Smoothie
View on Wikipediafrom Wikipedia
A smoothie is a beverage made by puréeing ingredients in a blender.[1] A smoothie commonly has a liquid base, such as fruit juice or milk, yogurt or ice cream. Other ingredients may be added, including fruits, vegetables, non-dairy milk, crushed ice, whey powder or nutritional supplements.
History
[edit]Health food stores on the west coast of the United States began selling smoothies with the invention of the electric blender.[2] The actual term "smoothie" was being used in recipes and trademarks by the mid-1980s.[3] In the 1960s Steve Kuhnau was inspired by his work as a soda jerk and began experimenting with smoothies. They were an alternative for the lactose intolerant Kuhnau to taste his own concoctions using unique blends of fruit juices, vegetables, protein powder, and vitamins. Kuhnau discovered early success in his smoothie sales and founded Smoothie King. Smoothie King expanded throughout the United States and would pioneer other smoothie businesses. The smoothie was then modified by fast food chains with the addition of sweeter ingredients like chocolate and Splenda.[4] In the 2000s, consumers began making smoothies at home, in part as an alternative for daily consumption of fruits and vegetables.[5]
Nutrition

The nutrition of a smoothie depends on its ingredients and their proportions. Many smoothies include large or multiple servings of fruits and vegetables, which are recommended in a healthy diet and intended to be a meal replacement.[6] However, fruit juice containing high amounts of sugar can increase caloric intake and promote weight gain.[7][8] Ingredients such as protein powders, sweeteners, or ice cream may be used.[6][9][10] One study found smoothies to be less satiating, despite providing the same amount of energy as unblended foods.[11]
Types
[edit]Green smoothie
[edit]A green smoothie typically consists of 40–50% green vegetables (roughly half), usually raw green leafy vegetables, such as spinach, kale, Swiss chard, collard greens, celery, parsley, or broccoli, with the remaining ingredients being mostly or entirely fruit.[12][13][14] Most green leafy vegetables have a bitter flavor when served raw, but this can be ameliorated by choosing certain less-bitter vegetables (e.g. baby spinach) or combining with fruits or other sweet ingredients.[15]
Protein smoothie
[edit]A protein smoothie is a combination of water or milk, protein powder, fruits, and vegetables. They can be consumed any part of the day and are used as protein supplement for those who want to increase their protein intake. Protein powder can have a chalky taste when mixed individually by itself with milk or water. The protein smoothie improves the taste of the protein powder through addition of fruits or other sweeteners.[16]
Yogurt smoothie
[edit]A yogurt smoothie is a smoothie that includes yogurt as a protein source and to add a creamy texture to the drink. Greek yogurt, specifically, is included as a thickener (due to its strained consistency) and in order to take advantage of its claimed health benefits.[17]
Around the world

India has lassi, a yogurt smoothie composed of crushed ice, yogurt, sugar or salt, and in some cases fruits, like mango.[18]
Fruit sharbat (a popular West and South Asian drink) sometimes include yogurt and honey. Pineapple smoothies made with just crushed ice and sugar are common in Southern India. Lassi or a very similar drink exists by different names in other countries. For example, doogh in Iran, shumlay in Afghanistan and some parts of Pakistan, ayran in Turkiye, and dhallë in Armenia.

