In our grandmother's time everyone got their Vitamin D from fish. Every nation got fish from somewhere and they gave children Cod Liver Oil in the darker months. (no it is not availiable in a fish stick or a fish burger from McD's). It is a fact and I have talked to hundreds when I worked in all those stores. Even from the Caribbean..everywhere. We now sadly have an entire nation of people who have incredibly low Vitamin D levels. If we check out food sources we will see where we can get some from. Minerals as of themselves are becoming incredibly depleted from our soils. Then you have all the yahoos who feed their families junk. should do a post I guess
