One cup of blueberries a day can improve artery function, support the aging brain, and help regulate blood sugar in ways that go far beyond antioxidants A brand new solo episode of the FoundMyFitness podcast with Dr. Rhonda Patrick is out now She discusses: • One cup vs. half a cup for artery function • Memory benefits and links to lower dementia risk • Who may see greater blood sugar benefits • How blueberries may help relieve gut symptoms • Why bananas may blunt blueberry polyphenols And so much more Link in the next post

I want you to eat blueberries, just not with bananas (unless you really want to). In my new episode, I examine the evidence for blueberries' benefits on blood flow, brain aging, glucose regulation, gut health, inflammation, and exercise recovery. Blueberries improve the ability of arteries to relax and deliver blood to the brain, heart, and working muscles. They can improve insulin sensitivity and buffer the blood-sugar response to a calorie-rich meal. Human interventions have also demonstrated improved aspects of memory and cognition in older adults, while observational data link regular blueberry intake to slower cognitive decline. This isn’t simply an antioxidant story. Blueberry polyphenols act like biological signals, influencing nitric oxide, inflammation, gene expression, and possibly neuronal plasticity. I also revisit the controversial banana-smoothie question, and explain why I take a cautious approach when my goal is maximizing blueberry-polyphenol exposure. The full episode is out now on YouTube, Spotify, and Apple Podcasts. Enjoy!
