Dark green leaves
They have a great strong flavour as well as boosting dopamine – the ‘happy hormone’ in our brain.

Apples, berries and bananas
All of these contain the antioxidant quercetin, believed to help the brain prevent dopamine loss.

Eggs
Rich in filling protein, they also contain the amino acids that help stimulate dopamine production.

Salmon
Oily fish contains omega-3 fatty acids, essential in preventing fatigue, memory problems and mood swings.

Cheese
This provides you with the amino acid tyrosine, which helps increase dopamine levels. Switch your Cheddar for cottage cheese, for a low-fat alternative.
