During the first two months of life, the human body synthesizes vitamin C on its own. Ascorbic acid strengthens the immune system, fights viruses and bacteria, helps prevent various kinds of diseases, prolongs the youth of the body, and this is not the whole list of its effects.

Effect of vitamin C on the body

Vitamin C (ascorbic acid) has wide range effects on the body. It improves immunity, takes part in the formation of antibodies and in normalizing the metabolism of fats, proteins, carbohydrates, and increasing the supply of glycogen in the liver. Ascorbic acid helps increase blood flow and heart rate, reducing blood pressure, expansion of capillaries and arterioles.

Vitamin C is involved in large quantities biological processes. Thus, it affects the synthesis of collagen, a protein that forms connective tissue that cements the intercellular space. The main functions of collagen include protection blood vessels, organs, muscles, joints, bones, formation of skin, bones, ligaments, teeth. He acts as protective barrier against infections, diseases, promotes healing of bruises, fractures, wounds.

For immune system Vitamin C is very important as it supports the functioning of white blood cells and the production of antibodies. It also promotes the formation of interferon (a substance with anticancer and antiviral effects). Vitamin C, due to its antioxidant properties, protects against negative impact antioxidants, helps prevent symptoms of aging, heart disease and cancer. In addition, ascorbic acid has a positive effect on the functioning of the cardiovascular, nervous, endocrine and other systems.

Daily value of vitamin C

The daily requirement of the human body for vitamin C is not the same for everyone and depends on several factors: the availability bad habits, breastfeeding or pregnancy status, work performed, gender, age. Experts provide average figures for the statistical average healthy person: 500-1500 mg per day - therapeutic norm and 60-100 mg daily is the physiological need of the body.

The need for vitamin C increases toxic effects, fever, stress, illness, hot climate, Daily requirement Vitamin C increases contraception. The norm depends on age - than older man, the larger it is. For example, the requirement for an infant is 30 mg, and for an elderly person - 60 mg. The daily intake increases during pregnancy (70 mg) and lactation (95 mg).

Signs of vitamin C deficiency in the body

Statistics show that it is children of preschool and school age suffer from a lack of vitamins that are necessary for their normal growth and development. A lack of vitamin C was found in 90% of children (the study was conducted). In the bodies of those children who were in the hospital, a deficiency of ascorbic acid was found in 60-70%.

Vitamin C deficiency increases in the winter-spring period, which entails a decrease in immunity and an increased possibility of developing gastrointestinal or respiratory diseases. Deficiency can be exogenous or endogenous. In the first case, there is little vitamin in food, in the second, the vitamin is poorly absorbed. Long-term vitamin deficiency can lead to the development of hypovitaminosis. Vitamin C deficiency in the body can manifest itself the following symptoms: depression, joint pain, irritability, dry skin, hair loss, lethargy, tooth loss and bleeding gums, poor healing wound

Animal products contain vitamin C in small quantities. These are mainly the kidneys, adrenal glands, and liver of animals.

There are a number of herbs that contain vitamin C in sufficient doses. Foods should be eaten every day and preferably in unprocessed form. After all, biochemical processing, storage and heat treatment contribute to the destruction of a large part of the vitamin.

The drug promotes the formation of intracellular collagen, strengthening the structure of the walls of capillaries, bones and teeth. The drug "Ascorbic acid" is vitamin C itself. Products cannot always fully provide the body with it.

The product takes part in the processes of cellular respiration, iron metabolism, protein and lipid synthesis, carbohydrate metabolism, tyrosine metabolism, and redox reactions. The use of "Ascorbic acid" reduces the body's need for pantothenic vitamins A, E, B. The vitamin C content in the preparation is close to 100%.

Indications

People who long time suffer from a lack of vitamin C in the body, they may be prescribed certain drugs. As a rule, tablets are available containing 250 mg of ascorbic acid or 1000 mg (indicated only for the treatment of hypovitaminosis).

The benefits of vitamin C on the human body cannot be overestimated. We need this substance like air and water. With its deficiency, extremely unpleasant and dangerous diseases, including scurvy. So that the body receives necessary substances, including ascorbic acid, you need to properly organize your diet and diet. Of course, during cold periods it is best to take vitamin complexes, but you shouldn’t give up foods containing vitamin C. So what foods contain vitamin C?

What foods contain vitamin C?

As you know, the most vitamin C is found in vegetables, fruits and berries. Some of these products exceed 100 grams, sometimes several times, read more!

For convenience of consideration, we will take the amount of ascorbic acid in mg per 100 grams of product.

In fact, the content of vitamin C in products has a very wide range: from 1 to 1500 mg per 100 g of product.

