What’s the controversy over GMO foods?

This post will give a general overview of GMO foods and the controversy surrounding them. GMO stands for genetically-modified organisms, and describes the technology used to manipulate DNA and create genes in foods that do not occur naturally. Bioengineers of these foods claim numerous benefits to genetic modification, including reduced use of pesticides, increased yield of crops, and economic and environmental benefit (due to decreased use of pesticides).

Dr. Kathy Gruver, a health and wellness expert who holds a PhD in natural health, states that GMO’s pose numerous potential risks. One of the biggest concerns is that consumers become a type of “experiment”, as it is not known what health effects these foods will produce, and it is in the hands of food companies to decide whether these products are safe. Additionally, because DNA differs from person to person, consuming food that has been genetically modified adds to the unpredictability of its effects on humans. Dr. Gruver also mentions that in-vitro studies have shown that GMO’s have the potential to increase allergies and resistance to antibiotics. Another problem with having farms and fields of GMO foods is that animals or natural forces (such as wind) can transport the seeds produced by the crops, causing them to unknowingly grow anywhere.

It is estimated that about more than 75% of all soybeans, over 50% of cotton, over 25% of corn, and 25% of canola worldwide is genetically modified, and as a result, about 75% of processed foods in the U.S. has some sort of genetically-modified ingredient. There are no regulations that require food manufacturers to list genetically-modified ingredients on their labels, therefore the general public may be unaware that they are consuming these foods.

The Non-GMO Project divides these food products into two groups: high risk and monitored risk. Alfalfa, canola, corn, cotton, papaya, soy, sugar beets, zucchini and yellow summer squash are among high risk crops. Monitored risk products are suspected to have GMO’s, and include chard, beets, rutabaga, bok choy, turnip, acorn squash, flax, rice, and wheat. Additionally, meat products from animals that consume these crops may contain GMO’s.

  1. Very informative post! I have always wanted to learn more about GMO’s and you have explained it very well here. It would be nice to see more research completed to see if there are long-term effects from eating GMO’s. Unfortunately, the key word is “long-term” where we have to wait to see results. When companies are looking for a good bottom-line now, the health effects get lost in the shuffle. I have seen more and more information about Monsanto Foods (the main seed supplier in the U.S.). Here’s the Snopes website information about the Monsanto Protection Act: http://www.snopes.com/politics/business/mpa.asp.

    Thanks for a great blog post!

  2. You are so right that we have been used as an experiment with GMO’s. I would love to go into the future and see what types of findings they will eventually find…..and sadly, thanks to Monsanto, there will probably be little we can do to get back Non-GMO foods. I wish more people were aware of GMO’s. I don’t think the older generations are even aware that they are not eating real food, but a science experiment.

    I’m going to have to look into the non-GMO shopping guide! I would have never thought there would be such a thing! Good post :)
