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.
Juicing isn’t for everyone. Registered dietitian Sylvia North warned us that “if you have a clinically diagnosed inflammatory bowel or kidney disease, some nutrients found in high concentrations in green juices may not be appropriate.” If you’re navigating any health challenges, it’s best to talk to your registered dietitian or doctor before you shop for a juicer.
The flavor of the Tribest juice was as fresh and bright as any I’ve had at boutique juice bars, with a nice balance between the kale and the grapes. The hue was a vibrant green, like Technicolor in a glass. The foam was minimal, too, measuring half an inch above the top of the surface of the juice; lesser juicers had up to four inches of foam at the top. The Tribest also handled 21 ounces of hard and fibrous vegetables and fruits like a champ. In our 2015 testing, the carrot-apple-celery-ginger juice yield was 15.3 ounces, the second-best result of all the models tested.
Lemons and oranges should be peeled unless one wants to consume all those antifungal sprays that are sprayed on many citrus prior to storage. Even DIY home grown organic peel with no chemicals will spoil the taste just because citrus oil in peels is too strong for consumption in quantities – this is why some supermarket citrus juices have this wonderful smell combined with some bitter aftertaste. Citrus oil is good to flavour cakes and treat pimples, but not for drinking.
Centrifugal: This is the most common type of juicer sold at kitchen stores and big box retailers. It’s the most affordable. Once you feed in the vegetables or fruit, it shreds and spins very fast so that the pulp and bits of fruit and vegetables are caught by a strainer or filter and the juice spins out. Centrifugal juicers can be loud. And, because they are fast, they heat up, which can affect the nutritional value of the juice.
Then we repeated our tests with hard fruits and vegetables, using 8 ounces each of carrots and apples, 4 ounces of celery, and 1 ounce of ginger. In 2015, we tested our three picks against new contenders: the Kuvings Silent Juicer, Juicepresso Platinum, Tribest Solostar, and Omega NC800. We searched for new and notable models from 2017 and 2018 for this update, but didn’t find any worth testing.
Auger-style juicers, sometimes referred to as masticating or cold-press juicers, crush and mash the produce. They're typically more expensive, and can also take some getting used to as the augers can jam when grinding tough fruits and veggies. For this reason, every one we tested has a reverse button. The upside with this style is they tend to leave more healthful and fiber-rich pulp in the juice.
