Much of the grains we consume these days are milled, and therefore stripped of many of the nutrients our body needs. Wheat for instance, loses half of its B vitamins, 90 percent of its vitamin E, and virtually all of its fiber in the milling process. Fortification adds back some, but not all, of the lost nutrients.

Our diets are too high in salt and sodium. The optimal limit for sodium is 1,500 milligrams a day, equivalent to the amount of sodium in about two-thirds of a teaspoon of salt.
