Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized, clinical trial will be performed to assess changes in body weight and fat mass with daily potato consumption versus a calorie-matched snack of almonds.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

White potato (French fries)

Participants will be asked to consume 1 serving of French fries each day for 30 days.

Group Type EXPERIMENTAL

White potato (french fries)

Intervention Type OTHER

If randomized to this group, participants will be asked to consume 1 serving of French fries (\~300 kcal) each day for 30 days as a part of their usual dietary intake. French fries will be portioned and provided to participants.

White potato (French fries), +seasoning

Participants will be asked to consume 1 serving of French fries with added seasoning each day for 30 days.

Group Type EXPERIMENTAL

White potato (French fries), +seasoning

Intervention Type OTHER

If randomized to this group, participants will be asked to consume 1 serving of French fries (\~300 kcal) with added potential glycemia modifying seasoning mix each day for 30 days as a part of their usual dietary intake. French fries and seasoning will be portioned and provided to participants.

Almond

Participants will be asked to consume 1 serving of almonds (calorie-matched to other arms) day for 30 days.

Group Type ACTIVE_COMPARATOR

Almond

Intervention Type OTHER

If randomized to this group, participants will be asked to consume 1 serving of almonds that is calorically-matched to the French fries (\~300 kcal) serving in the other arms each day for 30 days as a part of their usual dietary intake. Almonds will be portioned and provided to participants.
