They could never ban Phytic Acid, otherwise Whole-grain cereals a source of Phytates and Inositol would have to be prescribed.
Especially if they found out that possibly two bowls of whole-grain a day, represented a significant amount of Inositol to benefit people, including depressives and OCD people.
However now people are saying have three bowls a day, in the same mould of 5 a day Fruit and Veg. Not that I think you need 3 a day, I only have 2. Fortived with B's and Iron of course.
