While all juicers require scrubbing, we wanted to find the models that were as simple to clean as possible, free of nooks and crannies where pulp could collect. Despite a reputation that cold-press models will have you digging pulp out of their components for hours, our testing found that they were only slightly more difficult to clean than the centrifugal juicers.
However, considering that it’s the compensation for healthier, more nutritious juices, the 2 minute wait is not exactly a deal breaker. Plus, since the juice is cold-pressed and is exposed to very minimal oxidation, it can be stored up to 72 hours in the fridge. That means you can actually save more time than using a fast juicer, since the juices made with fast machines typically degrade within a couple hours after they’re made.
Juicing is a unique way to naturally process your fruits and vegetables to maximize the nutrition you get from your foods. By chopping, crushing, and squeezing fruits and vegetables, you are helping to release all the micronutrients found within the cell walls  These micronutrients are very beneficial to your health and can benefit nearly every aspect of your health. Simply put, Juicing is good for you! One of the most effective means to ensure you are getting the most of these powerful enzymes and micronutrients is to juice with a high-quality juicer made just for juicing! Research has shown that using juicers, rather than blenders, is a much more effective way to release natural anti-oxidants found in fruits .
The major disadvantages of this type of machine are the noise, heat, and oxidation resulted from their great speed. This oxidation can cause a loss in nutrients in the juice, thus reducing the juice quality and fridge life. Besides, while they’re good for thick, hard, crunchy fruits and veggies, these juicers are much less efficient in handling leafy greens.
Everyone from Wall Street bankers to Beyoncé is talking about juice cleanses, but registered dietitian Emily Braaten urged us to be wary: “There is no substantial scientific evidence to support the use of freshly squeezed juice for ‘cleansing’ purposes. Humans rely on the liver and the kidneys to separate out potentially toxic byproducts of metabolism.” The National Institutes of Health (NIH) point out that each of your kidneys “is made up of about a million filtering units” that remove about one to two quarts of waste and extra fluid a day via your urine. In other words, your body already has the whole detox thing covered.
Low foam production: The foam that accumulates on top of your juice is a good indicator of how much air has been whipped into your juice by the machine, and more air exposure equals more oxidation. Oxidation is a controversial topic. As Harold McGee explains in On Food and Cooking: The Science and Lore of the Kitchen, “Because juicing mixes together the contents of living cells, including active enzymes and various reactive and oxygen-sensitive substances, fresh juices are unstable and change rapidly.” So the prevailing theory among juicers is that if less oxygen is whipped into a juice, the valuable nutrients and enzymes remain more intact. But as Kohler told us, there’s not much peer-reviewed research on how or if oxidation affects the nutrient contents of your juice. “It’s all manufacturers’ data for the most part,” he said, “which I take with a grain of salt.” That said, we still prioritized machines that produced less foam, because at the very least, oxidation can cause your green juice to turn brown, and may lead to some muddy, off flavors.
Another important consideration is where you plan to store your juicer and how easily you’ll want to access it. While horizontal-masticating juicers can churn out high volumes of juice, you may not have space for them. Plus, they tend to weigh more so tend to be difficult to move from closet to counter. The small footprint of vertical juicers is ideal for smaller kitchens with limited counter space and can often tuck under cabinets. Lightweight centrifugal models are perfect if you need to move your juicer from storage space to counter. Just make sure whatever model you pick can handle the volume of juice you plan to make: smaller juicers equal smaller amounts of juice per batch.
