Surprising Reason Antibiotic-Laced Meat Could Be Making Us Fat and Sick

New research identifies a correlation between diversity of gut microflora and obesity, heart disease and cancer.

For decades, livestock producers have used low doses of antibiotics to expedite animal growth. The practice, dubbed sub-therapeutic antibiotic therapy (STAT), lowers feed costs while increasing meat production, and nearly 80 percent of the antibiotics used in the United States are for this purpose.

Because STAT can encourage the growth of antibiotic-resistant "superbugs,” it’s banned in many countries, but remains common in the U.S., despite recent public pleas to stop it by two former FDA commissioners. Although STAT has been in use since the 1950s, how it works has long been a mystery. But evidence is mounting that it might be due to antibiotics killing microorganisms that populate animals’ guts.

If so, antibiotics could do the same thing to humans. In support of this idea, a paper published last month in Nature identifies a correlation between diversity of gut microflora and human obesity. A nine-year study, led by S. Dusko Ehrlich of France’s National Institute for Agricultural Research, compared microbiotas—the 100-trillion-member microbial ecosystems that populate the body—of slim and obese people. The team found obese people have lower microbial diversity in their bellies. This is consistent with earlier research in mice, as well as a paper published last year in Journal of Obesity that found a strong correlation between young children’s exposure to antibiotics and later obesity.

Perhaps more significantly, the team behind the Nature study found a correlation between low microbial diversity and heart disease, diabetes and cancer, regardless of weight. "Even lean people who are poor in bacterial species have a higher risk of developing these pathologies," Ehrlich told NPR.

Our understanding of human microbiota is in its infancy, but the possible implications of such research are profound. Could our frequent use of antibiotics, both to treat human sickness and to encourage animal growth, be having unintended consequences on our health?

There are strict limits on the amount of antibiotic residues allowed in commercial meat, and according to the USDA’s Food Safety and Inspection Service, violations of these limits are extremely rare. But this could be interpreted in two ways: maybe there isn’t much antibiotic residue in meat, or maybe the legal thresholds are set too high.

Research published last year in the journal of the American Society for Microbiology found that legal amounts of antibiotic residues in cured meats can still be high enough to kill bacteria sausage manufacturers intentionally apply to their products. Sausage is treated with lactic acid-producing microbes to make it more acidic, which kills dangerous microbes like salmonella and E. coli. The researchers found that while legal levels of antibiotic residues in meat don’t kill the pathogenic microbes, they can kill the acidifying microbes intended to keep the “bad” bugs at bay.

The growing recognition of the importance of gut flora has spawned a probiotics industry valued at $8.7 billion, according to Carl Zimmer at National Geographic’s Phenomena blog. Currently, the retail products of that industry are regulated as food and cosmetics, not as medicine.

Zimmer notes: “It’s possible that the bottle of probiotics you buy in the drug store really will help your digestion, or your immune system, or your bad breath. But it’s also possible that the bacteria you’re buying will get annihilated in the ruthless jungle that is your body. A lot of species you’ll find in probiotic products do not actually belong to the dominant groups of species in the human microbiome. Stop eating them, and they’ll disappear from your body.”

That said, the Nature study did identify eight species of bacteria generally missing from underpopulated guts, and there is talk of putting those in a probiotic. But until such a product is available, there are other promising approaches to managing your microflora.
