The UPF Threat Grows (Again!)
There’s no shortage of reasons to cut ultra-processed foods (UPFs) from your plate.
We’ve already seen them linked to cancer, obesity, heart disease, metabolic dysfunction, dementia… the list goes on.
And now, if you needed yet another reason to stay far away from this modern-day Frankenstein fare…
A massive new systematic review has just connected UPFs to a significantly increased risk of Crohn’s disease—a painful and often debilitating form of inflammatory bowel disease (IBD).
The study, published in eClinicalMedicine, pooled data from 72 prospective studies and tracked more than 2 million participants. It’s one of the most comprehensive efforts to date exploring how food affects IBD risk.
And while the researchers didn’t find consistent links between diet and ulcerative colitis (another form of IBD), the evidence against UPFs and Crohn’s disease was unmistakable.
In fact, both inflammatory diets and high intake of ultra-processed foods significantly increased the odds of developing Crohn’s.
Meanwhile, healthier dietary patterns—like the Mediterranean diet, a high-fiber diet, and consuming minimally processed foods—appeared to offer meaningful protection.
And this wasn’t just a vague association.
The risk was dose-dependent, meaning the more UPFs someone ate, the higher their risk climbed.
Let’s pause for a second: If Big Food were held to the same standard as Big Tobacco, headlines like this would trigger national investigations. Instead, these products continue to dominate grocery shelves, marketed as “healthy,” “convenient,” and “harmless.”
Make no mistake—they are not.
Crohn’s disease isn’t just a tummy ache. It’s a lifelong autoimmune condition marked by abdominal pain, diarrhea, fatigue, weight loss, and inflammation that can ravage your digestive tract.
And once you have it, there’s no cure.
So why keep waiting for the next shoe to drop?
This research adds to a mountain of evidence suggesting that our food system—especially our over-reliance on UPFs—is making us sick, one bite at a time.
Friend, prevention begins with your plate.
Avoid ultra-processed foods like:
- Sugary breakfast cereals
- Packaged snacks (especially with long ingredient lists)
- Processed meats
- Soda and diet drinks
- Frozen ready meals
Instead, stock your kitchen with:
- Fresh vegetables and fruits
- Whole grains like oats and brown rice
- Wild-caught fish and grass-fed meats
- Olive oil and avocados
- Fermented foods like sauerkraut or kefir
And if you’re concerned about gut health—or have a family history of IBD—consider adding these natural supports:
- L-glutamine – This amino acid helps repair the gut lining and reduce intestinal inflammation.
- Probiotic supplements – A high-quality, multi-strain probiotic can restore healthy gut flora and boost immunity.
Of course, diet alone isn’t the only piece of the puzzle. Regular exercise, stress management, and quality sleep all play important roles in maintaining a healthy digestive system.
But let this be a wake-up call: If ultra-processed foods haven’t already earned a spot on your “Do Not Eat” list… they should now.
To a healthier gut (and a cleaner pantry),
