You may have heard that natto is an outstanding food for building and maintaining bone mineral density, especially as it relates to that very important micronutrient, vitamin K2. But what exactly is natto? It is cooked soybeans that are inoculated with a special “starter” and then fermented. Unlike other fermented foods, natto does not develop a “sour” taste, but rather a strong, distinctive smell and flavor. They also develop a “slimy” texture.
What does it taste like? Some liken it to salty cottage cheese, foie gras, or old Brie. Anthony Bourdain once proclaimed natto to be “the Vegemite of Japan,” and had a colorful description of his reaction to it. That said, natto is a popular breakfast food in many parts of Japan and it has some pretty extraordinary health benefits.
How is natto served up? Usually with rice, soy sauce, karashi mustard and thin sliced onions. Where can natto be purchased? At many health food stores and online retailers. I’ve even seen it at mainstream grocers like Safeway or Fred Meyer.
