80% of Americans are Deficient in Magnesium
First published January 14, 2015;
Most US adults ingest only about 270 mg of magnesium a day, well below the modest magnesium RDAs of 420 mg for adult males and 320 mg for adult females. (The Recommended Daily Allowance, RDA, is the minimum amount for a healthy person; A-Fib patients are frequently extremely deficient.) This creates a substantial cumulative deficiency over months and years.
“At least 80% of Americans are deficient in magnesium.” Why? Magnesium used to be plentiful in fruits, vegetable and grains, but decades of industrial-scale farming have stripped the soil of minerals like magnesium.
One study found that the nutrient content of crops has declined by as much as 40% since the 1950s. “It’s now is almost impossible to get adequate amounts of magnesium from food.”
