Description

  • Artificial sweeteners are linked to faster memory loss and thinking decline, equal to 1.6 years of extra brain aging
  • People under 60 who consume the most low or no-calorie sweeteners face the steepest drop in verbal fluency and overall cognition, making midlife a key time to cut them out
  • Adults with diabetes are at even higher risk, with sharper declines in memory and global thinking skills when relying on artificial sweeteners and sugar substitutes
  • The harmful effects were consistent across years of testing, showing that continued use steadily chips away at brain function
  • You can protect your brain by eliminating artificial sweeteners, using natural options like fruit, honey, monk fruit, and dextrose, and focusing on foods that fuel steady energy