A smoothie is a thick, cold beverage made by blending fruits, vegetables, and a liquid base such as water, milk, yogurt, or fruit juice, often incorporating additional ingredients like nuts, seeds, oats, or ice for texture and flavor.[1][2]
Originating in the 1930s following the commercialization of electric blenders like the Waring model in 1939, smoothies initially appeared as fruit-based drinks in consumer recipe booklets and gained traction in the 1960s through health food stores on the West Coast of the United States, where they were promoted as nutritious alternatives to sodas.[3] By the 1970s, innovations like lactose-free versions expanded their appeal, and today they are a staple in global diets, with commercial preparations recognized by the USDA for contributing to meal components such as fruits, vegetables, dairy, and proteins in child nutrition programs.[4]
Nutritionally, smoothies retain the fiber from whole fruits and vegetables—unlike juicing—supporting digestive health, satiety, and daily intake goals of at least 2 cups of fruit and 2.5 cups of vegetables per the USDA MyPlate guidelines, while delivering vitamins like C for immunity and K for bone health.[1][2] Common ingredients include bananas, berries, spinach, and almond butter for creaminess, though calorie content can range from 120 to over 800 or more per serving in high-calorie variants depending on additions like nuts, dairy, oats, sweeteners, or protein powders, potentially leading to higher blood sugar or weight gain if overconsumed.[2][5] Their versatility allows customization for dietary needs, from vegan options to high-protein blends, making them a convenient way to boost antioxidant intake and reduce chronic disease risk.[1][2]
Definition and Basics
Definition
A smoothie is a thick, cold beverage made by puréeing raw fruits, vegetables, or other ingredients with a liquid base such as water, milk, fruit juice, yogurt, or ice in a blender.[6] This process creates a smooth, homogeneous mixture that combines the nutritional elements of the whole ingredients without separating solids from liquids.[7] Unlike juices, which involve extracting liquid from fruits or vegetables through straining or pressing and thereby removing much of the pulp and fiber, smoothies retain the full fiber content of the ingredients, contributing to a thicker texture and potential digestive benefits.[8] In contrast to milkshakes, which are typically dairy-based desserts blended with ice cream, milk, and sweeteners for a creamy, indulgent consistency, smoothies prioritize fresh, whole produce and lighter bases to emphasize health-oriented refreshment rather than sweetness.[9] Smoothies generally have a smooth, pourable consistency that can vary from drinkable to spoonable, depending on the ratio of solids to liquids, and are often served chilled in glasses or bowls to enhance their refreshing quality.[10] Optional toppings such as nuts, seeds, or granola may be added, particularly for thicker varieties presented as bowls, to provide added texture and nutrition.[11]Key Ingredients
Smoothies rely on a variety of key ingredients to achieve their characteristic blend of flavor, texture, and nutrition, with each component serving a specific function in the final product. Liquid bases form the foundation, providing the hydration needed for blending while influencing consistency and taste; common options include water for a light, neutral profile; dairy or plant-based milks such as almond, oat, or soy for added creaminess and subtle nuttiness; and fruit juices like orange or apple for natural sweetness and tang. Yogurt and kefir also function as versatile bases, contributing thickness, a tangy flavor, and probiotic elements that enhance the smoothie's digestibility.[12] Fruits and vegetables constitute the core of most smoothies, delivering vibrant flavors, natural sweetness or earthiness, and a wealth of vitamins, minerals, and fiber while helping to balance texture through their varying water content and pulp. Popular fruits include bananas, which provide creaminess and mild sweetness due to their starch content; berries such as strawberries, blueberries, and raspberries for tart, antioxidant-rich bursts; and tropical options like mangoes or pineapple for juicy, exotic sweetness. Vegetables like spinach and kale add subtle green notes and nutrient density without overpowering flavor, while avocado lends a velvety texture from its healthy fats. Seasonal and exotic choices, including acai berries or dragon fruit, introduce unique tartness or mild sweetness and higher levels of specialized antioxidants.