Whole Foods For Complete Nourishment The healthiest way to meet nutritional needs is to simply eat a diet rich in whole foods. Food-sourced vitamins and minerals are superior to their laboratory-created counterparts. As I noted earlier, many calcium supplements are derived from nonfood sources — oyster shells, bovine bone meal, or dolomite — none of which the body is able to use efficiently. Again, the more work the body must do to assimilate nutrients, the less usable energy it will be left with. Salt is another illustration of this. Salt derived from the earth or the sea is often added to food during processing; salt is rarely consumed in its alternative form — plants. Yet, that is a much better way to get sodium in your diet: Let the plant draw and assimilate it and other minerals from the soil or sea, doing most of the work for you. My favorite source of sodium is raw dulse. A sea vegetable, dulse is exceptionally healthy, offering a plethora of minerals that help prolong hydration and therefore endurance.
