Seeds — such as nuts, edible seeds, beans/legumes, and grains — store phosphorus as phytic acid. When Phytic acid is bound to a mineral in the seed, it’s known as Phytate.
Phytic acid is similar in some ways to a vitamin, and metabolites of Phytic acid may have secondary messenger roles in cells.
When Phytic acid binds minerals in the gut, it prevents the formation of free radicals, thus making it an anti-oxidant. Phytic acid also stimulates the immune system.
