Natural Health Magazine

The Kardashians may be known for their glitzy lifestyle, but off camera, eldest sister Kourtney Kardashian is closer to granola girl than glamour queen.

The mother of two, with another on the way, opened up to Natural Health's September/October issue about her love of yoga, organic food, Ayurvedic cooking and gentle beauty products.

"I pick apart everyone's pantries," she told the magazine about trying to get her famous relatives on board with her clean lifestyle. "They think I'm super-annoying."

While Kardashian, 35, didn't grow up eating organic foods, she discovered them once she began having kids.

"Starting off, I was big on breastfeeding; I nursed my first for 14 months and my second for 16," Kardashian said about Mason, now almost 5, and Penelope, 2. "That was important to me. Then I began making their baby food myself, all of it organic. After that, I was super cautious about what to introduce into their diets. I called a bunch of the restaurants in my neighborhood that I had assumed served all-organic food, and so many didn't!"

Kardashian discovered Ayurveda cooking after doing a cleanse and meeting her yoga teacher.

"We would do yoga for an hour and then she'd stay for another hour and cook with me," the reality star said. "That's where I got all of my rules. In our house, we do everything whole: whole milk and full-fat cheeses. And I use ghee and coconut oil for cooking."

Kardashian also turns to her Ayurvedic friends for health advice for her kids, though she has no problem consulting their pediatrician and giving them conventional medication when necessary.

The expectant mom also gives in to cravings from time to time. "I develop a thing for Nilla Wafer cookies every time. I have no idea why! I've also been into cheese and pickle sandwiches. Everyone thinks I'm gross when I order them."

Well into her third pregnancy, Kardashian said she's ready to try yoga again after starting during her last pregnancy.

"I was anxious, and it just helped me feel calm," she said.

Staying calm and grounded while constantly in the public eye can't be easy, so Kardashian sets boundaries sometimes.

"I'll set times, like, 'On this day, I need everyone to leave me alone,'" she told Natural Health. "Being able to communicate that is important. I do become a recluse once in a while. It's so nice to just be at home and to not have to deal with the outside world."

And since having children she shuts out more of the outside world, ignoring the tabloids and turning off Google Alerts.

"I'm busy with the kids, and they show you what life's about, what's really important," Kardashian said. "They make it really easy for me not to pay attention."
