Is it better to eat vitamin A or carotene

It's all good, it's good to eat, and I still care about this. Stupid and contemptuous of me.

It's good to supplement with some nutrients high calcium.

It is best to eat fresh fruits and vegetables.

Feasible, there is nothing bad about nutritional supplements, but as our nutritionists, it is still recommended to take vitamin A in food, vitamin A is a fat-soluble protein, and it cannot be fully absorbed if taken alone without the participation of oil, for example, carrots are almost only 15-20% of carotene ingested without frying in oil, and 70-80% can be absorbed by frying in oil. If you take tablets, you need to eat close to the time you eat so that you can use the fat of the dish to digest and absorb vitamin A. At present, the vitamins of tablets are also different from plants and from animals, animals generally come from deep-sea fish, which are more expensive, and plants come from dark-colored vegetables and fruits, which are cheaper.

Which is better depends on the vitamin A content written on the bottle.

Vitamin A is a fat-soluble vitamin, that is to say, it needs oil to digest and absorb the vitamin, because your cholecystitis needs to be avoided, so it is easier to be deficient, as well as vitamin E, and some vitamin B are easy to be deficient, so I recommend that you take a whole vitamin after meals.

To fight inflammation, the best nutrition is protein, which strengthens your immunity, but cholecystitis should be avoided, it is recommended that you eat less meat and more beans, and a mixture of grains and beans is equivalent to lean meat. Vitamin C to reduce your inflammation, Vitamin A to protect your cells, and Vitamin E to prevent your cells from mutating.

And the reason why you are not recommended to use drugs alone is that your cholecystitis needs to drink a lot of water, reduce constipation, and let the bile be excreted smoothly. Excessive amounts of vitamin A can cause poisoning, and the dose is at 15,000ug (49,500IU), giving you two different unit options, if you must take it, watch the dosage on the bottle and don't overdose.

- Carotene is good.

Carotene is absorbed in the small intestine of the human body and requires -carotene in the body15, 15'- oxygenase and - carotene 9', 10'- Dipoxygenase cleaves -carotene to produce the active form of vitamin A.

Digression: Carnivores do not have these two enzymes, because carnivores get vitamin A directly from meat, so cats will not be poisoned with vitamin A if they eat too many carrots, but cats will not be willing to eat a lot of carrots. ）

If you eat too much vitamin A, you will be poisoned, but if you eat too much carotene, you will have a yellow face and yellow hands at most.

In addition, -carotene can synthesize vitamin A, antioxidant, anti-inflammatory and immunomodulatory functions in addition to wide spine.

Therefore, I recommend you to supplement carotene well.

As a reminder, you can get a lot of yellow, yellow, orange and orange foods such as carrots, pumpkin, goji berries, spinach, mangoes, etc.

Many of the yellow and red pigments present in the plant body are carotenoids, mostly carotenoids, the most important of which is - carotene, which can be decomposed into vitamin A, but all carotenoids that can be decomposed into vitamin A are called provitamin A. Don't have the mistake of equating carotene with vitamin A!! It is more abundant in animal foods.

Vitamin A is only found in animals, and is found in a lot in fish, especially cod liver oil. Plants do not contain vitamin A, but many vegetables and fruits do contain provitamin A, carotene, which I mentioned above.

Functions of vitamin A:

1.Deficiencies in maintaining normal visual function (which is why it is often said to eat carrots to brighten the eyes) can lead to night blindness.

2.Maintain the health of epithelial tissue cells. Deficiency can lead to keratinization of the nasopharynx and other respiratory tract, gastrointestinal tract and even wild ulnar genitourinary endometriosis, weakening the natural barrier against bacterial invasion and susceptibility to infection.

Children are more likely to have respiratory infections and diarrhea. Some kidney stones are also associated with keratinization of the urinary tract. But if you eat as hard as you can, no matter how much you eat, your resistance to epithelial infection does not increase with the dose.

3.Maintain the normal growth and development of bones, promote growth and reproduction, so your mother forced you to eat carrots when you were a child. When vitamin A is deficient, the balance between osteoblasts and osteoclasts is disrupted, or the bone is overproliferated due to increased osteogenic activity, and the consequences of overproliferation are well understood.

