1. Beef Liver. Beef is one of the most famous foods rich in iron. It is the first recommended food for people to eat when they are deficient.

One boiled egg can reduce absorption of iron in a meal by as much as 28%. Oxalates impair the absorption of non-heme iron.

The presence of oxalates in spinach explains why the iron in spinach is not absorbed.
