There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

But regarding grizzlies i will contact experts whether they feed on flesh and muscle. But keeping aside about digestive system, I am sure their heart is relatively weaker than other parts of the body. I will study about grizzly and then reply.
Sloth bears have adapted to a diet like many of the anteaters and armadillos' of South America, and the pangolin and aardvark. Neither their teeth and likely not their digestive system ( maybe ) is ready for red meat. With the polar bear, my thoughts are that blubber better fuels his high-energy needs to survive in his harsh environment. Grizzlies and black bears certainly have no trouble devouring red meat.
