Did you know that lycopene in tomatoes can prevent cancer? Do you know which part of the tomato contains the highest amount of lycopene? Do you know how to eat to absorb more lycopene?

The tomato, also known as tomato, is a food that we often eat. Tomatoes are bright in color, sweet and sour in taste, and not very expensive. Because they are rich in vitamins and can be eaten raw, they are known as "fruit vegetables". In recent years, scientists have discovered that tomatoes contain a good thing, lycopene. This lycopene can prevent cancer

. So it seems that tomatoes are really a treasure of the whole body, both delicious and nutritious. So, since tomatoes are so good, how to eat to scientifically utilize its value?

Because lycopene can not be directly converted into vitamin A is used by people, therefore, for a long time only as a natural pigment and exist, until recent years, scientists have found that lycopene has a strong anti-cancer, anti-cancer effect, especially for prostate cancer.

Lycopene has many health benefits. Cooked tomatoes are easier to absorb lycopene than raw ones because, as lycopene is a fat-soluble substance, it is more easily absorbed by the body when heated with oil. Here, we also want to remind you to pay attention to, tomatoes should not be heated for too long, preferably not more than 30 minutes. If heated for too long, the lycopene in tomatoes will be broken down automatically. In addition, to get more lycopene. It is best to eat more processed tomato food.

The lycopene in tomatoes is very good for human health, so is it not eating tomatoes can be ingested lycopene? We usually eat tomatoes the most common way to eat raw, fried or soup, but these eating methods can not maximize the intake of lycopene. So, how else can we actually eat it? Let me tell you, that is to make tomato sauce and eat it, and of course, tomato salsa. They contain the highest amount of lycopene. Why? Because 5 tons of fresh tomatoes in order to process a ton of ketchup, barrels of ketchup above the weight of 198 grams, almost 4 two, in accordance with what we just said 1:5 ratio, that is to say, eat a bucket of ketchup, the equivalent of eating 2 pounds of fresh tomatoes.

At present, in the domestic market is mainly sold in the tomato sauce and tomato salsa, these two kinds of food, in the end, which one of the lycopene contained some higher?

The lycopene content of ketchup is higher than that of tomato salsa, due to the large amount of flavorings added to tomato salsa.

When we buy ketchup, it's best to choose ketchup from Xinjiang, which has long sunshine hours and a big temperature difference between day and night, and the tomatoes grown under such conditions have a particularly good color, which is particularly red. The redder the tomato, the higher the lycopene content. In addition, the dry climate of the Xinjiang region, tomatoes are not easy to grow mold, more suitable for tomato sauce.

According to statistics, the world's annual production of processed tomato products is more than 300 million tons, the United States accounted for this 1 / 3, and it is basically not for export, that is to say, in the United States, the processing of tomato-based food products are almost all eaten by the Americans themselves. In this way, the U.S. per capita annual consumption of processed tomato food more than 20 kilograms. However, in our country, due to dietary habits, people rarely eat ketchup, that is, in the cooking time, only the ketchup as a seasoning to put on a little. Now you know that ketchup has so many benefits, is not also ready to eat a little more ketchup?

When I told you about ketchup, is it the only way to get lycopene? In fact, there is a part of the tomato itself that is very rich in lycopene, and that is the tomato skin. However, when people eat tomatoes, they will always peel off the skin and not eat it, mainly because they think that the skin is not easy to be digested. So what can we do to get lycopene, but also to digest the tomato skin? In fact, the method is very simple, you just need to cut the tomato into very small pieces, almost the size of the thumb cap can be, so that not only can absorb lycopene, but also can digest the tomato skin. In addition, to tell you a little, is the tomato skin on constipation there is a certain healing effect it!

Nutritionists believe that every day as long as the raw food 100-200 grams of fresh tomatoes, can ensure that the body needs vitamins and minerals, but raw food to pay attention to the following points:

1, should not be eaten unripe tomatoes. Unripe raw tomatoes contain lobelia alkaloids, eating will make the mouth bitter, stomach upset, eating more can lead to poisoning.

2, should not eat a lot of tomatoes on an empty stomach, because tomatoes contain more gelatinous, fructose, persimmon gum phenol and other ingredients, easy to combine with the stomach acid to generate a block of stones, resulting in stomach distension.

3, suffering from acute gastroenteritis, acute bacillary dysentery patients should not eat tomatoes, so as not to aggravate the condition.

4, can not eat rotten tomatoes, in order to prevent poisoning

Scientific studies have also found that, compared with the consumption of raw tomatoes, people consume processed tomatoes, more to improve the concentration of antioxidants such as lycopene in the blood. This is because high temperatures destroy the cell walls of tomato cells, thereby increasing the release of antioxidants such as lycopene. In addition, tomatoes in the cooking process, often use peanut oil, salad oil and other vegetable oils, and these fats will help tomatoes will be lycopene and other fat-soluble antioxidants naturally released, to give full play to the role of antioxidants. Of course, there are advantages and disadvantages, after heating, tomatoes in the vitamin C will be lost, but tomatoes in the lycopene and other antioxidants in the content of a significant increase. Therefore, cooked tomatoes have a higher overall nutritional value than raw tomatoes. In addition, tomato skins contain large amounts of lycopene, so it is best not to discard the skins when eating them.

For patients with vitamin C deficiency, eating raw tomatoes is also a good way to supplement vitamin C. However, green tomatoes that are not yet ripe can be used for a variety of purposes. However, unripe green tomatoes contain toxins and should not be eaten. In addition, some of the tomatoes because of the use of plant hormones in the growth process and show the top of the protruding, this kind of tomatoes should not be eaten.

Tomatoes contain a certain amount of vitamins and dietary fiber, which is no different from other vegetables. But apart from vitamins, tomatoes also contain lycopene. Lycopene is a natural pigment that makes tomatoes red, and it works similarly to carotene in the body as a stronger antioxidant, which may have a preventive effect against cardiovascular disease and some cancers to some extent. It has been reported that men who eat a lot of tomatoes have a relatively lower risk of prostate cancer, which is related to the antioxidant component of lycopene in tomatoes.

Tomatoes PK ketchup

Concentrated ketchup contains higher levels of lycopene compared to tomatoes. However, ketchup loses the dietary fiber contained in fresh tomatoes. Therefore, experts say that you can eat both fresh tomatoes and ketchup, and it is best to consume some of both properly.

Raw PK cooked

Tomatoes can be eaten raw or cooked. These two ways of eating are good for the body, you can choose according to their own preferences. Experts, lycopene and carotene are soluble in fat, so fried tomatoes or make soup, etc. are very good, raw low absorption rate. If the intake of vitamin C, the raw and cooked can be, because the acidity of the tomato is large, conducive to the stabilization of vitamin C, cooking after the loss of relatively small. If you get potassium and dietary fiber, also raw and cooked can be.

Tomatoes are cold in nature and have the effect of clearing heat and cooling the blood and quenching thirst. If you are thirsty, eat a tomato, very comfortable. However, for people who are afraid of cold, cooked and eat is the best choice, raw food is easy to intolerance, leading to diarrhea
