A new study challenges the common practice of giving low-fat diets to people with acute pancreatitis (sudden inflammation of the pancreas). Researchers compared 65 patients who ate either a normal-fat diet (30% of calories from fat) or a low-fat diet (15% of calories from fat). Those on the normal-fat diet ate more calories in their first two days of eating and reported better quality of life, with no increase in complications. This suggests that the standard low-fat diet recommendation may not be necessary for most pancreatitis patients.

The Quick Take

  • What they studied: Whether people with acute pancreatitis (sudden pancreas inflammation) need to follow a low-fat diet or can safely eat a normal amount of fat
  • Who participated: 65 adults with mild to moderate acute pancreatitis who didn’t have high triglycerides, split into two groups eating different amounts of fat
  • Key finding: People eating normal amounts of fat consumed more calories in their first two days and had better quality of life, with no increase in complications compared to those on low-fat diets
  • What it means for you: If you have pancreatitis, you may not need to strictly avoid fat in your diet, but always follow your doctor’s specific recommendations for your situation

The Research Details

This was a randomized controlled trial, which is considered the gold standard for medical research. Researchers randomly assigned 65 patients with acute pancreatitis to eat either a normal-fat diet (getting 30% of their daily calories from fat) or a low-fat diet (getting only 15% of calories from fat). They carefully tracked what patients ate, measured their quality of life, and monitored for any complications over 90 days. The study took place from July 2022 to April 2023, giving researchers enough time to see both immediate and longer-term effects.

The random assignment helps ensure that any differences between groups were due to the diet itself, not other factors. By tracking patients for 90 days, researchers could see if the normal-fat diet caused any delayed problems that might not show up immediately.

This study used strong methods with random assignment and careful monitoring. However, the sample size of 65 patients is relatively small, and the study only lasted a few months. The results need to be confirmed in larger, longer studies before changing standard medical practice.

What the Results Show

The main finding was that people on normal-fat diets ate significantly more calories during their first two days of eating - about 18.7 calories per kilogram of body weight compared to 12 calories for those on low-fat diets on day one. This difference was especially pronounced in malnourished patients, who ate 23.2 calories per kilogram on normal-fat diets versus 15.6 on low-fat diets. Over the entire study period, the normal-fat group still ate more calories on average, though this difference wasn’t quite statistically significant. Most importantly, people on normal-fat diets reported much better quality of life, with higher scores in both physical well-being (53.9 vs 39.4) and mental well-being (55.9 vs 40.7).

There were no significant differences between the groups in terms of abdominal pain levels, increases in triglycerides (blood fats), infections, length of hospital stay, or readmissions within 90 days. This suggests that eating normal amounts of fat didn’t cause the complications that doctors typically worry about.

This study challenges current medical guidelines that recommend low-fat diets for pancreatitis patients. Previous recommendations were based on theory rather than direct comparisons like this study provides. The results suggest that the traditional approach may be unnecessarily restrictive.

The study was relatively small with only 65 patients and followed them for just 90 days. It only included patients with mild to moderate pancreatitis who didn’t have high triglycerides, so the results may not apply to all pancreatitis patients. Longer studies with more patients are needed to confirm these findings.

The Bottom Line

Based on this study, people with mild to moderate acute pancreatitis who don’t have high triglycerides may not need to strictly limit fat in their diet. A normal-fat diet appears safe and may help with getting enough calories and maintaining quality of life. However, this goes against current medical guidelines, so patients should discuss this with their healthcare providers.

This research is most relevant for people diagnosed with acute pancreatitis and their healthcare providers. It may not apply to people with severe pancreatitis, chronic pancreatitis, or those with high triglycerides. Anyone with pancreatitis should work with their medical team rather than changing their diet on their own.

The benefits of better calorie intake were seen within the first two days, while quality of life improvements were measured throughout the treatment period. However, more research is needed to understand long-term effects.

Want to Apply This Research?

  • Track daily calorie intake and fat percentage, aiming for adequate calories (your healthcare provider can help determine your target) while monitoring any digestive symptoms
  • If you have pancreatitis, work with your healthcare team to determine if you can include moderate amounts of healthy fats in your diet rather than strictly avoiding all fats
  • Monitor energy levels, digestive comfort, weight maintenance, and overall quality of life while following your prescribed diet plan

People with pancreatitis should always follow their healthcare provider’s dietary recommendations, as individual cases may vary significantly. Do not change your prescribed diet without consulting your medical team.
