Iron from different foods is absorbed and processed differently by the body; for instance, iron in meat (heme iron source) is more easily absorbed than iron in grains and vegetables ("non-heme" iron sources). [32] Minerals and chemicals in one type of food may also inhibit absorption of iron from another type of food eaten at the same time. [33]
The absorption of dietary iron is a variable and dynamic process. The amount of iron absorbed compared to the amount ingested is typically low, but may range from 5% to as much as 35% depending on circumstances and type of iron. The efficiency with which iron is absorbed varies depending on the source.
Red meat is an obvious and effective way to boost iron levels, as it’s easily absorbed. A 4-ounce serving of ground beef , for example, packs 2.19 mg of iron, over 12% of the daily value.
White beans. There’s a reason beans are a go-to for plant-based eaters. One half-cup of white beans offers nearly 3.5 mg of iron, the USDA says, along with 8.7 grams (g) of protein and 5.6 g of ...

Roughly 5 grams of iron are present in the human body and is the most abundant trace metal. [1] It is absorbed in the intestine as heme or non-heme iron depending on the food source. Heme iron is derived from the digestion of hemoproteins in meat. [4] Non-heme iron is mainly derived from plants and exist as iron(II) or iron(III) ions. [4]
Iron absorption: According to food science consultant and author Bryan Quoc Le, most foods can benefit from being cooked in cast iron, since small amounts of iron are absorbed during cooking ...
One of these metabolites, butyrate, is important as an energy source for colon cells, and may improve metabolic syndrome. [ 40 ] [ 41 ] In 2016, the U.S. FDA approved a qualified health claim stating that resistant starch might reduce the risk of type 2 diabetes , but with qualifying language for product labels that only limited scientific ...
