Nutritional psychiatry is an idea whose time has come. That raises a question: What took the medical profession so long to embrace it?

Among global leaders of nutritional psychiatry is US psychiatrist Dr Georgia Ede. In a recent article in Psychology Today, Ede explores optimum nutrition for mental health. She looks at why we humans can’t thrive on plants alone and why our brains must have animal fats for optimum functioning.

Dietary fat is not just for insulation and energy storage, Ede writes. It’s also for “nutrient absorption, cell signalling, immune function, and many other critical processes”.
