You can stimulate bone marrow to produce more white blood cells (if you have a cold, fever, any debilitating disease) with nutrition? This should not come as a surprise, but in the new time which we live we find it hard to see that our body doesn’t need synthetic medications to run vital process. We need food. Food that at some point walked or grew on the earth. So eat 2 vegetables to 1 fruit for thirty days and see how it makes you feel.
