Nourish to Flourish - Good Food Good Mood is a book written for children who are five and onwards. Depending on the child's reading age and vocabulary, some children may require some assistance from an adult.
The book is a great introduction to the more widely discussed topic of food and nutrition and the impact it has on brain health, mood, memory, learning, cognition, and wellbeing. It introduces children to important science and nutrition-based concepts, and the clever rhyming throughout makes it a fun and entertaining read.
As a teacher, and someone who is trained to deliver content about mental health, mindfulness, and nutrition, I feel this is a perfect starting point and a good introduction to the topic of personal wellbeing.
