Phytic acid in grains, nuts, seeds and beans represents a serious problem in our diets. This problem exists because we have lost touch with our ancestral heritage of food preparation. Instead we listen to food gurus and ivory tower theorists who promote the consumption of raw and unprocessed “whole foods;” or, we eat a lot of high-phytate foods like commercial whole wheat bread and all-bran breakfast cereals. But raw is definitely not Nature’s way for grains, nuts, seeds and beans. . . and even some tubers, like yams; nor are quick cooking or rapid heat processes like extrusion.
Phytic acid is the principal storage form of phosphorus in many plant tissues, especially the bran portion of grains and other seeds. It contains the mineral phosphorus tightly bound in a snowflake-like molecule. In humans and animals with one stomach, the phosphorus is not readily bioavailable. In addition to blocking phosphorus availability, the “arms” of the phytic acid molecule readily bind with other minerals, such as calcium, magnesium, iron and zinc, making them unavailable as well. In this form, the compound is referred to as phytate."
