There is a definite link between meat and diabetes and consuming large quantities of red and processed meats can cause diabetes 2:

As there are more calories and fat in red meat than plant food and to avoid diabetes people need to include vegetables, fruits, nuts and seeds and this includes having low amounts of animal, products.

Also, what type of meat that people eat matters as they need to stick to very lean meat such as the breasts of turkey or chicken. Then the best beef cuts to eat is sirloin, flank steak, then there’s tenderloin and chipped beef. People can also eat lean pork such as tenderloin, ham or Canadian bacon and other types of meats that are suitable are veal (except cutlets) then there’s wild game such as venison, rabbit, duck, and goose (skin off).

Then the types of meats to avoid are beef spare, ribs, products made of pork, products made from ground lamb, and processed meats such as:

Sausages, and frankfurters, then there’s salami, corned beef, and luncheon meat as well.
