Detox Island Green Smoothie Nutrition Facts

These are the cafe’s published values for the standard 24-ounce smoothie. Recipes and sizes can change, so check the current guide or ask at your local cafe if you track nutrition closely.

The guide does not list the smoothie’s ingredients, so the homemade version below is our own copycat built from spinach, kale, mango, pineapple, banana, and fresh ginger. Its nutrition will differ from the cafe’s numbers depending on your fruit, portion, and liquid.

What the Numbers Mean

• Calories: 210 calories for 24 ounces is modest for a fruit smoothie, because greens and water-rich fruit make up much of the volume.
• Sugar: 39 grams is a lot of sugar in one drink, even when all of it comes from fruit. The FDA’s 50-gram Daily Value applies to added sugars, which this smoothie does not contain according to the cafe, but the total is still worth knowing if you watch carbohydrates.
• Protein and fat: with 4 grams of protein and 1 gram of fat, it is a fruit drink rather than a full meal. Many people pair it with something that has protein.

Does the “Detox” Smoothie Actually Detox?

“Detox” is part of the menu name, not a measurable effect. The U.S. National Center for Complementary and Integrative Health reports there is no compelling evidence that detox drinks or programs remove toxins from the body. What this smoothie does offer is a real serving of fruit and leafy greens in a form that is easy to drink. That is a good reason to enjoy it; cleansing is not.

How to Make a Detox Island Green Copycat at Home

Each ingredient has a job. Knowing what it does makes it easy to adjust the smoothie to what you have.

• Frozen mango and pineapple chill and thicken the smoothie, so you do not need ice, which would water it down. Pineapple adds the bright, tangy note that keeps the greens from tasting grassy.
• Banana brings sweetness and a creamy texture. A frozen banana makes it thicker and colder.
• Spinach has a mild flavor and disappears into the fruit. Kale is more assertive; remove the tough center stems so they do not leave fibrous bits.
• Fresh ginger adds a little heat. Start with half a teaspoon, grated, and add more next time if you like it.
• Unsweetened almond milk keeps the flavor neutral. Coconut water makes it more tropical and lighter; any milk works.

Blending Tips for a Smooth Green Smoothie

• Liquid first, frozen fruit last. Liquid at the bottom keeps the blades moving; greens in the middle get pulled down and broken up before the frozen fruit goes in.
• Watch for the cue. It is ready when it is an even green with no visible flecks of leaf and pours slowly but steadily.
• Too thick? Add liquid 2 tablespoons at a time. Too thin? Add a few more frozen mango chunks.

Easy Swaps

• Less sugar: replace the banana with 1/4 avocado for creaminess, and use a little more greens.
• More protein: add a scoop of protein powder or a tablespoon of nut butter, then add a splash more liquid.
• No kale: use all spinach; the smoothie will taste milder and sweeter.

Looking for something richer? Try this acai smoothie bowl or a chocolate smoothie. For a no-blender option, fennel infused water and orange and fennel water are light, fruity alternatives.

Storing and Prepping Ahead

This smoothie is best right after blending. If it sits, it separates and thins out as the frozen fruit melts; stir or shake it before drinking, and keep it covered in the refrigerator if you are not drinking it right away. To save time in the morning, portion the greens, frozen fruit, and ginger into freezer bags, then blend a bag with the liquid when you need it.

Who Should Be Careful

• People taking warfarin (Coumadin). Leafy greens are a source of vitamin K. The NIH Office of Dietary Supplements advises keeping your vitamin K intake about the same every day while on warfarin, so talk to your doctor before making a daily green smoothie a new habit.
• People told to limit oxalate. Spinach is a high-oxalate food. If you have been advised to follow a low-oxalate diet for kidney stones, follow your care team’s guidance on greens.
• Anyone watching carbohydrates. Check the sugar numbers above and adjust the fruit to fit your needs.
