The Plant Protein Nutrition Guide (Beans & Tofu)
Natto
* Bacillus subtilis–fermented whole soybeans. Unlike tempeh, usually eaten without further cooking — still not a quantified CFU probiotic claim.
Benefits & risks
Fermented
benefit · compound
Bacillus subtilis fermentation of whole soy. Typically eaten without a second cook (unlike tempeh) — still not a lab CFU / yogurt-style live-culture count. Eligible for a recipe bonus when Methods publishes the weight.

Vitamin K2 (MK-7)
benefit · compound
Natto is widely cited as a rich natural MK-7 food. USDA SR reports total vitamin K as phylloquinone on this row — MK-7 is the fermentation story from the literature, not a separate USDA composition cell. Display-only until Methods publishes a weight.

Empty cells mean we do not yet have a method-cited source. Rank on the guide tables is the open-rule champion — not medical advice.
