Phytate/ Phytic Acid - "Malabsorption Agent"

What is phytic acid ?

Phytic Acid is the storage form for inositol (a B vitamin) and about 70% of the phosphorus in plant seeds – it is especially found in the outer hulls of grains, legumes, nuts, and seeds. Higher amounts are found in plants grown using high-phosphate fertilzers (typical ly used commercially) rather than natural compost.

Srivastava BN and others. Influence of Fertilizers and Manures on the Content of Phytin and Other Forms of Phosphorus in Wheat and Their Relation to Soil Phosphorus. Journal of the Indian Society of Soil Science. 1955 III:33-40.

It's molecule is basically an Inositol (B-vitamin) ringwith six phosphate groups attached (a snowflake-like molecule)


(Phytic acid, myoinositol hexaphosphate, IP6)

–   Phosphorus as a component of phytic acid is organic and indigestible - and if consumed, without first being broken down by phytase enzymes, it will pass out in the stool.

What is phytate ?

Phytate is phytic acid bound to a mineral – i.e. its minerally chelated form

Phytic acid can bind to minerals in grains, nuts, seeds and legumes and also to minerals in your digestive tract that you have consumed in other foods - unlike ruminants, humans are unable to break down phytic acid and if not broken down prior to consumption (using a suitable preparation method that produces phytase enzymes) it can cause several health issues related to nutrient availability/utilization when consumed on a regular basis:

Cause mineral malabsorption

Negatively impact utilization of protein and starch/carbohydrate

Interfere with lipid absorption.

However, consumed in moderation, phytic acid also confers some beneficial effects.
