About this trial
The purpose of this study is to see how adding avocado to a breakfast meal affects blood sugar control and signals of hunger and fullness after eating.
The investigators will test the effects of 3 breakfast meals on blood sugar control and signals of hunger and fullness after eating:
1. Whole-wheat bread and strawberry jam 2. Whole-wheat bread, strawberry jam, and avocado 3. Whole-wheat bread and strawberry jam (meal enriched with fat and fiber to mimic that of an avocado)
Participants will undergo 3 test periods, each separated by a week. Each test period consists of one day with set meals that the investigators will provide (breakfast, lunch, and dinner), and then the next morning, participants will eat a breakfast meal and have blood drawn several times over 4 hours.
