How much do you really need? Your body needs only small amounts of vitamins and minerals. But because what the body manufactures if often not enough, these must be obtained from your diet and from supplements. While most books provide limited information, this book shares complete information that you are ever likely to need about vitamins, minerals, and amino acids. The RDA (Recommended Daily Allowance) tables provide expert guidance about the amount of each nutrient you need every day.
The best sources: A balanced diet is the most sensible way of getting a sufficient quantity of these nutrients. The rich and natural sources of all nutrients are listed individually to help you choose the right foods. Some popular myths have been corrected (Spinach is especially rich in iron - false. Extra vitamins lengthen your life - false) to enable you build a strong immunity system for a healthier, and a more active life.
