Natto offers a unique probiotic boost to our immune system. The Japanese have consumed fermented soy for centuries and continue to this day. Is it any wonder they continue to top the list of the world’s healthiest countries?
Wondering about the toxic reputation of soy? In its natural state, soy contains anti-nutrients that are toxic to humans. The fermentation process neutralizes these, transforming the soy into a beneficial and immunity-boosting food.
Are you concerned about the goitrogens present in soy? Goitrogens, thyroid inhibitors, are not neutralized during fermentation. In fact, they are increased. Some suggest foods high in iodine while consuming natto. Others advise fermenting alternate beans such as navy beans. Others recommend keeping your natto consumption to a minimum. Since 40 grams of natto contains 500% of the RDA for Vitamin K2, it makes sense to limit natto consumption and keep it as a condiment.
Vitamin K2 is one of the outstanding benefits of natto. See Vitamin K2 and Natto.
Ready to try it? If you’ve never tasted natto, be prepared for a bit of a challenge. Natto is an acquired taste. The good news is you can learn to enjoy natto. I no longer grimace when I eat it. My body craves it.
You can find natto in the freezer section of many Asian grocers. Most come with flavor packets with undesirable additives. Consider tossing the packets and flavoring with your natural condiment or dressing.
I trust and enjoy the brand megumiNATTO available for purchase online. Find them here.
It’s far more cost effective to make it yourself. Here is the method that works for me.
1. Organic (or certified GMO free) soybeans. Other beans, such as navy beans, may be substituted, but the soybean offers unique nutritive benefits. Sources of organic soybeans include:
2. Starter culture. Store-bought natto may be used to inoculate the soybeans, or you can purchase a starter from these websites.
3. Pressure Cooker – optional. The pressure cooker hastens the cooking time for the soybeans.
Natto starter costs less than $20 and will last for many batches. Organic soybeans cost approximately $4.00 per batch. This means natto costs pennies per serving, offering an inexpensive, power-packed boost to your immune system.
