Are GMOs Safe?

Genetically modified foods (GMOs) have been popular in the news lately ever since California failed to pass Prop 37, which would have required the labeling of GMO ingredients on all products sold within the state. While California may be setting the stage for the discussion of future labeling of GMO foods in our country, currently there is no regulation anywhere in the United States requiring the disclosure of GMO ingredients to consumers. This is in contrast to countries such as those in Europe and South America, who highly regulate the cultivation and sale of genetically modified crops and often require the labeling of foods that contain GMO ingredients (1, 2). In America, unless you buy certified non-GMO food, there is no way to know if your food contains GMOs or not.

So why does it matter if our food contains GMOs? You may have heard from various media sources that genetically modified foods are perfectly safe and there is no evidence to suggest any long term risk from their consumption. On the contrary, there has been some evidence suggesting potential health risks caused by these foods; even scientists within the FDA itself have repeatedly warned that GM foods can create unpredictable, hard-to-detect side effects, including allergies, toxins, new diseases, and nutritional problems. (3, 4) With so much conflicting information, it’s hard to tell fact from fiction. Are GMOs safe for human consumption, or not?

What is Genetic Modification?

Genetic modification involves the transfer of genes from one species of plant or animal to another, using techniques that can cause mutations in the genome that may have unintended consequences for the crop’s safety. (5) The imprecise rearrangement of genes can create new proteins in these plants that may trigger allergies or promote disease. (6) Our immune systems often do not recognize these new proteins and may mount an immune attack against them if they enter our bloodstream intact.

These unintended gene transfers, along with those that are intended, can lead to significant changes in gut and immune function, and may have long-term consequences that are not yet known to the scientific and medical communities.

In genetically modified corn and cotton, a gene from a bacteria called Bt (Bacillus thuringiensis) is inserted, which causes a pesticidal toxin to be produced in every cell of the plant. This Bt-toxin kills insects that eat the plant by breaking down its gut lining and killing the insect from septicemia caused by the ensuing blood infection. (7) While this toxin has not been proven to be toxic in this way for humans and other mammals, several recent studies have suggested this toxin could have effects on immune health, gut health, liver and kidney function, and fertility.

The potential dangers of GMOs

The gut is most susceptible to the potential dangers of GMO consumption. Bt toxin produced by GMO corn has been shown to significantly alter immune function in mice, and may cause disrupted immune function in the gut. (8, 9, 10) One study suggested that Bt toxin has toxic effects on human cells in vitro, causing them to die prematurely. (11) This could cause damage to gut endothelial cells if the toxicity is found to occur in vivo. The potential intestinal effects of GMO consumption go beyond Bt toxin. Some argue that gut bacteria are capable of acquiring DNA sequences from GM plants, which could lead to the development of antibiotic resistance in those microbes. (12) It’s not yet fully understood what proportion of the GM genes are able to be transferred to gut microbiota.

There have been effects of GM corn found on organs outside of the intestinal system as well. Analysis of Monsanto’s own research and independent research by a lab in France determined that mice and rats eating Bt-toxin producing corn sustained liver and kidney damage. (13, 14) Other harmful effects were also noticed in the heart, adrenal glands, spleen and hematopoietic system of these GM corn-fed rats. Bt toxin has also been demonstrated to reduce fertility in mice, with fewer offspring being produced than by mice fed on natural crops. (15) While these are small, preliminary studies, it’s worth investigating the effects GMOs can have on other organs besides the intestines.

Since the research is in its infancy, GMOs may have associated health risks that we do not fully understand. The organization known as The Institute for Responsible Technology has developed a list of potential hazards of GMO consumption, providing a list of references for each health risk discussed. They have amassed a great deal of support for their position that GMOs are dangerous, and much of their information comes from research studies, clinical experience from doctors, and anecdotal evidence from farmers and parents of children who thrived on a GMO-free diet. (Unfortunately, the website’s statements exaggerate the findings of several studies, so it’s best to be a critical thinker and take the information with a grain of salt.)

Why is there still controversy?

Recent reviews have proposed a different story when it comes to GMO safety, arguing that the bulk of the evidence demonstrates no health risks associated with GMO consumption. (16, 17, 18) These reviews found GMOs to be generally safe with no multigenerational effects, but also recommended that more research continue to be performed on the health effects of GMO consumption in mammals. It’s interesting to note, however, that the majority of the studies considered by these reviews had been conducted by biotechnology companies responsible for commercializing these GM plants; this conflict of interest could have an effect on the reporting of certain data. That said, there’s no denying the fact that independent critical reviews have so far found GMOs to be safe in food.

