But... Are Smoothies Good for You?

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.

This article explains everything you need to know about smoothies, including their potential health benefits and downsides, whether they aid weight loss, and tips for making nutritionally balanced versions at home.

What are smoothies?

Smoothies are beverages made by blending together fruit, dairy or non-dairy milk, and sometimes additional ingredients such as yogurt, honey, or ice. The result is a creamy and satisfying drink that is packed with nutrients and vitamins. They are typically enjoyed as a healthy snack or meal replacement and come in a variety of flavor combinations.

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.

Because smoothies are so customizable, it’s fairly easy to pack them with nutrients.

What about the potential health benefits of smothies

Smoothies are a great way to pack a variety of nutrients into a single glass. Here are some of the health benefits of drinking smoothies:

Boosts nutrient intake: Smoothies allow you to easily incorporate a variety of fruits, vegetables, and other healthy ingredients into your diet, increasing your overall nutrient intake.
Supports weight loss: Many smoothie recipes are low in calories and high in fiber, making them a filling and nutritious snack option.
Improves digestion: Blending fruits and vegetables into a smoothie can help to break down the fibers and make them easier to digest.
Increases hydration: Many smoothies contain water-rich fruits like cucumbers and watermelons, making them an excellent way to stay hydrated.
Promotes heart health: Smoothies made with ingredients high in antioxidants and healthy fats, such as berries, avocado, and nuts, can help to improve heart health.
Boosts energy: Smoothies can be a great source of natural energy thanks to the vitamins, minerals, and other nutrients they contain.
Supports immune system: Fruits and vegetables high in vitamins C and E, such as oranges, spinach, and strawberries, can help to boost the immune system when incorporated into smoothies.

It's important to note that while smoothies can be a nutritious and delicious part of a healthy diet, they should not be relied upon as the sole source of nutrition. A balanced diet that includes a variety of whole foods is always best.

Smothies in numbers

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.

The World Health Organization (WHO) recommends that adults eat at least 5 servings (around 400 grams) of fruits and vegetables per day. However, most people fall short of this mark.

If you find you’re not eating enough fruits or veggies, a smoothie can be a delicious way to pack in 2–3 more servings.

Smoothies 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

Yet, many people are not meeting their daily fiber needs — especially those who follow Western diets.

The U.S. Department of Agriculture (USDA) recommends a daily intake of at least 38 grams of fiber for men and 25 grams for women. Research indicates that most Americans, on average, eat only 16 grams of fiber each day.

With the right ingredients, smoothies can be an excellent way to boost your fiber intake.

Some of the most fiber-rich foods are also common smoothie ingredients, including fruits, vegetables, whole grains (such as soaked oats), nuts, seeds, and legumes (such as white beans).

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.

The American Heart Association recommends limiting your intake of added sugar to no more than 9 teaspoons (37.5 grams) per day for men and 6 teaspoons (25 grams) per day for women.

Commercially prepared smoothies tend to be higher in added sugar than homemade versions, but it ultimately depends on the ingredients used in each recipe.

For instance, Smoothie King’s 20-ounce (590-mL) The Hulk Vanilla Smoothie packs 47 grams of added sugar, which is well above your daily sugar recommendation.

Their Original High Protein Pineapple Smoothie is a much better option, as it provides only 4 grams of added sugar in the same serving size.

Many sugary ingredients are easy to identify, such as granulated sugar, honey, maple syrup, ice cream, sherbet, and agave nectar.

Nonetheless, you should keep in mind that nut butters, protein powder, flavored yogurt, fruit-flavored sauces, and sugar-sweetened juices and nondairy milks are all potential sources of added sugar.

Occasionally indulging in small quantities of added sugar is not likely harmful, but if you drink smoothies frequently, it may be best to limit sugary ingredients as much as possible.

When making smoothies at home, use whole fruits, such as a ripe banana, to add sweetness instead of honey or maple syrup.

When buying premade smoothies, try to limit or avoid added sugar, mainly focusing on smoothies that include whole foods like fruits and veggies.

For bottled smoothies, you can find the added sugar content on the label. For made-to-order ones, check the company website or ask for nutrient information at the counter.

Do smoothies aid weight loss?

Yes, smoothies can aid weight loss when consumed as part of a balanced diet. Many smoothie recipes are low in calories and high in fiber, making them a filling and nutritious snack option.

However, it's important to note that the effectiveness of smoothies for weight loss depends on the ingredients used. Some smoothies can be high in added sugars or fat, which can counteract the weight loss benefits. To maximize the weight loss benefits of smoothies, it's best to use low-fat dairy or non-dairy milk, use fruits and vegetables high in fiber, and limit added sugars.

Additionally, drinking a smoothie should not replace a meal but rather be used as a supplement to a healthy diet that includes a variety of whole foods.

Smoothies can be tailored to meet your needs

You can drink smoothies as a snack or meal replacement, but it’s a good idea to know which types to choose — especially if you have a specific fitness or body composition goal in mind.

There’s a common misconception that smoothies are inherently low calorie snacks, but some smoothies pack over 1,000 calories depending on their size and ingredients.

Generally, a 200–300-calorie smoothie with 10 grams of protein is a great snack, whereas a 400–800-calorie smoothie providing at least 20 grams of protein is better suited as a meal replacement. It’s best to assess your goals and calorie needs to determine your specific needs.

The difference between the two may be as simple as adjusting the serving size.

Many smoothie chains provide the ingredient and nutrition information for each of their products, which usually come in 16–32-ounce (475–945-mL) servings.

When making smoothies at home, be sure to control your portion size. Fats like nuts, seeds, nut butters, full fat yogurts, and avocado will provide more calories but increase nutrient density. Meanwhile, sugary add-ins like syrups will provide more calories without quality nutrients.
