Blueberries for Gut, Brain, and Cardiometabolic Health in Prediabetes

Study on blueberries' effects on gut, brain, and heart health in prediabetes.

Recruiting
45-65 years
Female
Phase N/A

This study aims to see if blueberries can help women with prediabetes. Prediabetes is when blood sugar levels are higher than normal, but not high enough to be diabetes. The study will look at how blueberries affect heart health, brain function, and gut bacteria. Participants will take 22 grams of freeze-dried blueberry powder daily for six weeks. The trial is randomized (participants are randomly assigned to groups) and placebo-controlled (some will receive a non-active substance to compare results). Researchers expect blueberries to improve blood sugar, blood pressure, memory, and gut bacteria.

  • The study lasts for six weeks with daily blueberry intake.
  • Participants must be women aged 45-65 with prediabetes.
  • Those with berry allergies or taking certain medications cannot join.

Women who are overweight, but not obese, and have no serious health issues may qualify. This study could show that blueberries are not just tasty but may also be beneficial for health. Participants can contribute to important research about diet and health while potentially improving their own well-being.