Unfortunately, credible research demonstrating the potential dangers of GMOs is not only sparse, it is also inconsistent. While many scientists argue that GMOs are unsafe for human consumption, there are many more scientists who suggest that the evidence to date has not found any significant health risks from ingesting GMOs.

It’s impossible to tell at this point who has the right answer, and it’s unnerving that there is so much controversy over the safety of a food product that is present in 60 to 70 percent of processed foods found in grocery stores. (19)

A verdict on GMOs?

There hasn’t been nearly enough research performed on GMOs to make an informed decision on their safety. However, lack of proof is not proof against. While the available evidence is still mixed, it seems likely that genetically modified foods could have an effect on the immune response as well as the permeability of the gut. Whether or not this leads to an increase in disease is yet to be determined. However, if regular consumption of GMOs is able to cause leaky gut, it could play a role in the recent dramatic rise in obesity, diabetes, allergies, autoimmune disease, and infertility in our country.

I’m no conspiracy theorist, but I think there is enough inconsistency in the available evidence to support the removal of GMOs from your diet. Fortunately, purchasing certified non-GMO or organic foods and eating a whole-foods or Paleo diet will allow you to steer clear of most GMO foods on the market. Until more legitimate research is conducted, I believe it’s better to be safe than sorry and avoid genetically modified foods as much as possible.

  1. Something that I think wasn’t mentioned sufficiently in the article was that GMOs are typically only found in foods that would be bad for you anyway, even if they weren’t GMO. They’re common ingredients in processed foods, often as industrial oils which would be bad whether GMO or not. If you eat real whole foods from nature you’re automatically avoiding most GMOs except for the few foods that might be found in the produce section that could be GMO (such as papayas or some squashes). Basically if you avoid the bizarre concoctions made by food companies with a paragraph of questionable ingredients, and buy and make real foods (which is what Paleo is all about), you’re already avoiding almost all sources of GMOs.

    • look at the ingrediants in your food almost everything is Monsantos GMO, just about everything you eat is made from Corn with is ALL GMO

    • Jonathan/Joe,

      Agreed. But according to this “real science” site (nutritionasiknowit)

      seems to does a good job at bringing science and debunking all the issues surrounded around GMO’s.

      Doesn’t seem as “bad” as some of the wild claims made about, especially gluten, and even artificial sweeteners.

  2. Do you even know what GMO is or what it stands for? First off, Gmo stands for genetically modified. Yeah, modified. That doesn’t mean it was made in a test-tube or with agrobacterium. what everything thinks a GMO, is not what a GMO really is. Most GMOs are naturally occurring, or through cross pollination and propagation. what people should be calling it is a GEO. a Genetically engineered organism. But, what I don’t get is that people don’t like Gmos, but they will be fine with a baby that have had certain genes inserted in it. People are very ignorant when it comes to the subject. they don’t know how things are being tested and how accurate the tests are. everything you find at grocery stores is a GEO. If we didn’t have them we would be dead. Gmos give us food, shelter, clothes, etc. just because you don’t want a naturally occurring insecticide,fungicide, or herbicide that won’t even hurt you because your biological functions work different than bug, and mice. Science is about questioning everything you hear. not accepting it. most of the pesticides geneticists use aren’t going to hurt people in the slightest. with the improved nutrients, they have more beneficial properties than “organics” Even organic pesticides can kill people…Well im done ranting. god bless America

    • How do you know mixing pesticides with food doesnt hurt you in some fashion? You dont, so stop raving about something you dont know. If if can kill a lower life form, it can probably hurt you too.

      The real argument here is that, GMOs should be labeled just like any food additive or ingredient. I want to know what is in my food. I want the choice and not leave it to some corporation CEO to make my decisions for me. As we all know, corporations make decisions on profits and bonuses and not on what is the moral thing to do. History has proven that reality many times over.

    • People are fine with a baby having genes inserted? really?
      People are ok if we insert, say, shark DNA into a baby? how about something with a lower gestation period? Something that becomes self-sufficient sooner? etc… Please tell me where you have heard anyone advocating or even just accepting inserting non-human DNA into babies…

      With selective breeding you can breed for desirable traits *that are already there and accounted for in their DNA*, so please tell me how you would selectively breed wheat to contain fish DNA, for example? Do not confuse selecting for traits that are already there(or even crossbreeding) with directly modifying the genome.

