is it healthier to eat no meat?

[FlatAssembler]

It is healthier to eat no red meat as heme iron is found almost exclusively in red meat. Heme iron is widely agreed to be causing colon cancer, and there is quite a bit of evidence that it somehow causes breast cancer as well.

A vegetarian diet is also less likely to be too high in saturated fat and less likely to be deficient in vitamin K, although it goes without saying that it doesn't have to be (some vegetarians eat a lot of coconut-based products, which are very high in saturated fat).

Bold mine - where do you get this information?  My breast cancer doctor is a researcher as well.  She didn't ever mention the consumption of meat during the five years that I saw her.

A 2019 review found that heme iron intake is associated with increased breast cancer risk.
