To Heme or Not to Heme?

July 23, 2020 | Lauren Widawsky, RDN


Approximately half of all cases of anemia are due to iron deficiency, which is the most common nutritional deficiency. Symptoms, which include fatigue, pale skin and fingernails, weakness, dizziness, headache or swollen tongue often go unnoticed.

Dietary iron can be found in two forms: heme from meat and other animal sources and non-heme from plant and iron-fortified foods. Heme iron is highly bioavailable compared to non-heme but pairing non-heme iron with vitamin C can enhance the body's absorption of the non-heme form.

Aim to consume about 18 milligrams of iron daily. Excellent food sources include beef-liver, seafood, canned white beans, fortified cereals, leafy greens and tofu. Cooking with a cast iron skillet is also a great way to incorporate more iron into your diet.
