What are the symptoms of a soya allergy?
soya allergy is very comon purely like corn allergy is soon going to be if it's not already..both are genetically modified foods wich are made to contain their own pesticides and be proven to have unwell effects and cause long residence health problems (allergies included). some countries do not alow ge foods but surrounded by usa and canada they don't even have to sign the foods as such. so if you want to be healthy forget soy or other foods unless they are strictly life

Please be careful. I know a immature person that died from individual allergic.
Good Luck!
