hey!
giving my two cents worth here:
GM food are widely known to have increased nutritional value,
shorter growth period hence lower cost of harvesting. Examples are
Golden Rice which provides an additional source of vitamin A and
IR58 with a shorter growth period.
However, a drawback will be that allergens maybe present in the
GM food that poses as a threat to affected consumers. A popular
example will be lectin from beans are discovered to be found in GM
potatoes. Hence, people allergic to lectin may suffer from adverse
effects.
Please kindly correct me if I'm wrong. Hope it'll help you in
your homework^^
