Question

Biotechnology (Online genetic testing services, GMOs in food debate)

What are the main arguments for and against using genetically modified foods and getting DNA testing online?

Answer 1

Arguments of genetically modified foods:

For:

• Feed the world as consumers are increasing while crop land is decreasing.
• Genetically modified crops are more resistant to pests.
• Genetic modification of food improves taste and texture.
• Through genetic modification of food certain components of food can be removed (eg., trans fatty acids) and also certain food components can be added (eg., antioxidants) and hencce improved health.

Against:

• Environmental risks as long term impacts are unseen.
• Genetic modification can lead to resistance against antibiotic, increased risks of cancer, reproductive failures.
• Buisness of genetically modifed food can destroy small farmers.
• Natural food taste better than modified food.

DNA testing online:

Also known as direct to consumer (DTC) services provide detailed information of genetic make up of a person directly without physician involvement.

It gives all information related to you like status of BRCA1 gene and hence possibility of having cancer.

For:

• It gives early information regarding disease onset.
• It gives information on drug response over period of time.
• It gives information on inherited diseases or inheritable diseases.
• It gives information on paternity.

Against:

• Difficult to understand genetic information by a normal person.
• Chances of incorrect result may lead unnecessary worry in patients.
• It is just a measure of health status.
• Genetic make of certain diseases is complex, mere knowing genetic make does not give certainity.
