Genetically modified animals

Benefits of organic food has been harped upon by many nutritionists, though many believe that the benefits of organic food is far greater than conventional foods it still stands as a perception more so than theory , however this does stand strong amongst many and perhaps the main reason behind the increased demand for organic food stuff.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 Agricu ltural 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 as well Genetically modified animals.Apart from aiding the development of the medical sciences genetically modified animals are also taking the food and farming industry by storm. For instance, cows can be enhanced to produce more milk, pigs to create leaner bacon and sheep that are able to produce larger quantities of wool. These genetic modifying techniques can also be used effectively to create animals that are resilient to certain diseases that can pass on to humans.

Due to the changes in climate, such as coldness, farmers are not able to do farming during certain periods of the year. Most of the foods do not tolerate extreme weather or climate changes, so as a result, crops may produce low volum es. In order to address this, genes of the plants that can withstand coldness have been added to the food producing plants, making the latter category more cold resistant. This is one of key benefits of genetically modified foods. As another benefits of genetically modified foods, in some other countries, paddy has been developed genetically where they can withstand low water supply. Water is one of the burning issues in some of the developing countries.
