If you drip water on cells, nothing happens they keep powering away at around 100% survival. A decade later, researchers tested to see what effect liquid smoke had on overall cell viability. Unlike the bacteria, the mutation rate shot up as more and more liquid smoke was added.īut, there’s little evidence that “mutagenic activity in a particular human cell line is more closely related to human health risk than is mutagenic activity in bacteria.” In other words, just because liquid smoke causes DNA mutations in human cells in a petri dish doesn’t mean it does the same thing within the human body.ĭamaging DNA is just one of many ways chemicals can be toxic to cells. Even as more and more smoke flavoring was added, the DNA mutation rate remained about the same.īut “he fact that …is not mutagenic in bacteria has little predictive value for on human cells.” So, a group at MIT tested a hickory smoke flavoring they bought at the store against two types of human white blood cells. What about smoke ingestion? Decades ago, smoke flavorings were tested to see if they caused DNA mutations in bacteria, and the test was negative. We know smoke inhalation isn’t good for us.
