Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Mixed Berry Diet
Participants will receive between 400 to 800 grams of mixed berries daily, as a proportion of their daily caloric intake added to their base diet. The base diet will be prepared using traditional American foods with a macronutrient composition representative of a typical American diet.
Mixed Berry Diet
Mixed Berry Treatment
Carbohydrate Control Jello
Participants will receive between 400 to 800 grams of strawberry jello daily, as a proportion of their daily caloric intake added to their base diet. The jello will be matched to the mixed berries in both total carbohydrate level and gram quantity. The base diet will be prepared using traditional American foods with a macronutrient composition representative of a typical American diet.
Carbohydrate Control Jello
Carbohydrate Control
Fiber Enriched Jello
Participants will receive between 400 to 800 grams of fiber enriched strawberry jello daily, as a proportion of their daily caloric intake added to their base diet. The jello will be matched to the mixed berries in both total carbohydrate level and fiber content, and in the same gram quantity. The base diet will be prepared using traditional American foods with a macronutrient composition representative of a typical American diet.
Fiber Enriched Jello
Fiber Control
Low Fiber Mixed Berry Juice
Participants will receive 1 liter per day of low fiber mixed berry juice added to their base diet. The juice will be squeezed from the mixed berries, then filtered. The sugar level of the juice will match that of the mixed berries. The base diet will be prepared using traditional American foods with a macronutrient composition representative of a typical American diet.
