Detailed Description
This is a 30-day randomized, controlled trial with 3 arms: 1) non-potato food (almonds), 2) standard white potato French fry, 3) standard white potato French fry with potential glycemia-modulating spice/seasoning mix added. Free-living study participants will be assigned to consume one of the 3 foods (calorie matched) each day for a 30-day period. Body composition (via dual energy x-ray absorptiometry; DXA), and blood chemistry will be assayed at baseline and study completion, along with a sub-sample of subjects participating in a meal-based tolerance tests at study completion.