[12][13][14] Add-ins further customize smoothies by enhancing nutritional profiles, adjusting sweetness, or modifying mouthfeel, often without significantly altering the base flavors. Sweeteners such as honey or dates offer natural caramel-like depth and balanced energy; protein sources like nut butters (e.g., almond or peanut) or seeds including chia and flaxseeds provide satiety, creaminess, and omega-3 fatty acids. Thickeners like ice cubes or frozen yogurt contribute a chilled, frosty texture ideal for refreshing drinks, while superfoods such as matcha powder for earthy umami or spirulina for its algal protein boost deliver concentrated nutrients like antioxidants and vitamins.[12][13][14] When sourcing ingredients, preference is given to fresh or frozen produce to maximize nutrient retention, as frozen fruits and vegetables—harvested at peak ripeness and quickly preserved—maintain comparable levels of vitamins, minerals, and antioxidants to their fresh counterparts, often exceeding those in produce shipped long distances. Organic options are favored for their higher concentrations of phenolic compounds and lower residues of nitrates or pesticides, helping to avoid unwanted additives in processed items and supporting cleaner flavor profiles.[15][16][17]History
Ancient Origins
The ancient origins of smoothie-like beverages trace back to diverse pre-modern cultures where fruits, seeds, and other natural ingredients were manually processed into thick, nourishing drinks using simple grinding tools, serving purposes from daily hydration to ritual sustenance. In Mesoamerica, the Olmec civilization pioneered the preparation of cacao-based beverages as early as 1500 BCE by fermenting, roasting, and grinding cacao beans into a paste mixed with water to create frothy drinks and gruels. The Maya and later the Aztecs refined these practices, blending the cacao paste with water, spices, and occasionally floral essences on stone metates (grinding slabs) and manos (handstones) to produce energizing, foam-topped elixirs consumed during ceremonies and as elite nourishment.[18] In ancient India, during the Vedic period (circa 1500–500 BCE), yogurt-based beverages akin to modern lassi emerged, involving the blending or churning of fermented milk (dahi) with water and additions like fruits, herbs, or spices to yield cooling, probiotic-rich drinks valued for aiding digestion and balancing bodily humors in Ayurvedic traditions.[19] Mediterranean societies, including the ancient Greeks and Romans from around 800 BCE onward, created fruit purees by mashing figs and other produce with honey; Romans in particular boiled figs to produce "fig honey" (a concentrated syrup) and pounded dried figs with nuts and seasonings for versatile flavorings that were diluted into beverages for sweetening and refreshment.[20] Sub-Saharan African communities developed early fermented drinks by mashing local fruits with grains like sorghum or millet, a practice rooted in indigenous traditions spanning millennia, resulting in thick, effervescent beverages that provided portable nutrition amid diverse climates and as part of communal rituals.[21] Central to these traditions were pre-blender implements such as mortars, pestles, and stone grinders, employed across cultures since at least 35,000 BCE to pulverize ingredients into smooth pastes or slurries, enabling the creation of stable, travel-friendly concoctions that preserved nutrients and flavors without advanced machinery.[22] These foundational methods across continents emphasized blending for enhanced digestibility and portability, setting the stage for the evolution of nutrient-dense beverages into their 20th-century forms.Modern Development
The invention of the electric blender marked a pivotal advancement in the development of modern smoothies, enabling efficient home puréeing of fruits and other ingredients. In 1910, Hamilton Beach introduced the Cyclone Drink Mixer, an early electric appliance designed for blending beverages like milkshakes, which laid the groundwork for creating smooth, homogeneous mixtures on a wider scale.[23] By the 1930s, the availability of such blenders coincided with the emergence of health food stores on California's West Coast, where vendors began selling fruit-ice blends inspired by Brazilian recipes, adapting fresh fruits with ice for nutritious, chilled drinks targeted at health-conscious consumers.[24] Following World War II, smoothies gained momentum during the 1960s counterculture era, as the health food movement promoted them as wholesome alternatives to processed beverages, emphasizing natural ingredients and vitality. This period saw smoothies transition from niche offerings in health stores to symbols of wellness amid the rise of macrobiotic diets and organic living. In 1973, Steve Kuhnau opened the first Smoothie King location in Kenner, Louisiana, blending fruits with vitamins and proteins to create allergy-friendly options, which helped standardize and popularize the drink as a purposeful health aid.