Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Potato treatment
Participants will be provided with one potato-based side dish, equivalent to one medium sized potato, every day for 4 weeks for incorporation into their self-selected diet. The potato-based side dish will be prepared at the Penn State Metabolic Kitchen. The potato side dish will consist of commonly consumed potato-based sides in the U.S. and there will be limited inclusion of ingredients high in saturated fat, refined sugars or sodium. French fries will not be provided. The variety of potatoes will represent consumption patterns in the U.S. including white, russet, yellow and red potatoes.
Potato-based side dish
Daily consumption of a potato-based side dish equivalent to one medium size potato for 4 weeks
Refined grain treatment
Participants will be provided with a calorie-matched refined grain-based side dish every day for 4 weeks for incorporation into their self-selected diet. The refined grain-based side dishes will be prepared at the Penn State Metabolic Kitchen and ingredients high in saturated fat, refined sugar or sodium will not be used. These will be sides commonly eaten in the U.S. (e.g. pasta made with white flour and white rice, white bread rolls). During this treatment, participants will be told not to consume potatoes.
