In plain English

In healthy adults from Galicia, Spain, people who consume more dietary oil tend to have lower levels of selenium in their blood, which may be related to how fat in the diet affects selenium absorption or reflects broader dietary habits.

See the scientific wording

Higher intake of oil is associated with lower serum selenium levels in healthy adults from Galicia, Spain, with an odds ratio of 0.947 per unit increase in oil consumption (p=0.018), suggesting dietary fat may impair selenium bioavailability or reflect an overall dietary pattern that reduces selenium status.

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 the study who ate more oil tended to have lower levels of selenium in their blood, which means eating lots of oil might make it harder for the body to keep enough selenium, a helpful mineral.
