Avoiding GMO Food Might Be Tougher Than You Think

While there’s currently no evidence that genetically modified organisms harm human health, that isn’t to say there aren’t legitimate reasons to avoid them.

GM experts and proponents also have legitimate concerns that adding a label identifying GMOs gives the impression that there are scientifically proven risks to worry about. Studies on perception of GM food suggests that the public has a baseline aversion, and a label may increase wariness. Labeling advocates, of course, argue that if Americans want to avoid GMOs, they have a right to do so.

“Can people avoid them? The answer is certainly yes. Especially in the last few years there have been more products on the market that are non-GMO or organic,” says Jayson Lusk, an economist at Purdue University who studies the consumer side of GMOs. “Now, those products are more expensive—no one ever said you can avoid them for free. But they can if they’re willing and able to pay, and one way they’ll pay is in the time to find the products.”

Highly processed ingredients like high fructose corn syrup have little to no traceable DNA in them, and so the U.S. Department of Agriculture (which regulates food labels) doesn’t require manufacturers to add a label to indicate those bio engineered foods.

In contrast, the USDA regulations allow companies to choose between three options: write out the warning (as in “contains a bioengineered food ingredient”), include a BE label, or use a QR code that would link the consumer to a page disclosing all the information.

Which Crops Are Genetically Modified?

While we may not yet know exactly how genetically modified foods affect our health, many of us have taken the preemptive steps to avoid them in our diet.

The good news is that, despite all the press on GMOs, there aren’t a lot of crops that are actually genetically modified. The bad news is that, for people who eat a lot of processed food, those few crops are in a huge percentage of food products (as opposed to whole food).

Unfortunately, the U.S. government elected not to legally obligate manufacturers to label our foods when they have GMOs in them.

Well, when others won’t take responsibility for what they are doing, when the authorities drop the ball, the onus falls on us to avoid becoming the victims of their misdeeds. We know what foods to avoid:

Corn
Soy
Sugar
Canola and Cotton
Papayas

Better Diet Data Via Tooth-Mounted Sensors

In First World countries, where famine is unheard of, people are instead eating themselves to death.

Oftentimes, diet studies rely on self-reported surveys and journals that are hostage to the whims of each participant. People forget. People feel self-conscious about their food choices and may fudge (pun intended) the data. However, a new sensor that fits on a person’s tooth could cut out this unpredictable variable—human nature— altogether.

Researchers from Tufts University School of Engineering designed a tiny sensor that, when stuck to a tooth, can wirelessly relay precise information about glucose, alcohol and salt intake. When the device comes in contact with salt, for example, its electrical properties shift, causing its other components to absorb and transmit different radiofrequency wavelengths unique to each chemical or nutrient. That information is then beamed to a mobile device for recording.

“In theory we can modify the bioresponsive layer in these sensors to target other chemicals – we are really limited only by our creativity,” says Fiorenzo Omenetto, an author on the study, which was published recently in the journal Advanced Materials. If you can put it in your mouth, it appears Omenetto and his team can measure it.

Debate Over GM Foods Continues

According to Dick, there thousands acres of land being farmed within 25 miles of Fort Morgan. The need for food in Colorado is rising higher as the population grows, but the understanding of what that takes to produce enough food for all, according to Dick, is shockingly low.

“A lot of people don’t realize what it takes to get the food on their plate. They just think it comes from the grocery store,” said Dick.

“The bottom line is that there is no particular reason to believe that currently available GMO crops pose any health risk, or that they are different with regard to their safety and nutrition from their conventional analogues. There is also nothing about the current processes used to generate GMOs that would theoretically pose a unique health risk,” state a report by the National Academy of Sciences (NAS).

According to studies, it takes about one acre to feed a person for a year. The study also states that the average American consumes about 2,000 pounds of food annually. Dick explained that crops are not only used as a direct food product to consumers, but also to feed livestock for meat production and even, in the case of corn, used to produce ethanol gas.

Reports by the USDA, the average corn harvest is about 147 bushels per acre, or about 8,250 lbs. The vast majority of corn, according to the report, is roughly split between ethanol factories and animal feed, with perhaps 10 percent or less used for food directly.

According to Dick, a lot of science beyond GMOs is also implemented when planting and growing crops. Growing crops, he said, can be a complicated and delicate process. Even when crops have been planted under perfect conditions, severe weather can destroy them or prohibit them from harvesting.

Are GMOs bad? Science Says They’re Safe

Genetically modified organisms (GMOs) are hotly debated all around the world. Many people are very concerned about engineering crops and animals because of the long-term effect this might have on our planet and our bodies. It’s no wonder then that the opinions people have about GMOs are so polarizing.

According to a 2016 survey conducted by the Pew Research Center, “about half of Americans (48%) say the health effects of GM foods are no different than other foods, 39% say GM foods are worse for one’s health and one-in-ten (10%) say such foods are better for one’s health.” About one in six Americans are deeply concerned with GMOs and predominantly believe GM foods pose health risks.

Are GMOs safe?

Despite the public having polarized opinions on the safety of GMOs, scientists overwhelmingly agree that GMOs pose no hazard to consumers. In sharp contrast to public views about GMOs, 89% of scientists from the American Association for the Advancement of Science (AAAS) believe genetically modified foods are safe, the Pew Research Center study found.