    • You seem to really believe in GMO’s or GEO’s or whatever label you wish to use. That and, according to you pesticides don’t hurt us. Lastly, EVERYTHING IS A GMO OR GEO, according to you.

      First there is a substantial difference between grafting sauvignon blanc onto cabernet sauvignon and say inserting the genes of one fish into another or inserting the genes of an animal into a plant, or vice a versa.

      As far as pesticides not hurting us, why don’t you drink a cup of roundup, after all, according to you it won’t do a damn thing.

      The real question, do you work for Monsanto or some other biotech company? You must. Remember the company that’s telling everyone that GMO’s are safe is the same company that told everyone agent orange is safe, PCB’s are safe, and DDT is safe. We all know how that turned out.

    • Thank you so much for your input. I have been thinking the very same thing. I am 61 years old and I eat the worst of anyone on this planet. I have no health issues other than some joint problems and being over weight somewhat. I feel fine. I have no sugar, cholesterol, high blood pressure, or anything. I eat GMO’s all the time and have for the last 20 years. I believe that the brain has a placebo effect. If you “believe” that GMO’s will harm you , they will. Again, thank you for clarifying.

  3. After researching Monsanto, I decided to drop corn, soy, sugar, aspartame etc. I soon learned I needed to make my own food as packaged foods were not in line with my new resolve.
    Perhaps it was cutting out all soda pop, wheat and clear gmo’s, however I have more energy, better gut, more regularity.
    My TSH definitely improved as did my pre diabetes which was always diet controlled. One doctor was amazed at my blood sugar numbers. I think it was a combination of awareness of foods and a better immune system.
    I honestly believe the problem is complex as the practice of farming is ruining soils worldwide where gmo crops grow super weeds meaning more heavy duty pesticides with no crop rotations.
    Big business, production of animals without care, parents with small children affected by heavy topical pesticide (argentina – soy farms), farmers who cannot afford gmo seeds and bankrupted (india)….. the list is long!

  4. I hate to be crass here, but I’ll have to say it.

    If it smells like shit, do I really need to wait for the results of a study to tell me it is, indeed, shit?

    Thanks to the makers of “good ole common sense.”

    • I agree. Thing is, we don’t have a way of knowing whether our food is gm or not (unless you buy everything organic which, if it’s winter-spring and you live in Canada anyway, REALLY limits you- mouldy raspberries for 6$/250g! Yep. That’s what you get.). That’s why it’s important to inform yourself- not just to see if a study ends up proving that gmos are unsafe, but to find out which gmo products are on the market (products vary by country and new ones are entering the market daily).

  5. I study at McGill’s Agricultural Campus in Nutrition. McGill is SO PROGMOs. I went to a GMO debate once at McGill that had 3 speakers, all either working for biotech or a supporter of biotech/gmo. Conflict of interest much?
    Anyways, what’s interesting is that GMOs are generally considered safe and wonderful by everyone in either the food science (i.e. the people that study how to process, transport, make food), genetics, and agri departments but not really liked by those in the Nutrition department (i.e. my department). Go figure… what’s sad is that Monsanto and Syngenta (Monsanto’s sister organization) both sponsor McGill big time and guess who conducts the research?

    One thing to note though is that GMOs have been on the market for over 30 yrs. Papaya, alfalfa, squash (in US) sunflower (recently added), green peppers (in China), soy, corn, potatoes and cotton in the market are mainly GMOs. Other things, like seedless grapes, are not GMOs and were produced by conventional breeding. ALSO, IF YOU ARE DIABETIC AND TAKE INSULIN YOU ARE INJECTING YOURSELF WITH GMOs. Not necessarily a bad thing in the sense that it’s either you use insulin produced by a genetically modified bacteria or the insulin squeezed out of the pancreas of a dog or a pig. I’d personally prefer the GMO’d insulin vs killing a poor animal so I could live (though I’m not diabetic- thank god!).

  6. This is the only thing people need to pay attention to. Why are companies like Monsanto trying to take away our right to know what food has GMOs in it?? Once you think about that, the answer is clear. Go GMO free. I enjoy being healthy and alive. Common sense people, it’s the same shit the tobacco companies pulled decades ago.. Time will tell this sad story.

