I would just like to say--no guilt trip intended.
Further more, if you choose to stick with red meat, I would concur with Pops on "eat grassfed," whether that's beef or venison or buffalo.
Otherwise...lot's of good tips there. Besides high fructose corn syrup, pretty much anything made with white flour is gonna be pretty much like a sugar IV straight into the veins. IIRC, white French bread was about the highest on the glycemic index.
Along those lines and getting back to the thread topic: You can eat 100% vegan and stay pretty darn low on the glycemic index by eating unprocessed whole (here meaning especially still in the grain--wheat berries, oat groats, rices...not flour or cracked or rolled...) grains and following Pop's advise and a few other pointers.
(BTW, you are always free to take any thread of mine anywhere you like, Pops--it always ends up somewhere pretty interesting. Glad to hear that you have adjusted, as it sounds, pretty well to your new regime.)

More on the cancer thing: "...there is convincing evidence that
high consumption of red meat (beef, pork, and lamb) and processed meat (hot dogs, bacon, and deli meats)
does increase colon cancer risk. (52)
It’s best to
limit red meat consumption to no more than twice a week, and to avoid processed meats."

)
(And I would say that "avoid processed meats" should kinda go without saying!)
From further along in the same study, in the section on obesity:
$this->bbcode_second_pass_quote('', 'P')eople who ate more
nuts, a high-fat food that was traditionally taboo for dieters,
gained less weight over the course of the study—about a half pound less every four years.
People who ate more
vegetables, whole grains, and fruits also gained less weight.
In contrast,
people who ate more red and processed meat over the course of the study gained more weight—about a pound extra every four years.