“There are several current efforts to require labeling of foods containing products derived from genetically modified crop plants, commonly known as GM crops or GMOs. These efforts are not driven by evidence that GM foods are actually dangerous. Indeed, the science is quite clear: crop improvement by the modern molecular techniques of biotechnology is safe. Rather, these initiatives are driven by a variety of factors, ranging from the persistent perception that such foods are somehow “unnatural” and potentially dangerous to the desire to gain a competitive advantage by legislating attachment of a label meant to alarm. Another misconception used as a rationale for labeling is that GM crops are untested,” reads an AAAS statement.

Genetically Modified Organisms Can Help With Food Security

Abu Dhabi: Despite the controversy surrounding it, genetically modified organisms (GMOs) used for food can play a big role in meeting the world’s future food security needs, with scientific studies thus far showing that genetically modified foods pose no harm to humans, said a distinguished researcher in Abu Dhabi on Wednesday.

Held at New York University Abu Dhabi, the talk was given by Nina Fedoroff, a molecular biologist who has served as science adviser under former US secretaries of state, Condoleezza Rice and Hillary Clinton. During her talk, Fedoroff acknowledged that a public mistrust towards GMO foods existed, but pointed out that the use of GMOs was growing around the world.

“GM crops were grown by roughly 18 million farmers in 26 countries on 457 million acres [of land in 2016],” she added, highlighting an official study that was carried out by the International Service for the Acquisition of Agri-biotech Applications.

“More than 90 percent of the farmers growing [GM foods] are resource-poor farmers in developing countries, [and] the overall profits were roughly equally divided between the developed and the developing world. So it’s not a simple case that this only benefits big farmers,” she said, highlighting how farmers were also benefiting.

Why We Cannot Gamble On Genetically Modified Foods

It is nevertheless also important to recall the many instances where for-profit scientific breakthroughs have brought humanity dangerous products marketed by those with financial interests in them as silver bullets to our many problems.

Think asbestos, think DDT, think plastics and hundreds of other products. Think also of such disasters as Bhopal, Chernobyl, Fukushima and similar catastrophes whose damaging effects will last for thousands of years.

And nothing can be scarier than handing our food security to the ones whose abiding interest is to maximize their own profits, without any concern for the externalities they generate in pursuit of that narrow self-interest.

In falsely claiming no adverse health effects from GMOs (when they have done everything in their considerable power to prevent long-term studies of such effects), the GMO industry and their well-funded army of lobbyists already show they cannot be trusted. Thus the need to fully apply the precautionary principle to the introduction of their products and to put the onus on them to prove both the benefits and benign health effects of this highly-chemically impregnated ‘foods’.

Food is too critical to the survival of all living things and our environment to transfer to the control of those whose sole interest is narrow profit-maximization. Let us not commit mass suicide.

Do You Happily Eat Genetically Modified Foods?

Talk about genetically modified (GM) foods causes angst for some people who’re concerned about eating healthily because they worry that too little is known about the long-term effects of modified foods to label them safe.

But others say that controlling our food’s characteristics is nothing new, having been practiced in agriculture for hundreds of years. For example, being selective about the fruit and vegetables we propagate means that we now have products that are larger, are more resistant to natural elements and taste better.

The Australian and New Zealand Food Standards Website explains that “today’s techniques use new ways of identifying particular characteristics and transferring them between living organisms”. For example, the site explains that it’s now possible to make a copy of a particular gene from the cells of a plant, animal or microbe, and insert the copy into the cells of another organism to give it the same characteristic.

What are the health concerns?

Some of the health concerns that have been brought up since the inception of GM foods range from the possibility of new diseases being spread among crops or transmitted to humans, to an increase in allergic reactions.

In 1996, a study found when desired genes from a brazil nut were transferred to a soybean, the allergenic properties were too. While this prompted a ban on using gene modification on allergenic there have been cases of genetically modified foods escaping into the wild.

A Diet High In Fat Is Best – With The Right Kind Of Fat

This is the time of year we tend to consider a change in diet. There has been a lot of confusion in recent years about what constitutes a healthy diet, with many people advocating and espousing a ketogenic diet, similar to the Atkins diet: a low-carbohydrate, high-fat/high-cholesterol diet (HF/HC). Since most North Americans will die of a heart attack or stroke if they don’t die young from another cause, this is a big mistake.

In 2016, there were large headlines trumpeting that “we can eat cholesterol now; the new U.S. guideline says so.” But that’s not what the guideline said. It said that there were insufficient data on which to base a specific limit to daily cholesterol intake, as in the past, but the intake of cholesterol should be as low as possible within the recommended eating pattern.

A study that clarifies what is the best diet for weight loss and diabetes was done among overweight residents of a nuclear facility in Israel, who were randomized to a low-fat versus a low-carb HF/HC (Atkins) diet, versus the Mediterranean diet. Weight loss was identical on the Mediterranean diet and the low-carb HF/HC diet, and both were better than the low-fat diet. The key finding, though, was that the Mediterranean diet was clearly the best for lowering blood sugar, fasting insulin levels and something called insulin resistance (a pre-diabetic state).

So the healthiest diet is the Mediterranean diet – a high-fat/low-glycemic index diet. This is why recent guidelines – the 2016 U.S. guideline, and the Canadian guideline now in development – are moving toward a more plant-based pattern of eating. We should limit red meat, avoid egg yolks and have three vegetarian days a week.
