Khloe may be the Kardashian with the supersize fitness closet, and Kylie’s the sister with the big time Puma deal, but even casual Kardashian viewers (come on, the show is always on) know that Kourtney’s the most health-conscious of the clan. In a new interview with Cosmopolitan, she says she only eats all-natural foods—and makes sure her kids do too.

She also avoids other inflammation-causing foods: “We try to do gluten- and dairy-free [at home],” she says. “I’ll make exceptions once in awhile, and I want them to make their own decisions. I’ll remind them, ‘Well, the last time you had ice cream, your tummy hurt. Are you sure you want it?’ But if we’re at Disneyland, we’re definitely gonna eat churros. You have to live a little bit.”

Kardashian has also perfected her morning smoothie recipe. “I have my avocado shake pretty much every day,” she says. Want her recipe? She blends avocado, banana, spinach, and almond milk. Low sugar, simple, and sweet.

Even though she’s health conscious, she’s not body obsessed—and she doesn’t want her kids to be either. Kardashian tells the magazine that she doesn’t use the word “fat” around her daughter.

“They say if a mother is confident about her body that the daughters are way more likely to not have eating disorders,” she says. “I’m fine about my body but I’ll notice little things. If I’m like, ‘Ugh, I hate this outfit! I’m changing!’ My daughter will try on tons of outfits before she’s happy.” Preach, girl.