Daily supplementation with carotene is good.

Because eating carotene food can supplement vitamin A, it not only has the efficacy and effect of vitamin A, but also has the benefits of promoting the healthy growth of bones and teeth, maintaining reproductive function, resisting free radicals, and enhancing immunity, which cannot be replaced by vitamin A.

However, the absorption of vitamin A is active absorption, and the absorption rate is 7-30 times faster than carotene, and the absorption of carotene is related to the intake, which is relatively slow.

Fat solubility refers to the ability of a substance to be dissolved in non-polar solvents (such as benzene, ether, carbon tetrachloride, petroleum ether, etc.). Fat-soluble substances usually have long carbon chains in their molecules.

For example: alkanes, fatty acids, fats, fats, etc.

Generally speaking, molecules contain organic matter with more than six carbon atoms, such as alcohols, aldehydes, ketones, acids, etc., which are often insoluble in water and fat-soluble.

Generally, charged particles have poor fat solubility.

The fat-solubility of substances can be explained by the principle of coarse compatibility, because solvents are generally non-polar organic substances, and the solutes that are easily dissolved in them are generally non-polar organic substances, while polar solutes and inorganic substances are generally poorly fat-soluble.

In living organisms, fat-soluble substances can cross cell membranes.

1 is not. Carotene is a hormone found in plants, which is found in dark vegetables and fruits in food; Vitamin A is an animal vitamin that exists in the animal body, also known as fat-soluble vitamins, the two are different, but the two have a certain connection, because the human body can be converted into vitamin A in the body by eating carotene in plants, so carotene is a source of vitamin A.

2 carotene exists in dark vegetables and fruits, such as common carrots, there are milligrams of carotene in 100 grams, when we eat carrots, these carotenes will be separated from protein complexes under the action of digestive enzymes in the gastrointestinal tract, and form chylomicrons after bile emulsification together with other esters in the duodenum, and then close to the brush edge of intestinal absorption cells in order to be absorbed by small intestinal mucosal epithelial cells, The absorbed carotene will be immediately transferred to one side of the cell in the small intestinal epithelial cells, and some of it will be cleaved by dioxygenase on ** or one side and converted into vitamin A to meet the needs of the body, and the other part will be transported to the liver and stored in extrahepatic tissues.

3. Daily supplementation of carotene is good.

Because eating carotene food can supplement vitamin A, it not only has the efficacy and effect of vitamin A, but also has the benefits of promoting the healthy growth of bones and teeth, maintaining reproductive function, resisting free radicals, and enhancing immunity, which cannot be replaced by vitamin A.

However, the absorption of vitamin A is active absorption, and the absorption rate is 7-30 times faster than carotene, and the absorption of carotene is related to the intake, which is relatively slow.

4. Generally, red, yellow, orange, and green leafy vegetables have a higher content of carotene, such as: carrots, pumpkin, tomatoes, persimmons, apricots, loquats, oranges, daylily, spinach, broccoli, etc., usually eat more of the above foods to supplement carotene, or oral carotene supplements under the guidance of a doctor, usually 1 time a day, 1-2 capsules at a time, with or after meals.

Carrots don't contain vitamin A, they contain vitamin C. It is still good to eat more carrots to supplement vitamin C.

Is Naivet Vita Vitamin A? Do you need to eat more carrots in Que Zhou Branch? Hu Lao does not contain mainly vitamin A. If you usually eat a lot of carrots, it is friendly to the eyes.

Is it vitamin A? Do you usually need to eat more carrots? Carrots are vitamin A, and eating more carrots is very good for the body.

What is the crux of the matter? Darwin once mentioned that a person who dares to waste even an hour of his time shows that he does not know how to value the full value of life. This seems to answer my doubts.

Every few people have to or are the first to face these problems. When faced with the problem of rotten people.

