The Gut-Destroying Toxin You Eat Everyday


by: Dr. Craig A. Maxwell

Food 211

Since the 1990s, there’s been something different about the food you eat everyday. It still looks the same, it tastes the same but it’s not the same nourishing food your grandparents ate. Lurking deep inside a fresh-grilled ear of corn or your favorite soy-based vegetarian dish could be a gut-destroying toxin. It’s called Bt toxin and what you don’t know about it could seriously affect your health.

What is BT Toxin?

Bacillus thuringiensis (BT) is a gram-positive soil-dwelling bacterium that has been used as an insecticide since the 1920s. When farmers spray their crops with this bacterium or its insecticidal proteins or spores, insects eat it and they die when their intestines explode. When this pesticide is just sprayed on your food, you are able to wash it off. Indeed, the spraying of it on crops, even organic crops, allows it to be washed off. Sunshine also quickly degrades it. When used in this way it is considered effective against pests and harmless to humans, as it is not absorbed into the plant.

Now with the advent of genetically modified crops, it is difficult to avoid this dangerous toxin. This is because biotech giant Monsanto decided to profit from this pesticide by splicing the Bt gene with corn, soybeans, and cotton. Now these plants have Bt toxin genetically inserted in them. It cannot be washed off, and it does not degrade during the growth cycle.

Monsanto describes these new crops as “pest-resistant”, giving unsuspecting consumers the idea that pests somehow smell the Bt pesticides and avoid the crops containing them. No. Nothing could be further from the truth. When any insect takes a bite of a genetically modified Bt toxin crop, the toxin literally splits their guts open and they die. So, why would you want to eat it? Remember, when it was only sprayed on the plant, it was easily washed off or degraded by sunshine.

Terrifying Side Effects of BT Toxin

According to a UK report published in 2004, twelve German dairy cows died a slow and painful death after consuming GMO Bt Toxin corn. Syngenta (a biotech company linked to Monsanto) has been trying to cover up this fact for nearly a decade.

Here are just a few of the side effects of Bt Toxin:

Boy getting shoot

  • Allergic Reaction

Your immune system is designed to protect you against toxins and foreign invaders. Bt toxin is a foreign invader, which means the more you eat GMO foods, the worse you’ll feel. You may develop allergic symptoms such as sneezing, coughing, wheezing, watery eyes, asthma, and hives and be unable to figure out what’s causing them.

  • Developmental Disorders

Studies have proven that animals given feed from GMO crops experienced noticeable alterations in their mood and behavior. Hogs exposed to Bt toxin exhibited cannibalistic behavior while rats who ate it exhibited signs of anti-social behavior, withdrawing from others and aggressively climbing the cage walls.

This has led researchers to believe that Bt toxin and autistic symptoms are closely-related because they seem to interfere with functional digestive development. Children with ASD have a disproportionate amount of gastrointestinal disorders, reinforcing the belief that gut and brain health are very closely connected.

  • Autoimmune Disease

Less than a hundred years ago, autoimmune diseases were uncommon. Now we live in a society where conditions such as celiac disease, Crohn’s disease, lupus, rheumatoid arthritis, Hashimoto’s thyroiditis and multiple sclerosis are almost commonplace. It’s becoming more unusual now not to have some type of autoimmune dysfunction than it is to be sick! Sick has become the societal norm and pesticides have been cited as one of the primary causes.

Since 80% of your immune system is located in your gut, the last thing you want to do is eat gut-destroying Bt toxins. One of the most alarming facts about Bt toxin GMO foods is their staying power.

Even if you eat a primarily organic diet and “slip up” every once in the while by eating some corn chips laced with Bt toxin, the effects of the toxin can stay with you. Once inside your stomach, these Bt toxins take can over by destroying your natural gut flora and forcing your digestive system into continually producing more of the pesticide!iStock_000000970628XSmall

  • Severe Food Allergies

Once your immune system begins to go haywire, it will be unable to tell the difference between whole organic food and genetically modified food. Once your healthy gut flora has been destroyed and altered, a condition called leaky gut syndrome will result. In a person with leaky gut syndrome, the intestinal lining is more porous than it should be. This allows toxins, undigested food particles, and bacteria to run unchecked in your bloodstream, causing chronic inflammation and multiple food allergies.

