Metals in Food and Water: What You Need To Know To Protect Your Health
Although it may sound alarming, metals in our food supply is nothing new. Metals are natural elements found in Earth’s crust, and they often make their way into plant-based foods through irrigation and soil and dust particles, frequently with some “help” from humans (e.g. through sediments from smoking, the use of lead pipes in construction, some forms of paint, and other materials). In the field of food and nutrition, trace elements, or “trace metals,” can actually be beneficial to human health across the life stages. However, with news about “toxic metals” in our food on the rise, we may be feeling concerned about our health and well-being—and the well-being of those we provide food for every day. The good news is that emerging technologies are allowing scientists to test for metals with better and better sensitivity. These findings have advanced federal policies, nutritional guidance, and national health goals. For example, the U.S. Department of Health and Human Services’ Healthy People 2030 General Environment Health lays out objectives for reducing specific metals, as does the U.S. Food and Drug Administration (FDA)’s Closer to Zero: Action Plan for Baby Foods document that was shared in 2020. Since 1961, the FDA has tested and monitors metals and other elements in our food through the Total Diet Study. These efforts are overseen by the FDA’s Toxic Elements Working Group, which aims to reduce consumer exposure to toxic elements in food, dietary supplements, and cosmetics. “Toxic” elements in this context include, but are not limited to, cadmium (Cd), lead (Pb), mercury (Hg), and arsenic (As), all of which you can find more information about below. Lastly, current best-practice manufacturing guidelines during food processing, as well as the documentation of land-use history and water-quality at the farming level of our food supply chain, also help maintain […]
