whats in your beef- is Genetically Engineered Food a Hazard?!

Do you share the same concern if you are in EU then relax the rules stipulates that GM food should carry the label to distinguish them from the rest of the crowd. But what if that is not enough.

The website http://www.psrast.org/ gives a list that should worry any spokesperson for GM . well I am certainly concerned and not at all against GM food and GMO studies especially if it can create cheaper medicines or study drug resistance in microbes

According to Charles Saunders, chairman of the British Medical Association’s public health committee

”We simply do not have enough reliable scientific evidence on their safety to be able to make a valid decision as to whether there are potential health effects or not.

Already, an estimated 1 to 2 percent of Americans are allergic to some food, and their reactions can be serious or even fatal.

food allergies Food allergies are caused by proteins which are made by genes. Indeed, the whole purpose of genetic engineering is to force a plant or animal to make new proteins.

In one of the few pieces of hard evidence about the health dangers of genetic engineering, Stephen Taylor, who studies food allergies at the University of Nebraska, found that moving a gene indeed made a new food allergenic.

The regulatory part of the genome was two to three times larger than the portion that actually held the instructions for individual proteins.

With so much of the genome devoted to regulation, it became apparent that evolution could work by simply changing the instructions rather than changing the protein-coding genes themselves.

A tiny opossum’s genome has shed light on how evolution creates new creatures from old, showing that change primarily comes by finding new ways of turning existing genes on and off

 

 

Does the finding prove that transgenic foods are inherently dangerous? Not really

  1. It is worth putting the Taylor study in its context: the protein being moved came from a species (Brazil nut) which is known to provoke allergies, and indeed the protein moved turned out to be one of the provokers. There do not appear to be any studies suggesting that moving a protein to a new context will provoke new allergenicity, just that the old protein retains its old allergenicity. In the context of GMO food safety, that is an important distinction.

  2. Your are right its not possible for a protein to illicit a new allergenicity. If the new protein originates from a known allergenic source or its amino acid sequence is similar to that of a known allergen, the protein can be tested easily But when a new protein comes from a source that is not historically a human food we may not be sure such as bacterial genomes transfered to plants. However, evidence suggests no cause for concern about the allergenic potential of proteins from sources with no history of allergenicity, that have no amino acid sequence similarities to known food allergens, that are rapidly digested, and that are expressed at lower levels than major allergens
