_*There are organic foods companies*_



These days, many people are aware of GM foods, so there are quite many organic foods companies. They show the processing how they grow the foods and even delivery to homes and offices as well as recommend fresh organic foods. Here are several organizations or companies for organic foods.
1. RODALE INSTITUTE - Eat organic & Be healthy (Learn how eating organic foods will increase your health!)
2. Farm Fresh To You - Organic produce delivery (Organic & Seasonal Fruits, Greens & Vegetables Delivered To Your Door.)
3. Earth Share - Tips for eating organic (Simple tips to eat well and save money.)
4.
Whole Foods Market - Whole Foods Market is the world's largest retailer of natural and organic foods, with stores throughout North America and the United Kingdom.
5. American Farmland Trust - Support your local organic farms. Help save local farms & farmland.
6. Earth's Best - Give your baby the best with Earth's Best Organic baby food.
7. Amy's Kitchen - Amy's organic offerings include frozen whole meals such as organic enchilada verde and kids' meals such as baked ziti, as well as salsas and pasta sauces, soups, burritos and even desserts.
8. Green&Black's - Green & Black's produces some of the world's most decadent organic chocolate.
9. 365 Everyday Value/Whole Foods - Whole Foods Markets strive to exceed their customers' expectations and offer the highest quality natural and organic products available.
10. Organic Valley - Organic Valley is a cooperative of 1,326 farm families who produce premium, market-certified organic food products.

_*Here are many kinds of GM foods*_

These days, around us there are many kinds of GM foods, and we eat them. Some of them are made for convenience of eating such as seedless watermelon and grape, but some of them have a lot of harmful components. Before eating any foods, I think we should know that foods are GM or not. You should keep in mind these following foods are GM foods. Here are some kinds of GM foods!!

_*The Method and Development*_

{Method}

Genetic modification involves the insertion or deletion of genes. In the process of cisgenesis, genes are artificially transferred between organisms that could be conventionally bred. In the process of transgenesis, genes from a different species are inserted, which is a form of horizontal gene transfer. In nature this can occur when exogenous DNA penetrates the cell membrane for any reason. To do this artificially may require attaching genes to a virus or just physically inserting the extra DNA into the nucleus of the intended host with a very small syringe, or with very small particles fired from a gene gun. However, other methods exploit natural forms of gene transfer, such as the ability of Agrobacterium to transfer genetic material to plants, and the ability of lentiviruses to transfer genes to animal cells.



{Development}

The first commercially grown genetically modified whole food crop was a tomato (called FlavrSavr), which was modified to ripen without softening, by Calgene, later a subsidiary of Monsanto. Calgene took the initiative to obtain FDA approval for its release in 1994 without any special labeling, although legally no such approval was required. It was welcomed by consumers who purchased the fruit at a substantial premium over the price of regular tomatoes. However, production problems and competition from a conventionally bred, longer shelf-life variety prevented the product from becoming profitable. A variant of the Flavr Savr was used by Zeneca to produce tomato paste which was sold in Europe during the summer of 1996. The labeling and pricing were designed as a marketing experiment, which proved, at the time, that European consumers would accept genetically engineered foods. Currently, there are a number of food species in which a genetically modified version exists.

_*Survey about GM products*_

I surveyed about GM products in my English class. After getting resulting, I was quite surprised about the opinions of my classmates. Because they didn't know much about GM products, and most of them thought that we need the products, the survey result made me reconsider about the GM foods. More survey questions and answers are here~~ Survey

_*What's GM foods?*_


GM food is...

Genetically modified (GM) foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding (plant breeding and animal breeding), and somaclonal variation.

GM foods were first put on the market in the early 1990s. Typically, genetically modified foods are transgenic plant products: soybean, corn, canola, and cotton seed oil. But animal products have also been developed. In 2006 a pig was controversially engineered to produce omega-3 fatty acids through the expression of a roundworm gene. Researchers have also developed a genetically-modified breed of pigs that are able to absorb plant phosphorus more efficiently, and as a consequence the phosphorus content of their manure is reduced by as much as 60%.

Critics have objected to GM foods on several grounds, including perceived safety issues, ecological concerns, and economic concerns raised by the fact that these organisms are subject to intellectual property law.
