Juicer VS Blender Health Benefits

What Is The Difference Between Juicing and Blending

The difference between juicing and blending is what’s left out of the process. With juicing, you’re essentially removing all fibrous materials, leaving only the liquid of the fruits and vegetables. With blending, you get it all — the pulp and fiber that bulks up the produce.


A. Pros of Blending

Both juicing and blending take food and pulverize it. Juicers separate the juice from the pulp, so the pulp can be discarded. But blenders make use of everything. And that can be a good thing because the main component of the pulp that juicers discard is fiber.

Blended fruits and vegetables retain all their fiber, a key nutrient for healthy digestion and chronic disease prevention. Fiber is precious, especially considering that fewer than 5% of all Americans consume the recommended daily amounts of fiber.

The pulp that juicers waste and blenders preserve also provides an abundance of flavonoids, which are a potent class of phytonutrients.

With blended fruits and veggies, there are only so many you can drink before you start to feel full. The pulp, skin, and fiber help increase the volume of the drink, which fills you up and limits your total calorie consumption.

Naringin, an Important Flavonoid

One study compared the phytonutrient content of blended vs juiced grapefruit and found that blended grapefruit, with both juice and pulp, contained seven times the amount of naringin, a potent flavonoid that fights cancer and inflammation, and may be effective in treating type 2 diabetes and other metabolic diseases.

If you’re watching your weight, (for more information on weight loss, please check out our blog post here), smoothies are more filling than juices, thanks to all those fibrous parts of the fruits and vegetables that trigger those “that’s enough, thank you” signals from the stretch receptors in your stomach.

One way to make smoothies more satiating is to add some form of healthy fat, like avocado, seeds, or nuts.

The fat will slow down the absorption of the sugars (for more information on sugar, please check out our blog post here), in the fresh fruit, so you can stay full longer, and not suffer from a sugar spike and subsequent crash.

How To Clean Blenders

And maybe it shouldn’t matter as much as it does, but blenders are definitely easier to clean than juicers. They don’t have lots of parts to disassemble, scrub, dry, and reassemble.

And if you’ve ever watched a Vitamix demo at Costco, you know about the trick where you fill the dirty blender container with soapy water, snap on the lid (don’t forget the lid, unless you like soap suds on your ceiling!), and run the blender for 15 seconds to remove all food particles and stains.

B. Cons of Blending

While they aren’t prone to spiking your blood sugar nearly as much as juices, sweet smoothies can still raise blood glucose levels and contribute to metabolic syndrome.

Since smoothies are liquid meals, we can consume them too quickly, and therefore take in excess calories before we’re aware of being full.

Additionally, humans evolved to chew our food well and slowly. The fruits, roots, and leaves our ancestors ate were far more fibrous than the gentle peaches, plums, and apples that we’re all used to.

Smoothies reduce the need for chewing even further, which can mean weaker masseter muscles and underdeveloped oral cavities, especially in babies and small children.

Nitric Oxide, a Wonderful Nutrient

Nitric oxide, the vasodilator chemical that you get from leafy greens, gets metabolized by enzymes and bacteria in your saliva. Skip the chewing, and you reduce your intake of this wonderful nutrient.

Advantage of Making Your Own Smoothies

If you make your own smoothies, you can maintain complete control over the quality of ingredients they’re made of. But that’s not true if you drink commercially blended smoothies from restaurants, airport kiosks, or supermarket beverage cases.

Those products, designed to appeal to consumer taste buds, may contain unwanted ingredients like refined sugar, high fructose corn syrup, (for more information on sugar, please check out our blog post here), and natural and artificial flavor or colorings. And they rarely if ever use organically grown fruits or vegetables.

4 Blender Types & Recommendations

Are you up for blending? If so, you’ll need — drum roll, please — a blender. There are several different styles that will fit different needs and budgets.

1. Stick Blenders

The least expensive, smallest, and least powerful is the immersion or “stick” blender. These blenders are best for sauces and dips, and for pureeing hot ingredients like soups, that you don’t want to blend in a container while boiling hot.

If you will be using it for hot items, make sure the parts that contact the food are metal and not plastic to avoid leaching toxins into your meals. One well-reviewed model is the KitchenAid 2-Speed Hand Blender.

2. Single-Serving Blenders

Slightly bigger and more powerful, there’s the single-serving or personal blender. This style typically comes with a container that you can drink from since the blade is housed in the base.

These also come with lids, so you can take your smoothie on the go, as well as other accessories like whisks and extra chopping blades for onions and other veggies. The Hamilton Beach Personal Blender is an inexpensive model with strongly positive reviews.

3. Kitchen Blenders

Next in the pecking (or blending) order is the regular old kitchen or full-size blender — the one you probably picture when you think “blender.” These babies sit on the countertop and can handle most blending tasks.