  7. I really appreciate this conversation. An actual STUDY on GMO’s… http://www.collective-evolution.com/2014/07/15/new-study-links-gmos-to-cancer-liverkidney-damage-severe-hormonal-disruption/
    I’ve learned more about GMO’s after watching “GMO OMG” and it has really opened my eyes. As for those who have gone all organic and are finding recovery, I’m so glad for you!! I hope to find this for myself as well, but reading your testimonies really inspires me concerning the organic aspect in relating – nonscientifically to what you are personally finding. It “seems” like there’s a rise of autoimmune conditions — again – a nonscientific statement — I really hope that the studies will be done — the studies and surveys (scientific) to show if yes or no that autoimmune conditions are on the rise or not, studies of people on non-gmo food after a year with certain food conditions and how it relates to their diets and health (they’d need to be on a regimented whole foods-like diet in order to find true results… Guys we need studies — too much is going on and advancing here to ignore this… There are real possibilities… Perhaps some people have discovered a scientific truth that is yet to be scientifically proven — Science needs to get busy with no bias and do some fact finding — this is our country– this is our food supply — this is our future — the future of our population… Hoping someone will post links of scientific studies that need funding…

    • trouble is…1. it is my fundamental right to know what I am purchasing. 2. we should be able to control where crops are planted to keep organic free of cross pollination 3. we don’t need studies funded by companies who influence outcomes; our universities are infiltrated with special interests. 4. We have based our change in recommended diet on some of the worst science ever (reference Taubes). 5. Federal govt. With bill hr1599 passed in house july 23 will deny all of us these rights.

  8. People in the United States and Canada are fortunate since even though organic meat is more costly than conventional meat, it is still affordable. Also, since the minimum wage in the US and Canada are US$7.25 and US$9.24 respectively, you could afford plenty of organic meat even if you work as a custodian for 8 to 10 hours.

    In Singapore, organic meat can only be purchased with the salary of a lawyer or physician. Since there is no minimum wage in Singapore, those who are stuck with blue-collar jobs will not have enough even to afford a paleolithic diet made up of conventional meat.

    500g (~1.10 lbs.) of organic beef mince in Singapore is SG$15.00 (US$12.00).

    Life is difficult.

  9. If by chance, GMO is taking off the market. Repercussions in the economics will fall and unemployment will rise. To include costs of medicine, food, clothing and increase of polyester/synthetic clothing formed by processing crude oil. Small farms will decrease while government farms and large companies will benefit the profit. Small farms will be under and be in line at the unemployment. By taking GMO out. It will have side effects

    • Some people need an education about pros and cons before going against something they do not fully understand. I can only recommend that USDA, FDA and sub governments to take company reviews under consideration when they conduct there on studies. Example. if a GMO company sends me a study of their crop(s) and I work for lets say USDA. I review it and do my study within USDA guidelines. Before making any decisions.

      • That is not true at all. Dont even attempt to justify the necessity of GMOs for production. The world did fine without GMOs and recent data states that organically grown products can be as productive as GMO tainted products.

        Besides that, the health consequences of GMOs far out weight any small additional gain in production (if any at all). Pesticides cause CANCER, and herbicides cause neurological diseases like Parkinson’s, MS, ALS, etc. Is your health worth gambling on the promise of corporate propaganda? At least, label these GMO products so I or anyone can make a conscious choice.

        • Golden rice will help alleviate deficiency problems. That is very close to a necessity. Besides that being a necessity is not morally or legally required to be in the market. t\The cosmetics industry, pro sports and jewelry industries are not necessary. Finally there are no more health risks with G.E. crops than any other method of production.

          • As of 2015, Golden Rice had not passed productivity standards in field trials. Or more simply, Golden Rice does not produce enough output in comparison to conventional rice to justify planting it.

        • Bob that’s true, organic crops CAN be grown rather than GMOs (and I am VERY much against GMOs) but it will take many many seasons to even get the land able to grow anything once you take a GMO crop out of it, first because those genetics are in the soil (the seed you can’t weed out) and because the soil (topsoil) has been so stripped it is not mineral rich enough to support truly organic farming.
          I do understand the commenter when he says prices would skyrocket and unemployment would rise dramatically. That has been shown to be true because absolutely everything is made by or supported by Monsanto and Monsanto likes BIG profits. Manufacturing WOULD be affected.
          Still, I feel like GMOs should be left to manufacturing and OUT of our food chain!

          • One way to change it is with your pocketbook. Buy organic. And, I think consider, if it does cost a little more, your health will be better and your healthcare will cost less. That’s what I’ve experienced anyway.