Vitamin A is a fat-soluble vitamin, vitamin A is stored in the animal body, and the plant body only contains carotene, but carotene can be converted into vitamin A in the human body

Carotene is not vitamin A, vitamin A is a kind of fat-soluble vitamin, vitamin A exists in the animal body, the plant body only contains carotene and carotene, but carotene can be converted into vitamin A in the human body, and the absorption process of vitamin A and carotene is different. ”

Many of the yellow and red carotenoids in the plant body are carotenoids, mostly carotenoids, the most important of which is carotene, which can be decomposed into vitamin A, but all carotenoids that can be decomposed into vitamin A.

The carotene contained in plant-based round foods can also be converted into vitamin A in the body, such as carrots, amaranth, spinach, leeks, and green peppers in vegetables, as well as oranges, apricots, and persimmons in fruits.

1 Not really.

Carotene is a hormone found in plants, which is found in dark vegetables and fruits in food; Vitamin A is an animal vitamin that exists in animals, also known as fat-soluble vitamins, and the two are different.

However, there is a certain relationship between the two, because carotene is the main source of vitamin A, and the carotene contained in the food we eat can be partially converted into vitamin A in the human body, so eating foods rich in carotene can also supplement vitamin A.

2. If you just want to supplement nutrition, it is recommended to choose carotene to be safer.

Carotene is much safer than vitamin A, because excessive consumption of vitamin A can lead to vitamin A toxicity, because vitamin A is soluble in fat but not in water. Carotene, on the other hand, can be dissolved in water to break down many of the body's required active ingredients, including vitamin A. In addition, carotene contains other nutrients in addition to vitamin A.

31.Carotene can increase the humidity of the eyes, help keep the cornea moisturized, and make the eyes clear and clear, which can promote eye health.

2.Carotene can be converted into vitamin A in the body, which is a component of retinal cells, which can promote the regeneration of rhodopsin and enhance vision.

3.Carotene prevents cataracts, protects the fibrous part of the eye lens, and prevents damage to the lens.

4.Vitamin A can prevent night blindness and enhance the ability of the eyes to distinguish colors.

4. If there is no lack of carotene, it is recommended not to eat it for a long time, but to eat it regularly. However, if the body is deficient in carotene or vitamin A, then it can be taken for a long time under the guidance of a doctor.

Generally, people who use computers for a long time, people with vision loss, people with poor vision such as glaucoma, presbyopia, cataracts, diabetes, etc., as well as people who are susceptible to respiratory infections and people with low immunity can take carotene.

In fact, many vegetables and fruits in life contain carotene, such as carrots, broccoli, sweet potatoes, mangoes, wolfberries, tomatoes, etc.

The main differences between carotene and vitamin A are as follows:

1. Vitamin A is a fat-soluble vitamin, which only exists in animals, while plants only contain caroterophytane;

2. Carotene can be converted into vitamin A in the human body;

3. In the human body, the absorption process of vitamin A and carotene is different. The absorption of vitamin A is active and requires energy, and the absorption rate is 7-30 times faster than carotene. The absorption of carotene is physically diffusive, and the amount of absorption is related to the amount of intake.

The paranuclear site of carotene absorption is in the small intestine, which contains carotene double oxidase, and the carotene that enters the cells of the small intestine under its action is broken down into retinaldehyde or retinol.

Carotene is not vitamin A, vitamin A is a fat-soluble vitamin, vitamin A exists in animals, plants only contain carotene, but carotene can be converted into vitamin A in the human body, vitamin A and carotene absorption process is different.

Carotene: Carotene is the main source of vitamin A, mainly in three forms, the most important of which is - carotene. Food** is mainly dark vegetables and fruits.

It is one of the most common vitamin A supplements. Vitamin A is essential for the development of human vision. If the body is deficient in vitamin A, vision problems can occur.

Carotenoids are a widely distributed class of components in the human diet, in addition to vitamin A activity, it also has a variety of biological activities, some of which are common to them, and some of which are unique to individual carotenoids. For a long time, two carotenoids, carotene and lycopene, have been the core of research, and in recent years, lutein such as lutein, zeaxanthin, and cryptoxanthin have also attracted attention due to their special biological activities.
