Every person in this country, and every other country for that matter, deserves to be well fed, and to have access to decent nutritional sources, and healthcare. Who on earth are you to suggest that people don't need good food, they just need to get outdoors?
Did I say people don't need a good diet and they just need to get outside more? No of course I didn't. I said people need to get outside to increase their Vit d levels as that is not only the best way to get vit D, but it is free. Vit D is only found in small number of foods (source NHS website).
I also suggested a cheap way to get dietary vit D was supplementation or cod liver oil.
Yes, I am suggesting your body store Vit d for 6 months because it does. It then gradually uses it up until you have more sun/take a supplement/eat something containing vit D.
Google this research paper if you don't believe me:
Vitamin D Stored in Fat Tissue During a 5-Year Intervention Affects Serum 25-Hydroxyvitamin D Levels the Following Year
The pertinent line being 'In the vitamin D group, adipose tissue vitamin D levels decreased by 52% over 12 months'
There are other papers but that is a good start.
For some reason you are grandstanding against me about vitamin d and trying to imply I said people don't need a good diet. Of course people need a good diet I don't understand why you think I believe they don't.
