"But still, if there was evolution, I think our heart would eventually develop a mechanism to accept more red meat. Just my opinion."

Our bodies, and our hearts, are probably as "evolved" as they need to be for the digestion of meat.

The scenario is this; "With two yoke of oxen, and one spotted hog, a tall Shanghai rooster and an old yeller dog". -- Why the animals?

Because where Sweet Betsy was going, they needed animals and animal products just to survive.

We are more fortunate now. We may, if we choose, eschew the eating of meat altogether. Our dietary variation in most cultures is sufficient to let us remain healthy anyway if we are careful and wise.

Evolution is not the magic wand some may perceive or fear. The heart would be unlikely to change much for dietary reasons. As far as evolution is concerned, you are pretty much on your own after you have produced children. Since heart problems typically surface long after child-bearing occurs, they are not affected directly by evolutionary pressures.

Interesting enough. Something to think about anyway. I still see no real proof of evolution in our lives.

I may not reply right away. I am hiribist hunting on youtube.

This is a good way to spend time:
