Nanotechnology sounds like something out of a sci-fi movie—not something that should be on your plate. The same goes for genetic modification, but a new study shows a large number of American consumers are fine with adding them to the menu as long as it makes their food safer or more nutritious. In fact, they would even pay more for such foods.
The study was a collaborative effort between North Carolina State University and the University of Minnesota. Researchers surveyed more than 1,000 randomly selected consumers and asked them to participate in a survey about whether or not they would consider purchasing nanotech or genetically modified (GM) foods if it meant gaining certain benefits.
Participants were divided into four specific groups based on their responses: those concerned mainly with price (23%); those who preferred to avoid such modifications unless there were proven safety benefits (19%); those who would not buy nanotech or GM foods at all (18%); and those who would buy such foods if they were told they were safer or more nutritious. This last group, dubbed the “benefit-oriented” group, had the largest number of respondents at 40%.
In terms of food, nanotechnology means using nanoparticles (microscopic particles) in the production or manufacture of food to alter how it looks, tastes, and even how long it will stay fresh and edible. Genetic modification refers to changing the genetic makeup of a crop in a way that would not occur naturally. But how do we even know if these practices are being used? And are they really as beneficial as manufacturers claim?
In the United States, mandatory labeling of GM foods is not required, though many state and national initiatives have been proposed. Current law only requires food labeling when there is a substantial difference in the nutritional or safety characteristics of a new food.i (Interestingly enough, genetic engineering does NOT fall under that definition, according to the U.S. Food and Drug Administration.) Likewise, nanotech foods are not subject to any special regulation with regard to manufacture and labeling.
As consumers, we can make healthier choices by doing our research and paying attention to the products we buy and the companies we buy them from. Web sites such as the Non-GMO Project and The Project on Emerging Nanotechnologies Consumer Products Inventory can help shoppers determine which companies are making GM and/or nanotech foods.

As if trans fats aren’t bad enough as it is, now they could be making us forgetful? That’s what researchers from the University of California San Diego determined recently after completing a study that included nearly 700 men age 20 and older.
The more dietary trans fats they consumed each day, the more difficulty they had with memory—specifically, word memory. Those who ate the most trans fats (about 15 grams per day) recalled approximately 0.76 fewer words, which translated to about 11 or 12 fewer words out of a total of 86. That’s about a 10% drop in memory, researchers point out.
In addition, there was evidence to support an association between higher trans fat consumption and worse memory performance in young adults, said lead author Dr. Beatrice Golomb in a recent article. She added that this was an important point because those are often key “career-building” years.
As to why or how trans fats affect memory, researchers speculate the unhealthy fats may infiltrate healthy cells—including brain cells—and disrupt their function, but more research is planned to support this theory. Findings from the UCSD study were presented last month at the American Heart Association conference in Chicago.
