The FDA can only do what the laws allow and if the govt is controlled by lobbyist, well.... But this isn't the place for politics so I'll leave it at that.
I am very sorry about your horse. 😞
With meat.. it's particularly red meat that research is linking to cancer... early research shows amount is a big factor (recommendations from 4 oz a day to max 18 oz a week), but who knows. Processed meat is the worse, and I saw some headline (didn't bother to read since I like my beef shortly after it stops mooing) that well done steaks more carcinogenic. For the world, reducing red meat is good for the environment and health.
I was reading a study last week on red meat and joint inflammation. Studies the last 15 years actually only have general connection, but that most do is a pretty good indicator. I had a doctor tell me to stop all red meat and milk when I was a teen and experiencing joint pain. It helped, but back then, no internet and not much access to current research. Here we are 45+ years later, and still no strong proof and some show that reducing carbs with increased LEAN red meat actually decreased inflammation.
However, we then get this
Science Catch-up. Red Meat And Gut Inflammation: Harvard Study ...
Jan 18, 2017 - Red meat and gut inflammation: Harvard study. According this new Harvard study involving 46,500 participants, eating high amounts of red meat daily might be a risk factor for gut inflammation and the development of diverticulitis. <<
So no one has absolute proof, but my money is on reducing red meat is more likely to be healthier than not. I just don't rule out all meat (ie fish and fowl) as getting enough protein is pretty hard and we don't have enough hard research for ME to go vegetarian. But I'm open to it and glad you are having success.
