Frequently Asked Questions
What is miso?
Miso is a traditional Japanese fermented paste made from soybeans, salt, and koji (Aspergillus oryzae), sometimes with added rice or barley. The fermentation process produces probiotics, bioactive isoflavones, and enhanced nutrients that support digestive and overall health.
How much miso should I consume daily and is it safe?
A typical serving is 1-2 tablespoons (15-30g) per day, commonly as miso soup. Miso is generally safe but is high in sodium (600-900mg per tablespoon), so those on sodium-restricted diets should moderate intake. Avoid boiling miso to preserve its probiotic content.
What are the main health benefits of miso compared to other fermented foods?
Miso provides a unique combination of soy-derived isoflavones, live probiotics, and enhanced mineral bioavailability from fermentation. Unlike many fermented foods, miso also delivers complete plant protein and vitamin K2. Japanese epidemiological studies associate regular miso consumption with improved gut health and potentially reduced cardiovascular risk.
