Do you think natto is good for you? Harvard study wants to know - anonymous survey, 10–15 minutes

A physician and faculty member at Harvard Medical School / Brigham and Women's Hospital is conducting an IRB-approved anonymous survey on perceptions of natto's (fermented soybeans) health effects.

The survey explores how people form beliefs about natto's health benefits — including the role of cultural background, information sources, and prior eating experience. It includes separate tracks for regular consumers, lapsed consumers, and people who have heard of natto but never tried it, so there's a path for most people.

Who should take this: Anyone who has eaten natto at least once, OR who is aware of natto but has never tried it. All nationalities welcome — Japanese, Japanese-diaspora, and non-Japanese respondents are all central to this research.

Time: Approximately 10-15 minutes depending on your natto experience.

Anonymous: No names, emails, or IP addresses collected.
