      HEADLINES:

Arming India’s poor against the pandemic

      WHY IN NEWS:

SYLLABUS COVERED: GS 3: Science

      LEARNING: 

For PRELIMS it is important to understand how Vitamins and Mineral work inside our body and their formation .

For MAINS can you device a scheme for inclusion of Vitamins and Minerals in Rural India’s diet ?

      ISSUE: 

Vitamin D is produced when sunlight falls on the skin and triggers a chemical reaction.

VITAMIN D DEFICIENCY

  • It is also associated with infections in the respiratory tract and lung injury.
  • Vitamin D is known to help in having the right amount of calcium in the bones.

VITAMIN-D RESTORATION

  • Catalyse the process of protecting cell membranes from damage.
  • Preventing the inflammation of tissues and helping stop tissues from forming fibres
  • Weakening bones from becoming brittle.
  • Which can lead to osteoporosis.

The levels of vitamin D (and calcium) in human (and animal) bodies need to be monitored and when necessary.

VITAMIN D FORMULA

  • It is produced when sunlight (or artificial light, particularly in the ultraviolet region of 190-400 nm wavelength) falls on the skin .

This triggers a chemical reaction to a cholesterol-based molecule, and converts it into calcidiol (adding one hydroxyl group, also called 25(OH)D technically) in the liver and into calcitriol (or 1, 25(OH)2D) in the kidney.
 

  • It is these two molecules that are physiologically active.

LEVELS OF VITAMIN D

  • Level of 25-OHD in the range 30-100 ng/ml is thought to be sufficient for a healthy body.
  • Levels between 21-29 ng/ml are considered insufficient.
  • Levels below 20 ng/ml mean the individual is deficient in the vitamin.

      IASbhai WINDUP: 

NUTRITIVE FOOD

  • A nation of abundant sunshine, is surprisingly found to have a massive burden of vitamin D deficiency.

Schemes cover only pulses and cereals . Vitamins do not come into picture .

Given the deficit in vitamin D (indeed in many other vitamins, and calcium), it is highly desirable for the governments to:

(a) Consult nutrition experts and institutions to advise and suggest the type of nutritive items that can be added to the current ‘ration’ food given to the poor, and the meals given to school children.

(b) In any case, supply free of charge, vitamin D, other vitamins and calcium, in consultation with medical and public health experts regarding the dosage, frequency and other details.

  • There are excellent Indian companies that manufacture these.
  • Since sunlight in important for the generation of vitamin D, tropical countries have an advantage over the northern countries.

With these steps, India will have armed its poor against not just the current, but future pandemics as well.
