Summary

This study looked at how eating ultra-processed foods (like packaged snacks and sugary drinks) affects gut bacteria and blood sugar control in adults aged 45 to 65. Twenty healthy but sedentary participants ate either a high or low ultra-processed diet for six weeks. Researchers measured insulin sensitivity and 24-hour glucose levels to see if these foods harm blood sugar regulation, possibly leading to type 2 diabetes.
