Advocates of a raw food diet promote the use of sprouting as an effective way to increase the nutrient value, and digestibility, of beans, seeds and nuts. Sprouts are in fact the most nutrient dense food on earth [citation needed] – nutrient density refers to the amount of nutrients per calorie. This is why many people on a low-calorie diet make sprouts and baby greens the mainstay of their diet, especially blended for easier digestion.
