How Overeating Sugar Shrinks Your Brain & The Unexpected Thing That Grows It

This episode is brought to you by Bon Charge and AquaTru. Dwindling memory is often seen as a normal part of aging. But just because it’s common doesn’t mean it’s normal. There’s a lot we can do to safeguard the memory center of our brain, and it’s never too late to start. Today on The Dhru Purohit Show, we’re revisiting one of our most talked-about moments with Dr. Majid Fotuhi. He unpacks how excess sugar from a highly refined, processed diet can accelerate aging and damage key organs, including the kidneys, liver, and brain. Dr. Fotuhi also highlights animal studies linking sugar to brain decline, the blood markers we should all be monitoring, and practical strategies to support brain growth. Finally, he shares why having a strong sense of purpose is one of the most powerful ways to protect brain health. Dr. Fotuhi is a neurologist specializing in memory, concussion, and successful aging. With over 30 years of teaching, clinical practice, and neuroscience research at Harvard Medical School and Johns Hopkins, he has developed a multidisciplinary program to help people of all ages improve memory and attention. The results of his program have been published in numerous scientific journals as well as in his three books.
