Snack idea Tuna and cucumber sandwich

Next time you feel like a snack, opt for a tasty and nutritious tuna and cucumber sammy. While cucumber, which is 95 per cent water, is great for keeping hydration levels up, the tuna is a good source of omega 3 essential fatty acids. Omega 3 helps keep your skin hydrated and prevent spots and wrinkles, and it supports brain function and heart health.
