Tomato contains not only protein, fat, carbohydrate and other nutrients, but also vitamins B1, B2, C, P and other vitamins and minerals such as potassium, calcium, phosphorus, iron. Tomatoes also contain lycopene, a nutrient with important physiological effects.
Lycopene has a unique antioxidant capacity, which can eliminate free radicals, inhibit mutations, reduce nucleic acid damage, and also prevent the process of cancer. It can be called the "gold" contained in tomatoes.
Choose a good move
Touch the fruit body
Tomatoes will become soft after ripening. If you feel that there are obviously hard core tomatoes inside, you'd better not buy them.
Look at the appearance
Mature tomatoes are bright red, and yellow varieties are bright yellow. It is better to choose the ones with uniform color; The shape of the tomato is natural. The tomato with "crooked melon and split date" may be sweeter, but if there are obvious protrusions on the fruit body, it is better not to choose. Don't buy tomatoes with uneven coloring and colorful faces, because they are fruits infected with tomato virus disease, with poor taste and nutrition.
Distinguish ripening fruit
Most of the ripened tomatoes are out of season. They are all red, hard to handle, not round in appearance, seedless or green in color, and less juicy in flesh; The naturally mature tomato stalks are surrounded by green, the fruit is smooth as a whole, the seeds are earthy yellow, the flesh is red, sandy and juicy.
Choose according to the way you eat
If you want to eat it raw, buy the pink one, because this tomato has a light sour taste and is better to eat it raw.
If you want to eat it cooked, it is better to buy big red tomatoes. Big tomatoes have a strong sour taste, which is good for frying or making soup.
Note: The cyan tomato contains a large amount of toxic lycopene, which will cause dizziness, nausea, vomiting, general fatigue and other toxic symptoms after eating.
Therefore, immature green tomatoes should not be eaten. Tomatoes contain a large amount of colloid, fruit and other ingredients, which are easy to react with gastric acid and coagulate into insoluble blocky substances, blocking the gastric outlet, causing stomach expansion and causing abdominal pain symptoms, so they should be eaten after meals.
