Some of the team's findings include:

Food allergy or intolerance were documented for 3.6 percent of the population studied
Shellfish was the most commonly reported food allergy
The highest rates of food allergies or intolerance were among females and Asians
The multidisciplinary team, including a medical student, Warren Acker; an allergist, Kimberly Blumenthal, MD, MSc; patient safety experts and informaticians, used food and allergy intolerance data collected at Partners HealthCare between 2000 and 2013, including information from multiple community and specialty hospitals as well as community health centers. The team examined data on culprit foods, reaction(s) to that allergen, date/time of the reaction and more. The research team used the term "food allergies and intolerances" to include any adverse reaction to food (such as hives, anaphylaxis, shortness of breath, wheezing, itching, swelling and more) as well as pseudoallergic reactions, intolerances and even food preferences reported in the health record.

The team looked at a variety of food allergens, finding that almost 13,000 patients had a reported allergy or intolerance to peanut, including more than 7,000 (56.5 percent) who had hives, anaphylaxis, or other potentially IgE-mediated reactions. To better understand the validity of the food allergy data they examined, they looked at specific antibodies produced in response to peanut via the radioallergosorbent test (RAST) or ImmunoCAP test for all patients who reported a peanut allergy.

The overall rate of allergy prevalence that the team found -- 3.6 percent -- is consistent with previous estimates using oral food challenges.

The team also notes that food allergies are quite common
