Wheat that has more of a natural compound called gallic acid tends to absorb less arsenic — like the gallic acid is blocking arsenic from getting in, helping keep the grain safer to eat.

Assessing Cancer Risk from Wheat and Rice Based Diets in Arsenic Endemic Regions of the Middle Ganga Plain, India: Identification of Hotspots and Risk Reduction Strategies

Cross-Sectional Study

Human

Scientists found that wheat grains with more gallic acid (a natural compound) had less arsenic in them, suggesting gallic acid might help block arsenic from getting into the grain.

Similar Assertions

When wheat grows in soil with lots of arsenic, it makes more of certain natural chemicals (like benzoic and caffeic acid) that might help it deal with the poison—so the more arsenic it absorbs, the more of these chemicals it produces.
