A big problem Is the red meat. It has been found that consuming red meat increases the risk for cancer. How you cook it also matters. Eating lots of grilled red meat is not good for your health!
Everyone should decrease their consumption of meat. Not just for your healths sake but also for the environment. If everyone limited their meat consumption to just two times a week it would go a long way in helping reduce the damage of climate change.
As far as I know the U.S. Big Mac didn't even contain real meat for a long time but something that's called "boneless lean beef trimmings". Jamie Oliver called it "pink slime" and won a lawsuit against the meat distributor: http://abcnews.go.com/blogs/health/2012/02/01/mcdonalds-announces-end-to-pink-slime-in-burgers/
Astonishing that you can red meat even more unhealthy!
