Pineapple Cucumber Smoothie Ingredients

  • Cucumber—I like to use a seedless cucumber in this recipe, and I leave the skin on for added fiber. You can also blend up any cucumber with the skin and seeds if you don’t mind sipping up an occasional seed!
  • Pineapple or Papaya—Personally, I love the sweet, tropical flavor of pineapple in this cucumber smoothie recipe. Pineapple is one of the naturally sweetest fruits, so you don’t even need to add any additional sweetener! I’ve also made this healthy smoothie with papaya, which is very juicy, creamy, and sweet like cantaloupe when ripe.
  • Avocado—A frozen avocado will add loads of luscious creaminess and satiating fats to your green smoothie! (Or, substitute with half of a frozen banana.)
  • Water—You’ll need some liquid in this recipe, but you could also use coconut water or milk of choice.
  • Spinach—A nutrient-packed way to make this green smoothie ultra-green! Add as little or as much as you’d like.
  • Dates—This is an optional addition for sweetness. Generally, I think this smoothie is sweet enough with the fruit alone, but taste it for yourself after blending and add 1-2 dates if needed.

Substitution & Addition Notes

  • Vegetables—For some variety, you can change up the veggies in this cucumber smoothie recipe. If you want to swap out the cucumber, try celery instead, or even iceberg lettuce. Instead of frozen avocado, use frozen banana to add some sweetness. And if spinach isn’t your favorite, swap it out for kale or arugula instead.
  • Fruit—Instead of pineapple or papaya, you could try any number of fruits in this green smoothie recipe! Mango, cantaloupe, kiwi, peaches, apricot, or strawberries would all be tasty choices.
  • Liquid—Water is the simplest choice, but you can also blend with coconut water, milk of choice, or a fruit juice.
  • Sweetener—If this cucumber smoothie isn’t sweet enough to your liking, add any sweetener you prefer. I like to blend in 1-2 dates, or you could add a tablespoon of maple syrup, honey, stevia, etc.
  • Nuts & Seeds—If desired, add some flavor, texture, and nutrients with your favorite nut butter, nuts like almonds or walnuts, or seeds like ground flax or chia seeds.

Health Benefits of Cucumber Smoothie

Although cucumbers are technically a fruit, they’re low in sugar and not so sweet in taste. Cucumbers are 95% water, making them a highly hydrating food source. And, they offer some essential nutrients like vitamin K for bone health, vitamin C for immune support, and potassium that aids in blood pressure control.

Combined with spinach, this cucumber smoothie recipe is bursting with vitamin K1—which supports bone health by helping us to absorb calcium from other foods. Plus, spinach also offers vitamin C, vitamin A, folate, and some iron. Most impressively, spinach has powerful anti-inflammatory benefits, with loads of antioxidants that can help reduce inflammation and fight cancer.

Tying all of these nutrients together is avocado: a powerhouse of monounsaturated fats, also known as healthy fats. Monounsaturated fats have anti-inflammatory effects on the body, helping to reduce damaging chronic inflammation. And, since many essential vitamins are fat-soluble, the fats in avocado actually help our bodies to absorb other nutrients that we eat!
