1. Swap onions for courgettesWhy? Courgettes are a brilliant source of vitamin C4, which is vital for healthy skin and bones, and for wound healing.5 How? Whenever a recipe calls for a chopped onion to be softened in a pan, use a courgette instead; it adds a fresher flavour than onions and packs a nutritious punch. Try softening chopped courgette, then add crushed garlic and chopped tomatoes for an easy pasta sauce.
2. Make lettuce leaf tortillasWhy? According to a 2014 study in the US by the Centres for Disease Control and Prevention, iceberg lettuce is packed with nutrients such as potassium, folate and zinc.6 Potassium helps your heart function properly*, folate is needed for healthy red blood cells11, while zinc is crucial for cell and enzyme renewal.* How? Ditch your usual lunchtime wrap in favour of nature’s tortilla. Fill a large iceberg lettuce leaf with your favourite fillings such as falafels, add lots of extra veg like sweetcorn or shredded carrot, then sprinkle over a dressing or flavour-boosting herbs, wrap up and enjoy.
3. Bake a spinach cake (yes, really!)Why? Popeye’s favourite foodstuff is great for your heart health. A 2015 study published in the journal Clinical Nutrition Research revealed the high-nitrate content of spinach can help keep your arteries flexible, reducing blood pressure.7 How? We know courgettes and carrots work well in cakes, but spinach is also a winner in baking. It’s used in a traditional Turkish sponge cake – just wilt baby spinach and puree with vegetable oil, lemon juice and zest before adding to the ingredients of a regular sponge. The cake is then topped with mascarpone icing and pomegranate seeds. Healthy and delicious!

Pimp your smoothie with kaleWhy? This leafy green vegetable is rich in nutrients such as vitamins K, A and B68. Vitamin K is needed for blood clotting9, vitamin A is essential to a healthy immune system10, while vitamin B6 helps your body to use and store energy from protein and carbohydrates in the food you eat.11 How? For a revitalising morning drink that ups your vitamin intake, blend frozen kale and frozen mango with grated fresh ginger and lemon juice. Vary your smoothie by adding berries for even more nutrients, or a splash of coconut water or almond milk for a different consistency.

5. Boost your broccoli leftoversWhy? A 2018 study by the University of Western Australia found that eating cruciferous vegetables like broccoli is linked to keeping your arteries clear, which in turn protects your heart health.12 Steamed broccoli is best, according to a 2014 study published in the journal Plant Foods For Human Nutrition**, where researchers found that it actually increased its nutritional benefits. How? Got some broccoli leftover from Sunday lunch? Try these tips:
- whizz it up in a food processor and add to homemade fish cakes
- chop into small pieces and make broccoli and cheese fritters
- add to a pasta bake with plenty of other veggies – the Australian study also looked at legumes, leafy veg and coloured peppers
