When we think of vitamin C-rich foods, we often think of oranges - an average sized one will yield around 70mg of the vitamin, with a small one offering around 51mg.

But it's a good idea to keep your diet varied and luckily the vitamin is found in plentiful amounts in many other common fruits and veggies too.

Here are a few other fridge and fruit bowl staples to keep in mind on your next trip to the supermarket. And each of them contains more vitamin C per 100g than oranges.

1. Broccoli

This fibrous, branched staple of the Sunday roast dinner doesn't just taste great, it's also a nutrient-rich powerhouse in the cruciferous vegetable family. While 100g of oranges contain roughly 53mg of vitamin C, the same weight of broccoli yields around 89mg.

As well being a great pairing with your roast lamb, broccoli is perfect for a quick stir fry with other vegetables. "I recommend including mange tout, baby sweetcorn, thinly sliced courgettes and button mushrooms," says Dr Emma Derbyshire, nutritionist for the Health & Food Supplements Information Service (HSIS.org). "When it comes to a healthy diet, think about cooking a rainbow."

2. Red pepper

Red pepper offers around 128mg of vitamin C per 100g, which is pretty impressive - and this fabulous fruit is also a great source of vitamins A, E and K, which support eye, nerve and bone health respectively.

"Red peppers are great in stir fries, but I also like to cook them as part of a roast vegetable mix," Derbyshire recommends. "Try chopping them up and roasting them in the oven with butternut squash and red onion. They're also super tasty when stuffed with a herby breadcrumb mix and baked in the oven."

3. Kiwi fruit

The tangy and flavourful kiwi fruit isn't to everyone's taste, but if you're a fan, there's a good reason to keep adding these juicy green spheres into your fruit salads.

In 100g of kiwi, you'll find around 93mg of vitamin C, and eating just one of these little beauties delivers around 64mg. They offer vitamin K, vitamin E, folate, and potassium too, and also contain a good amount of disease fighting antioxidants.

"If you're getting bored of just eating kiwi fruit straight out of its skin, try putting it in a smoothie. Blend together either milk or a plant-based alternative, with a satsuma, banana, a spoonful of live yogurt (which is a probiotic) and a teaspoon of cinnamon for extra sweetness," suggests Derbyshire.

Let's face it though, even during the lockdown, we're all busy people and it's not always easy to plan out your meals if you are waiting for a food delivery. If you feel your diet isn't quite cutting it, try Holland and Barrett vitamin C with wild rose hips tablets (£10.99 for 100 capsules, hollandandbarret.com) for an extra springtime boost.
