Question

The absorption of this mineral is decreased when the diet is high in fiber and phytates.

Answer 1

The absorption of iron is reduced when you have a diet high in fiber and phytates. Even though an excess of fiber can have an effect in the body’s ability to absorb some minerals, fiber is very safe and even necessary in reasonable amounts. phytatic acids on the other hand are responsible of binding metallic cations reducing the capacity of the body of absorbing iron, calcium and zinc and should be consumed with moderation.
