‘Misleading’ New Study Claims Eating Meat Helps You Live Longer

Should vegans be worried? Let's take a closer look at the newly published study...

“Sorry vegans! Australian study finds eating MEAT correlates to a longer life expectancy,” say the Daily Mail headlines. The research compared life expectancy with meat consumption among the populations of 175 countries based on data from the Food and Agricultural Organisation (FAO) of the United Nations.

Researchers found that countries with a greater meat intake also have greater life expectancy and decided the two were related. Interestingly, beer and wine come out relatively near the top among some of the high-meat consuming countries too!

The FAO’s most recent data lists the top five meat consumers as Hong Kong, the US, Australia, Argentina, and Spain. The bottom five were Ethiopia, India, Bangladesh, Democratic Republic of the Congo, and Burundi.

It’s not surprising to see a discrepancy in life expectancy between these two groups. But surely education, income, public health spending, and access to clean water, among many other factors, have a larger impact on life expectancy than meat intake?

Scientists say that Hong Kong’s leading longevity, for example, is “the result of fewer diseases of poverty while suppressing the diseases of affluence.” A combination of prosperity and low levels of smoking helps.

While researchers accounted for some differences (e.g., calories consumed, wealth, urbanization, obesity, and education), they acknowledged shortcomings in their study. They wrote: “Nutritional variations among countries include many more variables than those included into this study.”

They didn’t compare the quality of foods being eaten in different countries – a significant flaw!

Fact and fiction

Much of this study appears to reflect opinion rather than fact. The authors said: “A recent dietary advice published by Lancet Public Health advocates an increase of dietary meat in order to benefit our heart health and longevity.”

But it didn’t. The research advocated carbohydrates making up 50 percent of energy in “a balanced diet that includes fruit, vegetables, legumes, whole grains, nuts, fish, dairy, and unprocessed meats – all in moderation.” In fact, the EAT Lancet Commission says: “A diet rich in plant-based foods and with fewer animal source foods confers both improved health and environmental benefits.”

They question the link between saturated fat in red meat and the onset of atherosclerosis (furring up of the arteries) contravening all official guidance which warns against saturated fat. They also question the huge body of evidence linking meat with disease, saying, “there has been no clinical trial evidence to consolidate the putative negative effects of processed meat consumption for human health.” Are they questioning the World Health Organisation’s finding, along with a wealth of other evidence, that processed meat is a Group 1 carcinogen and causes cancer? This is wilfully misleading! 

The research showing how meat harms, they say, is not reflected in official healthy food guidelines. But it is; the UK government’s Eatwell Guide encourages people to consider alternative sources of protein to meat. It reads: “Pulses, such as beans, peas and lentils, are good alternatives to meat because they’re lower in fat and higher in fiber and protein, too.”

It advises eating less red and processed meat like bacon, ham, and sausages too.

A wealth of large-scale studies have pointed to the health benefits of plant-based eating.

An outdated understanding

The new study attempts to discredit “vegetarian research,” criticizing the methodology of a number of highly respected large-scale studies. The reputable Seventh-Day Adventist studies, for example, take many more variable and confounding factors into account than this study, as does the large EPIC-Oxford study that has reported many health benefits for plant-based diets. 

Lastly, the researchers say: “From the evolutionary point of view, meat has arguably been an indispensable component in human diet for millions of years, which is evidenced, genetically, by meat digesting enzymes and digestive tract anatomy.” This demonstrates a naïve and outdated understanding of human evolution and physiology.

Just consider our blunt soft fingernails, our short canine teeth, and amylase, for example, the enzyme produced in our pancreas and salivary glands that helps us digest carbohydrates.

We are much more suited to a plant-based diet than one containing meat. And evidence shows that our Palaeolithic ancestors ate a much more plant-based diet than previously thought. The average life expectancy of our ancient ancestors was just 25 years. So, even if they did live on a diet packed with meat (they didn’t) they simply didn’t live long enough to develop heart disease. Not a good starting point for modern dietary recommendations.

Earlier this month, research based on meta-analyses and data from the Global Burden of Disease study published in the journal PLOS Medicine, reported how dropping meat, dairy, and sugary foods and eating more pulses, whole grains, fruit, vegetables, and nuts could increase your life expectancy by more than a decade. Much better evidence-based advice!
