How harmful is phytic acid?

Answered on September 12, 2014

Let's say I eat a very fatty food and get 1500 mg of phytic acid from it within a few minutes. By how much will this much phytic acid decrease mineral absorption in my gut? Percentages would be helpful.

Also, let's say this is all I eat for 4 hours, and then I have another meal. How much phytic acid will remain from the previous meal that would bind up minerals from the new meal?

Saying that I ate a particular fatty food and got x amount of phytic acid DOES NOT imply that all fatty food has phytic acid, or that even any fatty food has it (it is framed as a hypothetical), or that I think that there is something wrong with any such fatty food that may contain phytic acid. I thought I should clarify this point for the mentally challenged among us.

interested to hear answers here myself, I don't think it's that harmful in small doses, having experimented on myself with oats.

Read Lucas Tafur.........the man is awesome

"From epidemiological data, foods with high phytate content are not associated with increased risks for several chronic diseases. As association doesnt means causation, we cannot conclude that whole-grains are healthy but we cant also conclude that whole-grains are unhealthy. With the increasing attention to paleolithic and similar diets, it is of utmost importance that all evidence is critically analyzed and reviewed. Making unsupported statements and cherry-picking data would only cause rejection by scientists. Dogma is not good in science."

Depends on what you are after, and how many nutrients you eat throughout the day. In and of itself phytic acid is also an antioxidant, although there are probably better antioxidant sources available.

Phytic acid binds to the vitamins and minerals you eat, so if you do not eat many vegetables it could easily be an issue. Wikipedia notes that in a developing country, where you are talking rice+beans with minimal fruit/veg/meat, it can be a significant contributor to health issues. In a first world diet that more depends on your nutrient composition.

Lab testing for nutrient characteristics with a known amount of phytic acid foods would tell you how it precisely works for you. Otherwise, bacteria in your intestines also exist to free nutrients and destroy the phytic acid. That is going to be a highly individual characteristic.

calcium, magnesium, iron, zinc, and niacin are what you are primarily losing in this process. So you could also check out how much of those you eat in general.

Phytic acid is a substance found primarily in grains, legumes, nuts, and seeds.

Why you're picking on fat is beyond me.
