(CNSNews.com) – First lady Michelle Obama told children at the White House's Annual Take Our Daughters and Sons to Work Day on Thursday that her favorite healthy food was pizza and her favorite junk food was French fries.

“So I’m gonna give you my favorite healthy thing to eat, which actually is my favorite thing to eat – pizza. Yes, but usually when I have pizza – alright don’t get mad at me – I do veggie pizzas,” she said in response to a question about her favorite food.

“It’s really good, and they make great pizza here at the White House. So that’s a way that I get the favorite food that I love but also do it in a healthy way so I can eat it whenever I want to, right?” she added.

Mrs. Obama has made fighting childhood obesity her signature issue as first lady through her “Let’s Move” campaign.

The first lady said her favorite unhealthy food is French fries.

“But if I’m really being bad, right? And if I want my favorite junk food – some kids asked me this just the other day – one of my favorite, favorite junk foods is French fries. I love French fries,” Mrs. Obama said.
