The educational TV show for kids "Sesame Street" will celebrate its 40th season with a guest appearance by First Lady Michelle Obama, (26) who will talk up the benefits of gardening and healthy eating. Mrs. Obama talks to young children as she prepares to plant tomato, cucumber and lettuce (莴苣) seeds. "All these seeds need to grow are sun, soil and water," the first lady says. "If you eat these healthy foods, you’re going to grow up to be big and strong, like me. I know you’re going to like these vegetables, because in addition to being healthy, they really taste great!" says Mrs. Obama. The appearance is designed to promote Mrs. Obama’s healthy living style by encouraging Americans to improve their eating and exercise habits.

In Prevention, Mrs. Obama discusses her personal fitness routine, describing how she rises at 4:30 a.m. to exercise and how she tries very hard to get rid of the delicious pies from the White House kitchen. (28)"When I was younger, I could eat whatever I wanted, as long as I exercised," said Mrs. Obama, who is 45, in the interview with Prevention. "So I’m sort of adjusting to the natural progression of the physical limitations that come with being in your 40s," she said. (29)"I try to have no absolute nos," Mrs. Obama continued. "I love French fries. I like a good burger, and I like pie. And that’s OK. I would be depressed if I felt I could never eat the things that I love."
