What kind of food is nutritious when eaten raw and cooked? Tomatoes are rich in natural antioxidants, besides vitamin C, there are lycopene. Everyone is familiar with vitamin C, which can prevent colds and treat scurvy. What about lycopene? This is a natural pigment that turns tomatoes red. It's like carotene to us. It is a strong antioxidant, which has the functions of anti-oxidative damage and protecting vascular endothelium. The higher the lycopene content in our plasma, the lower the incidence of coronary heart disease. Lycopene also plays an anti-cancer role. Friends with higher lycopene content in serum will have lower chances of developing gastric cancer and digestive tract cancer.
If you cook tomatoes before eating them, you will be able to increase the concentration of lycopene in your blood. This is because high temperature will destroy the cell wall of tomato cells and increase the release of lycopene. In addition, if peanut oil and salad oil are used in cooking, it will also contribute to the release of lycopene and give full play to its antioxidant effect. So tomatoes are more nutritious when cooked? Every coin has its two sides. If heated, vitamin C in tomatoes will be lost, but the overall nutritional value of cooked tomatoes is higher than that of raw tomatoes. Also, some friends like to blanch the tomatoes first, so that the skins can be easily removed. Is this for hygiene and better taste? I don't know much, but the skin of tomato contains a lot of lycopene, so it's best not to peel it when eating, and wash it more. If you lack vitamin C, you'd better eat it raw, which is a good way to supplement vitamin C, but the immature green tomato is poisonous, so don't eat it.
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.
