Iron deficiency can be prevented by eating a well-balanced diet that includes iron-rich foods. Iron from meat and seafood sources is better absorbed by the body. However, you can improve iron absorption from non-meat and non-seafood sources by consuming them together with foods and liquids rich in Vitamin C.
