Vitamin C

Vitamin C, or ascorbic acid (in English: Ascorbic acid), is soluble vitamins in the water, and is one of the basic foodstuffs; Where should the daily diet contains vitamin C; Because the body can not Tsenaih or store, and contributes vitamin C to support the body's growth and development, in addition to helping the absorption of iron in the body, lowering blood cholesterol levels, and protecting the body from various harmful effects of free roots pollutants and toxins; So for being an antioxidant, [1] [2]

Vitamin C is important for bones, skin, tissue, promotes wound healing. Can get vitamin C from fruits and vegetables, such as citrus oranges and grapefruit, as well as tomatoes, sweet peppers green, red, vegetables, green leafy, broccoli, can also be added vitamin C to some cereals and juices Tdamiha. [3]

The recommended amount of vitamin C

The following table shows the recommended quantity of food out (in English: Recommended Dietary Allowances) of vitamin C by age and sex: [4]

Increase vitamin C in the body

The body needs to get vitamin C for growth naturally, which gets rid of the excess amount of this vitamin through the urine is not stored, and therefore must be taken regularly to reduce the risk of Bnqs, [3] and may not cause high doses of vitamin C have serious adverse effects; Where it is detoxified rare, but it may cause some side effects, and the most common symptoms: diarrhea, nausea, abdominal cramps, and other gastrointestinal disorders caused by osmotic pressure of vitamin C is absorbed in the gastrointestinal tract. [4]

According to the Food Council and nutrition (in English: Food and Nutrition Board), it can eat the amount exceeds the maximum acceptable level (in English: Tolerable Upper Intake Levels) of vitamin C in the long term to increase health risks, so if the consumption of this amount, it is recommended that under the supervision of a physician. The following table shows the top limit recommended by vitamin C by age and sex: [4]

Side effects of increased vitamin C in the body

Digestive system problems

The intake of vitamin C by mouth safe when taken the recommended dose, but can be taken in larger quantities than the recommended limit can cause some digestive disorders light, in addition to some side effects, such as nausea, vomiting, heartburn, cramps in, and other symptoms, they may also include severe diarrhea, which increases the chance to happen when eating amounts of more than 2,000 milligrams per day, [5] [6] the diarrhea and nausea more symptoms resulting from excessive intake of vitamin c commonly used, as it may cause reflux esophageal, but it has not been proven yet. [1]

Formation of kidney stones

Can eat the amount of more than 1,000 milligrams per day of vitamin C to raise the risk of recurrence of kidney stones in people who have suffered previously; [6] where secreted vitamin C in excess of the body's need in the form of oxalate (in English: Oxalate) through the urine, and can these oxalate be associated with minerals and form crystals may be kidney stones. [1] [7] reported a review of the University of Wake Forest University School of Medicine in 2004 to supplement the consumption of vitamin c high amount of 1,000 mg daily for 3 days in addition to avoiding foods rich in consumption calcium and oxalate such as milk products and derivatives lifted from asking oxalate through the urine by up to 56%, as observed saturation of urine calcium and oxalate significantly, which may be associated with an increased risk of kidney stones, [8] [1] while the results of other studies mixed on the secretion oxalate in the urine and the risk of formation of stones due to intake of vitamin c in large quantities; As it is not linked to the lifting of the risk of these kidney stones, such as a preliminary study from Harvard University reported in 1999 reached the vitamin C consumption to 1,500 milligrams a long time extended for 14 years. [4] [9]

To influence the levels of some nutrients

Can excessive intake of vitamin C that weakens the body's ability to metabolism and other nutritional elements; As it may reduce the levels of vitamin B12 and copper in the body, [5] On the other hand contributes to vitamin C to improve the effectiveness of the absorption of iron and in particular type is not HEMI of it, which is available in the foods source plant, which is good for individuals who rely on their diet these foods to get adequate amounts of iron. [1]

But it is worth noting that people who suffer from iron overload (in English: Iron overload), or hemochromatosis (in English: Hemochromatosis) should consult a doctor before taking supplements of vitamin C; Where vitamin C excessively to eat through dietary supplements can lead to increased likelihood of iron toxicity, which may cause significant damage to the heart, pancreas, liver, thyroid, and central nervous system. [1]

