1, drink lemon water misconceptions

(1) soak a thicker point of good

Lemon soak must be light, a piece of lemon with the skin of the lemon soak a zhang of water, can be poured into the 3 to 4 cups. Such lemonade does not have a very strong sour flavor, no sugar or honey can drink, so that contains less energy. Lemon must be with the skin, the slice must be thin, because the skin part of the flavonoids higher, may be more worthwhile than the lemon pulp, lemon essential oils are also mainly in the skin inside, thinly sliced lemon peel in the aroma of the ingredients easy to soak out. Lemon peels, including other citrus peels, contain some bitter flavonoids, such as hesperidin and naringin, but they are also beneficial. There's a slight bitterness that works with the acidity to make it more thirst-quenching when you drink it in the heat of the day.

(2) can not use hot water

Some people say that lemons can not be soaked in hot water, for fear of vitamin C loss. In fact, the water to soak lemons can not be too cold, otherwise the flavor can not soak out. Due to the strong acidity of lemon, vitamin C in acidic conditions of heat resistance is better, not so easy to imagine the loss, soak lemon slices of water temperature higher than 60 degrees is perfectly fine. Besides, you don't drink lemonade just for the vitamin C. The acidic flavor of the food is a little stronger at higher temperatures, so hot lemonade will also seem more acidic. It's easy to fix this, just let the lemonade cool slightly before drinking it.

(3) will promote stones

Some people say that lemonade can not be eaten with calcium-rich foods, calcium and citric acid will be combined to form a precipitate, and even in the body to generate stones, which can be a rumor. Calcium citrate is slightly soluble in water, I checked, the solubility of calcium citrate tetrahydrate is 0.02 grams / 100 grams of water, it seems not high, but calcium citrate is a good material to make calcium supplement products, because it does not need the help of stomach acid can be absorbed by the body. In fact, citric acid will not promote kidney stones like oxalic acid, on the contrary, citric acid and other organic acids are beneficial to the absorption of calcium, magnesium, iron, zinc and other minerals in the food, and research has proved that citric acid is also beneficial to the prevention of kidney stones, and has even been used in the treatment of kidney stones. Lemon can not eat with what

(4) stomach disease can not drink

Some people say that people with stomach disease can not drink lemonade, because the acidity will be too strong to stimulate the stomach, the stomach acid is too much more than can not be used. But in fact with a slice of lemon to soak a large bottle of water, soak out of the lemonade flavor is very light, not at all as acidic as sweet drinks such as Coke, and not so much as to cause stomach ulcers. It's not like you're drinking pure lemon juice (pure lemon juice is about pH 2.5, comparable to Coke). Since citric acid facilitates the absorption of many minerals, Westerners like to squeeze lemon juice on fish, meat, and eggs as an aid to digestion. For those who suffer from indigestion, adding a thin slice of ginger to lemonade and drinking it with meals will be beneficial in promoting the secretion of digestive juices.

(5) can not drink during the day

Some people have heard that lemon water can whiten, but some people have heard that the lemon is a "light-sensitive food", and are worried that after drinking lemon water in the daytime, the skin will be spotty and dark. But this claim is limited to online rumors, have not seen the relevant research evidence. There is even online information that vitamin C is a photosensitive substance, if this is the case, all fruits and vegetables contain vitamin C, it seems that people can not eat any fruits and vegetables during the day - obviously very ridiculous. From a scientific point of view, the main photosensitive substances in food include chlorophyll, riboflavin, hemoglobin. To say that eating photosensitive substances to grow spots, probably the first red meat can not be eaten (hemoglobin more), dairy can not be eaten (more riboflavin), leafy greens and kiwi can not be eaten (with chlorophyll), it seems that during the day can only eat food!

