NEW YORK (AP) — There’s a new author in the White House: Michelle Obama.

The first lady has signed with the Crown Publishing Group for a book about the garden she started on the South Lawn of the White House and the benefits of healthy eating.

The book, currently untitled, is scheduled to come out in April 2012. Obama received no advance and will donate all proceeds to a charity or charities to be determined.

The White House said the garden has yielded more than 2,000 pounds of fresh fruits and vegetables.

“We’ve gotten food out of the garden, and we can eat it and it’s good,” Obama said Wednesday during a brief telephone interview with The Associated Press. “So we wanted to share the story with the rest of the nation and perhaps with the rest of the world, because we get so many questions about the garden: How did we do it? Why did we do it? How do I do this in my own home or community?”

The first lady, 47, has been an advocate for locally grown food and last year started an anti-obesity campaign, “Let’s Move!” According to Crown, the book will be “inspirational and instructive, and will provide ideas and resources for readers to get involved in the movement to create community, school and urban gardens, support local farmers’ markets, and make small lifestyle changes to achieve big health results.

“Mrs. Obama will also share some of her family’s favorite healthy recipes.”
