Eating lemons often can whiten the skin. What do you think of this?

The weather is getting hotter and hotter, and lemonade is considered to be a must-have drink for many people in summer. It is not only cool and thirst-quenching, but also rich in vitamins. Lemonade is also made of lemons. Speaking of lemons, everyone is familiar with them. It is very common in fruit shops, especially female friends, who have always said that eating lemons can lose weight and turn white. But some people say that eating lemons and drinking lemonade will turn black during the day. Are these ideas marketing tools or effective? Often eat lemon, what will happen to your body? Let's have a look. Lemon is rich in vitamin C and has good antioxidant activity. To some extent, it can dilute the melanin on the skin surface, thus achieving the whitening effect.

It is precisely because of this antioxidant effect that many skin care products contain vitamin C, and lemon also contains a lot of citric acid, which can promote the peristalsis of the stomach and accelerate the absorption and digestion of food, so that oil will not accumulate in the body, and the metabolism will be fast, and the toxins and fats in the body will be reduced, and the stomach will naturally flatten out. Generally speaking, lemon helps to lose weight and whiten skin. But it is also possible, provided that the diet is correct. Have you eaten lemons for so long? The water temperature of lemonade should not be too cold or too hot-generally speaking, the water temperature is about 60-70 degrees. If the water temperature is too cold, the fragrance of lemon will disappear; If the water is too hot, it will taste bitter.

In addition, the lemon soaked in water should be light, not sour or astringent, because a small amount of citric acid is beneficial to the repair of gastric mucosa, but too much acid may stimulate the stomach and damage the gastric mucosa. People who want to lose weight and lemonade are advised not to add sugar, but to soak lightly. Sugar-free lemonade contains no sodium, too much sugar, and the weight loss effect will be better. It is best to choose fresh lemons-fresh lemons are rich in flavor and nutrition, while dried lemons will lose a lot of aroma and vitamin C. After washing the lemon, it is also recommended to slice the skin. There are flavonoids in the skin, such as hesperidin, which is very healthy. Lemon essential oil is mainly in the skin. Flavonoids have a single bitter taste, and combined with the sour taste of lemon itself, they have a good effect of quenching thirst and reducing fever.

It is said that drinking lemon will turn black, mainly because lemon contains furan coumarin, limonene and other photosensitive substances. Some people with special physique may have certain photosensitive reactions after being irradiated by red and ultraviolet rays, causing skin allergies, pigmentation and blackening. But drinking lemon water will turn black during the day, which is not absolute. In fact, most of these factors are needed. For example, people with the above-mentioned special constitution, abnormal endocrine system or immune system may cause solar dermatitis if they eat too much lemon; And generally speaking, blackening is only possible after consuming a large number of photosensitive elements. In daily life, we make no more than three cups of lemonade at most, so the possibility of blackening is very small.
