Greens with the darkest leaves are also the most nutrient-dense; opt for spinach, kale, bok choy, dandelion greens, or Swiss chard. These vegetables deliver hefty doses of bone- and muscle-building nutrients like iron and vitamin K.
The sweetness that comes from apples, melons, pears, pineapple, and citrus counters the bitterness of the greens. Compared with the refined sugar that’s added to many commercial fruit juices, fruit’s natural sugar has a gentler effect on blood sugar.
To maximize nutrition, opt for a masticating model like the Omega 8004 Nutrition Center Juicer (shown; $260, omegajuicers.com). Unlike centrifugal juicers that use a spinning blade, which can create heat and consequently destroy nutrients, a masticating juicer presses your produce to squeeze out every last drop of nutrition.
