The Royals are known for following a healthy lifestyle and that obviously includes taking regular exercise and watching what they eat.

It's well known that the late Queen Elizabeth maintained a healthy diet throughout her life, preferring simple dishes with plenty of fruit and vegetables.

And it was recently reported how Queen Camilla has a fondness for a particularly healthy snack in the form of peas, which are rich in vitamins C and E, zinc, and other antioxidants.

The Princess of Wales has previously opened up about her love for superfoods, such as avocados and green smoothies, but there are a handful of other nutritious foods that the Princess of Wales enjoys on a daily basis. And, following her recent battle with cancer, she's sure to have stepped up her wellness regime.

The mum-of-three makes sure to include two particular vegetables in her breakfast each morning which are packed with protein and healthy vitamins.

She includes spinach and kale in her breakfast along with other healthy ingredients such as oats, avocados and spirulina.

Spinach is known for its many health benefits including stabilising blood glucose levels and improving bone health as well as being packed with iron, vitamins, protein and minerals.

Kale is also very similar in many ways as it is full of Vitamin A and Vitamin C which aids eye health, as well as a good immune system and cold prevention. The superfood can also keep your skin looking radiant and get rid of any scars or dark circles.

However, breakfast is not the only meal that Kate chooses to make as healthy as possible as she often enjoys a number of immune-boosting snacks throughout the day which carry many benefits.

The Princess of Wales is known for satisfying her hunger cravings with raw fruit and vegetables including immune-boosting goji berries.

She is also a fan of popcorn, which can be a brilliant and tasty-low calorie snack to keep you going between meals, as long as it's not coated in too much sugar.
