Genetically Modified Food Really God-made?

Genetically Modified Food Really God-made?

Consumers frequentl y asi k what is in it for e?>

Consumers frequently ask, “what is in it for me?”

hat are GM organisms? Genetically modified organisms(GMOs)can be defined as organisms in which the genetic material (DNA) has been altered in a way that does not occur naturally It allows selected individual genes to be transferred from one organism into another, also between non-related species GM Products (current or those in development) include edicines and vaccines, foods and food ingredients, feeds and fibers

Why are GM foods roduced? GM foods are developed-and marketed because there is soe perceived advantage either to the producer or consuer of these foods. This is eant to translate into a product with a lower price, greater benefit(in terms of durability or nutritional value) or both Increase crop protection through the introduction of resistance against plant diseases caused bi insects or viruses or through increased tolerance towards herbicides: 1) insect resistance 2) virus resistance 3)herbicide tolerance

The potential for GM seeds toesurcmoggergea per cultivated area should lead to lower prices. However, public attention has focused on the risk side of the risk benefit equation

The potential for GM seeds to result in bigger yields per cultivated area should lead to lower prices. However, public attention has focused on the risk side of the risk￾benefit equation

Main concerns for human health e potential rIS chuan health involves 1)direct health effects(toxicity) 2)tendencies to provoke allergic reaction(allergenicity); 3)specific components thought to have nutritional or toXIc properties; 4)the stability of the inserted gene; s)nutritional effects associated with genetic modification 6)any unintended effects which could result fro the gene insertion. The three main issues debated are tendencies to provoke allergic reaction (allergenicity), gene transfer and outcrossing
