At our inception 20 years ago, we chose to be different. Unlike other news organizations, we made the decision to provide in-depth, regional reporting free to anyone who wanted access to it. We don’t plan to change that model. Support from our readers will help us maintain and strengthen the editorial independence that is crucial to our mission to help make Western North Carolina a better place to call home. If you are able, please support The Smoky Mountain News.

Sponsored: What foods have magnesium and how much do you need?

Magnesium tends to be kind of a tricky mineral because adequacy is difficult to assess since it is stored in cells and in the bones. 

Why do you need magnesium? Magnesium is involved in a multitude of chemical reactions in your body from protein synthesis to muscle contraction and having a normal heart rhythm. 

What if you don't get enough? A deficiency of magnesium is uncommon but can result in nausea, vomiting, loss of appetite and weakness.

What foods have it? Magnesium is found in many foods, especially those with fiber like green leafy vegetables, nuts, beans, seeds and whole grains. Magnesium is also in animal products. Some of the best sources include: almonds, spinach, cashews, soy milk, and edamame, shredded wheat cereal and potatoes. 

How much do you need? The RDA for 19-30 yr old men is 400 mg/day and women 320 mg/day. 31->51 men - 420mg/day and women 320mg/day. Pregnant and lactating women will need slightly more. 

What if you get too much? As with many vitamins and minerals, it is difficult to get too much magnesium simply by eating foods. The risk for excessive amount of magnesium (toxicity) appears when individuals take supplements. Excess magnesium from supplements can cause diarrhea, cramping and nausea.
