What We Need to Stay Healthy

Minerals—inorganic chemical elements or compounds that cannot be produced by the body, but occur in nature—play a key role in helping us function at our best.
 

According to the authors of Minerals: The Forgotten Nutrient - Your Secret Weapon for Getting and Staying Healthy, they are integral to our health. Joy Stephenson-Laws, the lead author and founder of the nonprofit Proactive Health Labs, in Santa Monica, California, suggests getting a full-spectrum mineral test through a healthcare provider to identify any deficiencies or imbalances.

Although the U.S. Food and Drug Administration gives a broad, general Recommended Dietary Allowance (RDA) for minerals, it’s not the most up-do-date or the most specific information according to gender, age or stage in life. The more current Dietary Reference Intakes (DRI) are nutrient-reference values developed by the Institute of Medicine (IOM) of the National Academies—five private, nonprofit institutions that provide independent, objective analysis, located in Washington, D.C., Irvine, California, and Woods Hole, Massachusetts. Intended to serve as a guide for good nutrition by covering 40-plus nutrient substances and more demographically specific than the RDA, the DRI provides a scientific basis for the development of food guidelines in the U.S. and Canada.

This list of important minerals, based on the worldwide studies collected in the journal Minerals, is a good starting point. Another good reference is the extensive chart from the IOM of the National Academy of Sciences.
