We’re learning that the foods we eat have a profound impact on how we feel, think, and behave. In fact, our diet is increasingly being recognized for its role in brain and mental health. Nutrition and neuroscience go hand in hand in keeping our brains healthy as we age. We can use nutritional neuroscience to focus our diet throughout our different life stages, targeting the evolving demands on our brains during our twenties, thirties, forties, fifties, and beyond.
