Sweet potato – one of your 5-a-day, and a useful source for many vitamins and minerals including: retinol needed for vision, growth, immune function and is a key antioxidant; thiamin for energy production; and vitamin C for protein and neurotransmitter synthesis, detoxification and acts as an antioxidant.

Tuna – high in protein and low in fat, tuna also provides selenium for immune function, vitamin B3 for energy utilisation, and phosphorus for bone structure and energy storage.

Spinach – providing vitamin K for cell signalling and vitamin A for eye function, as well as fibre for digestion.

Pepper – high in vitamin A and C, but also B6 to release energy and folate which helps DNA synthesis.

Greek yoghurt –  this mayo alternative not only makes the tuna taste AMAZING but also contributes towards your protein and calcium requirements. Calcium is essential for bone growth and maintenance.
