is it healthier to eat no meat?

[FlatAssembler]

Even if that's true, avoiding heme iron still seems like a good deal to me. People rarely die of anemia, but people commonly die of colon cancer. So having a slightly increased risk of anemia in order to have a slightly lower risk of colon cancer seems like a good thing.

By semi-vegetarians, I meant people who avoid red meat.

Death is not the only issue with anemia you nitwit.

Having enough healthy red blood cells means that your organs get the oxygen they need.

Oxygen tends to be sort of important to your overall health.

Then we must have a very different definition of a healthy diet. By "healthy diet", I mean one that reduces overall mortality.