[25][26] Commercialization accelerated in the 1980s and 2000s, driven by fitness trends that integrated smoothies into gym culture as recovery drinks. The launch of Jamba Juice in 1990 in San Luis Obispo, California—initially as Juice Club—exemplified this shift, offering fresh fruit blends in a casual retail setting that appealed to active lifestyles. During this time, supplement additions like protein powders became common, enhancing smoothies' appeal for muscle building and post-workout nutrition amid the aerobics and bodybuilding booms.[27][28] In the 2020s, heightened health awareness has steered smoothie innovation toward plant-based formulations and reduced-sugar profiles, reflecting broader dietary shifts toward sustainability and metabolic health. These variants often incorporate alternative milks and natural sweeteners to cater to vegan and low-glycemic preferences, further embedding smoothies in everyday wellness routines.[28]Preparation
Methods and Equipment
High-speed blenders are the primary equipment for home smoothie preparation, as their powerful motors, often exceeding 1000 watts, effectively pulverize fruits, vegetables, and ice to create a smooth, creamy texture without chunks.[29] Models like the Vitamix 5200 excel in this role due to their variable speed settings and durable blades, which handle tough ingredients efficiently for consistent results.[29] Compact options such as the NutriBullet Pro 900 provide similar high-speed blending for single servings, with refined nutrient-extraction blades that process fibrous produce in under a minute.[30] Food processors serve as an alternative for larger batches, chopping and pureeing bulk ingredients before transferring to a blender for final mixing, which is particularly useful when preparing multiple servings at once.[31] For optional pulp removal after blending, fine-mesh strainers or cheesecloths can be employed to filter out fibrous remnants, yielding a silkier consistency if desired.[32] In commercial settings, such as smoothie shops or juice bars, industrial blenders with reinforced construction and higher capacities—up to 2.4 L (80 ounces) or more—are standard to withstand continuous use and large volumes.[33] Brands like Vitamix and Blendtec offer models with noise suppression and self-cleaning cycles, ensuring reliability during peak hours.[34] Juicers, particularly centrifugal or masticating types, are commonly used to extract liquid bases from fruits and vegetables, providing a clear foundation that blends seamlessly with other components.[32] Automated dispensers facilitate quick serving in high-traffic environments, maintaining hygiene by portioning pre-blended mixtures without direct handling.[34] The basic workflow for smoothie preparation begins with layering ingredients in the blender to optimize blending and prevent clogging: start with liquids at the bottom to facilitate blade movement, followed by dry additions like powders, then leafy greens and soft fruits, and end with harder items or ice on top.[35] This sequence ensures even distribution and reduces strain on the motor, as the liquids create a vortex that draws solids downward.[36] Blending typically requires 30-60 seconds on high speed to achieve optimal aeration and a uniform texture, incorporating air for a lighter mouthfeel while fully emulsifying the mixture.[37] For storage and safety, pre-freezing components like fruits and greens in portioned freezer bags or silicone containers preserves freshness and simplifies assembly, allowing blends to be made directly from frozen states without dilution.[38] This method minimizes oxidation and nutrient loss during prep.[39] Hygiene practices are crucial, especially for dairy-based smoothies; always use clean equipment, wash hands thoroughly before handling ingredients, and store finished blends in airtight containers in the refrigerator at 40°F (4°C) or below to inhibit bacterial growth.[40] Consume within 24-48 hours or freeze immediately if longer storage is needed, avoiding room-temperature exposure to prevent spoilage in perishable mixes.[41]Common Techniques