Bone spurs

I found one of the preliminary studies from the University of Duke University Medical Center in 2004 and carried out on animals that the levels are very high vitamin C in the long term increases the likelihood that the growth of a bump at the joints, or the so-called Balnapth bone (in English: Bone spurs), which increases the pain arthritis and damage in people with rheumatoid arthritis, degenerative knee, [10] on the other hand, a small study of King George Medical University University in 2015 showed that people who have to have a lower vitamin c consumption and vitamin d increase the risk of contracting arthritis Altkensa knee, [11] advised consumption of an adequate amount of vitamin c to reduce the risk of rheumatoid arthritis, and to maintain the health of joints suffering from rheumatoid arthritis (in English: rheumatoid arthritis). [12]

Interfering with some medications

One of the evidence suggests that it can eat vitamin C supplements that weakens the body's ability to increase protein levels of lipoprotein high density (English: High-density lipoprotein), or what is known Balchollstrul beneficial in people who are taking medications containing combination niacin simvastatin (in English: Niacin- simvastatin); Combining this medicine between vitamin niacin and a drug statin simvastatin, which is taken to treat high cholesterol in the blood, cholesterol beneficial and helps to reduce cholesterol levels of LDL in the blood, so it is advisable to consume these drugs to consult a doctor to use them more and avoid reducing its impact, as it should be noted it is about the extent of the effect of vitamin c there is not enough information on the effectiveness of other drugs. [5]

Other caveats associated with the consumption of vitamin C

Although vitamin C consumption by most people recommended amounts is safe mostly, but it may lead to vomiting, heartburn, and stomach cramps, headaches, and other symptoms in some people, [6] and that eating a large vitamin C amounts It may lead to the emergence of other side effects, such as the erosion of tooth enamel and allergic reactions, and others, but there is still a need for more studies on it. [4] it should also be mentioned that vitamin c consumption is linked to certain certain categories Bmhaazir, and remind them what comes : [6]

  • Pregnant women and breastfeeding women: can eat the amount of vitamin C in excess of the recommended quantities during this period can cause problems for the newborn child.
  • Children: Eating as amounts exceeding the recommended amount of vitamin C by this category are likely to be unsafe.
  • Diabetes: Vitamin C can raise the levels of sugar in the blood, it has found that intake of more than 300 milligrams per day of vitamin C increases the risk of death from heart disease among older women age women with diabetes.
  • People with a lack of enzyme necessary for the process of metabolism: the so-called hydrogen Bnazaah glucose-6-phosphate (English: Glucose-6-phosphate dehydrogenase) and to provide red-powered blood cells resulting from the metabolism, has shown that large amounts of vitamin C can cause Teixra in the red blood cells of people with this condition, so you should avoid eating excessive amounts of it.
  • Subject to the process of kidney transplantation: (English: Kidney transplant); Where it is believed that it could be a long-term use of high doses of vitamin C before it undergoes a kidney transplant can increase the risk of rejection of the process of agriculture, or delay the time it takes the ability to total cultivated for the performance of its functions.

Lack of vitamin C in the body

The vitamin C deficiency is rarely relatively in developed countries due to the availability of fresh sources, and add it to some foods and dietary supplements supported, and it should be noted that those smokers and low income earners were the most vulnerable to the risk of a lack of vitamin C. [13] [14] Although vitamin a deficiency is uncommon, but some groups rise with the risk of exposure to this deficiency, such as: alcoholics, people, vegetarians, and those who suffer from socio-economic status of poor, in addition to dialysis patients, when using certain medications, people who have a history injury to poor absorption, or surgery in the digestive system, according to what I said a review published in the Cleveland Clinic Journal Journal of Medicine in 2016. [15] it should be noted that it can be symptoms of vitamin c deficiency acute take months to develop, but there are some signs that you should pay attention to it. [13] the symptoms that can be caused by vitamin c deficiency recall the following: [16]

  • Anemia.
  • Bleeding gums or nose.
  • Gingivitis.
  • Reduced ability to fight infection and heal wounds.
  • Dry skin and Takecrh.
