A surprisingly stunning combination, grapefruit and fennel are both rich in vitamin C, phytonutrients, antioxidants, and potassium. The blend serves up anti-inflammatory, anti-cancer, weight-loss, and detox power that helps boost immunity, scavenge harmful free radicals, cleanse the colon, regulate heart rate and blood pressure, aid digestion, and alleviate stomach ailments.

Serves 2

1/2 cup (120ml) water

1/2 small fennel bulb, cored, trimmed of stalks, and chopped

1 medium red grapefruit, peel and pith removed, seeded, and cut into chunks

1 green apple, skin on, cored and chopped

1/4 medium avocado, pitted and peeled

1 1/2 tablespoons freshly squeezed lemon juice

15 drops alcohol-free liquid stevia, plus more to taste

1 1/2 cups (190g) ice cubes

Throw all of the ingredients (except the ice cubes) into your blender and blast on high for 30 to 60 seconds, until smooth and creamy. Add the ice and blast for a few seconds more, until smooth and chilled.

Boosters

1 cup (27g) loosely packed baby spinach

1 teaspoon flaxseed oil

1 teaspoon pomegranate powder
