A study from Johns Hopkins University found that soy sauce allergies are more common than we might think.
According to the report, one in three people in the US is allergic to soy sauce.
Researchers say this is probably due to the soy sauce used in the country’s dishes.
“Many Americans do not know that soy products are made from plants, and that their use is linked to allergies to other plant foods, including soybeans, peanuts, and wheat,” the study’s lead author, Dr. Anette Leavitt, told CBS News.
“The soy sauce they’re eating is often genetically modified, and has been for decades.”
The study looked at the reactions of 10,834 people who were randomly assigned to either the soy milk allergy or the milk allergies group.
“We wanted to know how people react to soy milk, whether they were sensitive or not, and whether they had reactions to soy-based products,” Leavett said.
“We found that people who had been exposed to soybean-based soy sauces were significantly more likely to have soy sauce-induced allergies.”
While people may not be aware that soy milk is derived from soy, it’s still possible for some to have a reaction to it.
“One of the things we found in the study was that a significant number of people who did not have soy milk allergies were actually allergic to other soy-containing foods,” Leivitt said.
“So they might be allergic to wheat, for example, or to the sugar in peanuts.
So it’s important to understand that not all soy products can be a cause of an allergy.”
Leavitt says that people should check with their doctor about whether they have a soy allergy, because it can take weeks or even months to find out.
“I think a lot of people don’t realize the severity of the reactions that they might have,” she said.
The study was published in the Journal of Allergy and Clinical Immunology.
