> For example milk (calcium) prevents iron absorption, so you might say a person eats meats hence his diet is balanced and rich in iron but he will suffer from iron efficiency if too much milk is consumed Calcium can inhibit iron absorption, but not to this degree. A typical healthy individual will still be able to absorb iron from dairy products, because dairy products themselves contain iron. Where it becomes a problem is for people who are already anemic. Remember that the body doesn't need very much iron in the first place, since it's capable of recycling it. It only needs to replace the small amount that's lost in this cycle. And furthermore, the body's absorption of iron is already pretty inefficient, so the effects of naturally-occurring calcium in dairy aren't this extreme.
