is it healthier to eat no meat?

All vegetarians are at higher risk for iron deficiency, Flat.  That's the main thing to weigh or manage in light of whatever benefit you hope to extract from a vegetarian diet.  Semi vegetarians less so because of that semi bit.  I do love the word semi vegetarian, though.  A beef burrito with cheese is my favorite semi vegetarian dish.

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.
