If you are thinking about a special gift this holidays you might want to look at the The Omega 8006 Nutrition Center Commercial Masticating Juicer It is equipped with a powerful commercial motor, this masticating juice extractor thoroughly chews up plant fibers to fully extract vitamins, enzymes, and minerals from fruits and vegetables. The unit’s dual-stage juicing system ensures maximum efficiency, while its low rotation speed of 80 RPMs means no foaming, no clogging, and no heat build-up. Other highlights include a high juice yield with very dry pulp, an automatic pulp-ejection function for continuous juicing, heavy-duty construction, four stabilizing feet, and quiet operation. Easy to assemble, operate, and clean, the UL- and cUL-approved masticating juice extractor measures 14-1/2 by 6-1/2 by 15-1/2 inches and carries a 15-year warranty (unlike the Breville juicer with only a 1year warranty.)

Aggregate Nutrient Density Index (ANDI) is a score assigned to whole foods that contain the highest nutrients per calorie as Dr. Joel Fuhrman describes in his book, Eat For Health.

Each of these whole foods is given a score based on the equation H=N/C, which is that the health of a food is equal to the nutrients it delivers per calorie. Each ANDI score is based on a possible score of 1,000-0, with 1,000 being the most nutrient dense and 0 being the least nutrient dense. Kale, Mustard greens, Collard Greens, and Watercress all receive a score of 1,000 using the H=N/C equation, while foods like meat, seafood, and dairy products receive scores below 50 and are not considered by Dr. Fuhrman to be healthy. Fuhrman argues in his book that a nutrient dense diet can prevent or even reverse diseases and also might reverse obesity.
