The Dangers & Risk of GMOs & How To Avoid Them

Genetically modified foods are everywhere, and their safety is still debated. Learn how GMOs work, why they may be harmful, and how to avoid them in your diet.

Genetically Engineered Food – Is It Safe?

Let’s break it down:
GMO stands for Genetically Modified Organism, and while some claim it’s safe, the truth is—we don’t fully know yet.

In animal studies, rats fed a diet with just 11% GMO content developed large tumors by 13 months old. That’s like a person eating only 11% GMO food and developing tumors by age 43.

Today, about 95% of corn, soy, canola, cottonseed, and sugar beet crops grown in the U.S. are genetically modified. Unless a product is labeled “organic” or “non-GMO,” you should assume it contains GMOs.

 

Despite rising concerns, GMO labeling is not required in the U.S., and 27 countries have banned them entirely—not including the U.S..

How GMO Farming Works

Genetically modified seeds are designed to survive heavy doses of Roundup, a weed killer containing glyphosate. Here’s what happens:

  1. Farmers plant GMO crops.

  2. They spray the fields with Roundup to kill weeds.

  3. The GMO crops survive—but absorb the glyphosate, which stays in the food.

Why is that a problem?

  • Glyphosate is labeled a “probable carcinogen” by the World Health Organization

  • It can’t be washed off

  • It’s harming ecosystems, like the monarch butterfly population, by destroying milkweed

  • We still don’t know the full impact on long-term human health

How to Avoid GMOs

If you want to limit GMO exposure, follow these tips:

  1. Avoid these crops unless labeled organic/non-GMO: corn, soy, canola, cottonseed, sugar beet

  2. Buy organic—organic foods can’t be genetically modified

  3. Look for “Non-GMO Project Verified” labels

  4. Watch PLU codes:

    • Conventional bananas: 4011

    • Organic bananas: 94011

    • GMO bananas: 84011

  5. Shop at stores that reject GMOs—like Trader Joe’s

  6. Avoid farm-raised fish

  7. Limit eating out at places that don’t commit to non-GMO or organic ingredients

  8. Choose organic poultry and eggs

  9. Buy grass-fed beef (it’s not grain-fed and less likely to be exposed to GM feed)
