Authored by Camille Su via The Epoch Times (emphasis ours),

Gene editing has long been primarily used for research, treatment, and disease prevention. Currently, this technology is increasingly being applied to modify agricultural products to create more “perfect” species. More and more genetically edited foods are appearing on the market, including high-nutrient tomatoes and zero-trans-fat soybean oil.

Some argue that gene-edited foods are safer than genetically modified (GM) foods (pdf). The U.S. Department of Agriculture (USDA) specified in 2018 that most genetically edited foods do not need to be regulated. However, are these foods, which will increasingly appear on the table, really risk-free?

Gene Modification 2.0: Gene-Edited Foods May Become More Available

In September 2021, the first gene-edited food—Sicilian Rouge tomatoes—made with CRISPR-Cas9 technology were officially on sale.

This gene-edited tomato contains high levels of gamma-aminobutyric acid (GABA), which helps lower blood pressure and aids relaxation.

Japanese researchers remove a gene from the genome of the common tomato. After the gene is removed, the activity of an enzyme in tomatoes increases, promoting the production of GABA. The GABA content in this tomato is four to five times higher than that of a regular tomato.

Warren H. J. Kuo, an emeritus professor of the Department of Agronomy at National Taiwan University, explains that both gene editing and transgenic organisms are genetic modification, also known as genetic engineering.

The earliest technique was genetic modification, that is, transgenic—in which a plant or animal is being inserted a gene from another species, such as a specific bacterial gene. The purpose of artificially modifying plants and animals is to improve their resistance against diseases and droughts, promote growth rates, increase yields, or improve nutrient content. However, the finished product will exhibit the foreign species’ genes.

Kuo says that transgenic modification is “genetic modification 1.0,” while gene editing is “genetic modification 2.0.” Gene editing is directly modifies the genes of the organism itself, so most of them do not exhibit foreign genes. However, the most common gene editing technique, CRISPR-Cas9, introduces foreign genes as the editing tool, and then removes the transplanted foreign genes.

While gene-edited tomatoes were on the market, Japan also approved two types of fish genetically edited with CRISPR—tiger pufferfish and red seabream. These fish are genetically edited to accelerate muscle growth. Among them, the gene-edited tiger pufferfish weighs nearly twice that of the ordinary species.

Back in 2019, the United States had used another earlier gene-editing technique to create soybean oil with zero trans fat and introduced it into the market.

Gene-edited foods which have also been approved for sale worldwide by now include soybeans, corn, mushrooms, canola, and rice.

The number of genetically edited foods on the market is likely to increase. Patent applications relating to CRISPR-edited commercial agricultural products have skyrocketed since the 2014/2015 period.

Gene-Edited Foods May Pose 2 Major Risks

Proponents of genetic modification believe this is a method to perfect agricultural produce and solve problems such as pests, droughts, and nutritional deficiencies. But the technology is still a double-edged sword.

“Genetic engineering indeed has its benefits in the short term, but it may bring long-term pitfalls,” said Joe Wang, molecular biologist. Wang is currently a columnist with The Epoch Times.

Hornless cattle were once the celebrity of the animal kingdom, appearing in news stories one after another.

Many breeds of dairy cattle have horns, but they are dehorned to prevent them from harming humans and other animals, and to save more feeding trough space. To solve the “problem” of horns, the gene editing company Recombinetics successfully produced hornless cattle with gene-editing techniques many years ago.

The company simply added a few letters of DNA to the genome of ordinary cattle and their offspring didn’t grow horns, either.

However, a few years later, an accident happened.

The FDA found that a modified genetic sequence of a bull contained a stretch of bacterial DNA including a gene conferring antibiotic resistance, which has been one of the global health crises in recent years. Scientists aren’t clear whether this gene in gene-edited cattle will pose a greater risk than expected or not, and the FDA has stressed that it’s hazard-free. However, John Heritage, a retired microbiologist from Leeds University, told MIT Technology Review that the antibiotic resistance gene could be absorbed by gut bacteria in cattle and could create unpredictable opportunities for its spread.

In fact, this is one of the currently perceived risks of genetically edited foods. Genetic Accidents, New Toxins?

The problem with unexpected accidents in the genetic modification process occurs in GM foods because transgenic techniques cannot control where the foreign gene is embedded in the chromosome.

Kuo used the example of a study that compared the protein of transgenic soybeans and non-transgenic soybeans. These transgenic soybeans were initially embedded with one foreign gene, and should have had only one protein that didn’t exist before. However, the comparison showed that there was a difference of about 40 proteins between the two: Half of the proteins were originally present, but disappeared after transgenic modification; the other half were not present but were added after the transgenic modification.

In contrast, emerging gene editing techniques allow for more precise modification of specific genes (pdf). It’s like a tailor modifying a section of a zipper by cutting off a specific segment and replacing it with a new one. However, there may be mistakes and unexpected changes in the process of cutting and repairing, and another similar section of the zipper may also be cut off.

Kuo says that this process may have unforeseen side effects; for example, if during this, new allergy-causing proteins or new toxins are produced.

“The genetic engineering procedure, and this includes gene editing, has the potential to damage DNA,” said molecular geneticist Dr. Michael Antoniou, head of the Gene Expression and Therapy Group at King’s College London, in an interview in April 2022. “If you alter gene function, you automatically alter the biochemistry of the plant … included within that altered biochemistry can be the production of novel toxins and allergens … that is my main concern.” More Herbicide Use?

Another major concern with GM foods is herbicide residue.

Most crops, whether genetically edited or genetically modified, have herbicide-resistant genes incorporated into them. This is done so that when herbicides are applied to crops for weed control, the crops themselves won’t be harmed.

When planting herbicide-resistant crops, farmers can use herbicides rather liberally. But, long term, the weeds the farmers are targeting become increasingly herbicide-resistant as well, resulting in a cycle of increased herbicide use and resistance.

Since the introduction of herbicide-resistant GM crops in 1996, herbicides have experienced a significant growth in application every year. The herbicides residue in the crops grown are increasing as well.

One of the most widely used herbicides is glyphosate under the trade name Roundup. The International Agency for Research on Cancer (IARC) classifies glyphosate as a Group 2A carcinogen that is probably carcinogenic to humans.

Massachusetts Institute of Technology (MIT) researcher Stephanie Seneff and scientific consultant Anthony Samsel said in their study that 80 percent of GM crops, especially corn, soybeans, canola, cotton, sugar beets, and alfalfa, are specifically introduced with glyphosate resistance genes.

In addition to carcinogenic concerns, glyphosate may have more harmful effects. They have collected and reviewed 286 studies and indicated that glyphosate inhibits the activity of an enzyme in the mitochondria of liver cells—cytochrome P450—which has the ability to detoxify and decompose foreign toxic substances. Moreover, glyphosate also has adverse effects on the gut microbiota.

These effects are not immediately apparent, but in the long run may contribute to inflammatory bowel disease, obesity, depression, attention deficit hyperactivity disorder (ADHD), autism, Alzheimer’s, Parkinson’s, amyotrophic lateral sclerosis (ALS), multiple sclerosis, cancer, infertility, and developmental abnormalities.

An animal study published in Environmental Health shows that long-term exposure to ultra-low doses of glyphosate still causes liver and kidney diseases in rats.

Yeah, I was recently reading the ingredients on my food as one does from time to time, and at the bottom I saw may contain biological engageed food products. And I'm like what..... And I read everything else.. like 50 percent is bio engineering food

Freaky as fuck.
