Centrifugal juicing does not remove a fixed percentage of the nutrients in every fruit or vegetable. Claims that the juice retains exactly 85 percent, or loses exactly 15 percent, are not a sound way to compare juicers. The result depends on the ingredient, the nutrient measured, the equipment and storage.
What Happens During Juicing?
A centrifugal juicer shreds produce and separates juice from pulp using a spinning filter assembly, as shown in Breville’s centrifugal juicer instructions. A slow juicer crushes and presses produce through its extraction system. Both separate parts of the original food, so neither produces a drink identical to eating it whole.
Juicing exposes cut ingredients to air, and storage conditions can affect some compounds. However, motor speed alone does not establish how hot the juice becomes or how much of a nutrient is lost. That requires measurements, not an assumption that fast blades destroy nutrients.
Does Cold-Pressed Juice Always Have More Nutrients?
Do not assume that every cold-pressed juice contains more nutrients than a centrifugal juice. A useful comparison needs to identify the produce, machines, nutrient measured and storage conditions. A fixed nutrient-retention percentage cannot describe every combination.
Likewise, no foam, zero oxidation and a guaranteed higher yield should not be assumed from a juicer’s category. Compare evidence for the actual machine and produce if those features matter to you.

What About Fiber?
Separating and discarding pulp reduces the fiber you consume compared with using the edible whole fruit. USDA distinguishes juice from whole fruit. A blender generally keeps the pulp in the drink unless you strain it. Neither method makes inedible pits or unsafe ingredients suitable to consume.
What Should You Consider When Choosing a Juicer?
Consider the produce you will use, preparation required, cleanup, capacity and whether you prefer some pulp. Do not pay for a machine solely because of an unsupported nutrient-retention percentage.
Prepare produce and clean the equipment as instructed. Home-extracted juice is not pasteurized merely because it is cold-pressed. Refrigerate it promptly, and remember that people at higher risk of foodborne illness should choose juice treated to kill harmful bacteria.
