Introduction to Nutrition

Genetically Modified Food

Foods developed from organisms whose DNA is changed by applying methods of genetic engineering is known as Genetically Modified foods. Such techniques allow control over food’s generic structure and introduce new crop traits.

Example

There is several genetic modified food, some of them are given below:

• Pesticide resistant rape plants
• Golden rice
• Long-lasting tomatoes
• Soybeans
• Vaccination banana

GM foods are derived from organisms whose DNA has been modified artificially, these crops are to improve yield by providing resistance to plant diseases. In future, genetically modified foods will alter the nutrient content of foods by reducing it allergic portion or improving the efficiency of food production systems.

The main health concerns for new genetically engineered food revolve around being allergic or toxic through the engineered process. FDA reports that foods they have evaluated till now are not likely to cause an allergic or toxic reaction (McFadden, 2014).

Nonetheless stomach sections presented reasonable erosive/necrotic lesions in seven female rats but no one in the panels but no histology was done as these were deliberated to be of no prominence. Even though in senior humans who used aspirin to prevent thrombosis, this can cause life-endangering hemorrhage (Kok, 2014).

Benefits of GM food

Some opportunities to use GM foods for good are:

• Better resistance against weeds, pest and other diseases; such as corn
• Corn is widely grown and an essential grain in the United States.
• Corn cannot be reproduced without human aid.
