While Hanratty plays a cannibal on Yellowjackets, in real life she doesn’t touch any animal products. ​"Everything I'm eating is Beyond Meat, just because I'm vegan, so they just reassure me that every time blood sprays in my face, 'Don't worry! It's vegan!'" she told The Daily Beast.

2. She Takes Care of Her Mental Health

Sammi is incredibly open about her mental health struggles. “I just started new anti anxiety meds and so far so good. A couple of bumps in the road but that’s to be expected when transitioning to new meds. Being out in nature has really helped me this week while my body acclimates.

If you struggle with anxiety, depression, or ADHD I’m right there with you baby!!! We will get through it together,” she captioned a recent Instagram post, wearing a swimsuit while enjoying a waterfall.

“Growing up, I was sick a lot. I had a gut condition that I didn’t realize. I was in and out of hospitals and urgent cares,” Hanratty told The Daily Beast. “I didn’t really know what was wrong with me for most of my life. It’s so crazy because I’ve been working for twenty years now—I started when I was six—and any time I had a break and wasn’t filming, I was sick. It was almost like my body wouldn’t let me be sick when I had work, and the second a weekend came, I would have a fever and we didn’t really know what was going on.” She found out that her health issues were connected to food, and was forced to cut out multiple things from her diet. “So now, I can’t really eat anything. I’m allergic to avocados, cucumbers, broccoli, banana, cinnamon, curry, fennel, ginger. So many things. But now I’m not sick all the time, so… yay!” she added. “So I’m vegan, allergic to over 30 foods, and now I found out I have GERD which means I need to stay away from foods that contain a lot of acid. So I’m just gonna enjoy a big bowl of water for breakfast. Lol time to do some research and see what I can do!” she tweeted.
