WASHINGTON ( CNN ) -- Want to know where the presidential produce comes from ? Washington 's Bancroft Elementary School students help first lady Michelle Obama break ground on the garden . Take a walk past the White House . The answer may be planted right in front of you . First lady Michelle Obama helped break ground on a new White House organic `` kitchen garden '' Friday . It will be the first working garden at 1600 Pennsylvania Ave. since Eleanor Roosevelt planted a so-called `` victory garden '' at the height of World War II . This time , however , the enemy is obesity . The first family is hoping to send a clear message to a fast food-driven nation that often seems to be losing the battle of the bulge . `` We 're just hoping that a lot of families look at us and say this is something that they can do and talk to their own kids about and think a little bit critically about the food choices that they make , '' said Marian Robinson , the president 's mother-in-law . Watch Michelle Obama tell students about the garden » . The first lady told a group of Washington schoolchildren on hand for the occasion that first daughters Sasha and Malia Obama were usually more willing to try fresh fruits and vegetables because fresh produce generally tastes better . `` What I found with my kids [ is that ] if they were involved in planting it and picking it , they were much more curious about giving it a try , '' she added . `` I 've been able to have my kids eat so many different things that they would have never touched if we had bought it at a store because they either met the farmers that grew it , or they saw how it was grown , '' she said . `` They were curious about it and ... usually they liked it . '' The idea of a presidential kitchen garden , used year-round with different seasonal crops , has been strongly promoted by advocates for organic and locally grown food . They argue that the White House garden may help set a positive example for families short on time and money , who are often tempted by cheaper , highly processed food . The presidential garden will be used , among other things , for growing such staples as butterhead and red leaf lettuce , spinach , broccoli , onions , carrots and peas . It will also include a range of herbs , including sage , oregano and rosemary . The garden is one of several additions to the White House South Lawn . A swing set for the first daughters was recently installed near the Oval Office . CNN 's Anne Oblinger contributed to this report .
