A study found that processed meat consumption is inversely correlated with telomere length. That is likely due to the various chemicals and preservatives used in processing the meat, because unprocessed red meat did not have the same effect. https://www.ncbi.nlm.nih.gov/m/pubmed/27558579/ https://www.ncbi.nlm.nih.gov/m/pubmed/27558579/ If you’re curious about diet’s effect on longevity other than causing obesity and diabetes, I suggest reading “The Telomere Effect.” It’s a great book which also covers things like the epigenetic effects of stress and how stressing a pregnant woman could even cause epigenetic changes in the baby. Note that some of the research is new and not rigorously validated yet.