For example, with meat we practically do not get vitamin C: the content of ascorbic acid in products of animal origin is minimal - the same 1 gram that we mentioned just above. More ascorbic acid is found in beef, chicken and pork liver - about 33 mg. To provide the body with the necessary daily intake of vitamin C, you need to eat an unrealistically large amount of meat and meat products. By the way, some peoples of the Far North receive a sufficient portion of ascorbic acid from meat; due to the lack of vegetables and fruits, they are forced to eat mainly meat and fish in quantities that are unlikely to be tolerated by residents of the European side of Russia. True, northern peoples have the opportunity to feast on unpretentious berries of cranberries, lingonberries, blueberries, bearberries, and cloudberries, which contain the daily requirement of ascorbic acid.

Which vegetables and fruits have a lot of vitamin C?

Fruits are very rich in vitamin C, but many vegetables are ahead of them in terms of its content in their composition. Guava is the leader in the amount of vitamin C per 100 grams of fruit: 230 mg. The daily requirement of ascorbic acid for children (45 mg) contains 100 grams of kiwi, pineapple, melon, papaya, apples, mango.

But the berries, which are very common in our country, are much richer in vitamin C. Sea buckthorn and black currant contain 200 mg each, which is the approximate norm for pregnant and lactating women, and people of both sexes who have a cold.

Is lemon the richest food in vitamin C?

There is an opinion that the most ascorbic acid is found in lemons and oranges. But this is nothing more than a delusion. Despite the fact that tea with lemon is very beneficial for our body, citrus fruits are not record holders for the content of “ascorbic acid” in their composition. You could even say that in the list of foods that contain vitamin C, citrus fruits are almost at the tail end. Of course, there are products containing much less ascorbic acid in their composition than is contained in lemon, in some products this vitamin and is completely absent. But the fact remains: 100 grams of lemon contains about 45 mg of ascorbic acid (with the average daily requirement for a person being 70 grams). In addition, it is rare to eat a whole lemon like an apple. Most often, we put a small slice of this fruit in tea, therefore, the dose of vitamin C entering our body with lemon is very small. In this sense, even oranges are healthier. In them more content ascorbic acid - 65 mg, which is the daily requirement ordinary person. We recommend reading the article linked above to find out what the daily value for an adult is, depending on a number of factors.

But the leader in the content of ascorbic acid in the composition is rose hips, or more precisely, the fruits of this plant. Moreover, dried fruits contain as much as 1500 mg of vitamin C, and fresh ones - 700 mg. Therefore, rosehip is very useful for colds, for increasing immunity, for healthy skin, hair, nails and most different systems human body.

Vegetables and mushrooms containing vitamin C

The list of vegetables containing large quantities of vitamin C is much wider than the similar list of fruits. This includes peppers (hot, red, sweet), and Brussels sprouts, white cabbage, broccoli, cauliflower, even pickled, and lettuce, and greens. These products contain daily norm ascorbic acid for an adult. The record holder on this list is all types of peppers - they contain 200 mg of vitamin each. Therefore, during the cold season, they will be especially useful. fresh salads with a lot of pepper.

Mushrooms also contain a lot of vitamin C, and in the dried form of this product there is more ascorbic acid than in the fresh form.

When compiling your diet based on a list of foods containing a lot of vitamin C, remember: an overdose of ascorbic acid is no less dangerous than its deficiency. True, in order to regularly receive huge doses of ascorbic acid from foods, you need to eat a lot of rose hips, peppers and herbs combined.

Vitamin C (L-isomer of ascorbic acid) is a water-soluble biologically active organic compound, related to glucose.

Ascorbic acid gets its name from the Latin “scorbutus” (scurvy). Back in the 18th century, long before the discovery of vitamins, it was found that citrus juice contained a certain substance that prevented the development of scurvy in sailors during a long voyage. It is known that scurvy is a disease caused by a severe lack of vitamin C in food (vitaminosis).

What functions does vitamin C perform in the body?

Vitamin C is one of the most effective antioxidants; it protects body cells from harmful effects free radicals. Ascorbic acid is a participant in the process of biosynthesis of collagen and its precursor - substances that are necessary for the formation of complete bone and connective tissue. It is needed for normal hematopoiesis and the production of catecholamines and steroid compounds in the body. Vitamin C is able to regulate blood clotting and normalize the permeability of the walls of small blood vessels. It can prevent the development of hypersensitivity reactions (allergy) and reduce the severity of the inflammatory process.

Ascorbic acid is necessary for humans to protect their body from negative consequences impact. It has been established that the concentration of ascorbic acid salts in the “stress hormones” secreted by the adrenal glands is very high.

Under the influence of this vitamin, it is strengthened and recovery processes are activated.

Important: there is reason to believe that vitamin C is an important factor in, in particular - malignant tumors organs digestive tract, urinary and reproductive systems.

Ascorbic acid accelerates the process of elimination from the body heavy metals and their connections.

Vitamin C prevents the oxidation of cholesterol and its deposition on vascular walls, thus providing an antiatherosclerotic effect. Its sufficient content increases the stability of other vitamins - A, E and B compounds.

The compound does not have the property of being deposited and is not synthesized in the body, and therefore a person must constantly receive it from the outside through the diet (with food and drinks).

