The human brain, an incredible powerhouse, operates tirelessly 24/7, even during sleep. Constituting only about 2% of our body weight, it astonishingly demands 20% of our daily energy intake. This constant demand highlights a critical truth: the quality of our thoughts, mood, memory, and even our risk of neurological diseases are deeply intertwined with the nutrition we provide. Simply put, our brain reflects what we eat.
Understanding the profound impact of diet on brain function is essential for optimal health. Diets high in saturated fats, refined carbohydrates, and excessive sugar, particularly from ultra-processed foods, can be detrimental. Such choices damage blood vessels in the brain, heightening the risk of impaired function, stroke, and dementia. They also hinder the brain’s ability to produce ATP, crucial for cellular energy. In contrast, a nutrient-rich diet—abundant in omega-3 fatty acids, antioxidants, B vitamins, and essential minerals—supports neurotransmitter levels, protects brain cells, and significantly enhances cognitive performance.
While reversing cognitive decline isn’t always possible, embracing a brain-healthy diet can markedly slow neurodegeneration and lower the risk of conditions like Alzheimer’s disease. What specific nutrients and foods does science champion for cognition, fighting mental fatigue, and maintaining a sharp mind as we age? We’ve gathered insights from leading experts, including Dr. Aaron Lord, chief of neurology at NYU Langone Hospital–Brooklyn, and registered dietitians Maggie Moon, Alma Simmons, Julie Duffy Dillon, and Lauren Harris-Pincus.
