A smoothie is a thick beverage served cold that’s most commonly made with a mixture of fruits and vegetables. It usually starts with a liquid base like water, dairy or plant milk, and all the ingredients are pureed in a blender. Common Ingredients There are hundreds of smoothie recipes, each with a different mix of ingredients. Here, though, are some of the popular ones: Leafy greensGreen vegetables like cucumbers, sprouts and celeryFresh and frozen fruits like berries, mango, pineapple, apples, bananas, oranges, pomegranates, cherries, kiwi, watermelon, coconut and pearsVegetables like carrots, beets and cauliflowerAvocadosCacao and cacao nibsOatsNutsYogurt, dairy and plant-basedMilk, dairy and plant-basedNut butters like peanut and almond butterTahiniSeeds like chia, flax and hempSpices like fresh ginger root, cinnamon and turmericFruit juices like apple and cranberrySweeteners like honey, dates, maple syrup and steviaMatchaCrushed ice Types of Smoothies Photographer: Brie Passano, Food Stylist: Annie Probst, Prop Stylist: Holly Raibikis Pictured Recipe: Creamy Strawberry Smoothie Because of the plethora of ingredients you can throw into a smoothie, you can make thousands of different smoothies. Yet, most smoothies fall into one of the following three categories: Green Smoothies: You’ll find at least one leafy green in these smoothies—think spinach, kale or arugula—along with other nutrient-rich fruits and vegetables to take away the bitter taste of the greens. Those fruits and veggies are often green, too, so don’t be surprised if you see cucumbers, avocado, celery and green apples in the mix. However, other colored produce could make its way into these smoothies as well. Fruit Smoothies: These smoothies lean heavily into fruits. You can make a smoothie with almost any fruit, whether it’s fresh, canned or frozen. Bananas and berries tend to be popular fruits in these smoothies, but any can make their way in. Protein Smoothies: These smoothies are designed to amp up the protein in your diet. The protein can either come from animals or plants, often in the form of milk, yogurt and protein powder. Because protein is required for muscle growth and repair, these smoothies are a favorite among fitness enthusiasts.

Are Convenient and Portable Scott says that well-balanced smoothies are an easy way to consume a nutritious snack if you've got a busy lifestyle. They can also be made quickly or purchased easily. Help You Eat More Fruits and Veggies According to the Centers for Disease Control and Prevention, only 1 in 10 Americans eat enough fruits and vegetables. Yet, by sipping a smoothie, you’ll probably come closer to getting the five to seven servings of fruits and veggies you need every day, says Kim Shapira, M.S., RD, a Los Angeles-based dietitian and author of This Is What You’re Really Hungry For. Numerous studies show that eating a diet high in fruits and vegetables can lower the risk of chronic diseases like heart disease and diabetes. Boost Your Digestive Health The bacteria in your gut thrive on fiber, and you can only get fiber from plants. According to a 2018 article published in the American Society for Microbiology's mSystems journal, people eating 30 or more different plant foods a week may have a more diverse gut microbiome than those eating 10 or fewer. By slurping a plant-forward smoothie, you’ll consume a good amount of fiber, aiding digestion and promoting a healthy gut, Scott says. Bonus? “Blending fruits and vegetables breaks down their cellular structure, which makes it easier for your body to absorb the nutrients,” she adds. May Help Manage Your Weight Not only can smoothies be portion-controlled, but well-balanced smoothies can help you feel fuller longer, reducing the likelihood of snacking on less nutritious options throughout the day. Plus, “the nutrient density of smoothies can help satisfy your body’s nutritional needs, potentially reducing cravings for unhealthy snacks,” Scott says.

Here's What a Dietitian Says Potential Downsides With all of the above benefits, it might surprise you to hear that there are a few strikes against smoothies. You Might Sip Too Many Added Sugars Scott says that calories can add up quickly depending on what’s in the smoothie—and many may come from added sugars. The American Heart Association recommends that people limit their added sugar intake to no more than 6 to 9 teaspoons or 25 to 36 grams per day, depending on their sex. You May Not Be Satisfied If your smoothie doesn’t have protein, fiber and healthy fat, you may feel hungry shortly after drinking it, Scott says. This can make it easier for you to overeat. “It takes about 15 minutes for a conversation to take place between your stomach and brain that you’re full,” Shapira says. Fast sipping means you might still have room to eat, increasing your odds of overeating. You Might Increase Your Risk of Health Issues Smoothie cleanses that claim to detox your body and aid in weight loss are always popping up. Yet, many of these detox programs are dangerous because they promote eating a significantly low amount of calories and can lead to deficiencies in certain nutrients, which could set you up for health issues.

Just check the added sugars, as many contain high amounts. Savor Your Smoothie: Smoothies aren’t something to be downed in one gulp but enjoyed over time. Shapira says that if you have trouble slowing down, enjoy only half the smoothie. After 15 minutes, decide if you want the second half. Vary the Ingredients: Since you can easily add many ingredients to your smoothies, use them to vary the produce you eat. To diversify your diet, add different recipes to your weekly rotation.

Shapira says. Are smoothies good for weight loss? Smoothies can help with weight loss. Just make sure you keep an eye on how big the smoothie is and what you’re putting into it, and then sip slowly, Scott says. Is it better to drink a smoothie or eat a fruit? Both can be good choices, as they each add fiber, volume and nutrient density to snacks and meals, Scott says. The choice hinges on what you prefer and what suits your lifestyle better. However, eating a whole fruit may help you feel more satisfied due to the chewing process. Is it OK to drink a smoothie every day? Absolutely, and in fact, you can optimize your daily habit by trying new ingredients that might not ordinarily be in your diet. What should a smoothie include? While smoothies can include various ingredients, Scott recommends a combination of protein, fiber and unsaturated fat. “Having all three will make sure you get a rich blend of flavors and that the smoothie is well-rounded, providing satiety and a comprehensive array of nutrients,” Scott says. The Bottom Line Whether you sip them as part of your breakfast or a snack, smoothies with the least amount of added sugars can be a convenient way to consume more nutrient-dense foods, especially if you’re falling short on fruits and veggies.
