The Claim
Among Vietnamese adults, dietary selenium intake in the range of 27.8–77.2 µg/day is associated with a 3.78-fold higher odds of developing cancer compared to intake in the range of 110.8–124.4 µg/day.
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.
Vietnamese adults with the lowest selenium intake have 3.78 times higher odds of developing cancer than those with higher selenium intake.
See the scientific wording
Among Vietnamese adults, the lowest dietary selenium intake (27.8–77.2 µg/day) is associated with a 3.78-fold higher odds of developing cancer compared to those consuming 110.8–124.4 µg/day, suggesting that selenium deficiency may be a significant risk factor in this population.
When selenium levels are too low, the body cannot make enough proteins that protect DNA from damage and fix broken DNA. This lets harmful mutations build up in cells, which can cause cells to grow uncontrollably and turn into cancer.
What the research says
1 studyStudy: A U-shaped association between selenium intake and cancer risk
Vietnamese adults who ate very little selenium were nearly four times more likely to get cancer than those who ate just the right amount, showing that not getting enough selenium may increase cancer risk.
