SciTechDaily, Surprising Study Finds Meat May Protect Against Cancer Risk

A large study found that animal protein is not linked to higher mortality and may even help lower cancer-related deaths.

Eating foods that contain animal protein is not connected to a higher chance of death and may even provide some protection against cancer-related mortality, according to new research.

The findings, published in Applied Physiology, Nutrition, and Metabolism, are based on an analysis of data from nearly 16,000 adults aged 19 and older who participated in the National Health and Nutrition Examination Survey (NHAMES III). 

Researchers looked at how much animal and plant protein participants consumed and compared those patterns with their risk of dying from cancer, heart disease, or any cause. The results revealed no elevated risk of death linked to greater animal protein intake. Instead, the data pointed to a small but meaningful decrease in cancer-related deaths among people who consumed more animal protein.

“There’s a lot of confusion around protein – how much to eat, what kind and what it means for long-term health. This study adds clarity, which is important for anyone trying to make informed, evidence-based decisions about what they eat,” explains Stuart Phillips, Professor and Chair of the Department of Kinesiology at McMaster University, who supervised the research. 

To ensure reliable results, the team employed advanced statistical methods, including the National Cancer Institute (NCI) method and multivariate Markov Chain Monte Carlo (MCMC) modelling, to estimate long-term dietary intake and minimize measurement error.

“It was imperative that our analysis used the most rigorous, gold standard methods to assess usual intake and mortality risk. These methods allowed us to account for fluctuations in daily protein intake and provide a more accurate picture of long-term eating habits,” says Phillips.

 

The researchers found no associations between total protein, animal protein, or plant protein and risk of death from any cause, cardiovascular disease, or cancer. When both plant and animal protein were included in the analysis, the results remained consistent, suggesting that plant protein has a minimal impact on cancer mortality, while animal protein may offer a small protective effect.
