About Lemonade 1: What's Better?
Lemon soaked in water must be light, a skin of lemon with a bar of water, can pour 3 to 4 cups. This kind of lemonade is not very sour, it can be drunk without sugar or honey, and it contains less energy. The lemon must be skinned, the slice must be thin, because the part of the skin contains higher flavonoids, which may be more worthwhile than the lemon pulp. The lemon essential oil is also mainly in the skin, and the aroma components in the lemon peel are easily soaked out.
Lemon peel, including other citrus peels, contains some bitter flavonoids, such as hesperidin and pomelo peel, but they are also beneficial ingredients. There is a bit of bitterness, and with the sour taste, the feeling of thirst quenches after a hot day of drinking.
About lemonade 2: Can't use hot water?
Some people say that lemon cannot be soaked in hot water and that vitamin C is lost. In fact, the lemon water cannot be too cold, otherwise the scent bubbles will not come out. Due to the strong acidity of the lemon, vitamin C is better heat-resistant under acidic conditions and is less easily lost than expected. The water temperature of the soaked lemon slices is higher than 60 degrees without any problems.
Besides, drinking lemonade is not just for vitamin C. As the temperature rises, the sourness of the food will be stronger, so hot lemonade will also appear more acidic. Solving this problem is as simple as letting the lemonade cool and drink.
About Lemonade 3: Will Promote Stones?
Some people say that lemonade cannot be eaten with calcium-rich foods. Calcium and citric acid combine to form precipitates and even generate stones in the body. This is a rumor. Calcium citrate is slightly soluble in water, and the solubility of calcium citrate tetrahydrate is 0.02 g/100 g water. It does not seem to be high, but calcium citrate is a good material for making calcium supplements because it does not require gastric acid to help. Absorbed by the body.
In fact, citric acid does not promote kidney stones like oxalic acid. On the contrary, organic acids such as citric acid are beneficial to the absorption of various minerals such as calcium, magnesium, iron, and zinc in foods. Studies have shown that citric acid affects kidney stones. Prevention is also beneficial and has even been used in the treatment of kidney stones.
About Lemonade 4: Stomach can't drink?
Some people say that people with stomach problems can't drink lemonade, because too much acid can irritate the stomach, and stomach acid can be excessively unusable. But actually using a slice of lemon to brew a large bottle of water, the scented lemonade tasted so light that it wasn't as acid as a sweet drink like cola, and it wouldn't cause stomach ulcers. Did not drink pure lemon juice (about pH2.5 pure lemon juice, and Coke quite).
Since citric acid is beneficial to the absorption of various minerals, Westerners like to squeeze lemon juice on fish, meat, and eggs, which they think can help digestion. For dyspeptics, adding a thin layer of ginger to lemonade and drinking it at the time of eating can be beneficial to the secretion of digestive juices.
About lemonade 5: Can't drink during the day?
Some people have heard that lemonade can be whitened, but others have heard that lemon is a kind of “photosensitive food†and they fear that the skin will become black after daytime drinking lemonade. However, this statement is limited to online uploading, and no relevant research evidence has yet been seen. There is even information on the Internet saying that vitamin C is a photosensitive material. If this is true, all fruits and vegetables contain vitamin C. It seems that people can't eat any fruits and vegetables during the day - it is obviously ridiculous.
From a scientific point of view, the main photosensitive substances in food include chlorophyll, riboflavin, and heme. To say that eating photosensitive substances on the long spot, probably first of all red meat can not eat (hemoglobin more), dairy can not eat (riboflavin and more), green leafy vegetables and kiwi can not eat (with chlorophyll), see Can only eat food during the day!
About lemonade 6: Lemon is acidic?
Because the phrase “acidic foods cause acidic constitutions†is deeply rooted in people’s minds, lemonade is acidic foods or alkaline foods, which has caused many people to dizzy. It is obviously sour after drinking, and the pH is also acidic. Why is there an alkaline food?
Because there is citric acid in lemons, citric acid can be completely metabolized in the body to produce carbon dioxide and water. As carbon dioxide exhales, the acidity is eliminated. The potassium and calcium ions in lemons stay in the body as metal cations. These ions can be combined with the acid ions, can reduce the acidity of urine, it is called "alkaline foods."
Not only lemons but most fruits are alkaline foods. This is especially important for patients with gout and hyperuricemia, because when the urine is alkaline, uric acid forms salts that are more easily eliminated by the body and can reduce the risk of gout attacks. As for the term "acidic constitution", it is not scientific in itself, or it is forgotten.
How about lemonade 7: lemon?
Someone asked, if only one slice of lemon was used each time, what would the rest be? The storage of lemon fruit is quite good, so the doctor will recommend that the seafarer carry the lemon on board. The problem with long-lasting lemons is that the surface is dry, but it can still be used after it is dried, the interior is still juicy, and there is no problem if it is left for a month. The cut lemon is coated with a little honey, wrapped in plastic wrap and put in the crisper for two or three days without problem. This is due to the large degree of citric acid, most of the microorganisms often retreat.
Dried lemon can also be used to soak water, but because the aroma of the skin has been lost, there is also a loss of vitamin C. The lemonade aroma will not be a small discount, but it can still be used to make lemon tea. It can provide some citric and potassium elements. . There is also a lemon preservation tips, wash the lemon, insert a straw, squeeze juice, remove the straw, cover the hole in the cling film into the refrigerator, can save 3 to 5 days.

Pale lemonade is a good drink, in which sugar is extremely low (about 0.5% sugar in lemon, plus so much water dilution), the energy contained is negligible, so it will not make people gain weight. However, after adding sugar or honey, it is different. Sour foods, accompanied by a bit of sugar, are always fascinating, and lemonade is the same. Cold lemonade adds a bit of honey and it feels particularly refreshing and thirsty.
However, the light sweet lemonade contains about 5% of sugar. Both fructose in honey and sucrose in white sugar will bring energy. According to 5% of the sugar, a cup (200 grams) of sugary honey water contains 40 kcal, if you drink two cups, it is equivalent to eating 1/4 bowl of rice, so people who need to control their weight still need to be limited. Drink booze daily because honey lemonade tastes good.
