The problem is that what you describe is an argument from silence. Firstly there are usually not available demographic records in ancient times surviving till now and secondly even for Boston in the 19th century, the diagnoses of causes of death in an age without autopsies for every death nor the complete medical kmloweldge to give dependable findings. Thirdly how many would have died before cancer would have struck them down in a time when they’re was lower life expectancy? In 1700, the average age when men died in Virginia was at the age of 48! https://blogs.ancestry.com/cm/six-unbelievable-but-true-facts-about-colonial-life/
On the rate of death on going all meat diet or carnivore, there may be insufficient data on this as there are no substantial human populations that I am aware of who are purely meat eating except for the inuit ans the latter was by necessity not choice due to their environment. The evidence of every civilisation producing positive health outcomes and longevity having a predominantly plant based diet with comparatively less meat to supplement it does tend to militate against the advisability of such a lifestyle choice. Furthermore it is a rich man’s lifestyle choice as going all meat in diet is considerablymore expensive than eating plant based food predominantly…
But even so, there are studies that seem to show negative results for those choosing a predominantly meat based protein source as opposed to plant protein…https://pubmed.ncbi.nlm.nih.gov/27479196/
Suggesting that the rate of meat consumption has gone down while the rate of death has gone up would at best only point to something else contributing to the mortality rate more than meat - it doesn’t give meat a pass since exposure of meat would be dropping. In other words that is a logical fallacy to make that argument.
However are u sure there has really been a drop in meat consumption globally? According to this website there has actually been a very substantial RISE in global meat consumption since 1961 in accordance with rising prosperity all over the world…

If so then if there is rising mortality rate then meat consumption is part of the problem?
