See, this is a personal decision.
It doesn't matter whether humans can digest meat or not. To me, killing and eating another animal is just unacceptable. And, I find the halal method barbaric and inhumane. I cannot cause suffering to another animal just to enjoy the taste of its meat. And that is my personal opinion, which is not influenced by any religious beliefs.
In fact, a lot of Hindus eat meat (including beef). Animal sacrifice was (and perhaps still is) quite common during Hindu yagnas / prayer ceremonies. In Bengal and Orissa, fish is served during durga puja.
But, in my opinion, if an animal is to be killed (for population control, dinner, or whatever), then it should be carried out instantaneously causing minimal pain. Unfortunately, halal slaughter is often not executed properly which causes great agony to the animal.
Anyways, we're going way off-topic here.
