Minnesota Neuroscientist: New Research Explores The Connection Between Sugar Buildup and Memory Performance

Do you walk into a room and suddenly forget why you’re there? Or maybe you struggle to find the right words mid-conversation, feeling a heavy “fog” slowing your thoughts. For years, we’ve been told this is simply a normal part of getting older. But some researchers are now looking at another possible factor—an overlooked buildup of tiny “sugar-like crystals” that may interfere with how brain cells communicate, a bit like ice weighing down a tree branch.

Dr. Joshua Carr, a respected neuroscientist, began investigating this after a frightening moment involving his wife. His work points to a specific, widely used carbohydrate—often hidden in processed foods—that may encourage the brain to store more sugar than it should. Along the way, he also came across a simple “Egg Toast Recipe”—a morning breakfast routine he says supports the brain’s ability to clear those “crystal-like” deposits and maintain stronger connections over time.

This idea has been drawing attention and debate, and not everyone is talking about it the same way yet. Still, if you want the full explanation, this presentation walks through the research and shows how to use this easy morning routine as part of a brain-supportive approach—so you can stay sharp, independent, and confident for years to come.
