Yet the focus of most diets is on the way we look rather than the way we think. To put it simply, the human brain is made of food. In the long term, this affects every one of us, because food affects not just our moods and thoughts but also the way we age. The brain is so sensitive to dehydration that even a minimal loss of water can cause symptoms such as brain fog, fatigue, dizziness, confusion and, more importantly, brain shrinkage. • Lisa Mosconi is the author of Brain Food: How to Eat Smart and Sharpen Your Mind, published by Penguin Life at £14.99
