You feel how you eat. We accept that the quality of our diet affects the health of our heart and liver. So why wouldn't diet good or bad affect the health of our brain? This is the question that Australian scientist Felice Jacka set out to answer. Having suffered depression and anxiety as a young woman, she wanted to understand the role diet plays in our overall mental and brain health. What she found through her own research and that of other eminent scientists worldwide will revolutionise the way we think about what we eat and how we care for our brains.
