The Claim
Children living in a coal mining area in Candiota, Brazil, have significantly higher dietary selenium intake and urinary selenium excretion than children in a nearby non-mining control city, while both groups maintain selenium levels within normal physiological ranges and exhibit low prevalence of selenium toxicity symptoms.
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.
Children in a coal mining area of Brazil consume more selenium in their diet and excrete more selenium in their urine than children in a nearby non-mining city, but both groups have selenium levels within the normal range and show few signs of selenium toxicity.
See the scientific wording
Children living in a coal mining area in Candiota, Brazil, exhibit significantly higher dietary selenium intake and urinary selenium excretion compared to children in a nearby non-mining control city, despite both groups maintaining levels within normal physiological ranges and showing low prevalence of selenium toxicity symptoms.
Burning coal releases selenium into the air and soil, which gets absorbed by plants and water sources. Children eat these plants and drink this water, so they take in more selenium. Their bodies process the extra selenium and remove the excess through urine, but they do not get sick because the amount stays within safe limits.
What the research says
1 studyKids living near coal mines in Brazil had more selenium in their food and pee than kids in nearby towns, but both groups had safe, normal levels and didn't get sick from it.
