Sweet Grapefruit Smoothie Recipe with Orange and Banana

Grapefruit Green SmoothieI found this smoothie recipe by accident the other day. I had a grapefruit on hand that needed to be eaten so I decided to use it in a smoothie! This smoothie blends banana with grapefruit so it does not require a sweetener.

This smoothie is creamy without adding extra water. Davy is not a fan of grapefruit but he enjoyed this smoothie.

The powerful antioxidants in grapefruits may lower risk for heart disease. A 12-week study at the Scripps Clinic in San Diego lead by Dr. Ken Fujioka showed that eating one half grapefruit before meals helped facilitate weight loss due to a compound in the fruit itself.

Grapefruits contain compounds that interfere with certain medications such as statin drugs like Lipitor and Zocor. If you are on any medications, please consult with your doctor or pharmacist before consuming grapefruit.

Grapefruit Smoothie Recipe

  • 1 grapefruit, peeled
  • 1 large orange, peeled
  • 1 banana, peeled

Give a squeeze to both the grapefruit and orange when you add them to your blender so that you have some free liquid to help blend. This worked fine in my blenderĀ (I use a Vitamix) without needing to add water. If you have difficulty blending this smoothie in your blender, add just a little bit of water or extra squeezed orange juice.

Blend on high until smooth. Makes about 16 to 20 ounces.

Grapefruits are cleansing and help with detox. They are also a rich source of vitamin C like oranges.

Make It Green

You can easily make this recipe a green smoothie by adding two cups of fresh, chopped leafy greens. Kale or even dandelion would be excellent in this smoothie and will dramatically increase the amount of calcium to 30% RDA as well as boosting vitamin A and K levels. Fresh baby spinach, Swiss chard or collard greens are also good choices and should not affect the flavor too much since the banana and citrus will do a good job of masking bitter greens.
