Red meat may not cause harmful inflammation after all

HOUSTON — A little inflammation is usually a positive sign the immune system is at work, but chronic inflammation can take a heavy toll on the body’s cells, tissues, and organs. Doctors have long advised patients to avoid eating too much red meat as a means of avoiding chronic inflammation, but have burgers and steaks gotten a bad rap? Researchers from Baylor College of Medicine say red meat may not be so bad after all.

“The role of diet, including red meat, on inflammation and disease risk has not been adequately studied, which can lead to public health recommendations that are not based on strong evidence,” says Dr. Alexis Wood, associate professor of pediatrics – nutrition at the USDA/ARS Children’s Nutrition Research Center at Baylor College of Medicine and Texas Children’s Hospital, in a university release. “Our team sought to take a closer look by using metabolite data in the blood, which can provide a more direct link between diet and health.”

To study this topic, the research team analyzed cross-sectional data encompassing roughly 4,000 older adults participating in the Multi-Ethnic Study of Atherosclerosis (MESA). For reference, cross-sectional data is quite useful as a source of evidence on how diet affects health, as it makes use of data observed with free-living people, without any attempts to influence their usual lifestyle.

In this way, study authors believe it may be easier to take results from such earlier studies and apply them to non-research settings. Meanwhile, besides just assessing participants’ self-reported food intake and several biomarkers, the research team also gauged a large array of dietary intake metabolites in their blood. Plasma metabolites are useful in terms of assessing the effects of dietary intake as food is processed, digested, and ultimately absorbed into the body.

 

After adjusting for body mass index (BMI), researchers concluded the ingestion of unprocessed and processed red meat (beef, pork, or lamb) was not directly associated with any markers of inflammation. Researchers theorize this suggests body weight, not red meat, may be the real driving force behind increased systemic inflammation. Importantly, no link was seen connecting red meat intake and C-reactive protein (CRP), considered the major inflammatory risk marker of chronic disease.

“Our analysis adds to the growing body of evidence that indicates the importance of measuring plasma markers, such as metabolites, to track diet and disease risk associations, versus relying on self-reported dietary intake alone,” Dr. Wood explains. “Our analysis does not support previous observational research associations linking red meat intake and inflammation.”

Since observational studies, by their very nature, cannot establish cause and effect, researchers recommend that randomized controlled trials (RCTs) be conducted in the future to confirm these findings. Such trials should entail participants being randomly assigned to either consume a dietary factor of interest or not eat it. Several earlier RCTs have already demonstrated that lean unprocessed beef can be enjoyed as part of certain heart-healthy dietary patterns.

“We have reached a stage where more studies are needed before we can make recommendations to limit red meat consumption for reducing inflammation if we want to base dietary recommendations on the most up-to-date evidence,” Dr. Wood concludes. “Red meat is popular, accessible and palatable – and its place in our diet has deep cultural roots. Given this, recommendations about reducing consumption should be supported by strong scientific evidence, which doesn’t yet exist.”

I like the phrase they use “free-living “. As opposed to what, slaves to Big Food and Big Pharma?

I believe that article is a step in the right direction and that we, as a carnivore / keto community are starting to make an impact.

I’ve also noticed that in the scientific community that egos and monetary fundings are very strong influencers.
They have a very hard time admitting to their mistakes and many refuse to look at the truth in fear of losing funding, their jobs or being ostracized.

I have been seeing a trend where some scientists are slowly acknowledging in bits an pieces that they were wrong. They can’t just come straight out and say it but they bring it out as if it’s a new finding. If one tries to come out with the whole truth they are vilified, ostracized and run out on a rail tarred and feathered.

It’s all driven of course by those who have the most money to lose if the truth is exposed.

It’s refreshing to see someone having the guts to present a finding that’s honest but wait and see if someone doesn’t storm their castle with fire and pitch forks.
