       | I think a meaningful question to ask is what other foods are also

       | products like seafood, poultry, cheese, or ready-to-eat cooked-
       | in-plastic meals.
       | 
       | We already have at least one study that points towards
       | ultraprocessed food consumption as increasing the risk of
       | specifically ovarian cancer by 30%. I wouldn't be surprised to
       | find colorectal cancer rates similarly increased with their
       | consumption.
       | 
       | It'd be interesting to see a metastudy on whether dietary-
       | associated cancers, endocrine disruption, and lower testosterone
       | are correlated with industrial single-plastic packaging for
       | majority-consumed foodstuffs.

         | My guess is, assuming to genetic predisposition, colorectal

         | micro biome, etc.

           | "What makes the increase particularly mysterious is the fact
           | that the overall incidence of colorectal cancer has dropped
           | by 45% since the mid-1980s. While the cancer is still most
           | frequently diagnosed in people over 55, the study found that
           | patients younger than 55 were 58% more likely to be diagnosed
           | with advanced disease."
           | 
           | If the cause were beef and milk consumption _as such_ , it
           | seems unlikely that a severe shift like this would occur. To
           | me, it's far more likely to be something like crop
           | dessication for grains--they started soaking cereal crops in
           | glyphosate prior to harvest and suddenly this category of
           | food that sustained the planet for millennia suddenly starts
           | causing broad spectrum inflammation that people blame on the
           | crop and not the processes and adjuncts.

           | I smell a Bayer, Nestle, DuPont, J&J, Pfizer, Monsanto, etc-
           | style hidden externality at work rather than animal
           | husbandry. Like, what are the colorectal cancer rates for
           | those people that actively practice transhumance? Do they
           | differ significantly despite predominantly animal-product and
           | dairy-based diets?

       | Does this square epidemiologically with beef consumption? The
       | countries with the highest beef consumption are in South America
       | (and it's _sharply_ more beef consumption); the countries with
       | the highest colon cancer rates are in central and northern
       | Europe.
       | 
       | It doesn't follow from a correlation that beef is by itself
       | causative; it can be, for instance, beef plus some other
       | X-factor. Somebody is going to point out that South American
       | cattle are grass fed, but European cattle are also more grass fed
       | than American cattle, and yet they still top the leaderboard.
