This video analyzes various research findings on foods that cause pancreatic cancer and delivers accurate information to viewers. It takes an in-depth look at how alcohol, liquid fructose, processed meat, and charred meat affect pancreatic cancer development, correcting widely held misconceptions along the way. Specific advice on healthy diets and cooking methods for preventing pancreatic cancer is also provided. The video is based on information from the Doctor Dingyo channel and reflects accurate data as of March 3, 2026; it emphasizes that self-treatment or medication must always be discussed with a physician first.

1. Research Methodology for Food and Cancer 🤔

Doctor Dingyo notes that while YouTube is full of videos about foods that cause pancreatic cancer, most consist of nothing more than mechanistic speculation or unsubstantiated claims. He sets out to provide information on foods conclusively shown by modern medicine to cause pancreatic cancer.

Because it is impossible to directly experiment on whether a food causes cancer, he explains that observational studies are used to reveal the association between cancer incidence and diet. He identifies the most accurate research method as the cohort study, which follows a healthy population over a long period and compares cancer incidence against dietary intake. He particularly emphasizes that because cancer has an incubation period of roughly ten years, cohort studies lasting more than ten years are the most accurate, and meta-analyses that synthesize such cohort studies represent the highest level of evidence. 🌟

According to an umbrella review (a study that re-analyzes multiple meta-analyses) published by the University of Milan in 2022, foods that help prevent pancreatic cancer include vegetables (high evidence), whole grains (slightly lower evidence), and nuts (slightly lower evidence); cruciferous vegetables were also found to have a protective effect. However, results for red meat were inconsistent across studies, and a 2012 meta-analysis in particular found a high likelihood that it promotes pancreatic cancer. Chicken, eggs, and fish came out as neutral. Fruits and vegetables showed a protective effect, though more recent research suggests the benefit may come from the overall healthy dietary pattern rather than from any individual food.

2. Carbohydrates, Added Sugar, and Alcohol 🍻

2.1. Alcohol 🥂

Alcohol is identified as a near-certain factor in causing pancreatic cancer. In 2025, the DCPP (an international multi-center consortium) analyzed the relationship between alcohol consumption and pancreatic cancer across 30 cohort studies from Asia, Australia, Europe, and North America involving 2.5 million people. The results showed that pancreatic cancer incidence rose significantly starting from two drinks per day.

"It came out that two drinks a day is where pancreatic cancer starts to be caused. So one drink a day is safe, in that sense."

However, this refers specifically to pancreatic cancer; risk increases from one to two drinks per day for women and from two to three drinks per day for men. He warns that heavy drinking — five or more drinks per day (roughly one bottle of soju) — is a clear risk factor that dramatically raises the risk of developing pancreatic cancer. 😱

"One bottle of soju every day: very high risk. Clear risk. There are actually quite a few people who drink a bottle of soju every day. Listen carefully. Pancreatic cancer will clearly develop, and the risk is very high."

Doctor Dingyo sincerely urges those who drink a bottle of soju daily to cut back to one drink or fewer per day, and stresses that, for preventing not only pancreatic cancer but also liver disease, dementia, and all other conditions, not drinking at all is the healthiest choice.

2.2. Carbohydrates 🍚

Some studies find that refined carbohydrates have no association with pancreatic cancer, though he explains that the number of studies is too small to draw a definitive conclusion. Whole grains, on the other hand, have been clearly shown to help prevent pancreatic cancer.

• Whole grains: Protective effect; supported by moderate-quality evidence.
• Refined carbohydrates (white rice, polished rice): Came out as neutral (no association), but confidence is low due to insufficient research.
• Donuts, processed cereals: May have some risk, but this is likely attributable to added sugar rather than refined grains themselves.

There has been no direct pancreatic cancer research on common Korean foods such as gimbap, sushi, white bread, noodles, or tteokbokki.

2.3. Fish 🐟

Fish overall shows a neutral relationship with pancreatic cancer.

