Wednesday’s Ask Dr. Walt — The Down Low on GMOs

Dear Dr. Walt,

Are GMO foods safe? Some claim it causes health problems. Others say it doesn’t. What the truth? Is there any clear evidence from reliable research?

—Seeking Safe Nutrition in New Jersey

Dear Foodie,

As the prevalence of genetically modified organisms (GMOs) continues to rise, there has been an increasing controversy concerning the safety of these products. It seems to me that these concerns focus on how the GMO may affect the environment or how it may affect the consumer. In particular, consumers seem worried about the possibility GMOs may negatively affect human health. This could result from differences in nutritional content, allergic response, or a wide-range of unrecognized and undesired side effects.

I’m no expert here, but a review in Harvard University’s Science in the News is reassuring to me. The authors point out that there have been over 100 research studies comparing the effects of traditional food to genetically modified food and the results of have been reviewed in various journals. Though knowing who to trust and what to believe regarding this topic is an ongoing battle, major health groups, including the American Medical Association and World Health Organization, have concluded from the research of independent groups worldwide that genetically modified foods are safe for consumers.

Harvard concludes, “After more than 20 years of monitoring by countries and researchers around the world, many of the suspicions surrounding the effects of GMOs on organ health, our offspring, and our DNA have been addressed and tested. … GMOs have been found to exhibit no toxicity, in one generation or across many. Though each new product will require careful analysis and assessment of safety, it appears that GMOs as a class are no more likely to be harmful than traditionally bred and grown food sources.”

    A few years ago I was listening to a radio program about GMO’s and heard that when genetically modified food (I think they referred to peanuts and corn but can’t remember for sure) the number of people coming down with severe allergic reactions showed a huge increase. When checking out safety of a new product like a GMO the safest thing would be to introduce one food group and watch it closely over a significant period of time and record health-related reactions and only then determine if it is safe. The way GMO’s are being put on the market now is irresponsible and putting people especially young children at risk of serious health issues.

    Look at next week’s column about GMO’s. You may feel better about them.
