It was a gradual thing. I never liked the taste of red meat, but enjoyed fish and chicken. So I cut red meat out pretty early (as soon as my parents stopped making me sit at the table to finish the meal).

Later, as I learned more about factory farming and the treatment of chickens in factory farms, I stopped eating chicken and was just left with fish. And finally I learned more about fish farming and overfishing and decided to just remove fish as well. That full vegetarian switch happened over ten years ago now.

I'm currently finding myself in the midst of minimizing egg and dairy consumption as well. I don't buy normal milk anymore, having found a great alternative that I enjoy. I rarely eat real cheese, opting for vegan alternatives since there's quite a few great tasting options now. But I'm not super strict about it, especially when eating out.
