GMO's:Future Food or Frankenfood???

I have my own opinion about GMO’s (Genetically Modified Organisms), but for the purpose of this article, I will present both sides of the issue. First, however, let’s discuss a little of the science behind them.

Biotechnology is the field of science concerned with modifying the DNA of plants by adding or removing genes. Genetically Modified Organisms (GMO’s) are plants or bacteria which have been changed in this manner to produce certain desired traits (Schlenker & Roth, 2011). Genetic Modification is accomplished through biotechnology or plant breeding. Prior to 1990, crops were grown using traditional methods. After that time, biotechnology dramatically changed the way food was produced. Today biotechnology is used in agriculture and food processing.

The three major goals of biotechnology are:
  • Resistance to Disease and insects: Because plants that are produced using biotechnology have a built in resistance to disease and insects, fewer pesticides need to be used which is better for the environment (Biotechnology Industry Organization, 2012). Pesticides are designed to kill and therefore by their very nature pose a risk to all living organisms and the environment (U.S. Fish and Wildlife Service, 2011).
  • Increased tolerance to weather conditions: Plants genetically modified to survive in extreme weather conditions are less likely to be destroyed by late frost. This has the potential to increase crop yields and food shortages, especially in the developing world (Schlenker & Roth, 2011).
  • Increased nutritional value: Genetic modification has increased the monounsaturated fatty acid content of soybean oil and scientists are working toward increasing the lycopene content of tomatoes and increasing the protein and micronutrients of grain. This could help lessen nutrient deficiencies in developing countries (Schlenker & Roth, 2011).
The three major concerns those opposing GMO’s have are:
  • Risk of allergic reactions: Biotechnology changes the proteins in these crops and may introduce proteins which have the properties of known allergens. There is a growing body of evidence of allergies which have been caused by GMO soy and corn and even though screening for this is recommended, many of the GMO crops in our food supply fail those tests (Institute for Responsible Technology, 2009).
  • Potential toxicity: Biotechnology crops have been linked to disease, sterility and death. Animal deaths were linked to Biotech cotton plants, corn and potatoes and people in five Filipino villages became ill when Biotech corn was pollinating (Institute for Responsible Technology, 2009).
  • Environmental concerns: The GM crops may themselves become weeds, they may move GM crops may serve as conduits and move to wild plants creating weeds, they could produce toxic substances which can spread to plants and animals, and they could affect the ecosystem. So far none of these concerns have come to fruition (Mellon & Rissler, 2003).
Here in the United States GMO’s are considered safe based on experience not on scientific testing. In order to know for sure whether they are safe or not, scientific research and testing must be conducted to find out how the new proteins which are formed affect human health and how the transfer of the new gene affects plant metabolism (GMO Compass, 2006).

So to answer the question posed in the title of this article, even though the benefits of GMO crops have the potential to increase crop yields, reduce food shortages and improve the nutritional value of the world’s food supply; not knowing whether or not these foods are safe for human consumption makes eating them a questionable practice.

The Health Benefits of Journaling

All my life, the leaders of my church (The Church of Jesus Christ of Latter-day Saints) have counseled us to keep a journal (LeAnn, 2011) . Their reason of doing this was to preserve your life history for your posterity. If you want to know more about the LDS (Mormon) perspective on journaling you can go to: http://mormonwoman.org/2011/06/06/the-purpose-of-a-journal/

Recently, while studying stress for my Exercise Fitness class in college, I was reminded of the other benefits of keeping a journal. Journaling in general is a great way to get your feeling out and an excellent mental health strategy. Sometimes writing things down helps you identify your problems and get your feelings out. We sometimes don't recognize that we are under stress until we get our feelings on paper. One great thing to do in a journal is look for the positive things in your life.

In an article I found entitled “The Health Benefits of Journaling”, the scientific benefits of journaling are discussed (Purcell, 2006).

These benefits include:

  • Clarifying your thoughts and feelings. Taking a few minutes to jot down your thoughts and emotions will quickly help you get in touch with them.
  • Help you get to know yourself better. Writing routinely will help you get to know what makes you feel the way you do and become more clear about situations and people who are toxic.
  • Reduce stress. Writing about anger, sadness and painful emotions helps you feel release some of the intensity of the emotions and feel calmer.
  • Solve problems more effectively. Writing unlocks your creatively, which engages your right-brain and gives you another prospective on them.
  • Resolve disagreements with others. Writing about misunderstandings helps clarify your feelings thus releasing some of the emotions so that you are better able to understand the other persons point of view (Purcell, 2006).

In addition to all the benefits previously mentioned, journaling helps you look back and see patterns, trends, improvement and growth over time. Reading your journal enables you to look back at past problems and see how you have resolved them (Purcell, 2006).