  • Kidney Disease

Your kidneys are designed to flush toxins from your body. Continually eating genetically modified crops containing Bt toxins may eventually destroy your kidneys.

  • Infertility


There is a rising theory among health-conscious individuals that one of the main purposes for the development of GMO crops is population control. When Mike Adams of interviewed a biotech scientist known only as “Ed”, the man confirmed that Bt toxins do, in fact, contribute to infertility and that he thought this fact was “awesome!” He went on to say that he believed genetically modified crops were doing humanity a favor because the world is overcrowded.

  • Cancer

The Institute for Responsible Technology reports 65 serious health risks associated with GMO crops, including cancer development. For example, rats fed potatoes engineered to produce their own insecticide developed precancerous cellular growth in their digestive tract.

Foods Containing Bt Toxin:

    • Corn – Unless it’s organic, stay away from corn. Over half of the corn grown in the United States is genetically modified to contain Bt toxin.
    • Soy – Studies have shown that soy is not the health food you have been lead to believe. Up to 90% of soy grown in the United States is genetically modified to contain Bt toxin.
    • Sugar Beets – In 2012, GMO sugar beets got the green light as well so avoid these and purchase organic beets only.
    • Diary Products – The milk you pour in your coffee and onto your child’s cereal each day could contain dangerous Bt toxins, as livestock are often fed corn and soybeans which most often contain Bt toxin. Use organic milk instead. Better yet, use organic almond milk.
  • Squash – Most yellow and zucchini squash is genetically modified and contains Bt toxins.


  • Cotton – Cotton has been genetically modified to produce Bt toxins. It is pressed into cottonseed oil which is used in     vegetable oil and margarine.
  • Beef-When possible, choose only grass-fed, organic beef. Cattle are often fed Bt toxin-containing feed.
  • Potatoes-Approved in 1995 by the FDA as the first pesticide-producing crop in the United States.

How to Avoid BT Toxin

The best way to avoid Bt toxins in food is to eat organic whenever possible. When selecting produce, it’s really important to understand what the label numbers mean. A four-digit number beginning with a “4” means it’s been conventionally-grown. A five-digit number that begins with a “9” means it’s organic. A five-digit number beginning with an “8” means it’s genetically-modified and contains harmful Bt toxins.

Also, it is very important to read food labels. Produce isn’t the only thing you have to watch out for. Any food containing corn, soy products, vegetable oil or dairy could potentially contain dangerous Bt toxins. Look for non-GMO or GMO-free foods only.

If you didn’t really understand the dangers about Bt toxins before, you’re not alone. These major biotech corporations will do anything it takes to make sure this critical information doesn’t reach you. Remember, become a label-reader, purchase organic, and look for “non-GMO” food labels. Once you stop unintentionally eating poison, your health will improve by leaps and bounds you never thought possible!



  1. Dr. Maxwell,

    I would like to get your free email subscription. I have been having problems with my gut (diarrhea) for about 4 years, but Culturette probiotics help. I then got the chickenpox from the Shingles vacine. Since then, my skin has been sensitive. I do not have Celiac Disease, but I seem to breakout & itch severely from wheat.
    The condition has not cleared up completely & I broke out in red checks & neck from eating Cheetos (a corn product). Now I am cutting out corn products, but have not cut out all corn deviratives. I am at my wit’s end, & can’t seem to find any doctors in Tennessee that know anything about bt-toxins. I think that must be what my problem is.
    Do you know a doctor in Tennessee that knows about this & can see me? I am looking forward to reading your emails. Thanks!

  2. Hello,
    I was finally diagnosed with leaky gut, after allergies to dairy and gluten, and after only 2 weeks of drinking (organic) bone broth, and eating only organic fruit, vegetables and neat, my symptoms have almost disappeared!

    • Hello Joe,
      Very true. Thank you for your input.
      As mentioned in this article, BT sprays are washed off by rain or degraded by sunlight. If any remains, it is hopefully washed off at home.
      Not much of a chance of eating it.
      Dr. Maxwell

  3. Useful info. Fortunate me I found your web site unintentionally, and I am shocked why this coincidence did
    not happened in advance! I bookmarked it.
