Most of the reasons why you can't eat the same thing are like this: cucumbers contain a vitamin C enzyme that destroys vitamin C in other vegetables and fruits, and tomatoes are rich in vitamin C. When you eat them together, the vitamin C enzyme in the cucumber will destroy the vitamin C in the tomato, leading to a loss of nutrients.
It can be said that the person who made such a claim belongs to the typical only know one, do not know the other!
First of all, the cucumber seed itself contains a certain amount of vitamin C (per 100 grams of vitamin Vc 9 mg), but also contains a certain amount of vitamin C decomposition enzyme, these two substances are usually stored in different parts of the cell, do not see each other. And when we eat cucumber, food through the broken, part of the cell rupture, part of the vitamin C decomposition enzyme and vitamin C will meet, vitamin C will lose some.
That is to say, cucumbers eaten alone will also lose a small portion of vitamin C. In addition, unless the cucumber before eating into the juice, which will release all the vitamin C enzyme, and our ordinary chopping and chewing can only release a portion of vitamin C enzyme, the effect on vitamin C is very limited.
Secondly, all enzymes are proteins structurally speaking, and they are a special class of proteins in terms of structure and function. After these enzymes enter our stomach, they will be denatured and inactivated when they encounter highly acidic gastric acid, and their original function will be lost. Therefore, the vitamin C enzyme only works before the food enters the stomach, the most important thing is to cut vegetables and chewing period, so the vitamin C enzyme plays a role in the time is limited, the decomposition of vitamin C is not as serious as we think.
Once again, many people think that tomatoes in the vitamin C content is very rich, in fact, in vegetables and fruits, can only be regarded as a medium level, 100 grams of vitamin C 19 mg, and ordinary green leafy vegetables, fresh dates, kiwi, green peppers and other food vitamin C content is much higher than tomatoes, according to the argument of this phobia, the cucumber should not be even more with these high Vc content of leafy vegetables, fresh dates, kiwi, green peppers and so on. , fresh dates, kiwi and other foods eaten together.
In fact, vitamin C is a relatively sensitive nutrient, and it is impossible for 100 percent of the vitamin C in food to be retained and absorbed by us, so the concern that the vitamin C-degrading enzyme in cucumbers breaks down the vitamin C in tomatoes is completely unnecessary.
Since fresh fruits and vegetables contain a certain amount of vitamin C, instead of worrying about this loss of vitamin C in cucumbers and tomatoes, we should eat more fresh fruits and vegetables to improve our Vc intake.
