    Why you will love this recipe: 

    • This is the best watermelon and banana smoothie! It is so refreshing and full of fruity flavour. 
    • It's so easy to make and comes together in just a few minutes. 
    • You only need 3 ingredients to make this fruit smoothie including watermelon, banana and milk.
    • This smoothie is healthy, and can easily be made dairy free, and vegan.
    • This is a watermelon banana smoothie without yogurt. 
    • You can easily add some protein powder to turn this into a watermelon banana protein smoothie.
    • This smoothie makes great leftovers and is perfect for meal prep. 
    • You can easily turn this into a watermelon banana smoothie bowl and add extra toppings such as nuts, shredded coconut or chocolate chips. 
    • If you love smoothies you will also love this lemonade smoothie or this Pina colada mocktail.

    Key ingredients and substitutions:

    Chopped banana and watermelon in white bowls and milk in a measuring cup.
    • Watermelon - is there anything more refreshing than fresh, ripe watermelon? Watermelon gives this watermelon smoothie such a nice sweet and refreshing flavour that blends so well with the banana. 
    • Banana - ripe banana helps add natural sweetness to this banana smoothie without having to use any added sugar or sweeteners. Be sure to use ripe, yellow bananas rather than unripe green ones. You can use either fresh or frozen ripe banana for this smoothie. 
    • Milk - I used full fat coconut milk to make this smoothie because it's so rich and creamy but you can use any type of milk that you like including dairy milk, almond milk, oat milk, cashew milk, soy milk etc. 

    Banana health benefits: 

    Bananas are a healthy, convenient, delicious, and inexpensive fresh fruit. They contain many essential nutrients, fiber and are high in antioxidants. One banana contains approximately 112 calories, 0 grams of fat, 1 gram of protein, 29 grams of carbohydrates, 3 grams of fiber, 12% of the daily value (DV) for vitamin C, 7% of the DV for riboflavin, 6% of the DV for folate, 5% of the DV for niacin, 11% of the DV for copper, 10% of the DV for potassium and 8% of the DV for magnesium. 

    Bananas have also been shown to support digestive health, help improve blood sugar, help with weight loss, improve cardiovascular health, decrease blood pressure, and can help with exercise recovery. 

    Watermelon health benefits:

    Watermelon is a healthy fruit that is low in calories, high in water content, vitamins and minerals, and antioxidants. It is high in vitamin C, vitamin A, potassium and magnesium and is a good source of citrulline, an amino acid that can improve exercise performance. It also contains many antioxidants including vitamin C, carotenoids, cucurbitacin E and lycopene. 

    In terms of health benefits, studies have shown that watermelon could have anti-cancer properties, could improve cardiovascular health, reduce inflammation and oxidative stress, may improve digestion, may help macular degeneration, can help with skin health, and may help relieve muscle pain.
