The Claim
Brazilian adults who currently smoke have a significantly lower average daily selenium intake (7.77 μg/day less) compared to non-smokers and former smokers, indicating an association between tobacco use and reduced selenium consumption.
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 Brazil, people who currently smoke consume about 7.77 micrograms less selenium per day than those who have never smoked or have quit, suggesting their diet tends to include less selenium-rich foods.
See the scientific wording
Brazilian adults who smoke have significantly lower selenium intake than non-smokers or former smokers, with current smokers consuming 7.77 μg/day less on average, suggesting tobacco use is associated with poorer dietary patterns that reduce selenium consumption.
What the research says
1 studyThis study found that people in Brazil who eat healthier diets and have higher incomes tend to get more selenium, and since smokers often have worse diets, they probably get less selenium too.
