In healthy people eating balanced diets, phytic acid’s effects on mineral status is minimal and it doesn’t seem to cause nutrient deficiencies.
To argue that some plant foods are “unhealthy” because of their phytic acid content seems extreme.
Pytates are most often found in nuts, grains, legumes, and beans with a smaller amount in veggies. The benefits of eating veggies far outweighs any negative effects of phytic acid.
There are ways to reduce the phytate content if you so choose: Heating, soaking, fermenting, and adding vitamin C appear to help break down phytic acid.
