The upshot: Charges of iron-deficiency anemia are on the rise.

There are two kinds of iron: heme and non-heme, she identified.
“Heme iron is present in animal merchandise resembling pink meat and is healthier absorbed than non-heme iron in plant-based meals like lentils, spinach, kidney beans, nuts, and a few dried fruit like raisins,” Shapiro defined.
Meals like citrus fruit which might be wealthy in vitamin C may also help the physique higher take in plant-based iron, she mentioned.
However, Shapiro added, iron is usually a double-edged sword: Whereas too little causes anemia, an excessive amount of can tip the size towards iron overload, which will be poisonous.
