Jessica Chastain

The Help star has been a vegan since 2007 and regularly uses her platform to speak openly about her lifestyle choice.

In an interview with W Magazine in 2017, the actress said she was initially a pescatarian but decided to become a vegan because she was really low on energy.

I found myself going to veganism because a friend of mine had a two-week vegan food delivery program she wasnt going to use so I used it, and immediately I just had more energy than Ive ever had in my life she told the publication. I said okay, Im going to just listen to my body now. Being vegan was not anything I ever wanted to be. I just really was listening to what my body was telling me.

A year later, she told the same publication that she was concerned her veganism would make others annoyed, especially her in-laws.

In the beginning, I would say I'm vegan, she explained. Which is like the worst thing. I don't eat 10 meals and I'm vegan. I would say, 'I'm sorry I can't eat that,' and [my mother-in-law] would say, No problem, we have fish.
