Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This intervention will take place in the nutrition and dietetics teaching laboratory at the University of Canberra. Participants will be provided with three evening meals per week for a four-week period. There will be two arms:
1. Intervention arm will receive meals that contain 100g of legumes e.g., spaghetti bolognaise made with legumes.
2. Control arm will receive an isocaloric meal without legumes.

Other than the meals provided, participants will continue with their habitual diet with no restrictions placed on consumption at any other time of the day.
All provided meals will be developed by an Accredited Practicing Dietitian with 3 years experience. Meals will be cooked on site at the University of Canberra in the teaching laboratory and will provide approximately 2000kJs per serve with an average of 2 serves of grains and protein and at least 3 serves of vegetables. All meals will be served as the evening meal on Tuesday, Wednesday and Thursday with participants able to eat as much as needed. Any meals only partially consumed will be recorded.
