The Healthiest Smoothie Orders at Jamba Juice, Robeks, and Planet Smoothie

Check out these nutritionist-approved picks—plus how to make even healthier versions at home.

There's no doubt about it: the smoothie trend is here to stay. Many of my clients drink one every day; and some even prefer an icy blend to eating a solid meal. The only trouble is, there’s no standard smoothie formula—so the nutritional quality of these drinks can vary wildly. If you’re not careful, you could easily sip several spoonfuls of added sugar, or consume a day's worth of calories(!) in a single serving. To make sure you're getting a good mix of healthy ingredients, stick with these RD-approved orders at Jamba Juice, Robeks, and Planet Smoothie. And to healthy up your beverage even more, check out my recipes for versions you can whip up at home.

Jamba Juice

Choose the Tropical Greens

I love that it's made with clean, simple ingredients: just fresh apple juice, pineapple, spinach, kale, chia seeds, and ice, with no added sugar. A 12-ounce serving contains 160 calories, 1.5 grams of fat, 35 grams of carb, with 4 grams as fiber, and 3 grams of protein.

DIY version: To round out the macronutrient balance and bump up the fiber in this smoothie, blend a small whole cored green apple with a half cup of frozen pineapple, a half cup each of fresh spinach and kale, a quarter of a ripe avocado, a tablespoon of chia seeds, one scoop of plant-based protein powder (I personally like Naked Pea vanilla), ice, and enough water to create your preferred consistency. To further boost the smoothie's antioxidants and anti-inflammatory power, toss in a one-inch cube of fresh peeled ginger root. Yes, the numbers go up, but it’s now a complete meal you can enjoy for breakfast, or as a post-workout recovery drink. New stats: 330 calories, 11 grams of fat, 44 grams of carb with 13 grams as fiber, and 18.5 grams of protein.

Get the Chocolate Chimp for a chocolate fix

Sometimes a decadent smoothie can satisfy your sweet tooth and keep you from ordering a milkshake, or devouring a pint of ice cream.
