There are almost certainly no health benefits.

I consider the ethical considerations to be significant. Many people have had them for a long time; vegetarianism is centuries old in the West and even longer among some cultures. Plenty of other practices that were one time considered ethical by most have come under scrutiny: slavery, racism, etc. I believe that animal suffering may one day be in the same category.

But if you're OK with that, and your primary concern is health, then you can be reasonably sure that there are no advantages on that score.
