What foods does vitamin C have? 2 what foods does vitamin c have?

1, orange

The content of vitamin C in 100g fresh orange can reach 49 mg, which is 10 times, 16 times and 8 times higher than pear, apple and banana respectively. In addition, oranges are rich in vitamin B, nicotinic acid, phosphorus, iron and calcium. Eating oranges regularly can promote blood circulation and lower cholesterol and blood lipids.

2. Kiwifruit

Kiwi, also known as Kiwi and longevity fruit, has green flesh like jade, sweet and sour taste and peach shape. Because macaques like to eat, they are called kiwifruit. Every100g of fresh kiwifruit pulp is rich in vitamin C above100g, and eating one kiwifruit every day can meet the demand of vitamin C.

Other fruits rich in vitamin C are cherries, fresh dates, apples, pears, strawberries and persimmons.

3. Cauliflower

Cauliflower, commonly known as cauliflower, is delicious, with less crude fiber and high nutritional value. 100 g cauliflower contains 88 mg of vitamin, which can improve human immune function, promote liver detoxification, improve physique and enhance resistance. Eating about 70 grams of cauliflower per meal can meet the needs of vitamin C.

4. Chinese cabbage

The content of vitamin C in Chinese cabbage per100g is 5 1 mg. Cabbage has not only edible value, but also medicinal value. Rich cellulose can promote intestinal peristalsis, promote digestion and prevent and treat colon cancer.

5.sweet potato

Every100g of sweet potato contains 30 mg of vitamin C, which is also a high-content vegetable, and the vitamin C in sweet potato is not easy to be destroyed whether it is boiled, fried or baked.

Other vegetables rich in vitamin C are persimmon pepper, tomato, spinach, amaranth and water spinach.

6. Vitamin C needs to be supplemented properly.

Although vitamin C has the functions of whitening skin, preventing cancer, preventing cardiovascular diseases and improving immunity, taking too much vitamin C at one time will increase the burden on the kidneys and cause poisoning. Therefore, even if vitamin C is lacking, it should be supplemented in moderation every day, rather than in large doses at one time.

7, can't eat food together

1, pig liver

Vitamin C is easily destroyed by oxidation when it meets trace metal ions, especially copper ions. Pig liver is a kind of food with extremely rich copper content, and the copper content per 100 g pig liver is about 2.6 mg. If taken with vitamin C, copper in pig liver will make vitamin C lose its original biological function. Similarly, sheep liver and beef liver can't be eaten together.

2. Milk

Vitamin C has certain acidity and strong reducibility, and is easy to be oxidized. Milk is rich in vitamin B2, which has a certain oxidation effect. At the same time, vitamin C is easily oxidized by vitamin B2, while vitamin B2 is reduced. At the same time, both of them lose their efficacy and can't achieve the purpose of supplementing vitamins.

3.aspirin

The combination of aspirin and vitamin C will reduce the absorption of vitamin C in the intestine, but vitamin C will not affect the efficacy of aspirin. Therefore, when taking the two drugs at the same time, vitamin C should be taken first, and aspirin should be taken at least after 1 hour.

4.seafood

All kinds of seafood, such as shrimp, crab, clam and oyster, contain the chemical element arsenic. Generally, the content is very small, but the increasingly serious environmental pollution may make the arsenic content in these animals reach a higher level. The valence state of arsenic contained in shrimp is pentavalent. Under normal circumstances, pentavalent arsenic is harmless to human body. Theoretically, high doses of vitamin C (more than 500mg of vitamin at a time) and pentavalent arsenic will be converted into toxic trivalent arsenic (arsenic) through complex chemical reactions, and trivalent arsenic can cause human poisoning when it reaches a certain dose.

5, penicillin drugs

Penicillins should not be mixed with vitamin C for intravenous drip. Because vitamin C has strong reducibility, penicillin will be decomposed and destroyed, and every component in vitamin C injection will affect the stability of ampicillin and reduce its efficacy.

Oral penicillin drugs, such as amoxicillin and penicillin V potassium tablets, are effective in alkaline conditions, and taking them at the same time with slightly acidic vitamin C may reduce the efficacy of penicillin in acidic environment. Therefore, if you need to take vitamin C when taking penicillin drugs, it is suggested that the interval should be 1-2 hours.

6, antacid

The alkaline effect of omeprazole, daxi, weishuping and other drugs for the treatment of digestive tract ulcer will affect the absorption of vitamin C. It is not enough to rely solely on the amount of vitamin C in food, so it is better to supplement it separately.

