Iron Intake & Vitamin C

I'd like to invite you to vote in an important and relevant poll on the right that is linked to what nutritionist Pam Rosow spoke about during our meeting a couple of weeks ago.

As strength and power endurance athletes the transportation of oxygen is critical to performance - oxygen is transported through hemogloblin in the blood of which iron is a key component. Having an appropriate amount of iron in your diet is critical for athletic success. We also know that vitamin c plays a key role in allowing the absorption of non-heme (vegetable or supplement) iron into the bloodstream. Heme-iron from red meat , poultry, and fish is highly available without vitamin C.

"The key role of ascorbic acid for the absorption of dietary nonheme iron is generally accepted. The reasons for its action are twofold: (1) the prevention of the formation of insoluble and unabsorbable iron compounds and (2) the reduction of ferric to ferrous iron, which seems to be a requirement for the uptake of iron into the mucosal cells."

Heme-iron can be found in the following foods:
Beef, turkey, chicken, shrimp, sardines, shellfish, etc.

Non-heme iron can be found in breakfast cereal, cooked beans and lentils, canned beans, potatoes with skins, enriched pasta, and canned asparagus.

Again vote in the poll on the right and let's see if it is something that we should address as a team!
