First, the efficacy of freshly squeezed lemon juice
1. Runfei
Smokers need to eat more lemons because they need twice as much vitamin C as non-smokers. Also, people who live in smoggy weather or are exposed to second-hand smoke all the year round need to eat lemons. Hot lemon juice and honey are very effective in treating bronchitis and nasopharyngitis, and can moisten the lungs with Gandhi.
slim
Citric acid, which is rich in lemon, is an important compound in the process of transforming fat, protein and sugar into carbon dioxide. Citric acid inhibits fat accumulation. When we ingest citric acid, the sugar and lipid we ingest from food can be quickly converted into energy to avoid unnecessary accumulation. The fresh fragrance avoids stressful eating. When the mood is high or fluctuating, it is easy to produce stress, which can be relieved by eating. The natural fresh fragrance of lemon can help you calm down, relieve your mood and prevent false appetite.
3. Infiltrate blood vessels
People who often socialize need to eat more lemons. Lemon can strengthen stomach, relieve alcoholism, regulate vascular permeability, prevent cardiovascular arteriosclerosis and reduce blood viscosity.
4. Fresh breath
Gargling with lemonade can effectively kill bacteria in the mouth, and lemonade can also keep your breath fresh for a long time. Rinse your mouth with water within a few minutes after cleaning it with lemonade, because too strong acidity can also hurt your teeth.
Second, the misunderstanding of drinking lemon juice
1, is it better to make it thicker?
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.
2. Can't you use 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.
3. Will you 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. I checked, the solubility of calcium citrate tetrahydrate is 0.02g/ 100g water, which seems to be low, 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.
4, stomach trouble can not drink?
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.
5. Can't you drink 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. Scientifically speaking, the main photosensitive substances in food are chlorophyll, riboflavin and heme. If you eat photosensitive substances, you will get spots. Probably, first of all, you can't eat red meat (rich in heme), milk (rich in riboflavin), green leafy vegetables and kiwifruit (chlorophyll). It seems that we can only eat vegetables during the day!
