Low in calories and high in vitamins, spinach is one of the most nutrient-dense foods. This leafy green is home to many phyto-nutrients that have health promotional and disease prevention properties, including vitamins K, A, B6 and B1. Spinach leaves also contain a good amount of minerals like potassium, manganese, magnesium, copper and zinc.
Look for bright green, fresh tender leaves. Avoid spinach that is yellowish or wilted and gritty. Refrigerate in crisper.
