The first day of summer brings a perfectly refreshing celebration: National Smoothie Day on June 21. As the sun reaches its peak, Americans turn to ice-cold, blended beverages packed with fruit (and sometimes veggies) to quench their thirst and nourish their bodies. Smoothies – whether bright green kale blends or tropical strawberry-banana swirls – have become a staple of modern healthy eating and on-the-go snacking.
National Smoothie Day, fittingly observed on the summer solstice, invites everyone to break out the blenders and raise a toast to these frosty concoctions. It’s a day to celebrate creativity in a cup, the delightful fusion of flavor and nutrition. And like other drink-inspired holidays (say, National Matcha Day for tea lovers), this one is all about blending fun with wellness, U.S.-style.
How to Celebrate National Smoothie Day
Celebrating National Smoothie Day is as easy as sip, smile, repeat. Start your day with a homemade smoothie for breakfast – it’s a great way to pack in some fruit (and vegetables, if you’re adventurous) before you even leave the house. A classic recipe could include a banana, a handful of berries, a scoop of yogurt, a splash of milk or juice, and a couple of ice cubes. Blend until frothy, and you have a delicious morning boost.
You might also use this day to try something new with your smoothies. Perhaps experiment with bold ingredients you haven’t tried before. Ever add avocado to a smoothie? It lends a creamy texture without a strong taste. How about a green smoothie with spinach or kale? With the right mix of pineapple or apple to add sweetness, you might be surprised how enjoyable a “green drink” can be. National Smoothie Day is a chance to break out of your routine – maybe toss in some flax or chia seeds for extra fiber, or a spoonful of almond butter for richness and protein.
If you’re out and about, consider visiting a local smoothie bar or juice shop on June 21. Many chains have been known to run promotions: for example, in past years some gave loyalty members a free smoothie with purchase. You could turn it into an outing with friends – a “smoothie crawl” sampling different spots in town. And for a festive summer touch, why not make it a smoothie pool party or picnic? Blend up big batches of smoothies and serve them in mason jars or fun glasses. Garnish with fruit slices or tiny umbrellas to give it that vacation vibe. However you do it, take a moment to appreciate the vibrant colors and flavors of your smoothie, and toast to the first day of summer.
Smoothie Recipes and Recommendations
One of the best parts of smoothies is how customizable they are. Here are a few crowd-pleasing smoothie ideas to inspire your National Smoothie Day menu:
- Berry Blast Smoothie: Blend together strawberries, blueberries, and raspberries with a banana, a scoop of Greek yogurt, and a splash of orange juice. The result is a tangy-sweet, antioxidant-packed treat. For an extra chill, use frozen berries.
- Green Goddess: Combine baby spinach or kale with pineapple chunks, mango, and coconut water. The sweetness of the fruit masks the greens, yielding a bright green smoothie that’s as nutritious as it is refreshing.
- Peanut Butter Banana Protein: Mix a ripe banana, a tablespoon of peanut butter, a cup of milk (dairy or almond), and a scoop of chocolate or vanilla protein powder. This smoothie is creamy and indulgent – almost like a milkshake – but provides a good dose of protein for a post-workout refuel.
- Tropical Sunrise: Blend mango, pineapple, and peaches with a squeeze of lime and some carrot juice. The carrot juice adds vitamins and a vibrant color, while the tropical fruits make you feel like you’re on an island getaway.
If you’re looking for products to elevate your smoothie game, consider investing in a quality blender. A high-powered blender (such as a Vitamix or Ninja) can pulverize ice and fibrous veggies with ease, resulting in that ultra-smooth texture. But you don’t need a pricey machine – even an immersion blender can work in a pinch for single servings. Other useful gadgets include reusable smoothie straws (often wider for thick drinks) and portable blender bottles for taking your creations on the go.
On the ingredient front, keeping some frozen fruit on hand is a smart move. Frozen berries, mango, or acai packets can eliminate the need for ice and give your smoothie a creamy, cold consistency. Don’t forget staples like yogurt, milk (or dairy alternatives), and juice. Many smoothie aficionados also stock mix-ins like protein powders, matcha (green tea powder) for a caffeine kick, or spirulina for a superfood boost. One timely tip: June is also when farmers’ markets overflow with fresh berries and stone fruits – an ideal time to buy produce in season (often cheaper and more flavorful) to use in your smoothies. You can even freeze any surplus for later. With the right ingredients and tools, you’ll be ready to whip up delightful smoothies long after National Smoothie Day has passed.
