Snack Types and Their Effects on Satiety, Glucose, and Insulin

This study is looking at how different snacks affect your feelings of fullness (satiety), blood sugar (glucose) levels, and insulin levels. Researchers want to compare pretzels, Brazil nuts, potato chips, mixed nuts, and white bread. They will measure these effects at different times after you eat the snack. You might be able to join if you are a healthy adult between 18 and 55 years old. You cannot participate if you smoke, are pregnant, take certain medications, or have allergies to nuts or gluten. The study aims to understand which snacks have a greater impact on these important health markers. The current recruitment status is unclear.