(6) lemon is acidic

Because of the "acidic foods lead to acidic body" said deep in people's hearts, lemonade is acidic food or alkaline food, has been letting a lot of people very dizzy. Obviously drink is sour taste, pH value is also acidic, why there is alkaline food called? This is because although there is citric acid in lemons, citric acid can be completely metabolized in the body to generate carbon dioxide and water, with the carbon dioxide exhaled out of the body, the acidity will be eliminated. The potassium and calcium ions in lemons, however, remain in the body in the form of metal cations. These ions can be combined with acid ions, which can reduce the acidity of urine, so it is known as "alkalizing food". Not only lemons, but also most fruits are alkalizing foods. This is especially important for people with gout and hyperuricemia, because when urine is alkaline, uric acid forms salt, which is easier for the body to eliminate, reducing the risk of gout attacks. As for the term "acidic body," it's not very scientific, so it's best to forget about it.

2, lemon how to store

Some people ask, each time only use a piece of lemon, that the rest of how to do? In fact, do not worry too much. Lemon fruit storage is quite good, so when Dr. Linde will recommend that mariners carry lemons on board. The problem with storing lemons for a long time is that they dry out on the surface, but when they do, they are still usable and juicy on the inside for up to a month. A cut lemon with a little honey on the surface, wrapped in plastic wrap, and kept in a crisper for two or three days is not a problem. This is due to the acidity of lemons, most microorganisms tend to know what to do. Dried lemons can also be used to make water, but because the zest has lost its aroma and there is a loss of vitamin C, the flavor of the lemonade will be discounted, but it can still be used to make lemon tea, which will provide some citric acid and potassium. There is also a lemon preservation tips, will be washed lemon, insert a straw, squeeze the juice, remove the straw, in the hole covered with plastic wrap into the refrigerator, can be stored for 3 to 5 days.

3, will not get fat

Light lemonade is a good drink, which is very low in sugar (lemon sugar 0.5% or so, and added so much water dilution), contains negligible energy, so it will not make people fat. However, it's a different story when sugar or honey is added. Sour foods, with a little sugar, are always a special treat, and so is lemonade. Cold lemonade with a little honey will feel especially refreshing and thirst-quenching. However, lightly sweetened lemonade contains about 5% sugar, and both the fructose in honey and the sucrose in white sugar are just as energizing. By 5% sugar, a paper cup (200 grams) of sweetened honey water contains 40 kilocalories of energy, and if you drink two cups, it is equivalent to eating 1/4 bowl of rice, so people who control their weight still need to be limited, and can not because of the honey lemonade is good to drink daily booze.

Lemon water is still very good for our health, people with stomach problems can be appropriate to drink less, drink a little light lemon water or can not hurt the stomach, there is a certain promotion of the digestive effect, of course, want to lose weight friends can also try.

4, lemon taboo food

1, lemon and seafood should not be eaten together.

Seafood such as shrimp, crab, sea cucumbers, jellyfish and other seafood is very rich in protein and calcium and other nutrients, and lemon in the fruit acid content is more.

If you eat lemon and seafood at the same time, the fruit acids in the lemon will make the protein coagulate, and will also be combined with calcium to produce substances that are not easy to digest.

Not only does it reduce the nutritional value of the food, but it also causes gastrointestinal discomfort, so try to avoid eating lemon and seafood together.

Special attention should be paid to the lemon and shrimp with food is very dangerous. There is folklore that Thai cuisine in the famous dish "lemon shrimp" eaten will lead to poisoning, this is a certain truth.

Because the lemon in the vitamin C will make the shrimp contain metal - pentavalent arsenic into toxic arsenic, which is commonly known as the drug "arsenic".

2, lemon and milk should not be eaten together.

Similar to the case of seafood, similarly, milk is rich in protein and calcium, lemon and milk with food will affect the stomach, intestinal digestion.

Because the acid in lemon will combine with the alkaline substances in dairy products to form calcified substances in the body, which are stones. In addition, vitamin C-rich fruits are trying not to eat with dairy products ****.

3, lemon should not be eaten with carrots.

Because carrots contain ascorbic acid enzyme, eaten with lemon, will destroy the vitamin C in lemon, affecting the body's absorption.