• Cooked fish excluding raw fish and fried fish (grilled, steamed, in stews): May help prevent pancreatic cancer.
• Fried fish: Came out as neutral (protective effect disappears).
• Salt-cured fish (jeotgal, anchovies): May slightly increase the risk of pancreatic cancer.
• Raw freshwater fish: Can cause bile duct cancer due to parasites — he strongly advises never eating it. (Possible association with pancreatic cancer as well.)

2.4. Added Sugar (Fructose) 🍬

Fructose is identified as one of the most clearly established risk factors for pancreatic cancer. A 2022 systematic review from UT Southwestern Medical Center in Texas found that fructose consistently causes pancreatic cancer.

"Fructose, at least, looks almost certain. The one thing that consistently comes up as a cause is fructose."

Sugar (a disaccharide in which fructose and glucose are bonded together) is less dangerous than fructose alone, but fructose in its pure monosaccharide form directly promotes cancer cell growth. Specifically, pancreatic cancer cells have an abundance of fructose transporters (GLUT5), and fructose is metabolized without a brake, being channeled into fat synthesis that accelerates tumor growth. Fructose also causes fatty liver, which in turn leads to a fatty pancreas that raises the risk of pancreatic cancer.

"Fructose both causes and grows pancreatic cancer. So from the pancreas's perspective, fructose is clearly far worse than glucose."

Foods with the highest fructose content are cola and carbonated beverages, but fructose is also present in large amounts — in forms such as liquid fructose, other fructose derivatives, and crystalline fructose — in fruit juices, sports drinks, energy drinks, vitamin drinks, and tonics, which are often perceived as "healthy beverages". 😢 He points out that these drinks, which are commonly given as get-well gifts, can actually be harmful to pancreatic cancer patients, and calls for greater public awareness.

"People bring vitamin drinks to a pancreatic cancer patient, hoping they'll recover quickly, and they're gifting those vitamin drinks that contain fructose. Isn't that a bit chilling?"

He also cautions that instant (mix) coffee, RTD (Ready to Drink) canned or bottled coffee, and coffee shop syrups (mostly fructose-based syrups) contain large amounts of fructose and warrant attention.

2.5. Fruit and Avocado 🥑

Fruits, which contain natural fructose, are rich in antioxidants and contain only modest amounts of fructose — unlike cola — and therefore do not cause pancreatic cancer. The latest research suggests that rather than fruit itself, a healthy dietary pattern that includes a variety of fruits contributes to pancreatic cancer prevention, and fruit on its own likely has a neutral relationship with pancreatic cancer.

Avocado, which some videos name as a cause of pancreatic cancer, has no direct research linking it to the disease. In fact, a 2023 cohort study found that men who ate avocado once a week had a 15% reduction in overall cancer incidence. Although pancreatic cancer was not specifically included, combining findings such as a study showing that unsaturated fatty acid intake reduces pancreatic cancer incidence by 8%, he concludes that avocado is unlikely to cause pancreatic cancer and may even have a protective effect. 👍

3. Protein, Red Meat, and Fried Foods 🍗🍟

3.1. Protein 🥚

Protein — both animal and plant-based — shows a neutral relationship with pancreatic cancer. Chicken, fish, and eggs all appear to be unrelated to or neutral with respect to pancreatic cancer development.

3.2. Red Meat and Processed Meat 🥓

Red meat and processed meat are described as difficult to interpret because research results are conflicting. A 2012 meta-analysis found that processed meat increased pancreatic cancer incidence by 19%, and red meat consumption in men increased pancreatic cancer incidence by 29%.

However, the most recent 2023 study (analyzing only research published since 2016) found that both red meat and processed meat had a neutral relationship with pancreatic cancer. 😮 Doctor Dingyo attributes these conflicting results to the cancer incubation period (at least ten years) and reverse causation.

"Body weight starts dropping three years before a pancreatic cancer diagnosis. So, so to speak, even in the pre-stage of pancreatic cancer — the seeds of pancreatic cancer — appetite actually drops markedly."

