Thank you for this informative post. Really useful information. It is frustrating that good nutrition is not considered enough in standard healthcare. Vets and farmers tend to lay a lot of emphasis on getting the right balance of vitamins, minerals, protein etc for animals and yet human health care professionals give it very little emphasis. I really believe that for a lot of chronic conditions, an analysis of heavy metal contamination and basic vitamin and mineral levels would be extremely helpful and ultimately save our healthcare systems £$£$£$£$£$£$.
