All About Soy-Free Diet

According to a study published in 2019, soy is among the 8 most common food allergies. A soy allergy is an abnormal response of the body to the proteins found in soy. But it isn’t that simple when it comes to this allergy as there are many forms of soy found in dressings, ready to eat meals, cereals…

This allergy often affects children. Children with a soy allergy may have nausea, vomiting, abdominal pain, diarrhea, bloody stool, difficulty breathing, and or a skin reaction after eating or drinking soy products. These symptoms can be avoided by following a soy free diet.

Studies show that most people who have an allergy to soy may eat products that contain soy lecithin and soy oils. This is because these substances are fat-based, and people with allergies react to the protein portion of the food.

Food to avoid on a soy-free diet:

If you follow a vegan or vegetarian diet, chances are that you consume a lot of soy-based products (soybeans, cheese made of soybeans, dressings..)