In other words, in short-term studies, people who were already in the early stages of pancreatic cancer may have eaten less meat because of reduced appetite, while healthy people who ate a lot of meat may not yet have developed pancreatic cancer during the observation window, diluting the association. He emphasizes that long-term observational studies lasting 20 years or more consistently show red meat raising pancreatic cancer incidence by 18%.

He strongly recommends avoiding processed meat not only because of its link to pancreatic cancer but also because of nitrosamines — Class 1 carcinogens formed when nitrites and heme iron in the meat react with stomach acid — making processed meat harmful for preventing other cancers as well.

He explains that the primary reason red meat causes pancreatic cancer lies in the carcinogens generated when it is grilled:

• Heterocyclic Amines (HCA): Carcinogens formed from the chemical transformation of meat components under high heat.
• Polycyclic Aromatic Hydrocarbons (PAH): Benzo[a]pyrene is a key example; large amounts are released in charcoal grill smoke.

He notes that these carcinogens spike dramatically during charcoal grilling and are concentrated in charred portions. He refutes the claim made by some experts that "ingested benzo[a]pyrene is harmless," stressing that ingested benzo[a]pyrene is also a clear Class 1 carcinogen that causes various cancers including colorectal cancer, stomach cancer, and pancreatic cancer. The intestine does contain benzo[a]pyrene-degrading enzymes, but their concentration is too low to fully detoxify it. 😥

"Ingested benzo[a]pyrene — ingested polycyclic aromatic hydrocarbons — are unambiguously Class 1 carcinogens. There is mechanistic evidence, animal evidence, and human clinical evidence. They are clearly Class 1 carcinogens not only for colorectal cancer but for pancreatic cancer as well."

What makes charred meat even more dangerous is that its carcinogens act synergistically with fructose to promote cancer development. Carcinogens cause DNA damage while fructose activates the signaling pathway (mTORC1) that stimulates cancer cell growth. He therefore advises against drinking cola alongside meat.

Doctor Dingyo does not tell people to stop eating meat, but encourages healthy cooking methods:

• Low-temperature cooking — boiling or steaming: Enjoy meat in a wide variety of preparations such as bossam (boiled pork belly), shabu-shabu, steamed dumplings, stew meat, bulgogi, braised beef, or galbi-tang (short-rib soup). Carcinogen formation is reduced by more than a hundredfold with these methods.
• Eat with vegetables: The antioxidants in vegetables help mitigate the harmful effects of carcinogens.
• Remove charred portions: Carcinogens are concentrated in the burned parts; always cut them away.
• Prevent oil from dripping onto charcoal: When oil drips and smoke rises, far more carcinogens are produced.
• Choose water, tea, or zero-sugar drinks instead of alcohol or cola

He also reemphasizes that, since an incubation period of at least ten years has been confirmed for the relationship between smoking or occupational carcinogen exposure and pancreatic cancer, short-term study results on food and pancreatic cancer are also susceptible to the trap of reverse causation.

3.3. Fried Foods 🍟

A 2022 cohort study observing 100,000 Americans over 8.8 years produced the surprising result that fried food consumption was associated with a 36% reduction in pancreatic cancer. 😮 Chips in particular — potato chips, tortilla chips, corn chips — were found to reduce pancreatic cancer by 32%.

"Eating fried food came out as preventing pancreatic cancer by 36%. That's an enormous protective effect. People who don't accept reverse causation would have to start eating fried food."

However, Doctor Dingyo firmly explains that this result is also a product of reverse causation. Patients in the early stages of pancreatic cancer are likely to be the first to cut back on greasy snacks due to poor appetite or indigestion, while healthy people who ate a lot of fried food simply had not yet developed pancreatic cancer within the 8.8-year observation window. He therefore points out that concluding potato chips prevent pancreatic cancer is clearly a misinterpretation.