One common technique in smoothie preparation involves layering ingredients in the blender to ensure even blending and optimal texture. Start with liquids at the bottom, such as water, milk, or plant-based alternatives, to create a base that allows the blades to move freely. Follow with powders or dry mixes like protein powder or spices, then add softer fresh fruits and vegetables, and finally incorporate frozen items last to avoid straining the motor and achieve a smooth consistency.[42] This order helps maintain a consistent vortex during blending, preventing clumps and reducing the need for excessive processing time.[43] Ratio guidelines play a key role in achieving the desired thickness; use 2 to 3 parts produce with ½ to 1½ parts liquid, depending on desired consistency, for a pourable yet substantial texture. Adjust liquid upward for thinner results or downward for thicker ones to accommodate varying ingredient densities, such as denser frozen fruits requiring more liquid.[1] These proportions ensure the smoothie blends efficiently without becoming watery or overly thick, promoting better nutrient incorporation.[12] To adjust texture, incorporate ice or frozen fruit for added chill and creaminess, as the frozen elements naturally thicken the mixture while eliminating the need for extra sweeteners. For dairy-free options, add oats or avocado to enhance body without compromising smoothness; a quarter avocado or a handful of rolled oats can provide natural creaminess and satiety.[42] These adjustments allow customization based on preference, with frozen components contributing to a frosty mouthfeel ideal for warm days.[44] Flavor balancing is achieved by combining complementary elements: sweet components like bananas provide natural sugars, tart berries such as strawberries or raspberries add brightness, and creamy bases like yogurt introduce richness to harmonize the profile. Mid-blend tasting and tweaking—pausing to sample and adding small amounts of citrus for acidity or honey for sweetness—ensures a well-rounded taste without overpowering any single note.[44] This iterative approach prevents imbalances, resulting in a cohesive flavor that encourages regular consumption.[42] Advanced tips include pre-portioning ingredients into freezer bags for quick assembly; measure fruits, vegetables, and add-ins into zip-top bags, seal, and freeze for up to three months to streamline morning routines while preserving freshness. Additionally, incorporate heat-sensitive ingredients like fresh greens or vitamin-rich add-ins last in the blending process to minimize exposure to friction-generated heat, thereby helping to retain nutrients such as vitamin C.[45] These strategies enhance efficiency and nutritional integrity, making smoothie preparation accessible for daily use.[46]Types of Smoothies
Fruit-Based Smoothies
Fruit-based smoothies primarily feature fruits as the core ingredients, leveraging their inherent flavors and nutritional profiles to create naturally sweet beverages without relying heavily on added sugars. Common combinations emphasize tropical fruits such as mango and pineapple, which provide a tangy, exotic taste, or berry mixes like strawberry and banana, offering a creamy yet vibrant texture. These blends capitalize on the fruits' natural fructose content, which delivers sweetness while minimizing the need for sweeteners, making them a straightforward option for everyday consumption.[47][48] Among popular examples, berry blends incorporating blueberries and raspberries stand out for their high antioxidant content, including compounds like anthocyanins that support cellular health. Citrus fusions, such as those with orange and kiwi, deliver a significant vitamin C boost, enhancing immune function through the fruit's ascorbic acid. These combinations are favored for their balanced flavor profiles, where the tartness of berries or citrus complements milder fruits like banana, resulting in a refreshing drink that appeals to a wide audience.[49][50][51] In preparation, incorporating frozen fruits is a key technique to achieve a sorbet-like texture, as the ice crystals from frozen pieces create thickness without diluting the flavor, unlike adding ice cubes. Seasonal variations, such as summer peach smoothies, highlight the use of fresh, ripe produce to enhance taste and incorporate local availability, blending peaches with yogurt or milk for a velvety consistency. This method preserves the fruits' nutrients during blending and allows for quick assembly in a standard blender. For hot weather, particularly refreshing and hydrating fruit-based smoothies emphasize water-rich fruits like watermelon and tart berries, which provide natural cooling effects and electrolytes. A ultra-simple example is the easiest watermelon smoothie: blend 5 cups cubed watermelon until smooth, offering maximal hydration due to watermelon's high water content. Another popular option is the Summer in a Cup smoothie: blend 1¼ cups frozen raspberries, 1 frozen banana, ½ cup pomegranate juice, ¾ cup orange juice, and ¾ cup unsweetened almond milk until creamy, delivering a tart berry blast. These recipes are 100% vegan, rely on whole foods, and are ideal for beating the heat with natural electrolytes and cooling properties.[52][53][54] The appeal of fruit-based smoothies lies in their refreshing, dessert-like quality, evoking a guilt-free indulgence through bright flavors and smooth mouthfeel. They are commonly enjoyed as breakfast options for a nutrient-packed start to the day or as post-workout refreshments to aid recovery with easily digestible carbohydrates and hydration. This versatility contributes to their popularity in promoting fruit intake in a convenient form.[55][56][57]Vegetable and Green Smoothies
