Question

Why foods derived from genetically modified crops required to be tested for possible allergic reactions in people?

• A. They may cause allergies due to release of new kind of proteins.
• B. They may not be digested.
• C. They may cause more hunger.
• D. All of the above.

Answer 1

The correct option is A They may cause allergies due to release of new kind of proteins.

The process of creating a GM crop can produce many changes in the natural functioning of the plant's genome. Native genes can be mutated, deleted, permanently turned on or off and may change their levels of protein expression. This increasing the levels of an existing protein or even producing a completely new and unknown protein within the crop can act as an allergen in consumers. Hence, foods derived from genetically modified crops are required to be tested for possible allergic reactions in people.
