Non-Heme Vegetable Iron Is A Reliable Source Of Iron In Combination With Vitamin C

There are two forms of iron in our food, heme iron and non-heme iron. Meat contains heme and non-heme iron, and plants only contain non-heme iron. Heme iron contains the hemeprotein, which allows it to be better absorbed by the body than non-heme iron.

This may appear to be a concern for vegans since their diets only contain non-heme iron, but it doesn’t have to be. Vegans who eat a well balanced plant-based diet eat a higher ratio per calorie of iron than people who eat primarily meat.

Vegans and vegetarians who eat a well-balanced diet also benefit because their diets tend to be high in vitamin C. Vitamin C greatly increases absorption of non-heme iron, by binding with the non-heme iron and allowing it to reach the intestines for absorption into the bloodstream.

So even though non-heme iron is not absorbed as well as heme iron, a vegan and vegetarian diet offers higher amounts of iron and also supplies more vitamin C which makes the non-heme iron as bioavailable as heme iron.

The consumption of non-heme iron is also better for the body because it doesn’t harm the body the way heme iron harms the body.
