I don't have any known food allergies, but it occurred to me that i've never had buckwheat before. what would i monitor as a sign of allergy?

Not to Worry: Just because you haven't tried buckwheat before doesn't put you at an increased risk for allergy. Rare to develop a food allergy later in life, shellfish/peanut more common. Food allergies are typically immediate, minutes to a half hour after ingestion of concerning food with symptoms ranging anywhere from hives, wheezing, itching, shortness of breath, wheezing, vomiting, or fainting.
