Potential unintended effects of GM foods on human health

Effects of GMOs, such as increased levels of anti-nutritional or toxic components in foods have been found in conventional breeding. Agents traditional farming methods, including tissue culture, may be an option a bit 'better genetic imbalance. It is believed that the introduction of a new gene can lead to increased levels of toxicity or decreased level of nutritional value found in natural organisms. The impact assessment considered all factors it is important to avoid complications and problems of implementation of the post.

Agents and immune responses in allergy to genetically modified foods:
Food allergies or sensitivities are adverse reactions to foods triggered by the immune system. Allergic reactions to foods are well known. The main food allergens are proteins and derivatives, eggs, fish, milk, peanuts, shellfish, soy, tree nuts (almonds, walnuts, cashews and walnuts) and wheat. Considering that the most important allergens are well known and advanced test methods have been developed, traditionally developed foods are not generally tested for allergens before they are marketed.

The application of modern biotechnology crops has the potential to make food less safe if the protein is newly added cause an allergic reaction, once the food supply. protocols for assessing the risk of food allergy consists of three: (1) Evaluation of allergenicity (either food or a potential cause of food allergy) exposure assessment (2) (How likely is it that people meet the agent that cause allergies), and (3) sensitivity analysis (such as people with allergies react to this new food.)

Monitoring of human health and the environment:
In the future, GM crops can have a wider recognition for the environmental release, with or without permission to enter the human food chain. In such situations, it is important to consider whether to apply the post-marketing surveillance for unexpected environmental spread of GMOs) that may pose a risk to food safety. Methods for detection of GMOs into the environment could cause the application of two well-established body of scientific method:
(1) DNA-based diagnostic marker
(2) appropriate sampling protocols (in terms of statistical power) and cost-effectiveness.

Although GM crops have tried to solve the problems of the most powerful men say to help the food security and reduce poverty, it is necessary to make an adequate assessment of all factors negative impact of GM crops can be considered. While many scientific studies are being prepared on this matter so that a series of guidelines and standards can be developed and followed by all. This requires a careful evaluation and respectful of the interests at stake and how to balance these often conflicting interests.
