Vitamins are essential nutrients for the body.  It is classified as fat soluble (A, D, E, K) and water soluble (B and C complexes).  Vitamin C (C6H8O6), also known as ascorbic acid, is one of the most important nutritional sources due to its antioxidant properties and functional activity that protect from free radical damage.  Its discovery is based on scorbutic, an ancient hemorrhagic disease.  Plants and most animal species do not need to activate vitamin C externally, as they have the ability to synthesize vitamin C from glucose and galactose via uronic acid acid.  Humans cannot synthesize vitamin C due to the lack of enzymes necessary for this biosynthesis to take place.  It is extremely important to take this vitamin from outside.  Vitamin C deficiency; it can cause bleeding gums, infections, scorbutic, and anemia.  While animal foods are poor in terms of vitamin C, plant foods are rich.  It is recommended to consume at least 60 mg of ascorbic acid daily.  We have listed the ascorbic acid values ​​of some foods that can be found in everyone’s closet for you below.  You can find the vitamin C value of more nutrients at the US Department of Agriculture (https://fdc.nal.usda.gov/)

When vitamin C comes into contact with air, it is oxidized with the oxygen of the air and reduces the vitamin activity.  The specific properties of vitamin C, which is affected by environmental conditions such as temperature, light and air, are lost as a result of enzymatic oxidation in the presence of air oxygen.  Most of the vitamin C can be lost while the vegetables are picked and kept after cooking.  For this reason, we should not forget that citrus fruits are an important source of vitamin C intake and we should consume them immediately after the peel is cleaned.

Vitamin C has various benefits.  We pay attention to its consumption in order to protect against colds, especially in winter.  Two-time Nobel Prize winner Linus Pauling has worked on vitamin C.  As a result of these studies, he discovered that the vitamin C taken every day protects the body against colds and published this research under the title of vitamin C and the common cold.  Other benefits of vitamin C are as follows:

  • Strengthens immunity
  • Increases iron absorption
  • Balances blood lipids
  • Prevents gout attacks
