That's because it doesn't increase the risk of type 2 diabetes. It's Jackanory. The whole idea is claptrap. A narrative pedalled by evolution-deniers who want the world to adopt the Garden of Eden diet.
The studies which say that meat consumption does increase the risk of Type 2 diabetes are based upon food surveys. Firstly they don't distinguish between prime cuts of meat and mechanically extracted meat in cheap meat pies. Secondly some of them only did a total of 3 surveys of their subjects with up to a 12 year gap.
Do you remember exactly what your weekly diet consisted of over the last 12 yrs? The vast majority of people will have no idea.
I have a pretty good idea because for over a decade I was eating high Carb Low Fat, Low meat (mainly veggie) then very recently after T2D I saw the light and switched around completely to Low Carb High Fat.
So a low meat (and particularly low red meat diet 'gave me T2D' - according to the standards of those studies.
But in this forum we can be pretty sure that it wasn't the low meat, it was what I ate instead of the meat - Carbs in large quantities including the infamous '5 a Day !
