The Claim

Glutathione peroxidase 3 is not significantly associated with insulin resistance or glycated hemoglobin in Chinese women over 45, and exhibits only a weak association with fasting blood glucose, indicating it is not a major contributor to selenium-related metabolic dysfunction in this population.

In plain English

In Chinese women over 45, levels of glutathione peroxidase 3 show no meaningful link to insulin resistance or glycated hemoglobin, and only a weak link to fasting blood glucose, suggesting it does not play a major role in selenium-related metabolic changes.

See the scientific wording

Glutathione peroxidase 3 shows no significant association with insulin resistance or glycated hemoglobin in Chinese women over 45, and only a weak association with fasting blood glucose, suggesting it may not be a major contributor to selenium-related metabolic dysfunction in this group.

Why this might work

High levels of a selenium-containing protein trigger chronic inflammation in the liver, muscle, and fat tissue. This inflammation blocks the body's ability to respond to insulin, causing blood sugar to rise. Glutathione peroxidase 3 does not play a major role in this process, so it shows little connection to long-term blood sugar control or insulin resistance.

  1. Study: Inflammation Mediates the Associations Between Selenium Status and Glucose Metabolism in Chinese Females Over 45 Years Old: a National Cross-Sectional Study.

    In older Chinese women, the study found that a selenium-related enzyme called GPx3 is only weakly tied to fasting blood sugar and not linked at all to long-term sugar control or insulin resistance — just like the claim says.
