This could be a gesture of confidence in the official, as with US President George W. Bush's refusal of his Secretary of Defense Donald Rumsfeld's twice-offered resignation during the Abu Ghraib prison abuse scandal.
There are two types: heme and nonheme. Heme iron is found in meat and fish, while nonheme is in certain leafy greens and iron-fortified grains, such as breakfast cereals. Meat eaters have an easier time getting their daily dose of iron because heme iron is more easily absorbed into the body. Thatâs why the Food and Nutrition Board at the National Academy of Sciences recommends that vegetarians consume nearly two times more iron each day than people who eat meat.
One boiled egg can reduce absorption of iron in a meal by as much as 28%. Oxalates impair the absorption of nonheme iron. Oxalates are compounds derived from oxalic acid and 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.
