Detailed Description

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

Healthy men and women (ages 21 - 65 years) were recruited to take part in a randomized, placebo controlled crossover design study. Subjects were screened to determine their health status (e.g. height, weight, body mass index, blood pressure and medical history). Subjects were randomly assigned to a sequence of two treatments with two study periods. The treatments are frozen wild blueberries and a placebo developed to match calories and fiber of the frozen wild blueberries. The subjects were asked to avoid high polyphenol foods in their typical diet for 7 days and consume one of the two treatments as a dietary intervention. After the seventh day subjects consumed a test meal along with either the wild blueberry or placebo. Blood was collected to determine glucose and satiety hormone levels.
