Scientists recently took a second look at the oft quoted Nurses’ Health Study, which followed 180,000 female participants. This time they focused on combined intake of magnesium, potassium and calcium and their potential for reducing stroke risk.
Nicola McKeown, director of the Tufts Friedman School’s Nutritional Epidemiology Program, said she wasn’t surprised by the data as these two minerals are found in similar plant-based foods, such as bananas, spinach and soybeans. However, according to Tufts University, these two minerals are sadly absent in many Americans diets. One report found that 45% of the population had typical intakes of magnesium below the estimated average requirement (EAR), which is even less than the RDA of 320 milligrams for women over age 30, 420 milligrams for men over 30.
What’s more, aging tends to inhibit the body’s ability to absorb magnesium from foods. Additionally, certain medications can interfere with mineral absorption. Magnesium and potassium promote steady heart functioning and help control blood pressure, which is the number-one risk factor for stroke.
Are you getting enough of these two powerhouse minerals? If you’re not sure, it is wise to touch base with a trusted healthcare professional.
