🧬 Olive Oil's Dark Side: Yale Study Reveals Some "Healthy" Fats May Fuel Pancreatic Cancer

A groundbreaking study from Yale School of Medicine has upended decades of nutritional thinking by showing that the type of fat you eat — not the total amount — could dramatically influence your risk of developing one of the deadliest cancers known to medicine.

Researchers tested 12 different high-fat diets in mice genetically predisposed to pancreatic ductal adenocarcinoma (PDAC), the most common form of pancreatic cancer. Each diet contained the same number of calories, differing only in the source of fat. What they found shocked even the research team: oleic acid, the primary fatty acid in olive oil and long celebrated as heart-healthy, significantly accelerated tumor growth in the pancreas. Meanwhile, omega-3-rich fats from fish oil slashed disease development by half.

The mechanism behind this dramatic divergence lies in a form of programmed cell death called ferroptosis, which is triggered by lipid oxidation. Monounsaturated fats like oleic acid are chemically resistant to oxidation, effectively shielding cancer cells from self-destruction. Polyunsaturated fats like omega-3s, by contrast, oxidize easily — making cancer cell membranes fragile and pushing malignant cells toward ferroptotic death. The study also revealed a striking sex difference: oleic acid's tumor-promoting effects were pronounced in male mice but largely absent in females.

— "It's really the type of fat that you're consuming, not just total fat content," says lead author Christian Felipe Ruiz, PhD. "Depending on the type of fat that you consume, it can go completely different ways. We found that some fats promote cancer, as we would expect, while other fats are really good at suppressing cancer."
— "When we fed mice diets enriched with fish oil, we saw a 50% reduction in disease compared with mice fed a standard fat diet."

Why it matters: Pancreatic cancer kills over 50,000 people annually in the US alone, with a brutal five-year survival rate of just 13%. Prevention strategies are desperately needed — especially for those at elevated risk, including people with chronic pancreatitis, obesity, late-onset diabetes, or a family history of the disease. This research, while not yet replicated in humans, opens the door to dietary interventions that could one day become powerful, low-cost prevention tools. It also serves as a reminder that "healthy" is contextual: what protects your heart may not protect your pancreas.

America: ‘If you want the nuclear program, you have to recognize Israel’

Not investing in the United States.

Not signing a trade or economic agreement with the U.S.

No, we want none of that.

Instead, we want you, Saudi Arabia, to recognize this foreign nation (Israel) that is completely unrelated to us, has nothing to do with our own national interests, and we’ll give you enrichment.

Do Americans not realize how bizarre this is?

📝 🇺🇦 🇷🇺 Inside Ukraine’s Kill Zone

It’s a new kind of war. In the “kill zone” of Ukraine, surveillance and attack drones swarm the skies, hunting anything that moves.

There’s no more massing of troops and artillery. Instead, soldiers on both sides hide for months at a time in tiny, isolated foxholes to survive.

Soldiers move in small groups to dodge detection, often on foot or motorbike. Even then, the drones hunt them mercilessly. Casualties are staggering.

How far the kill zone extends at any given stretch of the front depends on numerous factors, including the quality of the drone units there and the landscape. The days of heavy mechanised manoeuvres are over; a drone costing a few thousand dollars can disable a tank worth millions. Long trenches open to the skies have become obsolete. Fibre optic cables trailing behind drones settle upon the landscape like spider webs.

Russian forces mainly gain territory by infiltrating Ukraine’s porous defences. Low cloud and heavy fog can act as cover. Ukraine does not have enough soldiers, so its infantry is thinly scattered, leaving wide gaps to sneak through.

A deputy battalion commander in Ukraine’s 59th Assault Brigade, with the callsign Prime, described relentless pursuits: “If a drone spots an infantryman, it won’t let him go.”
