CORONA and INDIA's VITAMIN D DEFICIENCY: Dr. John Campbell: Vitamin D deficiency is incredibly prevalent in India which very adversely affects immune function.If you are in India, put this on your FB page. The simple fact of the matter is that people who are deficient in vitamin D are going to be immuno-compromized and more likely to get severe inflammation and therefore- as many studies have shown - and more likely to getting sick. So do publicise this. This is really important at the moment. (But it is important any time).The studies (30 in number) show that prevalence of Vitamin D deficiency ranges from 40% to 99%. These are horrendously high levels. Most of the studies are reporting a prevalence of 80% - 90% of people’s vitamin D deficiency in India. This is really quite a startling figure. These very high levels of deficiency of vitamin D let very reasonably assume that very high levels of immuno-compromize simply through lack of vitamin D.And a large part of the population is also largely vegetarian, so they are not getting a lots of vitamin D from their diet - and they are not getting it from the sun.It is prevalent in all age groups and high risk groups alike.And you also actually see a lot of children who actually have rickets, and reduced growth because of the lack of vitamin D and calcium. But this is very easy to correct.A major source of vitamin D is synthesis in skin through exposure to sunlight, ultraviolet B (UV-B) radiation., wavelength 290-320 nm; you get it in fish, in vitamin D fortified food and vitamin D supplements.There is an interesting correlation about vitamin D from eating fish: People in Kerala where they eat a lot of fish died less in the 1918/19 pandemic.Vegetables and grains are poor sources of vitamin D. Rice and lentils/ dhal or chapati/roti and dhal, these foods basically don’t contain no vitamin D actually.Without getting sufficiently into the sunshine the deficiency is inevitable.Other factors: Latitude and solar zenith angle, basically the sun needs to be higher than 42 degrees in the sky to make any vitamin D. In Middle Europe this is only a given in 6 months of the year - from April onwards.Even when there is so much sunshine in India a lot of it is not being used to make human vitamin D via the skin.And the atmospheric pollution is a huge factor in India. It is getting better, but the cities like New Delhi and Mumbai are terribly polluted.And melanin pigmentation is a strong factor (the darker the skin the less vitamin D production is possible in the skin).Necessary serum levels of vitamin D in the blood (threshold levels, deficiency, insufficiency sufficiency) etc..see in the video.If you are low in vitamin D you will not absorb calcium….Consequences of Vitamin D deficiency: Rickets, Muscle strength reduction. Autoimmune diseases, depression, suicide, Parkinson’s, cancer, infections tuberculosis, obesity, diabetes mellitus type 2;vitamin D is important for: immune function, inflammation, cell proliferation and differentiation…Vitamin D is definitely necessary for immune protection, for immune function, and the prevalence in India is that 80 90 % of the people in India are deficient - quite ironic in such a sunny country.So what the heck to do about this?The authors suggest Create awareness among the public and healthcare providers about the importance of vitamin D - and the consequences of deficiency^. Indian diet generally fails to satisfy the daily requirement of vitamin D for a normal adult.Need for fortifying various foods with Vitamin D, through national programs.This silent epidemic should be addressed properly with concrete public health action!
