It does!: Eating a fermented soybean product called 'natto, ' has been researched and shown to mildly lower blood pressure. However, it's principle benefit is to lower clotibility of blood. It is a food used for nutritional support in japan, dating back to feudal times in that country. It may help lower heart disease by several mechanisms.

It is possible.: It is possible. Nattō is made from soybeans fermented with a bacteria called bacillus subtilis. This bacteria produces an enzyme called nattokinase, which has effects similar to a class of drugs called ace inhibitors, which are used to treat high blood pressure.
