What you say makes so much sense to me. After eating a healthy meal like tuna and salad, I feel really good afterwards. This sounds silly but it’s like the body is saying thank you. It is more than psychological, it’s a physical thing. I feel energised and happy. Likewise if I eat too many crisps or sweets, about an hour later I feel really low and can’t think as clearly.

The Happy Kitchen sounds really interesting and a good idea.
