A food allergy to soya is one of the most common causes in infants, young children, and adults. A soya-free diet removes soybeans and all products derived from soybeans. Most people who are allergic to soya are allergic to the protein in soya. Soya oil and soya lecithin pose little risk of causing an allergic reaction in most, although not all soya-allergic people because processing removes almost all the protein.
The Symptoms involved when being allergic to soya involve skin rashes or ‘hives’, gastrointestinal distress, breathing problems, and there is many other possible symptoms. In severe cases, a life-threatening reaction called anaphylaxis may occur, although such a severe reaction to soya is very rare.
To avoid soya and soya products ask about ingredients at restaurants and others’ homes, read food labels( Soya is known as one of the most common allergies so by law in the EU products have to state on their labelling if they contain soya or not), and become familiar with the technical or scientific terms for soya. Also consult with a healthcare professional before making any significant changes to your diet.
