A 300 mL (10.1 oz) serving of a standard fruit smoothie provides 168 calories.

One cup (240 mL or 8.1 oz) of a standard fruit smoothie contains 134 calories.

One 473 mL (16 oz) Jamba Juice Strawberries Wild contains 250 calories. A 591 mL (20 oz) Smoothie King Angel Food smoothie delivers 330 calories. One 450 mL (15.2 oz) bottle of Naked Juice Mighty Mango contains 290 calories. A 450 mL (15.2 oz) bottle of Bolthouse Farms Strawberry Banana provides 250 calories. One 450 mL (15.2 oz) bottle of Evolution Fresh Super Fruit Greens contains 140 calories.

Smoothies provide some health benefits like providing a concentrated source of dietary fiber and supplying potent antioxidants due to its use of whole blended fruits and vegetables. This beverage, frequently called a "fruit blend," "liquid fruit," "blended puree," or "nutrient slush," remains a popular way to increase plant-based intake. A list of the health benefits of smoothies are shown below.

• Promotes Digestive Regularity: Blending whole fruits retains the natural pectin and cellulose required for intestinal motility. A study by Slavin and Lloyd (2012), "Health Benefits of Fruits and Vegetables," found that the fiber in whole plant foods supports a healthy diet by improving gut microbiome diversity.
• Enhances Cellular Defense: The presence of anthocyanins and flavonoids in berry-based blends neutralizes free radicals. Research by Liu (2003), "Health-promoting effects of common fruits," demonstrated that the synergistic effect of phytochemicals in fruit significantly reduces oxidative stress markers.
• Supports Immune Function: A 100 g (3.5 oz) serving of a mango-based blend provides 30 mg of Vitamin C, fulfilling 33% of the Daily Value (DV). This nutrient density is essential for white blood cell production and skin integrity.
• Assists in Electrolyte Balance: The high potassium content in banana-based smoothies, delivering 358 mg per 100 g (3.5 oz), helps regulate blood pressure.
• Provides Convenient Nutrient Fortification: Smoothies serve as a standard vehicle for health-boosting additives like chia seeds or spirulina, which increase the intake of omega-3 fatty acids and iron.

Smoothies has been known to cause some unwanted effects like rapid insulin spikes and unintended weight gain due to its high liquid fructose content and reduced satiety signals. This drink, often referred to by the nicknames "liquid candy," "sugar bomb," or "fructose slurry," presents several metabolic challenges. A list of the downsides of smoothies are shown below.

• Triggers Elevated Glycemic Response: The mechanical blending process breaks down cellular structures, leading to faster sugar absorption than whole fruit. A study by Flood-Obbagy and Rolls (2009), "The effect of fruit in different forms on energy intake and satiety," found that consuming fruit in liquid form results in a significantly higher blood glucose peak compared to eating solid fruit.
• Promotes Overconsumption of Calories: Liquid energy does not trigger the same fullness hormones as solid food. Research by Malik et al. (2010), "Sugar-Sweetened Beverages and Risk of Metabolic Syndrome and Type 2 Diabetes," indicates that regular intake of high-sugar beverages is a primary driver of obesity and metabolic syndrome.
• Contributes to Dental Enamel Erosion: The acidic nature of citrus and berry bases lowers the pH of the mouth. A study by Jain et al. (2007), "The erosive potential of some beverages available in the UK," notes that fruit smoothies possess a high erosive potential that can lead to permanent tooth enamel thinning.
• Provides Excessive Refined Sugar: Commercial varieties, such as the 710 mL (24 oz) Bahama Mama from Tropical Smoothie Cafe, contain 106 g of sugar, which exceeds the recommended daily limit for three standard adults.
• Reduces Natural Chewing Stimuli: Consuming pre-digested liquid meals bypasses the cephalic phase of digestion, which can lead to poorer nutrient absorption and decreased satiety.
• Risk of Nutrient Imbalance: Excessive consumption of green smoothies containing raw oxalates from spinach can interfere with calcium absorption and increase the risk of kidney stones in susceptible individuals.

No, most commercial smoothies are not good for you because they contain 60 g to 106 g of sugar per standard serving, which interferes with a balanced metabolic state. Healthy individuals should consume no more than 237 mL (8 oz) of a home-made, vegetable-heavy smoothie per day to avoid excessive fructose intake. The major benefits include the intake of 5% of the DV for fiber and 33% of the DV for Vitamin C per small serving, but these are often negated by the high caloric density. It is an ideal addition to a diet only when prepared without fruit juices, honey, or sorbet bases.

The calories in smoothies change based on the inclusion of fat-dense nuts, protein powders, and the ratio of vegetables to high-sugar fruits. A standard fruit smoothie contains 56 calories per 100 g (3.5 oz), but replacing fruit with leafy greens reduces the count to 45 calories per 100 g (3.5 oz). The addition of 15 g (1 tbsp) of peanut butter increases the energy density to 110 calories per 100 g (3.5 oz) because fat provides 9 calories per gram. Protein-heavy versions reach 85 calories per 100 g (3.5 oz) as protein provides 4 calories per gram while increasing the total solids in the liquid. Commercial smoothies using sorbet or sherbet bases, like those at Jamba Juice, reach 310 calories per 473 mL (16 oz) compared to 180 calories in a vegetable-led Detox Island Green from Tropical Smoothie Cafe.

Smoothies often have more sugar and calories than standard milk tea, providing 250 to 510 calories per large serving. A standard 473 mL (16 oz) fruit smoothie contains 310 calories, while a 473 mL (16 oz) regular milk tea generally contains 250 calories when served without toppings. Smoothies utilize whole fruit purees and often sorbet, which adds a significant carbohydrate load, whereas milk tea relies on a brewed tea base mixed with smaller amounts of milk or non-dairy creamer. The calorie difference depends heavily on the milk variety and the volume of liquid sweeteners used in each beverage. Adding 150 calories of tapioca pearls to milk tea can equalize the energy content with a medium-sized fruit smoothie.

The origin of the smoothie is traced back to the 1920s in the United States, coinciding with the invention of the electric blender by Stephen Poplawski and later refinement by Fred Waring. Initially, these blended fruit drinks were sold in health food stores as "fruit shakes" to customers seeking dairy-free alternatives to traditional milkshakes. The term "smoothie" was first utilized in the 1930s by West Coast health food manufacturers who were inspired by traditional Latin American fruit purees known as "batidos."

In the 1960s and 1970s, the beverage gained significant cultural momentum during the health food movement, primarily led by Stephen Kuhnau, who founded Smoothie King in 1973 after experimenting with blended fruit to manage his own food allergies. By the 1990s, the smoothie transitioned from a niche health product to a mainstream global commodity with the launch of Jamba Juice, which standardized the use of frozen yogurt and sherbet bases. Today, the beverage has evolved into a multi-billion dollar industry, with modern iterations focusing on "clean labels," functional additives like protein and spirulina, and the popularization of thick smoothie bowls derived from Brazilian acai traditions.
