For instance, did you know the No. 10 Stewart-Haas Racing driver can't eat wheat, gluten, dairy, eggs and yeast? Talk about a strict diet. Patrick relies on Lärabars for an extra energy boost during crazy race weekends.
Ever notice Patrick's signature aviator sunglasses she always sports at the track? That's just another accessory that spilled out of her Reed Krakoff shoulder bag.
"Aviator sunglasses fit my face really well, so I like to stick to that shape," Patrick told the magazine. "I always wear my Revo pair with mirrored lenses, and I even designed a Revo line available at Sunglass Hut."
Hear that, Danica fans? Coming fall 2014 you could be sporting a pair from the Danica Patrick Collection.
Like most women, Patrick is prepared for anything and the contents of her bag reflect that.
"I don't have a desk job -- I spend at least four nights a week away from home," Patrick explained. "So I have to be prepared with all the essentials: nail clippers, Tylenol, Tums, tampons, floss. I'm ready for anything."
Along with all of those goodies, Patrick keeps a black Sharpie handy because you never know when you might bump into a fan who wants something signed, and a pen just won't do.