Natural sources of this compound are many vegetables and fruits. Animal products contain very little vitamin C.

Since ascorbic acid is water-soluble and loses stability when heated, it is lost during cooking (thermal) processing. most of this is vital important vitamin. It is advisable to consume vegetables and fruits containing it raw.

Animal sources:

  • beef and pork liver;
  • animal kidneys and adrenal glands;
  • mare's milk;
  • goat milk.

Plant sources:

  • leafy greens ( , );
  • horseradish;
  • onions (green and onions);
  • citrus fruits (oranges, etc.);
  • cabbage (any variety);
  • sweet pepper ("Bulgarian" and hot cayenne);
  • tomatoes;
  • potatoes (only baked in their skins);
  • green pea;
  • apples;
  • currant;
  • peaches;
  • apricots (including dried apricots);

note:the content of “ascorbic acid” is very high in the fruits of rowan, rose hips and. Vitamin drinks of them allow you to cope with seasonal (winter-spring) hypovitaminosis.

Plants that can be used to prepare vitamin infusions:

  • burdock (root);
  • pepper;
  • plantain;
  • yarrow;
  • pine needles;
  • raspberry (leaves);
  • violet (leaves;
  • fennel (seeds);
  • nettle.

Sufficiently long storage of products and biochemical processing negatively affect the level of vitamin C in food products. One of the few exceptions is dried fruits rose hips, in which up to 1 year or more is preserved exclusively high concentration ascorbic acid (up to 0.2%). Rose hips contain many other useful substances– vitamins K, P, tannins, sugars, etc. Syrup is made from the fruits (it can be purchased at the pharmacy), which will help you easily overcome hypovitaminosis.

Important:Of all the dishes that have undergone heat treatment, the “record holder” for the amount of preserved vitamin C is boiled white cabbage. When cooked for 1 hour (no more!) 50% of the “ascorbic acid” remains in it (relative to the initial level). Approximately the same amount of vitamin is retained in freshly prepared potato soup.

Vitamin C intake standards

An increased amount of “ascorbic acid” is required by patients, as well as those who take medications, etc.

Important:It has been found that the need for vitamin C increases significantly in people suffering from nicotine addiction; in addition, tobacco combustion products impair digestibility useful connection. Smokers, as well as those who regularly consume alcohol, are recommended to consume 20-40% more vitamin C.

It is recommended that meat lovers consume a lot of vitamin C. This is necessary to reduce negative impact nitrogenous compounds, present in large quantities in muscle tissue animals. Special attention It is worth paying attention to this vitamin for those who prefer meat in the form of sausages and smoked meats. As one of the preservatives in the manufacture of such products, the nitrogen-containing compound saltpeter is often used, which can be converted in the stomach into nitrosamines that provoke development.

The daily value depends on a number of factors, including:

  • climate;
  • environmental situation in the region;
  • occupational hazards;
  • smoking (including passive smoking);
  • alcohol consumption;
  • age;
  • pregnancy;
  • lactation.

Note: Studies have shown that in hot or very cold climates a person needs on average 30-50% more ascorbic acid.

The average adult needs to consume 60-100 mg of vitamin C per day. If ascorbic acid preparations are prescribed as part of complex therapy diseases, normal daily dosage- from 500 to 1500 mg.

During pregnancy, women need to consume at least 75 mg, and during breastfeeding– at least 90 mg of vitamin C.

Infants from birth to six months of age require 30 mg, and babies from 6 months to 1 year - 35 mg of vitamin C per day. Children from 1 to 3 years old require 40 mg, and from 4 to 10 years old - 45 mg daily.

Features of taking vitamin C

It is advisable to divide the recommended daily dose for several techniques, i.e., use the principle “ fractional meals" The human body quickly uses up water-soluble vitamins and quickly excretes the “excess” in the urine. Thus, it is much better to maintain a constant concentration of ascorbic acid by taking medications or consuming fruits and vegetables in small portions throughout the day.

Hypovitaminosis of vitamin C was detected in 60-80% of children of preschool and primary school age. Almost identical data were obtained from studies conducted in various regions of the Russian Federation.

Important : the deficiency of this compound is especially pronounced in winter and spring, when there are few fresh vegetables and fruits in stores, and in those plant products, which are sold year-round, there is much less ascorbic acid than in freshly picked ones.

Hypovitaminosis leads to a decrease in immunity, as a result of which the frequency of respiratory and gastrointestinal infections increases (by 25-40%). Due to a decrease in the phagocytic activity of leukocytes towards foreign bacterial agents, diseases are much more severe.

The causes of hypovitaminosis can be divided into endo- and exogenous.

Internal causes are impaired absorption and ability to assimilate ascorbic acid.

The external reason is a long-term lack of vitamin intake from food.

With a deficiency of vitamin C, the following clinical manifestations of hypovitaminosis may occur:

  • increased bleeding of gums;
  • pathological mobility and loss of teeth;