One of my favorite things about them is the creative labels for the various settings: blend, grind, pulverize, liquify, and crush. As longtime household staples, they vary widely in power, materials, and quality of the build.

Make sure you get one whose motor can handle whatever you plan to throw at it. If your smoothies will involve ice or frozen fruit, look for a higher wattage on the motor, and check online reviews for durability.

Also, I highly recommend choosing a model with glass, not plastic, containers. The Oster Reverse Crush checks all the boxes and even has the ability to send its 6-point blade in reverse to clear up jams and optimize your blending experience

4. Specialty Blenders

Finally, the sovereign of the blender world is the specialty or combo blender. These workhorses can easily blend frozen stuff. One brand even advertised its prowess by destroying iPhones, iPads, and camcorders in its whirring blades. (As fun as that sounds, I don’t recommend it.)

One top-of-the-line specialty blender is the ever-popular Vitamix. The latest models feature smart technology, wider and shorter containers (so they finally fit under kitchen counters), and quieter motors.

While you might get sticker shock if you’re used to blenders in the $30-$100 dollar range, Vitamix blenders are probably the best overall value when you factor in the lifetime cost of ownership.

A more recent entrant to the high-end, specialty blender market is Ninja, whose models feature cool “blade towers” and presets for smoothies, frozen drinks (umbrellas optional), and even mixing dough.

Pros & Cons of Juicers & Juice

Juicing is a process that extracts water and nutrients from produce while discarding most of the fiber. As with blending, there are pros and cons to this process.

A. Pros of Juicing

Juicing concentrates the nutrients, as the vast majority of the vitamins and minerals in fruit are typically in the juice — not the pulp and fibrous material. As a result, juicing can increase the quantity and bioavailability of antioxidants like vitamin C for better absorption.

Also, it’s easier for people with impaired digestion to assimilate nutrients in juices than in whole fruit or blended smoothies.

Because fiber binds to the sugars in fruits and vegetables and slows down their digestion, juicing can provide a quicker dose of energy. While most of us don’t need a sugar rush, athletes who will be metabolizing lots of calories in a short time can benefit from drinking juice right before an event.

Benefits of Beet Juice

Beet and cherry juices, in particular, have been investigated as performance enhancers in athletes.

Beet juice appears to aid the long-distance runner. In one study, elite runners in their 20s were instructed to run to exhaustion on a treadmill, given a red juice supplement for 15 days, and then asked to repeat the treadmill test.

Those given beet juice achieved “substantial improvements in the time to exhaustion” compared to those drinking the placebo. Aside from the compelling results, I want to know how you create placebo beet juice with no beets in it!
(for more information on beets, please check out our blog post here).

Not to be outdone by beets, tart cherries also improved endurance in athletes, sometimes when given as little as an hour and a half before an event. I hope the World Anti-Doping Agency keeps beets and cherries off its banned substances list!

B. Cons of Juicing

Juicing isn’t all moonlight and roses, however. As we saw, juicing removes most of the fiber, which means rapid absorption of sugar into the bloodstream.

As a result, you may experience sugar spikes, which can tax the insulin system, followed by sugar crashes, which can include symptoms as varied as fatigue, irritability, lightheadedness, dizziness, and anxiety, among many others.

Juice also may not be as satiating as solid food or blended food, which can lead you to consume more than you would otherwise and still not feel satisfied.

Sugar Content

That can be a problem, especially with juices that are high in sugars, as they can pack a lot of calories into a small (and rapidly consumed) volume.

Consider apple juice: you can drink a cup in a few seconds. While it would take you a lot longer to consume the equivalent number of medium-sized apples (three, as it turns out). And you’d probably get full somewhere on your second apple.

While a cup of juice won’t even tickle your “full-o-meter.”

The Difference Between Commercial Juices and Fresh, Raw Juice

Also, there’s a big difference between commercial juices and fresh, raw juice. Commercial juices, like commercial smoothies, may contain unhealthy ingredients. Commercial fruit juice, in particular, turns into little more than junk food when it’s pasteurized and filtered.

Vegetable juice (with the arguable exception of carrot juice, which is actually still pretty sweet, with nine grams of sugar per cup) doesn’t suffer the same fate and can be a potent way to absorb nutrients swiftly.

Juicing also wastes a lot of valuable nutrition. The pulp that gets thrown away when you clean your juicer includes fiber and other nutrients that bind to it.

Sugar Content on Juices and Sodas

Some commercial fresh juices contain as much, or even more, sugar than sodas. Research published in 2014 found that on average, fruit juices contain 45.5 grams of fructose per liter, not far off from the average of 50 grams per liter in sodas.

Minute Maid apple juice was found to contain 66 grams of fructose per liter, higher than both Coca-Cola and Dr. Pepper! Although smoothies may have less, sugar should be a concern regardless.

And finally, juicers are often messy and take a fair amount of time and effort to clean thoroughly, which may mean they get used less in the long run.

