The Claim
Higher plasma selenium levels are associated with elevated fasting blood glucose, fasting plasma insulin, and insulin resistance in Chinese women over 45 years old.
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 Chinese women over 45, higher levels of selenium in the blood are linked to higher fasting blood glucose, higher fasting insulin, and greater insulin resistance.
See the scientific wording
Higher plasma selenium levels are associated with elevated fasting blood glucose, fasting plasma insulin, and insulin resistance in Chinese women over 45 years old, indicating that increased selenium exposure may be linked to impaired glucose metabolism in this demographic.
Too much selenium increases a protein called selenoprotein P, which triggers chronic inflammation in the body. This inflammation blocks the signals that tell muscle, fat, and liver cells to take up sugar from the blood. As a result, sugar builds up in the bloodstream, and the pancreas pumps out more insulin to compensate, leading to high fasting sugar and insulin levels.
What the research says
1 studyIn Chinese women over 45, higher selenium levels in the blood were linked to higher blood sugar and insulin levels, which are signs the body is struggling to manage sugar properly. This suggests too much selenium might hurt metabolic health in this group.
