Phytic acid (known as inositol hexakisphosphate (IP6), inositol polyphosphate, or phytate when in salt form), a saturated cyclic acid, is the principal storage form of phosphorus in many plant tissues, especially bran and seeds. Phytic acid can be found in most grains, seeds and beans. Rich sources of phytic acid are wheat bran and flaxseed (3 % phytic acid).

Phytic acid has been considered as an anti-nutritional component in cereals, seeds and beans. Research has traditionally focused on its structure that gives it the ability to bind minerals, proteins and starch, and the resulting lower absorption of these elements. However, recent research have shown that phytic acid has many health benefits. Phytic acid has antioxidant, anticancer, hypocholesterolemic and hypolipidemic effects.

Anticancer effect of phytic acid
In animal studies phytic acid showed a protective action in carcinogenesis. This action could be explained by its mineral chelating potential. Some studies suggest that phytic acid acts as anti-cancer agent by reversing the proliferative effects of carcinogens.

Beneficial for diabetic patients
Phytic acid may have health benefits for diabetes patients. It lowers blood glucose response by reducing the rate of starch digestion and slowing the gastric emptying.

Other effects
Phytic acid releases inositol that during digestion. Although inositol is not an essential nutrient it might reduce depressions. Studies also show that phytic acid may reduce inflammation.