Patients with gastric ulcer have more stomach acid. Drugs for treating ulcer, such as Weishuping and Daxi, mostly neutralize stomach acid, while the sour and sweet vitamin C is acidic. If you take it at the same time, the effect will have a certain impact. In particular, sodium bicarbonate tablets, a typical alkaline drug, will greatly reduce the role of vitamin C, and should be taken at least 2 hours apart.

7. Sulfonamides

Vitamin C can greatly reduce the solubility of sulfonamides in acidic urine and easily crystallize in renal tubules, thus causing more serious symptoms such as hematuria and urinary incontinence. If you need to take these two drugs at the same time, it is best to have an interval of 2 hours. Drink more water and urinate more after taking it to avoid crystallization and kidney damage.

8. Some nutrients

Vitamin C can affect the absorption and utilization of vitamin B 12, resulting in the deficiency of vitamin B 12, and at the same time can increase the demand of vitamin B 1, so it is necessary to take it at least 2 hours staggered. Taking folic acid and vitamin C at the same time is prone to redox reaction, and folic acid decomposes faster in acidic environment, which leads to the weakening of the effects of the two drugs. When used to treat anemia, folic acid should be taken first, and vitamin C should be taken after an interval of 2 hours.

9. Other drugs

Taking VC for a long time will cause oxalate binding. If you take it with calcium tablets for a long time, it will cause more stones and should be avoided. In addition, vitamin C has anticoagulant effect on heparin and warfarin, which can shorten prothrombin time and weaken the effect of anticoagulant drugs. When both drugs must be used, the interval should be at least 2 hours.

What foods does vitamin C have? The food with the highest vitamin content is 3.

One: carrots

We all know that carrots can be converted into vitamin D in human body, and everything can be changed normally under the action of antimycin, so there will be antimycin in our human liver. Therefore, carrot is a very good source of vitamin A. Carrots can moisturize and strengthen the skin, which is very suitable for people with dry and unsmooth skin, thus improving the skin.

Two: corn

Corn, a favorite food of many people, is a well-known anti-aging food, which contains rich and colorful carotene, especially yellow corn. Carotene can be converted into vitamin A after being digested and absorbed by our body. After product research and development, vitamin A has the effects of delaying aging, nourishing and repairing skin, so as to resist the problem of skin decline caused by dry facial skin.

Three: Sweet potato, especially sweet potato with red skin and yellow heart, also contains rich and colorful carotene, which is also a good source of vitamin A. Moreover, sweet potato also has the functions of clearing away lung and stomach heat, quenching thirst and harmonizing human qi and blood, thus making people's skin recover as soon as possible.

Four: tomatoes

Tomatoes have the functions of clearing away heat and toxic materials, promoting fluid production to quench thirst, nourishing yin and cooling blood, and also have a good nourishing and health-preserving effect on the skin. Moreover, tomatoes also contain rich and colorful carotene, which can be converted into vitamin A in the body.

What is the function of vitamin D?

1, participate in maintaining all normal dark visual effects. Rhodopseudomonas is a photosensitive substance in human macular rod-shaped cells, which is composed of retinol derived from protein and vitamin D. When people go from bright to dark, it takes a while to produce enough rhodopsin, which will lead to blurred vision. This whole process is called dark adaptation. If vitamin D is slightly deficient, it is mainly manifested as an increase in dark adaptation time, and serious deficiency will produce pinkeye.

2. Help to maintain the normal growth, development and physical and mental health of all epithelial cells and tissues. According to the effect of vitamin D on the production of glycoprotein in squamous epithelial cells, vitamin D plays a key role in maintaining the normal growth, development and division of epithelial cells and improving their functions.

When vitamin D is deficient, the skin is dry and not smooth. Lacrimal gland metabolism decline leads to dry eye, corneal dryness and keratinization lead to blindness, and mucous membranes of oral cavity, digestive system, respiratory system and urinary system lose their sense of nutrition and elasticity, which is easy to cause bacterial infection.

3. It can promote all normal hair. Vitamin D can promote the production of protein, and also participate in maintaining the split balance of osteoclasts in bone tissue, thus promoting all normal growth and development of bones, so it is extremely important for children's hair.

4. It can inhibit cancer. Vitamin D and its compounds can promote the normal division of all epithelial cells, have the specificity of anti-promoter genes, and avoid the occurrence of tumors. The original anti-cancer effect, carotene can inhibit cancer by reducing oxygen free radicals and improving antioxidant defense ability.

5. Participate in maintaining all normal immune functions of the body. When vitamin D is deficient, the immunity of the body can be reduced due to the transformation of gamma globulin.
