Donating blood is a noble act, as an individual has the potential to save up to three people's lives. It is important that the person should be in good health before giving blood. Donating blood is a safe process, but it can be made safer by following a few dietary changes. Since donating blood lowers the iron stores in the body, one should begin building up their iron intake several weeks before donating rather than just eating foods which are rich in iron, on the day of donation.
