The creation of genetically modified animals the altering of an animal?s genetic codes to make sure that it displays only the expected characteristics and do not possess any undesirable qualities. This is done by the addition of genes from other species, the deletion of undesirable genes or modifying the existing genes to bring certain traits forward. Though chimeras and cross breeds have been pretty much a staple in science fiction novels, nowadays, it is a wide known fact. The popular techniques to create genetically modified animals include pro-nuclear micro-injection, embryonic stem-cell manipulation and nuclear transfer. Genetically modified animals such as rabbits, cows, goats, pigs, rats, mice and cats are created with these techniques to arm them to serve their expected purposes.In the face of medical research however the increased benefits of organic food over conventional food stuff is yet to be proven, which has led the even the FDA and the USDA to claim that non organic food is just as nutritious as organic food stuff. However certain foods do carry some superior benefits of organic food, for example it has been revealed that organic milk and tomatoes are far superior to its non organic counterparts. For example organic milk is shown to contain more antioxidants and Omega 3 fatty acids and vitamins than non organic milk. These findings are according to the University of Aberdeen?s Danish Institute of Agricultural Research and the Institute of Grassland and Environmental Research, who claim that organic milk is of better nutritional quality due to the fact that the cows are pasture grazed and even .Tomatoes are the other food stuff believed to yield far superior benefits of organic food than its conventional cousin; this is according to a decade long study carried out by the University of California, Davis. Organic tomatoes are grown in an environment that has a lesser nutrient supply as nitrogen enriched chemical fertilizers are no t included. Thus because of this fact there is a greater increase in the formation of antioxidants like quercetin which there is a 79 increase and kaempferol which is 97 higher in organic tomatoes. This is essentially good news as antioxidants are vital for overall good health as they have fight carcinogenic properties such as free radicals.

Such studies have reinforced the theory that the benefits of organic food are not a mere perception and it is in fact far superior to conventional food that depends on chemical fertilizers and pesticides. The fact being that non organic food are more susceptible to be contaminated with chemical fertilizers and pesticides and more sustainable methods are overall better for ones health as well as for the environment. There again there is another school of thought that says that organic foods are harmful and the benefits of organic food do not outweigh conventional food stuff and is unsuitable for consumption as they do not us e strong fertilizer and pesticides which could result in a possibility that the food could be contaminated with harmful bacteria and parasites, despite the debate by both parties any strong or harmful impact on the health is unfounded. However the benefits of organic food is widely gaining ground and many consumers believe that organic foods have the ability to promote good health due to the lack of chemical additives and that the flavor of the food is far superior to non organic food, and definitely the more eco friendly option.
