This research study will compare participants consuming a powdered strawberry supplement to a strawberry-flavored placebo powder over a 3-month period to determine the health effects of consuming a strawberry supplement on mobility and memory in older adults. Specifically, we are looking for individuals who have been told “to watch their sugar intake,” or
that they are “pre-diabetic,” “insulin resistant,” or have elevated blood sugar (or hemoglobin A1C) levels but are not taking metformin or any other medications for diabetes to participate in this research study.
