Kale is also rich in antioxidants, including flavonoids and carotenoids, which help protect the body against oxidative stress and inflammation.

Blueberries are also a good source of fibre, vitamin C, and vitamin K, making them a delightful addition to any diet. Numerous studies have suggested that regular consumption of blueberries may contribute to improved brain function, cardiovascular health, and blood sugar regulation.
