Introduction

Drew Tarmey Assessment J(2) Research into Genetically Modified foods is Essential to the Survival of an Ever Increasing human Population, Discuss Genetically Modified Foods Or GM Foods as they are often called, have sparked much recent debate and to a large extent, criticism from the general public. In reality only four main constituents have been affected by the introduction of GM foods. Cheese: Recombinant Chymosin to coagulate milk Maize: Recombinant Bacillus Thuringiensis gene to damage the guts of insect pests Soya: `Roundup Ready? ` to resist glyphosate herbicide Tomatoes: `Flavr Savr?` to delay spoilage and enhance taste Table: The Biochemist P32 October 1999 ? 1999 The Biochemical Society In general crop plants are being modified genetically for reasons such as: Increased shelf life, Increased flavour, move vivid colouring, resistance to agricultural control chemicals, herbivores and diseases. In 1998 world-wide 28 million hectares of land was devoted to the growing of transgenic crops. Landmarks In Public Awareness of Crop Genetic Modification The first transformed plants to be reported were tobacco plants in 1984. The event was seen as enormously significant in scientific circles but generated little public interest. The first GM plant field experiment in the U.K. was assessed by the then developing regulatory machinery in 1987. ...read more.

These will include, for example, soy products with improved flavour, digestibility and obvious gains for healthy eating, including a reduction in the cholesterol levels of consumers. There will be novel oils, soy milks, and soy flours with beverage, food, meat and industrial benefits, possessing reduced anti-nutritional compounds and refined proteins and oils, such as high oleic soybean with 30 percent less saturated fat and zero ''trans'' fats. Soybean margarine will also become a possibility, with the combination of high stearic beans and high oleic beans. Dennis. A. - benefits of GM Food - http://www.probiotech.com/artic01679.html Demanding proof that genetically modified foods are safe is all very well, but without a rational system for testing conventional foods, we may never get it Benefits and Concerns Earlier this year, Britain was rocked by claims that genetically modified foods are dangerous. Arpad Pusztai, a biochemist who used to work at the Rowlett Research Institute in Scotland, said he had shown that GM potatoes were harmful to rats because of their genetic modification alone. Were the GM potatoes toxic? On the basis of Pusztai's evidence, it's impossible to say. In fact, his results support only one obvious conclusion: rats hate potatoes. Pusztai fed separate groups of rats on normal or GM potatoes to see if the GM food had different effects. ...read more.

Conclusion

This process gives them a greater shelf life and means they are less prone to bruising when in transit. They are also less likely to lose their colour and more importantly, retain more of their nutrients. This ultimately gives consumers a better product and reduces the amount of waste for the producers and retailers. Proteins vital to our diets can be added to foods which don't ordinarily contain them, which is important for people lacking them. In time, this will also be true of vitamins, minerals and other nutrients. http://www.futuradesign.co.uk/gm/ With respect to the information I have studied herein I conclude that genetic modification of foods is not without some induced risk as totally alien genes are being inserted into organisms from unrelated species. This has been shown to possibly alter the new organism's `properties` as a food substrate either beneficially or adversely. I believe that GM foods have great potential in providing food for an ever increasing population where more traditional agricultural techniques may struggle to cope or fail. However, efficient regulation of the market is necessary and the proactive techniques which have developed to meet this demand may have played a significant part in public rejectance of GM techniques in some countries. ...read more.

    ?Darwinius masillae represents the most complete fossil primate ever found, including both skeleton, soft body outline and contents of the digestive tract. Study of all these features allows a fairly complete reconstruction of life history, locomotion, and diet. Any future study of Eocene-Oligocene primates should benefit from information preserved in the Darwinius holotype.