Vegetable and green smoothies feature a primary base of nutrient-dense vegetables, particularly leafy greens like spinach, kale, arugula, or celery, blended with liquids such as water or plant-based milks to create a thick, drinkable consistency.[2] These smoothies often incorporate fruits like apples or bananas to balance the earthy flavors, resulting in profiles that emphasize wellness over sweetness; for instance, a kale-apple blend provides a vibrant green hue and subtle tartness, while cucumber-mint variations promote hydration through high water content in the vegetables.[2] A simple breakfast example includes 1 banana, a handful of spinach or kale, 1 apple or berries, 200 ml yogurt or milk, and optional nut butter; all ingredients are blended for 1 minute until smooth. This vitamin-rich preparation is ideal for rushed mornings.[58] An example of a light, hydrating vegan green smoothie ideal for hot weather is the Refreshing Green Smoothie. This recipe is 100% vegan, uses whole foods, and offers natural electrolytes and cooling effects through its water-rich ingredients. It is prepared by blending 1 frozen mango, 1 green apple, 6 romaine leaves or spinach, 2 celery stalks, ½ cucumber, ½ lemon, and 2 cups cold water or coconut water until smooth.[59] Unlike fruit-dominant options, the vegetable focus retains the full fiber from whole produce, enhancing satiety and nutritional density.[60] The composition of these smoothies offers notable benefits, including elevated fiber levels from the vegetable bases, which support digestive health by promoting regular bowel movements and potentially reducing the risk of chronic conditions like heart disease.[2] A typical 8-ounce serving with spinach, kale, apple, and banana delivers about 5 grams of fiber, aligning with dietary recommendations of 25-38 grams daily for adults.[2] Additionally, chlorophyll-rich greens contribute antioxidants that may aid in reducing inflammation and supporting detoxification processes, with studies indicating potential anti-cancer effects from increased intake of such compounds in vegetable-heavy diets.[61] One challenge in preparing vegetable and green smoothies is the inherent bitterness of greens like kale, which can deter beginners from consistent consumption.[2] This is commonly addressed by adding acidic elements such as lemon or pineapple to neutralize flavors, or by gradually increasing green portions in recipes to build palatability over time.[2] For variations, detox-oriented blends often feature root vegetables like beets and carrots for their liver-supporting compounds, as seen in recipes combining these with ginger and apple.[62] Non-traditional savory twists, such as tomato-basil smoothies incorporating celery and lime, offer an umami alternative, blending tomatoes for lycopene benefits alongside fresh herbs.[63]Specialty Smoothies
Specialty smoothies incorporate targeted additives to cater to particular dietary or performance-oriented goals, distinguishing them from standard fruit or vegetable blends. Protein smoothies, for instance, commonly feature whey protein powder, pea protein isolate, or Greek yogurt blended with bases like milk or plant-based alternatives, along with fruits such as bananas and nut butters for flavor and texture. A representative formulation includes 1 cup of vanilla yogurt, 1 cup of 2% milk, a medium banana, 2 tablespoons of wheat germ, and 2 tablespoons of protein powder, blended until smooth to create a high-calorie, nutrient-dense option suitable for post-exercise recovery.[64] For those avoiding dairy, a lactose-free variant substitutes soy yogurt and vanilla soy milk while retaining the banana, wheat germ, and protein powder.[65] These additions elevate the protein content, often reaching 30-40 grams per serving, making them a convenient vehicle for muscle support needs.[66] High-calorie specialty smoothies, designed for weight gain or high-energy needs, utilize whole foods like nuts, fruits, dairy, and oats to achieve 800+ calories per serving. These are blended until smooth, with ice added for thickness if desired, and sweetness adjusted using honey or dates. Examples include:- Peanut Butter Banana Boost (~900-1000 calories): 2 ripe bananas, 4 tbsp natural peanut butter, 2 cups whole milk, ½ cup rolled oats, 2 tbsp honey (optional).
