Key finding
Fasting blood glucose decreased significantly (p < 0.05).
This study compared the effects of selenium-enriched eggs and zeaxanthin-enriched eggs on glycemic and lipid metabolism in patients with type 2 diabetes, finding significant reductions in fasting plasma glucose and triglycerides.

Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
This study compared the effects of selenium-enriched eggs and zeaxanthin-enriched eggs on glycemic and lipid metabolism in patients with type 2 diabetes, finding significant reductions in fasting plasma glucose and triglycerides.
Managing blood sugar and lipid levels is crucial for patients with type 2 diabetes to prevent complications. The findings suggest that incorporating selenium or zeaxanthin-enriched eggs into the diet may offer a simple and effective dietary intervention for improving metabolic health in this population.
Limited sample size may affect generalizability. Short duration of the study may not capture long-term effects. No significant difference in HbA1c between groups.