History of Smoothies
The concept of the smoothie has roots that stretch back to the early 20th century, though people around the world have been pureeing fruits into drinks for much longer (think of traditional beverages like India’s mango lassi). The actual term “smoothie” began appearing in recipes and advertisements by the mid-1930s, around the time electric blenders became widely available. In California, health food pioneers were quick to adopt the new gadget: by the 1930s and 40s, West Coast health stores and juice bars were blending up fruit drinks to entice health-conscious customers. These early smoothies were often based on orange juice or other fruit juices, mixed with ice and sometimes dairy or egg for body.
The real smoothie boom, however, came in the late 20th century. In 1973, a young health enthusiast named Steve Kuhnau founded Smoothie King in Louisiana, one of the first chains devoted entirely to blended fruit drinks. Around the same time, the fitness and natural foods movement was on the rise in the U.S., and smoothies – especially those packed with yogurt, protein powder, wheat germ, or other add-ins – became a popular item at health food shops. By the 1990s and 2000s, smoothies had hit the mainstream. National chains like Jamba Juice (founded in 1990 in California) helped turn smoothies into a cultural phenomenon, offering dozens of fruity flavors and boosting the idea of a drinkable meal or snack. Today, from mall food courts to supermarket bottled beverage aisles, smoothies are everywhere.
As for National Smoothie Day itself, its origin is a bit unclear – it’s an unofficial holiday likely popularized in the 2010s by smoothie brands and aficionados on social media. Tropical Smoothie Café, Jamba, and other companies often use June 21 as a marketing moment, offering special deals or even free smoothies to celebrate the occasion. Regardless of who “invented” the holiday, June 21 is the perfect date: the start of summer, when Americans are more than ready to blend up something cool, sweet, and possibly healthy. The day highlights how far the smoothie has come from niche health tonic to beloved summer treat.

Fun Facts about Smoothies
Born from the blender: The smoothie revolution owes a lot to the invention of the electric blender in the early 20th century. Stephen Poplawski is credited with creating the first drink mixer blender in 1922. Before that, making a puree drink was labor-intensive. Once blenders hit the market, recipes for “smoothed” fruit beverages (the word “smoothie” wasn’t common yet) started appearing in cookbooks and magazines, especially by the 1930s when health fads took off.
Chain reaction: Smoothie King, founded in 1973, claims to be the world’s first smoothie franchise. Not far behind, Jamba Juice (originally called Juice Club) opened its doors in 1990 in California. These and other chains helped popularize smoothies across the U.S., turning what was once an obscure health store item into a mainstream snack. Today, Jamba has over 800 locations, and Smoothie King over 1,000 worldwide – proof that smoothies have gone big time.
Social media sensation: Smoothies are an Instagram favorite – the vivid colors and artful garnishes (think chia seeds arranged on top or perfectly placed fruit) make for eye-catching posts. The hashtag #smoothiebowl became trendy in recent years, referring to a thicker smoothie poured into a bowl and topped with ingredients like granola, coconut flakes, and fresh fruit slices. Essentially, it’s a smoothie that you eat with a spoon, often arranged in beautiful patterns. These bowls are not only delicious but also a canvas for food artistry.
Big gulp records: In 2015, students at McGill University in Montreal set a world record by blending the world’s largest smoothie – a mind-boggling 3,121-liter (824-gallon) strawberry smoothie. The giant drink was prepared as part of a charity event and served to hundreds of people. Meanwhile, another record was set in 2019 for the most varieties of smoothies on display: one restaurant showed off 266 different smoothie flavors at once! It’s safe to say there’s a smoothie out there for every taste.
Health halo – earned or not: Smoothies often wear a “health halo,” and for the most part they are a nutritious choice – a great way to consume fruits, fiber, and hydration. However, not all smoothies are created equal. Some store-bought or chain smoothies can be loaded with sugar (a “pure fruit” smoothie can easily contain 50+ grams of natural sugar). That’s why many nutritionists suggest balancing fruits with some protein (yogurt, nut butter) and maybe a veggie to slow down sugar absorption. Still, on National Smoothie Day, most folks aren’t worrying – it’s hard to feel guilty about slurping down a bunch of blended berries!