        • do realize our food has been genetically modified for millenniums! Selective and cross breeding is also genetically modifying a food. Thats why for example bananas are now seedless, (In the past they bore large seeds).

          • We are not talking about GMOs to make a fruit sweeter or seedless, we are talking about making a plant a pesticide generator to kill insects that pose a cancer risk for humans.

    • You didn’t say whether the small farms were organic or not. I would think small organic farms will increase. And, there are larger organic farms already…like Earthbound. Not sure how they would decrease. Can you explain. I think it would be a good thing that all foods contain less toxic substances for everyone’s sake. That’s the main goal.

      • Your comment raises the whole other debate as to whether organic growing practices result in food that is healthier than conventionally grown foods. Chemical use on conventional farms is highly regulated and proscribed, and due to the certifications and record keeping involved, not to mention the cost of the chemicals, these chemicals are not used indiscriminately. Many organic additives, on the other hand, are NOT monitored or regulated and can be as toxic or ‘hot’ as conventional ones.

        It amuses me that even in the original article here it is acknowledged that so far there have been no actual dangers identified that are traceable to the GMOs, yet since ‘unfortunately’ science has so far not supported his position, the author continues to advocate against them.

        • I know personally the benefits of organic food, since going organic. That’s actually why I say anything. Sorry, I don’t buy the ridiculous accusation that organic is just as bad if not worse? then regular…please 🙂

          • It costs about twice as much to farm organic as it does with gmo crops. We have an average sized farm and recently started growing corn. Without the Bt trait in the corn, the only way to combat insects is with pesticides, which are toxic to humans who must apply them. So minus gmo crops, you either deal with increased pesticide use (increased cost, toxic chemicals), or share your ears of corn with insects, lowering quality as well as quantity of the corn. Lower quality and quantity produced leads to higher prices for consumers. Just thought I’d give a farmers point of view on this as many are not familiar with it. Also, much of the corn that is produced with gmo crops is used for animal feed as well as ethanol production. It is most usually not consumed directly by humans. Maybe these affects would not be passed onto humans? I don’t know. One thing is certain, more studies are necessary without a doubt.

            • I’ve heard Bt corn has a lot less potential for aflatoxin contamination too (due to prevention of insect damage), which means less carcinogens in food. Do you know anything about that?

            • Well, I rarely have corn now because it’s not available in organic, however, I know it is grown organically and have had it. Guess I’m just going without. A lot of processed foods are made from it where the buyer is not aware, and I do believe either way people should know what they’re getting in food as well. I’m not out to put regular farming “out of business”, just to consider there are safer ways. Increased cost…actually, my healthcare costs less not needing a doctor so often, so, it kind of balances out for me.

              • Just to add, more people are willing to pay a little more so don’t let that stop you from growing organic. The market has grown very nicely.

          • I totally agree with you. I found a huge improvement in health eating organic NON GMO. GMO’s are ALL about the money. Monsanto has a history of greasing the wheels at the FDA and fudging test results to look favorable. No way gmo better than natural!

      • GM plants are more economical (All safety issues aside) and produce bigger harvests that are not susceptible to drought, herborival insects, and common plant viruses, which would provide lower prices than a small, or large traditional organic farm.

        • Safety issues asside? hmmm well, more economical or not, if your health suffers from lack of real nutrients, and pesticides now within the foods you eat, (where I suspect things like IBS, “leaky gut” and other digestive disorders come from) I believe you pay in the long-run (or short) physically and medically.

          • See the U. of Perugia safety study, or the genera list. There are many g.e. safety studies. The EFSA has paid for many.

      • Crops grown from GM seeds are cheaper, have a better rate of return (a larger crop), and are resistant to drought, certain herbavorial insects, and common diseases. This larger profit margin could possibly make traditional organic farming unprofitable to small, or large, organic farmers.

        • Jane, organic farming need not be traditional. There is a need for thr recycling of organic waste produced by urban areas and livestock farming.

    • This seems out of context. The study suggests that people with inflammatory disease have higher levels of DNA fragments, but not that the DNA fragments cause the disease. It actually better suggests that the inflammatory bowel diseases allow for more uptake of larger DNA fragments, yet again a lot more work is needed to prove any of it.

    • And the intake of organic foods correlates with the apparent increase in autism. Correlation does not indicate causation.

