Smoothies are an increasingly popular wellness trend and frequently marketed as a health food.
These versatile beverages are portable, family-friendly, and modifiable for any taste or dietary preference. Smoothies are easy to prepare yourself, but you can also purchase fresh or bottled ones from specialty cafés and most major grocery stores.
While some types are loaded with veggies and fruit, others pack sugar or other unhealthy ingredients. As such, you may wonder whether they’re a healthy choice.
What are smoothies?
Smoothies are thick, creamy beverages usually blended from puréed fruits, vegetables, juices, yogurt, nuts, seeds, and/or dairy or nondairy milk.
The most basic smoothie starts with two essential ingredients — a base and a liquid. From there, you can combine ingredients to your liking.
Many smoothies include frozen produce or ice cubes to give the final product the cool, icy consistency of a milkshake. However, their flavor profiles vary tremendously depending on the ingredients.
Common ingredients
Popular ingredients in homemade and store-bought smoothies include:
Fruits: berries, banana, apple, peach, mango, and pineapple
Vegetables: kale, spinach, arugula, wheatgrass, microgreens, avocado, cucumber, beetroot, cauliflower, and carrots
Nuts and seeds: almond butter, peanut butter, walnut butter, sunflower seed butter, chia seeds, hemp seeds, and flax meal
Herbs and spices: ginger, turmeric, cinnamon, cocoa powder, cacao nibs, parsley, and basil
Nutritional and herbal supplements: spirulina, bee pollen, matcha powder, protein powder, and powdered vitamin or mineral supplements
Liquid: water, fruit juice, vegetable juice, milk, nondairy milk, coconut water, iced tea, and cold brew coffee
Sweeteners: maple syrup, raw sugar, honey, pitted dates, simple syrup, fruit juice concentrates, stevia, ice cream, and sorbet
Others: cottage cheese, vanilla extract, soaked oats, cooked white beans, silken tofu, and dairy or nondairy yogurt
Types
Most smoothies can be classified into one or two of the following categories — though there’s significant overlap between them:
Fruit smoothies. As the name implies, this kind of smoothie usually features one or more types of fruit blended with fruit juice, water, milk, or ice cream.
Green smoothies. Green smoothies pack leafy green vegetables and fruit blended with water, juice, or milk. They tend to be heavier in veggies than regular smoothies, though they often include a little fruit for sweetness.
Protein smoothies. Protein smoothies usually start with one fruit or vegetable and a liquid, as well as a major protein source like Greek yogurt, cottage cheese, silken tofu, or protein powder.
Potential health benefits
Many people consume smoothies as a morning meal or afternoon snack. They can be a great way to incorporate more healthy foods into your diet.
May help boost fruit and vegetable intake
Smoothies made primarily from fresh or frozen produce may increase your consumption of fruits and vegetables, which provide a diverse array of essential vitamins, minerals, fiber, and antioxidants.
Together, these nutrients may reduce inflammation, improve digestion, and lower your risk of chronic conditions like heart disease, osteoporosis, obesity, and age-related mental decline.
May support increased fiber consumption
Fiber is an important nutrient that aids digestion by preventing constipation and supporting the growth of beneficial bacteria in your digestive tract.
Early research suggests that a healthy, thriving community of gut bacteria can help reduce inflammation, promote healthy immune function, and support mental health.
Adequate fiber intake is also linked to a reduced risk of chronic illnesses, such as heart disease and type 2 diabetes.
Some varieties contain large quantities of added sugar
The difference between a healthy and unhealthy smoothie largely depends on the quality and quantity of its ingredients.
Smoothies’ biggest pitfall is their propensity to contain large quantities of added sugar.
Added sugar reduces the nutrient density of smoothies. Furthermore, routinely consuming too much added sugar may increase your risk of chronic ailments like heart disease, diabetes, and liver disease.
Commercially prepared smoothies tend to be higher in added sugar than homemade versions, but it ultimately depends on the ingredients used in each recipe.
Summary
Smoothies are popular meals and snacks and can suit almost any taste or dietary preference. Their healthiness is largely determined by their ingredients.
The most nutritious smoothies are made with whole foods like fruits, vegetables, yogurt, and healthy fats, while those with lots of added sugars aren’t as nutrient-dense and may contribute to negative health effects over time.
Smoothies high in protein and fiber may even aid weight loss by keeping you full.
If you’re looking for a creative way to boost your fruit and veggie intake, smoothies may be the way to go.
