Biotechnology is making great news in every filed. It is used in producing the effective therapeutic medicines and many other useful medicines which are made with natural elements. It is also used in genetically engineered foods. The new world of genetic engineering produced therapeutic foods like tomatoes and broccoli which has large amount of cancer-fighting chemical and vitamin-enhance crops of rice, sweet potatoes, and root vegetables to help and nourish the poor people. Soy, wheat and peanuts will make free of allergies. Many vegetable oils are useful to produce the useful therapeutic ingredients that doctors prescribe them for patients who are suffering from cancer and heart disease. Many biochemists believe that genetically engineered foods are the key to the next wave of advances in agriculture and health.Many professional believe that there is a great potential for Biotechnology in producing the efficient and useful medicines, but they also fear for uncertainty and dangers genetically engineered products could cause to human life. They say that people should not make a haste decision in buying them as soon as they are released in the market first they should understand the product and then take a decision in using them or not. Some products which are genetically modified may not recommended to use they may cause severe health problems to the people if they are not fully aware of the product. Many countries like North America and Europe are having a debate on using the genetically engineered food crops as they may cause severe damage to the people.Many people are not aware of consuming the genetically engineered foods; it has been in use since mid 1990s. The great country like America, where people don’t realize that they are eating these genetic foods, 60% of all processed foods have been in the market in United States of America like pizza, chips, cookies, ice cream, salad dressing etc. In the past decade or so, the Biotechnology plants that go into these processed foods have increased from nursery phenomenon to crops planted on a massive scale like 130 million acres in 13 countries. More than 50 products have passed through a federal review process and another hundred are undergoing field trials.
