The Claim
Among Vietnamese adults, dietary selenium intake in the range of 169.1–331.7 µg/day is associated with an 86% higher odds of developing cancer compared to intake 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 who consume the highest amounts of selenium in their diet have 86% higher odds of developing cancer than those who consume lower amounts.
See the scientific wording
Among Vietnamese adults, the highest dietary selenium intake (169.1–331.7 µg/day) is associated with an 86% higher odds of developing cancer compared to those consuming 110.8–124.4 µg/day, suggesting that excessive selenium intake may also increase cancer risk.
Too much selenium overwhelms the body's ability to manage reactive molecules, causing damage to DNA and blocking the systems that fix it, which allows errors to build up and turn cells cancerous.
What the research says
1 studyStudy: A U-shaped association between selenium intake and cancer risk
Vietnamese adults who ate a lot of selenium had almost twice the chance of getting cancer compared to those who ate just the right amount, showing that too much selenium can be harmful.