  10. Hello all. Sherry that’s a great testimony against GMOs. Actually, I started going organic because it was home delivered in my area and convenient at the time. Just by chance I noticed a few things. My hands no longer get dry, itchy and actually bleed in the winter. (5 years now) My appetite craving changed…it was kind of strange at first, no longer having to think of food all day. I lost some weight and kept it off..though I still have more to lose. I’m not on any calorie, low-fat, low-carb diet and don’t want to be :p…my son’s allergies dissipated…no longer sneezing and congested all day..year round actually for him. He hardly has headaches anymore also. That’s just a few things that we noticed. Thank you for a very good article Chris Kresser.

  11. most of this “gmo is bad for you” is a kinda wrong. i have looked up these articles. you have to think scientific on this. you can’t just assume something. the experiment with the rats was not being tested properly. one, there weren’t enough rats to do that. two, gt is a naturally occurring chemical found in soils. its been tested many times and used in organic farms. all it does is kill insects from eating the plant. and its effects on humans cant be proven that thoroughly. everyone is different in there genetic make up. some just have that happen to them.

    • Dear Pasha, please read my comment right above yours. I want to try to make what I said above clearer. In April of 2013, I discovered that I had an autoimmune disease called Hashimoto’s disease because my thyroglobulin antibodies were 567. I began a diet completely free of GMOs. A few months later my integrative MD told me I had increased intestinal permeability and I began to take an additional supplement, L-Glutamine. Seven months after finding out I had Hashimoto’s disease, in November of 2013, my thyroglobulin antibodies were 32.8. In brief … 567 in April … 7 months later … 32.8 in November. Although I thank God for healing me, there was nothing miraculous about the cure. I studied hours and hours and this excellent result is due to a logical application of what I learned. You mention that there is no proof of the negative effect of GMOs on the human body. I have been sick for 30 years and I could literally write a book on the negative effect of GMOs on the human body (as well as the negative effect of dental mercury, which began the assault on my body). Now I’m getting better and plan to go back to work for the first time in 30 years! Make no mistake. The discussion here is not “Are GMOs safe?” but rather “GMOs are not safe,” and I often weep when I see people sick and dying because they will not listen to warnings like these.

      • That’s interesting since GMOs werent largescale agriculture until the mid 90s… Less than 30 yrs ago. Good job with the anecdotal evidence and ‘science’ you did!

        • But, mercury and pesticide farming has been around longer hasn’t it. Her problems just began. Actually, as did mine with asthma. Digestive problems mostly in the late 90’s for myself. People don’t make things up about their health for the health of it 🙂

  12. On a GMO-free diet and after starting treatment for increased intestinal permeability (“leaky gut”), my Hashimoto’s Disease lab work improved dramatically.

    I have had many amazing recoveries but I have multiple health issues, and still have a number of challenges. I wish I could afford further testing because I believe my 66 years of life and well documented medical history takes up where Seralini left off.

    • Your treatment is responsible for your recovery. Treatment has measurable effects which can be demonstrated by repeated experiments. Your diet change is an unaccounted for variable which may or may not have had an impact on your treatment, and without repeated measurable results from other experiments any scientist would not be able to substantiate your claim. Your claim as it stands is purely anecdotal. What we need is an independent third party study on GMO’s so that we may then have a better picture of how they affect our lives and the environment. Until we have an unbiased report, the bulk of ANY GMO argument is here-say.

  13. I try hard to stay away from unnatural and processed foods. I cook with mostly organic and home grown foods. I did buy some corn tortillas from the store that were not organic. My two daughters and I had stomach aches for the rest of the evening. I know it was the tortillas, because everything else we ate was organic and not different from our diet. I believe it was the tortillas made with GMO corn.

    • Funny Donna, I am also totally organic. I did have a turkey deli sandwich on whole grain bread when out one day, thinking “ok, one time”, but the next morning…bp (I am guessing, not sure) but something was wrong…light headed…could hardly walk straight…that was the last time, have not felt that since. GMO or non-organic…not sure either. But, I play it safe staying organic.

  14. I don’t know if they are safe or not but I’m not going to stress out over it. The WHO seems to think they are safe.

    p.s. That’s the World Health Organization, not the rock band.

    • Yeah…well look into runs that (W.H.O.) ..they want a massive depopulation of the planet. Best thing anyone can do for their health is do their own research, don’t depend on corporations organizations that are money driven to dictate what is or is not safe. WHO, CDC…these are corporations in the end…its all about the money or where they get the money from. We live in a very greedy age..
