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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
See the scientific wording

What the research says
1 studyPeople 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.
