Even for non-vegetarians, most iron in the Australian diet comes from plant foods rather than meat. Less than 20% of iron intake comes from meat and meat products and about 40% comes from cereals and cereal products.9 The same is true in the United Kingdom, where 45% of dietary iron comes from cereals and cereal products and less than 20% comes from meat and meat products.10 Iron-fortified cereals make an important contribution to iron intake in both vegetarian and non-vegetarian meal plans, particularly in energy-restricted diets.
the cereal in my diet alone should give me about 65% of the rdi for menstruating females, which itself is more than i ought to need...if i could absorb it.
