Genetically modified(GM) foods – are they safe or harmful? While regulatory authorities have approved GM food that is on the market, some people are concerned that there is a risk of harm. Most foods we eat may contain ingredients derived from genetically modified organisms (GMOs). If you live in Europe, avoiding GM foods is easier since laws require labelling. In the US and Canada, however, food manufacturers are not required to label if their food is genetically modified or not. Here are some guidelines for steering clear of GM foods in your diet, if that is your choice.
