For some of us the remedy is only a few clicks away. Print the article and take to your doctor if you have to. And don't let doctors tell you it won't make a difference. Our bodies are made of vitamins and minerals...every bone, every tissue. And other nutrients found in foods control our metabolic processes like proteins and Omega 3 fatty acids. It's okay if they tell you to be careful, but don't let them tell you it won't help.
