Summary

The purpose of this study is to assess the effects of consuming various lentil varieties in mixed-meals (containing either white rice or white potato) on post-prandial blood glucose and insulin as compared to white rice or white potato alone.

Detailed description

Eligible participants will undergo a total of 6 study visits. During each visit, a fasted blood sample will be taken by fingerprick, and approximately 500µL of blood will be dripped into a collection tube. The participant will then consume a meal of either: white bread, white rice (or white potato), or white rice with lentils (or white potato with lentils). White bread will be consumed on the first study visit and the rest of the meals will take place in random order in the visits following. Each meal will provide a total of 50g available carbohydrate. Six more blood samples will be taken by fingerprick at 15, 30, 45, 60, 90 and 120 minutes after the beginning of the meal.

Interventions

Type	Name	Description
OTHER	Various lentil varieties (varying in slow digested starch content)	Randomized, cross-over block design. Comparison of glycemic and insulinemic responses following meals composed of: * white rice or white rice combined with 1 of 3 different lentil varieties or * white potato or white potato combined with 1 of 3 different lentil varieties Participants with be assigned to either the white rice or white potato group. Meals will provide 50g available carbohydrate (AC). In meals containing lentils, whole cooked lentils will provide 25g AC either white rice or white potato will provide 25g AC. Meals will be randomly consumed across 6 study visits, with 2 white bread control meals (one of which will take place on the first visit).
