1, overnight lemonade is not recommended.
Don't drink lemonade after night. After citric acid reacts with air, there will be sediment, which is not good for the stomach. In severe cases, it will lead to vomiting. Drinking lemonade overnight is actually harmless, but lemonade is easy to oxidize, so there are often water stains on the cups of lemonade overnight.
2. The efficacy of lemonade
Skin whitening
Because lemon is extremely rich in vitamins, lemonade is a good beauty product, which can prevent and eliminate skin pigmentation and play a whitening role.
Prevention and treatment of cardiovascular diseases
Drinking lemonade can also prevent and treat cardiovascular diseases, because lemonade can alleviate the role of calcium ions in promoting blood coagulation, so it can prevent and assist in the treatment of hypertension and myocardial infarction;
Prevention and treatment in kidney calculi
Lemon water contains a lot of citrate, which can inhibit the crystallization of calcium salt, thus preventing the formation of kidney calculi, and even reducing the number of stones in some patients with chronic kidney calculi.
improve immunity
Lemon is rich in vitamin C, which has many functions, such as anti-bacteria, improving immunity and assisting the formation of bone collagen. Drinking lemonade often can supplement vitamin C.
Little known is that lemon can also expectorate, and the expectorant effect is stronger than orange and citrus. Add warm water and salt to lemon juice, drink it and cough up the thick phlegm accumulated in your throat. At the beginning of a cold, you may wish to wash it with lemon and honey, which can relieve sore throat and reduce discomfort such as dry throat.
Promote wound healing
Vitamin C is one of the important nutrients to promote wound healing and keep bones, tissues and cartilage healthy. Vitamin c also helps to neutralize free radicals and inhibit inflammation in the body.
Anti-skin aging
The antioxidant effect of lemonade is helpful to deal with free radical damage in the body and alleviate the aging process. Its rich vitamin C can help amino acids synthesize collagen, protect the skin and prevent premature wrinkles.
Reduce appetite
Lemonade contains soluble cellulose pectin, which helps to enhance satiety, thus controlling appetite and preventing overeating. Keeping full for a long time also helps to eat less snacks, thus controlling weight.
Help digestion
Lemonade is beneficial to the health of digestive tract, can stimulate the secretion of gastric juice, help digestion, promote defecation and clean intestines. Lemonade can also relieve symptoms such as indigestion, heartburn and flatulence.
Purify urethra
Lemonade has diuretic effect. Drinking lemonade helps the body excrete toxins faster, thus purifying the body and keeping healthy. Lemonade also helps to change the pH value of urethra and prevent the growth of harmful bacteria.
Reduce urine acidity
Although there is citric acid in lemon water, potassium and calcium ions in it can combine with acid radical ions, which can reduce the acidity of urine and be beneficial to health. It is a typical alkaline food.
Fresh breath
Lemonade has a bactericidal effect, especially killing harmful bacteria in the mouth, thus keeping the breath fresh. A glass of lemonade for breakfast is more refreshing than coffee. It is suggested that lemonade should not be chilled, and room temperature is the best.
Improve blood circulation

Help detoxify the liver.
Purify the liver by promoting bile secretion. Lemonade also helps to control excess bile, reduce mucus production in the body and help dissolve gallstones. Lemonade is alkaline.
Firstly, it is clear that lemon juice is acidic. However, the acidity and alkalinity of food is not divided by its apparent ph value, but by the effect of human digestion and absorption: foods with a large proportion of salt (usually rich in sodium and potassium), such as various fruits and vegetables, are called alkaline foods after metabolism, and are also acidic foods, such as tofu and meat.
3. Side effects of lemonade
Citric acid in lemon can prevent and eliminate skin pigmentation and has moisturizing effect. At the same time, it can whiten skin, prevent computer radiation, lose weight, eliminate constipation and prevent aging. Although bee lemon is good, it is not suitable for people with stomach cold and qi stagnation, which leads to abdominal distension, discomfort and poor breathing caused by deficiency cold and phlegm. For people with cold, cough and fever, it is not advisable to eat too much lemon products.
Honey is a natural nutrient, which has the functions of clearing away heat and toxic materials and moistening dryness. If lemon juice and honey are mixed with warm water to make honey lemonade, it is a perfect nutritional combination. At the beginning of a cold, drinking honey lemonade can also relieve sore throat and relieve discomfort such as dry throat.
For computer families, drinking this water often can dilute the facial spots caused by computer radiation. It is worth noting that people with hyperacidity and ulcers should not drink it.
4. The misunderstanding of drinking lemonade
1. No hot water.
Some people say that lemons can't be soaked in hot water for fear of vitamin C loss. In fact, the water for soaking lemons should not be too cold, otherwise the fragrance will not come out. Because lemon is very acidic, vitamin C has good heat resistance under acidic conditions and is not as easy to lose as expected. There is no problem that the water temperature of lemon slices is higher than 60 degrees. Besides, drinking lemonade is not just for a little vitamin C. As the temperature rises, the food will be more sour, so hot lemonade will be more sour. The solution to this problem is simple. Let the lemonade cool a little before drinking.
2. You can't drink stomach trouble
Some people say that people with stomach problems can't drink lemonade, because too strong acidity will stimulate the stomach and intestines, and excessive stomach acid is even more unavailable. But in fact, using a slice of lemon to soak a large bottle of water, the taste of lemonade is very weak, not as sour as sweet drinks such as cola, and it will not cause gastric ulcer. It's not like drinking pure lemon juice (the pH value of pure lemon juice is around pH2.5, which is equivalent to cola). Because citric acid is beneficial to the absorption of many minerals, westerners like to squeeze lemon juice on fish, meat and eggs, thinking that it can help digestion. For people with indigestion, adding a thin slice of ginger to lemon water and drinking it at meals will help promote the secretion of digestive juice.
Make it strong
Lemon soaked in water must be light, and a lemon soaked in water with skin can pour 3 ~ 4 cups. This lemonade has no strong sour taste and can be drunk without sugar or honey, so it contains less energy. Lemon must be peeled and sliced, because the peel contains more flavonoids, which may be more worthy of soaking than lemon pulp. Lemon essential oil is mainly in the peel, and the aroma components in the lemon peel are easily soaked out when sliced. Lemon peel, including other citrus peels, contains some bitter flavonoids, such as hesperidin and naringin, but they are also beneficial components. A little bitter, with sour taste, it will make you thirsty in hot weather.
Don't drink lemonade during the day.
Some people have heard that lemonade can whiten skin, but others have heard that lemonade is a kind of "photosensitive food", and they are worried that drinking lemonade during the day will darken the skin. However, this statement is limited to online rumors, and no relevant research evidence has been seen. There is even information on the Internet that vitamin C is a photosensitive substance. If so, all fruits and vegetables contain vitamin C. It seems that people can't eat any fruits and vegetables during the day-obviously it's ridiculous.
5. It will promote stones.
Some people say that lemonade can't be eaten with foods rich in calcium. Calcium and citric acid will combine to form a precipitate, and even form stones in the body. This is a rumor. Calcium citrate is slightly soluble in water, and the solubility of calcium citrate tetrahydrate is 0.02g/ 100g water, which seems not high, but calcium citrate is a good material for making calcium supplement products, because it can be absorbed by human body without the help of gastric acid. In fact, citric acid does not promote the formation of kidney calculi as oxalic acid does. On the contrary, organic acids such as citric acid are beneficial to the absorption of minerals such as calcium, magnesium, iron and zinc in food. Studies have proved that citric acid is also beneficial to the prevention of kidney calculi, and it is even used for the treatment of kidney calculi.
