foods processed in the United States are eaten by Americans themselves. In this way, the average American consumes more than 20 kilograms of processed tomato food every year. But in our country, people seldom eat ketchup because of their eating habits, that is, they put a little ketchup as seasoning when cooking. Since we know that ketchup has so many benefits, should we eat more ketchup?
I said so much tomato sauce just now, so, is it necessary to eat tomato sauce and absorb lycopene? In fact, a part of tomato itself is very rich in lycopene, that is, tomato skin. However, when people generally eat tomatoes, they always peel them and don't eat them, mainly because they think the skin of tomatoes is not easy to digest. Is there any way for us to absorb lycopene and digest tomato skin? In fact, the method is very simple. You just need to cut the tomato into small pieces, about the size of the little finger skull, so that you can not only absorb lycopene, but also digest the tomato skin. In addition, I want to tell you that tomato skin has a certain effect on constipation!
How to eat cucumbers?
As far as cucumber is concerned, it is a delicious and nutritious vegetable. In taste, cucumber meat is crisp and tender, with sweet juice and delicious fragrance. In terms of nutrition, it contains protein, fat, sugar, vitamins, cellulose and rich ingredients such as calcium, phosphorus, iron, potassium, sodium and magnesium. In particular, the micro-cellulose contained in cucumber can reduce the contents of cholesterol and triglyceride in blood, promote intestinal peristalsis, accelerate waste excretion and improve human metabolism. Propionic acid contained in fresh cucumber can also effectively inhibit the conversion of sugar into fat. Therefore, eating cucumber regularly can reduce weight and prevent coronary heart disease.
Why is it best not to have cucumbers for a "bumper harvest"? Because cucumber contains a vitamin C decomposing enzyme, it will destroy vitamin C rich in other vegetables. Tomatoes in the "bumper harvest" are typical vegetables rich in vitamin C. If we eat them together, the vitamin C we take from tomatoes will be destroyed by the decomposing enzymes in cucumbers, and the nutritional supplement effect will not be achieved at all.
In summer, in addition to a "bumper harvest", people often see people eating a cucumber and then a tomato; Or there is already a plate of "scrambled eggs with tomatoes" on the dining table, and then a plate of "fried meat with cucumbers". None of these ways are correct. In addition, the more vitamin C content in food, the more serious it is destroyed by the decomposing enzymes in cucumber.
Pepper, cauliflower, kale, bitter gourd and other vegetables also contain more vitamin C. It is best not to eat them with cucumbers.
As we all know, vitamin C is indispensable to human body, which can enhance resistance, prevent scurvy and resist infection. If vitamin C is seriously deficient, it may lead to symptoms such as gums, subcutaneous bleeding, nosebleeds and menorrhagia. An important way for us to get vitamin C in our life is to eat vegetables and fruits. Therefore, on the one hand, we should eat more fruits and vegetables and consume a lot of vitamin C; On the other hand, it should be eaten with cucumber as little as possible to preserve its nutritional value.