- Avocado Berry Dream (~800-900 calories): 1 whole avocado, 1½ cups mixed berries (frozen or fresh), 1 cup full-fat Greek yogurt, 1 cup whole milk or coconut milk, 2 tbsp maple syrup or honey, handful spinach (optional for nutrients).
- Chocolate Peanut Butter Indulgence (~950-1100 calories): 2 bananas, 4 tbsp peanut butter, 2 tbsp unsweetened cocoa powder, 2 cups whole milk, ½ cup oats, 1-2 tbsp honey or a scoop of chocolate protein powder (optional).
- Banana Oat Nut Power (~850-1000 calories): 2 bananas, ½ cup rolled oats, 3 tbsp almond or peanut butter, handful mixed nuts (almonds, walnuts), 2 cups whole milk, 1 tsp cinnamon.
To increase calories further, add 1-2 tbsp olive oil or coconut oil (~120-240 cal), use heavy cream instead of milk, or incorporate dates or dried fruit; consume 1-2 per day alongside meals, with estimates approximate based on standard nutrition data—track precisely using an app.[67][68]
Nutrition and Health
Nutritional Profile
Smoothies typically provide a balanced macronutrient profile that varies based on ingredients, with a standard 16-ounce (approximately 473 ml) serving often ranging from 200 to 500 calories, depending on the inclusion of fruits, vegetables, dairy or plant-based liquids, and add-ins like nuts or protein powders; however, certain high-calorie formulations, such as those incorporating high-fat add-ins like nut butters, whole milk, oats, and nuts, can reach 800-1100 calories per serving. For example, a Peanut Butter Banana Boost with 2 ripe bananas, 4 tbsp natural peanut butter, 2 cups whole milk, ½ cup rolled oats, and 2 tbsp honey (optional) yields approximately 900-1000 calories, while an Avocado Berry Dream with 1 whole avocado, 1½ cups mixed berries, 1 cup full-fat Greek yogurt, 1 cup whole milk or coconut milk, 2 tbsp maple syrup or honey, and optional spinach provides about 800-900 calories. Carbohydrates generally dominate, contributing 40 to 60 grams primarily from natural sugars in fruits, while dietary fiber content hovers between 5 and 10 grams when using whole fruits and vegetables, aiding digestion and satiety. Protein levels can reach 5 to 15 grams if yogurt, nut butters, or seeds are incorporated, and fats remain low at 2 to 10 grams unless enriched with avocados or oils.[42][2][5] Micronutrient density is a key strength of smoothies, particularly from fresh produce; for instance, vitamin C content can provide 20 to 100% of the daily value per serving from citrus or berries, while vitamins A and K are abundant in greens like spinach, offering 10 to 50% daily value. Potassium levels are notably high, often exceeding 500 mg from bananas or leafy vegetables, supporting electrolyte balance. Berries contribute antioxidants such as flavanols, which promote cardiovascular health, though a 2023 study found that adding bananas to berry smoothies reduces flavanol bioavailability by up to 84% due to the fruit's polyphenol oxidase enzyme, which degrades these compounds during blending.[42][76] Nutritional variability arises from base choices and preparation; dairy-based smoothies, such as those with yogurt, deliver higher calcium (200-300 mg per serving) and complete proteins compared to plant-based alternatives like almond or oat milk, which may add 1-3 grams of fiber but often require fortification for comparable micronutrients. Using whole fruits and vegetables in smoothies preserves fiber integrity, unlike juicing, which removes pulp and reduces fiber by up to 90%. For example, a typical 16-ounce fruit smoothie (e.g., banana, berries, and yogurt) might contain 350 calories, 50 grams of carbohydrates, 6 grams of fiber, 10 grams of protein, and 80 mg of vitamin C, whereas a green variant (e.g., spinach, apple, and almond milk) could offer 250 calories, 40 grams of carbohydrates, 8 grams of fiber, 5 grams of protein, and higher vitamin K (150 mcg).[77][78][79]| Nutrient | 16-oz Fruit Smoothie (Example) | 16-oz Green Smoothie (Example) |