So is fried food safe? Acrylamide in fried potatoes is classified as a Group 2 carcinogen. Because acrylamide spends little time in the digestive tract, its association with gastrointestinal cancers such as stomach cancer, colorectal cancer, and pancreatic cancer is low — but because it is absorbed quickly and lingers in urine for a long time, it increases the risk of urinary tract cancers (kidney cancer, ureteral cancer, bladder cancer). It may raise the risk of bladder cancer up to sixfold.

"The acrylamide in french fries is absorbed quickly. Absorbed quickly means it spends little time in the digestive tract. So stomach cancer, liver cancer, colorectal cancer, pancreatic cancer — the association there is lower. But it lingers in urine. That means acrylamide exposure time is longer in the kidneys, ureters, and bladder — so there's the risk of kidney cancer doubling, bladder cancer increasing sixfold, and upper urinary tract epithelium increasing about 1.6-fold."

He therefore emphasizes that, even though fried potatoes may not directly affect pancreatic cancer, they carry risks for other cancers and should be consumed with caution.

4. Pancreatic Cancer Food Tier Summary 📊

Doctor Dingyo synthesizes the research findings reviewed so far and classifies foods into tiers based on their risk level for causing pancreatic cancer.

• Tier 1 (Almost Certainly Causes Cancer) 🥇:

  • Alcohol: Pancreatic cancer risk increases with two or more drinks per day. (This does not mean one drink is fine — abstaining entirely is best for preventing all diseases.)
  • Liquid fructose (cola, other fructose products, crystalline fructose, etc.): Fructose is the most clearly established factor that both causes and promotes the growth of pancreatic cancer.

    "Ultimately: bring on the alcohol and meat. If you eat meat grilled and charred over charcoal, and you always drink two or more drinks alongside it, you will get pancreatic cancer."

• Tier 2 (Probably Causes Cancer) 🥈:

  • Charred meat (grilled red meat, charcoal-grilled meat): Long-term studies of 20 years or more consistently show elevated pancreatic cancer risk. The main culprits are carcinogens such as benzo[a]pyrene and heterocyclic amines.
  • Processed meat (ham, sausage, bacon, Spam, etc.): The direct link to pancreatic cancer is ambiguous, but because these contain Class 1 carcinogens, consumption should be avoided.

• Tier 3 (Neutral) 🥉:

  • Fruit: Contains natural fructose, but is rich in antioxidants and contains only modest amounts — and does not appear to cause pancreatic cancer. (Preventive effect is also ambiguous.)
  • Avocado: Low likelihood of causing pancreatic cancer; may actually have a protective effect.
  • Refined carbohydrates (gimbap, tteokbokki on their own): Likely neutral with respect to pancreatic cancer on their own. However, excess consumption leading to obesity, a fatty pancreas, or diabetes will increase pancreatic cancer risk. Gimbap and tteokbokki themselves are not carcinogenic.
  • All proteins (chicken, fish, eggs, etc.): Mostly neutral.

• Tier 4 (Protective) 🏆:

  • Whole grains
  • Cruciferous vegetables (cabbage, etc.)
  • Allium vegetables (onions, garlic, etc.)
  • Nuts

  A healthy diet built around these foods helps prevent pancreatic cancer.

Finally, he presents a study finding that men who followed a "Western dietary pattern" — high in red meat, processed meat, potato chips, sugary drinks, snacks, high-fat dairy, eggs, and refined carbohydrates — had a 2.4-fold increase in pancreatic cancer incidence, underscoring that risk multiplies when several risk factors combine.

Conclusion 🎯

For preventing pancreatic cancer, the single most important step is to eliminate alcohol and fructose from your diet. In particular, hidden fructose in carbonated beverages and processed drinks must be avoided. Cook meat using low-temperature methods such as boiling or steaming, and when grilling over charcoal, remove charred portions and take care to prevent oil from dripping onto the coals. He reemphasizes that consistently eating a healthy diet centered on whole grains, vegetables, and nuts is essential for preventing pancreatic cancer and a wide range of other cancers. 💪
