The US Department of Agriculture warns against relying on juice as your sole source of nutrition. This kind of diet won’t give you enough protein or fiber to maintain muscle mass and keep you feeling full. When we spoke with nutritionist Shereen Lehman, she reiterated this point. “Juicing alone won’t fix an unhealthy diet,” she told us. “It’s also important to cut out the junk foods and eat more lean protein sources, dairy or calcium sources, whole grains, and more fruits and veggies.”
The best juicers extract as much liquid as possible from fruits and vegetables, leaving behind very little pulp. Machines that leave large amounts of very moist pulp just aren’t doing their job. The same is true for froth. Every juicer makes some froth, but you don't want inches of bubbles – you want a machine that gives you the most juice for your money.
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.
