Slow juicer juicing

There’s no refuting the fact that fruits and vegetables are good for us. After all, research has shown that a diet high in fruits and vegetables can keep plenty of diseases such as cancer and heart disease at bay. So, isn’t it great that drinking juices can make such a daunting task easy?


You may have noticed the wide range of juicers that are available now. To make things simpler, the juicers that are in the market now can be split into two types, centrifugal juicers and slow juicers.


Centrifugal juicers


Centrifugal juicers are the most common type of juicers. Typically, such juicers work by having a fast spinning metal blade spin against a mesh filter, which separates the juice from flesh. However, it is said that due to the metal blade’s rapid spinning, heat is generated, which oxidises nutrients and destroy the enzymes of the fruits and vegetables.


Slow juicers


On the other hand, slow juicers which are also known as cold press juicers or masticating juicers, are said to produce more nutritious juices. By squeezing fruits and vegetables at a slow but high pressure, less heat (thereby the name cold press) and higher juice yield is obtained.


What the research says


A study done in 2013, showed the influence of extraction methods on the quality and functional aspects of broccoli juice. The three appliances used to extract juice were slow juicer 80 revolutions per minute (rpm), centrifugal juicer at 15,000 rpm, and hand blender. It was concluded that broccoli juice made using the slow juicer produced higher antioxidative, anticancer, and anti-diabetic functional aspects when compared to those made using the centrifugal juicer and hand blender (Lee et al., 2013).


In a 2014 study (no reported conflicts of interest), the changes of quality in fresh fruits and vegetable juices when made using various juicers was studied. Slow juicers produced the freshest juice in terms of the juice quality as well as a high yield (Choi et al., 2014).


Some nutritional tests ran by Hurom using Michelson Laboratories, Inc., Korean Food Research Institute (KRFI) and internal labs showed that Hurom slow juicer had a 35% extra juice yield as compared to traditional juicers.


Regardless whether they are from a traditional juicer or cold-pressed juicer, juicing makes a refreshing drink. However, fruit juices can make it easy to exceed your sugar intake, so the best way is to enjoy fresh cut fruits, to keep your sugar intake moderate while ensuring you get a higher amount of beneficial nutrients such as dietary fibre, antioxidants and vitamins.


Therefore, if you are considering making juicing a part of your lifestyle, do remember to have more vegetables than fruits in your combos to prevent an excessive intake of sugars. If using a traditional juicer, non-leafy vegetables instead of leafy ones should be used. Traditional juices are unable to extract much juice from them as compared with slow juicers. Include juices in your diet occasionally if you wish, and remember to opt for fresh fruits and vegetables when possible.
