One boiled egg can reduce absorption of iron in a meal by as much as 28%. Oxalates impair the absorption of non-heme iron. Oxalates are found in foods such as spinach, kale, beets, nuts, chocolate, tea, wheat bran, rhubarb, strawberries and herbs such as oregano, basil and parsley. The presence of oxalates in spinach explains why the iron in spinach is not absorbed.
Heme iron comes from hemoglobin in red blood cells; therefore, only animal products contain heme iron. Plant foods supply non-heme iron, which has a different chemical structure. Non-heme is also the type added to iron-fortified foods and beverages. Your body absorbs heme iron more efficiently than non-heme iron. Consuming heme iron sources will improve your levels more quickly. The best sources are chicken liver, oysters and beef liver, which supply 11, 6 and 5 milligrams per serving, respectively. Chuck beef, dark turkey meat, ground beef and top sirloin also provide considerable amounts of iron.
