Picture this: it was a hot, summery day and you just got back from your morning run. There sitting on your kitchen bench is a glass of fresh, vibrant juice straight out from the juicer. Sipping on it, every gulp delivers a rush of nutrients straight to your cells, quenching not just your thirst but all signs of weariness.
Sounds enticing? That’s the appeal of juicing.
From just a “trend” that peaked in the mid-2000s to now a staple essential in the lives of many health-conscious individuals worldwide, juicing, dare we say, is not a fad – it is here to stay.
The thing is, what does juicing really entail? What’s about it that garners such a huge following? Perhaps more important is the question: what is juicing?
What is Juicing?
Putting it simply, juicing is the process of extracting juices from plant tissues such as fruits or vegetables. It is a modern term for a long-standing practice that stretches centuries back, a time where fruits and herbs were mashed for quick access to their nutrients for medicinal purposes.
Over the years, the concept of juicing evolves continuously and with the introduction of centrifugal juicers in the 1970s, juicing finally takes a shape more recognizable to us today. One can say this is the turning point where juicing becomes more accessible to the everyday consumer, but it is not until recent years that juicing transitions from a niche health trend to a mainstream practice.
All thanks to the nutritional benefits and convenience that comes with it. You see, juicing extracts all the nutrient-rich liquids from fruits and vegetables so that people can consume everything in one, single serve. Compared to having to eat different fruits and vegetables as a whole (which some struggle to), juicing offers that practical and tasty solution in one nutrition-concentrated glass that is convenient and easily digestible.
And that, is where the appeal of juicing lies.
It doesn’t stop there though. Another reason why juicing resonates with so many people is that it brings fun to the table too. The seemingly endless variety of combinations one gets to be creative with is a key attraction that lures (and retains) people into the world of juicing.
Not to mention, it allows people to consume a diverse range of fruits and vegetables that may otherwise be absent from their diet, thereby enhancing their nutritional intake breadth.
The Science Behind Juicing
So, how does this whole juicing thing work?
On the surface, it seems rather straightforward: choose your fruits and vegetables, extract their liquid and ta-da, you get your juice! The thing is, what’s with all these nutrient extraction that we’ve been talking about, and how does it differ from consuming fruits and vegetables as a whole?
The key aspect lies in how it affects nutrient absorption. With fruits and vegetables, all their essential vitamins, minerals and antioxidants are trapped or locked within the cell walls of the plant’s fibrous content. When we consume them as a whole, our digestion system will have to work hard to break down these cell walls to access said nutrients.
With juicing, all these ‘pre-digestion’ is already done for you pre-consumption. The juicing process breaks down the plant cells to liberate the nutrients so that when you drink your glass of juice, your body can absorb all the goodness directly and more efficiently.
Juicing also increases the density of nutrients per volume consumed. Think about this: how many carrots can you eat in one go? 1? Maximum 2? Now how many carrots can you juice at once? Definitely more than that right? This ability to concentrate nutrients in one glass is what makes juicing so alluring.
Now that we know of the nutritional mechanics of juicing, how do you go about extracting all these natural goodness? For that, and also a topic that we cannot go past when it comes to the world of juicing, is “the juicer”.
Types of Juicers
Technological advancements have led to a variety of juicers being invented with one surpassing the other but all centered around one goal – to simplify the process and maximize the benefits of juicing.
There are basically three types of juicers if we are to categorize them: Centrifugal, Masticating and Triturating. Each is different in the way they extract thereby impacting the quality of the juice, the ease of use, and the clean-up process.
Centrifugal juicers are the most affordable option out of the three. Always readily available, this is a great choice for juicing beginners. It shreds fruits and vegetables with a high-speed spinning blade before separating the juices from the pulp using centrifugal force. While centrifugal juicers are definitely fast and user-friendly, they can generate quite the noise (due to their high speed) and with speed, heat is generated which can potentially degrade some of the nutrients.
Masticating juicers are also known as slow or cold-press juicers which took the world by storm in the mid 2000s, masticating juicers operate at lower speeds and use an auger to crush the produce against a stainless-steel mesh screen to extract juice.
This method results in a high juice yield and less heat generation, thereby preserving more nutrients. Generally more expensive than their centrifugal counterparts but masticating juicers remain a constant favourite among health enthusiasts due to the quality of juice they produce.
