“…In short, the controversy about the health safety of GM foods is complex. Good science and its communication are required in order to find solutions (Magana-Gomez and delaBarca, 2009). If combining and analyzing recent findings on reproduction of male and female animals fed daily diets containing GM crops show significance; this may indicate unintended effects, which then certainly would require further scientific investigation to answer safety concerns.…”

“…Then, the resulting plants can express the novel and desirable traits, such as enhanced disease resistance, anti-reversion force or secretion of useful proteins during different stages of the plant growth. In these plants, the genetic insert leads to the production of a gene product, which does not interfere with the overall metabolism of the plant cell, and does not alter the composition of the GM plant except for the introduced trait (World health Organization (WHO), 2002; European Food Safety AuthorityGenetically Modified Organism (EFSA GMO) Panel, 2008;Magana-Gomez and delaBarca, 2009;Dhlamini, 2009). With many advantages over conventional crops, GM plants are now under development and rapid commercial use since 1996.…”

In the past few years, genetically modified (GM) crops aimed at producing food/feed that became part of the regular agriculture in many areas of the world. However, we are uncertain whether GM food and feed can exert potential adverse effects on humans or animals. Of importance, the reproductive toxicology of GM crops has been studied using a number of methods, and by feeding GM crops to a number species of animals to ensure the safety assessment of GM food and feed. It appears that there are no adverse effects of GM crops on many species of animals in acute and short-term feeding studies, but serious debates of effects of long-term and multigenerational feeding studies remain. The aims of this review are to focus on the latest (last 3 to 4 years) findings and debates on reproduction of male and female animals after feeding daily diets containing the GM crops, and to present the possible mechanism(s) to explain their influences.

“…Approximately half the world's population lives on a daily bowl of white rice, containing no vitamin A. Enabling rice more nutritious, could improve people's lives enormously [64]. Besides, bioavailability of the carotene from golden rice has been confirmed and noticed to be an effective source of Vitamin A for human systems [65,66].…”

Biotechnological discoveries and inventions have been observed to improve food production qualitatively as well as quantitatively. In certain specific cases, the improvement in the quality and nutrition of foods by altering their composition were also monitored. However, the practice of biotechnology has also upraised concerns about its potential risks to the environment as well as human being. Genetic Engineering provides resources to host genes into plants via mechanisms, different in some respects from classical breeding. A number of genetically engineered variety of foods have been developed, which have become important nutraceuticals; most notably canola, cotton, maize and soybean, were developed employing this modern technology, and at present the traits introduced are herbicide and/or pest tolerance. Gene technology leads to increase the production in plants, as well as the elevation of resistance to pests, viruses, frost, etc. Gene transfer technology is employed to alter the physical and chemical composition with nutraceutical worth. The present review article is the compilation of various physiological and biochemical studies reflecting both positive and negative ecological concerns of genetically modified foods.

Abstract:Biotechnology offers a variety of potential benefits and risks. It has enhanced food production by making plants less vulnerable to drought, frost, insects, and viruses and by enabling plants to compete more effectively against weeds for soil nutrients. In a few cases, it has also improved the quality and nutrition of foods by altering their composition. However, the use of biotechnology has also raised concerns about its potential risks to the environment and people. For example, some people fear that common plant pests could develop resistance to the introduced pesticides in GM crops that were supposed to combat them. Genetic engineering provides a means to introduce genes into plants via mechanisms that are different in some respects from classical breeding. A number of commercialized, genetically engineered (GE) varieties, most notably canola, cotton, maize and soybean, were created using this technology, and at present the traits introduced are herbicide and/or pest tolerance. Gene technology enables the increase of production in plants, as well as the rise of resistance to pests, viruses, frost, etc. Gene transfer is used to modify the physical and chemical composition and nutritional value of food. Gene transfer in animals will play a part in boundless possibilities of improving qualitative and quantitative traits. The yield, carcass composition and meat characteristics the use of nutritive substances ? not sure what is being said here?, and resistance to diseases can be improved. On the other hand, negative effects of gene technology on animals, human, and environment should be considered. The present review article is the compilation of various studies that present both positive and negative impacts of genetically modified food on human health.
