It's been tipped as a superfood that deserves a permanent space in your kitchen, and with kale smoothies, salads and even kale chips taking centre stage in the world of healthy eating, it's little wonder this veggie has gained such popularity. But why exactly should we be munching on the green stuff? Read on to find out five great reasons why kale should be a staple in your diet. 

1. It has more vitamin C than an orange

One cup of chopped up kale (about 70g) has 134% of your recommended daily allowance (RDA) of vitamin C. Compare this to a medium sized orange that only has 113% of your daily RDA and you'll soon see why kale is the veggie to turn to for a vitamin C boost. 

2. It's high in fibre and low in fat 

One serving of kale will only set you back 36 calories, with a whopping 5g of fiber and 0g of fat. That makes it the perfect green to aid your digestion and expel toxins

3. It's filled with cancer-fighting vitamin K 

According to research in the American Journal of Clinical Nutrition, eating a diet rich in vitamin K, which is a rich antioxidant can help reduce your overall risk of developing cancer. Kale has a very high level of vitamin K, similar to other leafy greens such as parsley and spinach. Other research has found that vitamin K can help prevent blood clotting, maintain bone health and help treat Alzheimer's disease. 

4. It's calcium-rich for healthy bones

Per calorie, kale has more calcium than milk. And calcium isn't just for children with growing bones, in fact boosting your calcium intake can help prevent bone mass loss and osteoporosis and maintain a healthy metabolism. 

5. It's easy to prepare 

There are so many delicious recipes available for kale. It can be steamed for pastas and salads, baked to created crunchy 'chips', stir fried or added to soups and casseroles for an added nutrient boost. And with so many options to integrate it into your diet, you have no excuse not to try it out the next time you're in the supermarket.
