What's the difference between iron and protein? I thought if I ate a lot of protein, I would also get a lot of iron although I've noticed that isn't necessarily the case. And I want to make sure to get enough iron b/c I'm borderline anemic.
red meat and dark green vegetables are good sources of iron.
Google "iron rich foods" for a good list.
Your body needs Vitamin C in order to absorb the iron from your food so match them up with vitamin C-rich foods e.g. orange juice, kiwifruit.
And caffeine limits the absorption of iron. So avoid coffee and cola drinks at the same time.
For iron, there's a lot of cereals that have 45% or more iron. (They're iron enriched.) So for breakfast, eat a good iron cereal and drink some orange juice. It's a great way to get 50%+ of your iron at the start of the day. (This is what I do on the mornings before I give blood and it works well.)