Triturating juicers are the top-tier on the market, also known as twin-gear juicers. True to that, these juicers operate by way of using two gears that rotate inwards to crush and grind fruits and vegetables into a very fine pulp. This process yields the highest quantity of juice and the driest pulp, indicating an excellent extraction efficiency.
Like masticating juicers, they operate slowly and generate very little heat so nutrients are preserved effectively. As one would expect with an outstanding performance like that, they are the most expensive out of all three and may also be more complex to assemble and clean.
Understanding these types of juicers is essential in choosing the right juicer for your needs. As we continue to explore the ins and outs of juicing, you’ll slowly learn the knowledge necessary to make an informed decision about the type of juicer that fits you perfectly.
Generally speaking though, budget, how often you plan to juice, the variety of produce you want to juice and your nutritional goals are amongst the most common factors that influence a person’s decision.
A Beginner’s Guide to Juicing
Juicing is not complicated. As a beginner, here’s what you can do:
1. Choose the Right Juicer: As we’ve discussed, there are various types of juicers available. Make your choice based on your budget, your juicing goals, and the time you can dedicate to juicing and cleaning the juicer.
2. Selecting Your Produce: The next step is to decide what fruits and vegetables you want to juice. As a beginner, it’s advisable to start with sweet fruits like apples or pears, which produce lots of juice and give a pleasant taste. For vegetables, cucumbers and celery are excellent choices due to their high water content. As you become more comfortable with juicing, you can start to experiment with a wider variety of produce.
3. Preparation: Before juicing, wash all produce thoroughly to remove any pesticides or dirt. Harder vegetables like carrots or beets should be peeled, while apples and pears can be juiced with their skin on. Make sure to remove any hard pits or seeds.
4. Start Juicing: Now, you’re ready to start juicing! Turn on your juicer, add your fruits and vegetables, and let the machine do its work. Remember, it’s best to drink the juice immediately after making it to get the most nutritional benefits.
5. Experiment: The world of juicing is all about experimentation. Don’t be afraid to try different combinations of fruits and vegetables. For instance, a simple beginner’s recipe could be 2 apples, 1 cucumber, and a handful of spinach. This will give you a sweet yet slightly earthy juice, packed with a wide range of nutrients.
6. Clean Up: After juicing, clean your juicer immediately. This will prevent pulp and juice residue from drying and becoming difficult to remove. Most juicers come with a brush to help clean the mesh screen and other parts.
Benefits of Juicing
Juicing is not just about consuming fruits and vegetables in an easy-to-drink format only – there is a whole lot more than that.
Here are some of the key benefits associated with juicing:
Increased Fruit and Vegetable Intake
We’ve talked about this briefly above but juicing really does increase a person’s daily fruit and vegetable intake. Not just in amount, but variety as well. This is because people often combine a number of fruits and vegetables when they juice as opposed to using just one particular type (the latter does have its following though).
In any case, we made our point with our carrot example above and it continues to stand here. One type or multiple, there’s no denying that juicing increases one’s consumption of these nutrient-rich foods, a daily intake recommendation that many struggle to meet otherwise.
Potential Weight Loss
Juicing is also often associated with weight loss plans. When incorporated into a balanced diet, it does prove to be an excellent supplement especially vegetable-based juices as they are typically low in calories yet high in nutrients.
However, it is important to note that juices should only work as a support and not total replacement of whole foods entirely. This is because there are other nutrients and fibre that the body needs to derive from whole foods to maintain balance and health.
Many people use juicing as a form of detoxification. While our body is naturally equipped with organs like the liver and kidney to do that, some believe that juicing, with its high concentration of nutrients, aid in this process. As with weight loss, this shouldn’t be taken to the extreme and it’s always important to consult a healthcare provider before starting any detox regimen.
Enhanced Nutrient Absorption
As we discussed earlier, juicing helps break down the cell walls of fruits and vegetables thereby enhancing the bioavailability of nutrients. This means that your body can absorb and utilize these nutrients more efficiently, leading to potential health benefits.
The benefits of juicing are manifold and they extend beyond the ones we’ve discussed here. As you embark on your juicing journey, you might discover unique benefits that cater to your individual health needs and goals. Remember, moderation and balance are key.
