Take into account that whole grains have considerably higher mineral content
than refined grains. That is why you can in a sense afford the less
efficient absorption of minerals.

The effect of phytates is not only adverse. They also have a beneficial role
in prevention of diseases like cancer and cardiovascular diseases.

I wouldn't be too concerned of phytates. If you want to reduce phytates it
can be done by soaking grains. In baking the sourdough process reduces
phytates very efficiently.

Hi
I'd like to know what scientific studies say about phytic acid in food
I know that it's "thought" that foods containing phytates may interfer
with calcium, zin, iron absorption and certain groups (westonaprice
foundation) have created an hype attacking all foods that contain
phytates but what I saw on pubmed is

1) theoretical third world epidemiological studies that theorize that a
whole grain and legume diet may cause mineral deficiency

2) studies on animals that have nothing to do with humans

3) studies on humans using isolated phytic acid in high concentration

What I want to know is wether there's any amount of scientific evidence
that a varied diet adequate in mineral intake containing two or more
portions of legumes and/or whole grains can lower mineral the
absorption of minerals in any relevant way or even cause mineral
deficiencies

Thanks
