If you want to reduce animal suffering, there's a pretty good argument that cows are the last animals/animal products you should stop eating.

You should definitely stop eating eggs, as egg-laying chickens live short, miserable lives where their bodies are destroyed rapidly. Chickens, fish and other small animals in captivity live short, miserable lives, and one family can eat a whole chicken in a day -- thats alot of chicken deaths to eat chicken regularly.

Cows by comparison generally live pretty good lives, better than any wild cattle. They can roam and eat well and socialize, and slaughter is pretty humane compared to being hunted down by predators or dying slowly of an infection, broken leg or other natural cause. And one cow death can feed an entire family for a very long time.
