As food allergies afflict millions of children nationwide, parents and caregivers on the South Shore have been offered a chance to meet with medical experts in the field about the latest research.

Program organizer Amy Cowan arranged for 12 medical experts from food allergy programs at Boston Children’s Hospital and Massachusetts General Hospital to visit Hingham to equip parents and children with practical information about the disorder, which the US Centers for Disease Control and Prevention estimates affects 4 to 6 percent of American children.

“There is so much information out there, it’s hard to know what’s real and what’s not real,’’ Cowan said. “People want access to the doctors in an informal setting, and they also want to meet other families.’’

Although the program, to be held Tuesday, March 29, from 7 to 9 p.m. at the Wine Room at Tosca, is sold out, Cowan hopes to record the discussion and make it available for those who are interested but unable to attend.

It is being presented by the Inly School, a private Montessori-based institution in Scituate. Head of school Donna Milani Luther said Inly has been addressing food allergies since going “nut-free’’ in 1997. Some 26 percent of its students, she added, have a food allergy.

“It’s like opening a Pandora’s box,’’ she said of students receiving such a diagnosis. “Parents don’t understand it.’’

Experts in allergy research, food safety, and psychology will be available to give parents information on the latest findings, what to look for when ordering or buying food, and how to help youngsters through the internal and social struggles that can be triggered by discovery of an allergy, Cowan said.

She expects about 85 to 90 people to attend the session.
