To review the maximum consumption of GM foods

Health hazards:

Allergenicity-> Proteins may be produced from the Genetic modification which cause allergies. These protein sources may originate from completely unrelated species, which led to allergies in some individuals. A good example would be the case of peanut, which is a common type of food that causes allergic reactions. If genes of the peanut is transferred into another crop, individuals who are allergic to peanuts may develop allergic reactions especially if it is not labelled on the packaging.

Gene transfer-> The transfer of genes to the bacteria of the gastrointestinal tract/ cells of body from the GM food would be a concern if the genetic material (e.g anitibiotic resistant genes) affects health.

Outcrossing-> Eating GM foods that have been given resistance to antibiotics could cause consumers to acquire antibiotic resistance as well. Some plants are injected with antibiotics to help them live longer and fight off infection.However, eating plants or animals that contain antibiotics will only worsen the conditions by introdcing more antibiotics into their systems. The higher is the level of antibiotics, the more prone people are immune to it.

Bacteria-> Bacteria in the human digestive system may collect the antibiotic-resistant genes from the GM foods. This may pose a problem as the bacteria is adapting to the anitbiotics
If bacteria pick up antibiotic-resistant genes, the already growing problem of bacteria adapting to our antibiotics will be magnified.
