Will lemonade turn black during the day? What's wrong with lemonade?

Because lemonade has a fresh taste, it has always been known as' beauty drink '. Therefore, it is deeply loved by many people who love beauty, but many people have a great misunderstanding about lemonade, which is often false and very bad. Today, Xiaobian will take you to understand the mistakes about lemonade?

Lemon water is rich in vitamin C, and vitamin C is a strong reducing agent, which can reduce cytochrome c, cytochrome oxidase and molecular oxygen, achieve the effect of whitening and freckle removal, and also can remove free radicals in the body, delay aging. Therefore, drinking lemon water can play the role of beauty. But many people in drinking lemonade will appear the following errors.

Myth 1: some people are accustomed to using fresh lemon to squeeze out juice to make water and discard the lemon peel. However, the lemon peel is also very worthy of brewing, because the bioflavonoids contained in the peel are higher than the pulp, which can eliminate free radicals, have the function of antioxidation, regulate human immunity, prevent hypertension and cardiovascular diseases. In addition, lemon peel also contains a large amount of lemon essential oil, which can play a role in refreshing and eliminating burnout.

Myth 2: some people say that lemon can't be soaked in hot water, because too high water temperature will cause a large loss of vitamin C. In fact, the temperature of lemon water should not be too low, or the taste will not come out. Moreover, because lemon contains a lot of organic acids, and vitamin C has good heat resistance under acidic conditions, which is not easy to be damaged, so the water temperature of lemon brewing at about 60 ℃ is no problem.

Myth 3: there was a time when the idea that acidic constitution is easy to get cancer was very popular, and lemon was once regarded as an "acid food" because of its obvious sour taste, which made many people panic and wonder whether the lemonade with beauty effect can continue to drink. In fact, the sour taste of lemon mainly comes from citric acid, and citric acid can be completely metabolized into carbon dioxide and water in the body. Carbon dioxide in the blood is discharged from the body through respiration, and the acidity will naturally disappear, so lemon water is not an "acid food", which can be safely drunk.

Myth 4: some people say that they can't drink lemonade when they eat calcium rich foods, because the citric acid in lemonade will combine with calcium to form precipitation, or even stones in the body. In fact, citrate in lemon juice can inhibit calcium salt crystallization, thus preventing the formation of kidney stones, and even the stones that have been formed can be dissolved. Therefore, drinking lemon water does not lead to kidney stones. On the contrary, regular drinking lemon water can also prevent the occurrence of kidney stones to a certain extent.

Myth 5: I often hear from many female friends that lemonade can't be drunk in the daytime, because lemonade is a kind of photosensitive fruit. After drinking lemonade in the daytime, the skin will turn black. In fact, from a scientific point of view, light-sensitive substances mainly include chlorophyll, riboflavin and heme, which are widely found in people's food. If people eat light-sensitive substances, they will grow spots, so people have no food to eat during the day, which is obviously absurd. Moreover, the organic acids in lemon water will corrode the tooth surface and damage the enamel. If you drink a lot of lemon water at night and do not clean your teeth in time, it will easily lead to caries.