Having said that, juicing does have its fair share of controversies.
The Arguments (and Common Misconceptions) Surrounding Juicing
The most common debate has to be the lack of fibre. Remember we said above that all the nutrients of fruits and vegetables are trapped in the plant’s fibrous content? To extract them, the juicing process has to break down and remove much of these fibres, leaving behind a fibrous pulp.
With dietary fibres playing critical roles in the human’s health such as promoting healthy digestion, regulating blood sugar levels, and supporting a feeling of fullness, this aspect of juicing does cast doubts with regards to its benefits.
Let’s put it this way. Juicing is never meant to be a substitution or replacement of whole food or meal intakes. A juicing diet where one is to cut off food entirely is never recommended (and shall never be the way).
Just because you’ve started drinking juice doesn’t mean you can just stop eating whole fruits and vegetables. On the same note, just because juicing removes the fibre element doesn’t mean you should avoid juicing altogether. Consider it as a supplement to a balanced diet instead.
Other common misconceptions include:
1. Juicing is a Quick Fix for Weight Loss: While juicing can support weight loss as part of a balanced diet, it is not a magic solution. Weight loss involves a combination of a balanced diet, regular exercise and a healthy lifestyle. Juicing can provide valuable nutrients with few calories but it should not replace balanced, whole food meals.
2. Juicing Detoxes Your Body: As we mentioned earlier, our bodies are naturally equipped to detoxify through organs like the liver and kidneys. While a nutrient-rich juice can support these functions, it does not ‘detox’ your body in the way many juicing cleanses suggest. A well-rounded diet, hydration, and regular exercise are the best ways to support your body’s detoxification process.
3. All Juices are Created Equal: The nutritional value of your juice depends largely on what you put into it. A juice packed with leafy greens and low-sugar fruits is going to be much healthier than a juice overloaded with high-sugar fruits. Always aim for a good balance of fruits and vegetables in your juices.
Precautions and Potential Side Effects of Juicing
And while we are on the topic, let’s look at some of the potential downsides of juicing so that you can take precaution:
High Sugar Intake
This, you’ve probably heard most when people talk about juicing. Yes, some fruits do contain a high level of sugar and when consumed in large quantities, they can raise your blood sugar levels considerably (despite them being natural sugar). This is why you should incorporate more vegetables in your juices, and take note of your consumption level especially for people with diabetes or those watching their sugar intake.
Lack of Fibre
As discussed but the lack of fibre in juices can also lead to less satiety and potential spikes in blood sugar. Balancing it off with fibre-rich whole fruits, vegetables and grains to help offset this.
Potential Allergic Reactions
If you’re allergic to a particular fruit or vegetable in its whole form, you’ll likely be allergic to it in juice form as well. Always test new fruits and vegetables cautiously.
Too much of anything can turn even the most beneficial to something bad. For some, the high levels of certain nutrients in juices, particularly if consumed in large quantities, can lead to digestive discomfort such as bloating, indigestion or diarrhea.
Certain populations need to be extra careful when considering a juicing regimen. For example, individuals with kidney disorders need to watch their potassium intake so juices like orange and tomato may need to be avoided as they can exacerbate their condition. Similarly, individuals with diabetes or blood sugar concerns should be mindful of the sugar content in their juices.
It is important that you understand the “misconceptions” and potential side effects of juicing so that you’re better equipped to make informed decisions. This way, you can get the most out of your juicing journey.
There is no denying that juicing has surged in popularity in recent years and that is largely propelled by a growing health consciousness that more and more people have developed nowadays – the desire to maintain a healthy body through the consumption of nutrient-rich foods.
Juicing is a versatile practice that can enhance this. We’ve pretty much traversed the landscape of juicing in this whole post, from its origin to the scientific explanation behind it, from its numerous benefits to the common misconceptions and potential side effects – we’ve touched on all that.
Whether you’re looking to boost your nutrient intake or simply add some variety to your diet, juicing can be a refreshing and nutritious addition to a balanced lifestyle when done correctly. However, as with anything in life, there are both good and bad sides. Moderation is always the key, remember that. Do your research first and consult a healthcare provider when in doubt.
