The Claim

Higher grain consumption is associated with lower serum selenium levels in healthy adults from Galicia, Spain, with an odds ratio of 0.992 per unit increase in grain intake (p=0.036), potentially due to phytate-mediated inhibition of selenium absorption.

In plain English

In healthy adults from Galicia, Spain, eating more grains is linked to slightly lower levels of selenium in the blood, possibly because compounds in grains interfere with selenium absorption.

What the research says

1 study
  1. Study: Associations between food group intake and serum levels of selenium and other essential and toxic trace elements in adults

    People in Spain who ate more grains had slightly lower levels of selenium in their blood, which matches what the claim says. This might be because grains contain substances that block selenium absorption.