4 Juicer Types & Recommendations

Just as with blenders, there are various kinds of juicers. The three types competing for your dollars and counter space are auger/low-speed, centrifugal, and masticating juicers.

1. Auger Juicers

The auger/low-speed models spin, as you might have guessed from the description, juice slowly. This keeps the heat low, which means your juice will be truly raw. They have a pretty small footprint on your counter and eject their pulp to the side.

Many models include a tap, so you can keep the juice in the juicer until you’re ready to drink. Omega makes a version of this type of juicer that gets excellent reviews.

2. Centrifugal Juicers

More common, and less expensive, are the centrifugal juicers, which essentially extract juice with a combination of grating and rotating really fast. The pulp goes down, while the lighter liquid gets spun out like a kid on a Gravitron carnival ride.

Because of the quick processing time, these are the least efficient at getting the maximum nutrition from your produce. A quality model is the Omega J4000 High-Speed Pulp Ejection Juicer.

3. Masticating Juicers

Next, there are the masticating juicers, which feature a horizontal auger that crushes and grinds the produce under great pressure, extracting perhaps the maximum nutrition of any of the types.

The Champion Classic 2000 Juicer is pricey, but tends to last, and includes a 5-year overall warranty.

4. Manual Juicers

Finally, you can also find manual juicers specifically for citrus fruits. One example is the Gourmia Citrus Juicer, which uses leverage to add force to your natural strength. The company claims that its juicer can handle pomegranates as well as oranges, lemons, and grapefruits.

4 Benefits of Blending vs Juicing

Believe it or not, there are actually some documented health benefits to both blending and juicing.

1. Disease Fighting Benefits

For one thing, both blenders and juicers increase the bioavailability of phytochemicals from many raw plant foods by reducing the size of the food particles and increasing their surface area.

One study of Korean kernel fruit (apples, pears, persimmons, and mandarins) found that blending increased their antioxidant properties while juicing increased vitamin C bioavailability.

Of course, the best way to reduce the size of the food that makes it into your stomach is to eat slowly and chew thoroughly. But for many of us, that’s a challenging (and time-consuming) habit to adopt.

However, the more phytochemicals we eat, the lower our disease risk, especially for conditions like heart disease, type 2 diabetes, cancer, and neurodegenerative diseases like Alzheimer’s and Parkinson’s.

Raw VS Cooked Vegetables and Fruits

Because blending and juicing typically use raw produce, they can provide significantly more phytochemicals that usually degrade when cooked. For example, isothiocyanates are phytochemicals found in cruciferous veggies that have powerful anticancer effects.

We absorb more isothiocyanates from raw than cooked veggies, so we can get a max dose by blending or juicing our cabbage, cauliflower, watercress, and turnips rather than cooking them.

2. Heart Health Benefits

There’s good evidence that drinking fruit and vegetable juices can also specifically protect against heart disease, primarily through lowering blood pressure and improving the blood lipid profile (basically, lowering LDL cholesterol and triglycerides).

3. Gut Health Benefits

Juicing may also benefit the gut microbiome. In 2017, a team at the UCLA medical school took 20 healthy adult volunteers and gave them nothing but vegetable and fruit juice for three days, after which they followed their regular diets for two weeks.

At the end of the study, there was a significant increase in the populations of “good” gut bacteria, including the ones associated with weight loss, (for more information on weight loss, please check out our blog post here), increased vasodilation (opening of blood vessels) through nitric oxide production, and reduced free radical production from blood lipids.

A triple win, from just three days of juicing!

4. Anti-Inflammatory Benefits

There’s some evidence that plant-rich smoothies may help reduce inflammation associated with autoimmune diseases. One pilot study that’s currently underway is including a morning smoothie as part of a protocol to decrease pain and joint swelling in people with rheumatoid arthritis.

The Summary

Juicing has a variety of benefits, including the greater concentration of nutrients per ounce, increased consumption of fruits and vegetables, and enhanced absorption of nutrients. It may also help people who have difficulty eating their vegetables to stomach the taste.

Juicing and Fiber

On the other hand, with juicing you’re missing out on important fiber. You could also be missing out on other important compounds present in the pulp and membranes of the produce.

With blending, you’re getting everything the fruit and vegetables have to offer, but the pulpy texture may be unappetizing to some.

With Yogurt or Not

Some experts believe you could minimize the rise in blood sugar from liquid calories by adding sources of fiber, protein, or fat, such as avocado, chia seeds, protein powders, or unsweetened Greek yogurt. But others disagree.

“We do not recommend any liquid calories,” says dietitian Kimberly Gomer, MS, RD, LDN. “For weight loss, always eat the fruits and veggies — don’t drink them. If weight loss isn’t an issue, then the smoothie would win the prize over the juicing.

In both cases, there is a caveat to all of the benefits: sugar. Because of sugar, Gomer urges caution, particularly if weight loss is your goal.
