Scope: the micronutrients
The atlas covers the vitamins and the essential minerals. Each record sets out the nutrient's principal tasks in the body, the foods rich in it, the approximate requirement ranges, and the general conditions associated with a deficiency or an excess of it. Requirements change with age, sex and life stage, and that is why the records show estimated ranges rather than a single figure.
How the filters work
You can sift the records by type, vitamin or mineral, and by the area they relate to: energy metabolism, bone health, immunity, the nervous system. Once you see which foods contain a nutrient, you can move to those foods' records through the Foods Atlas; the two atlases are linked so that each completes the other.
An important limit: the supplement decision is yours and your doctor's
This atlas does not and cannot tell you which supplement to take; that decision is made with a doctor who can see your blood values and your medical history. The purpose of the records is to let you see what a varied diet already covers, and to help you hold a better-informed conversation with your doctor. Remember that not every product labelled "natural" is harmless, and that an excess of some nutrients can also cause problems. For the general frame, see the Nutrition section.
