It has been for me. As a fellow tea enjoyer, lung function, gut health, a melting away of aching joints and physical malaise, seasonal allergy alleviation, and a shockingly boosted immune system are all benefits that I've personally enjoyed since going fully plant-based. Most likely heart benefits as well, but I won't know for sure until I get my cholesterol levels tested.

But of course personal anecdotes are not valid evidence. Which is fine, because the science largely favors diets that are at least mostly plant-centric anyway.
