Are soyfoods a good fit for people with high blood pressure? Absolutely.

Low sodium soy products such as unsalted edamame, roasted (unsalted) soy nuts, soy milk, tempeh and tofu can make important contributions to heart-healthy diets.

Multiple components of soybeans may have blood-pressure lowering effects.  For example, digestion of soy protein may produce small chains of amino acids, the building blocks of protein, that lower blood pressure.  And compounds in soybeans called isoflavones, appear to boost the activity of enzymes that increase the production of nitric oxide, a molecule which widens blood vessels and reduces blood pressure.1
