Which U.S. First Lady appeared on Sesame Street in 2011 to promote healthy eating?

The U.S. First Lady associated with Sesame Street’s healthy-eating message was Michelle Obama. During her time as First Lady, she promoted nutritious food, gardening, and children’s health through her Let’s Move! initiative and appearances with Sesame Street characters.

Obama appeared on Sesame Street programs to encourage children to grow and eat vegetables. In one well-known segment, she worked with Elmo and several children in a garden, discussing how fresh foods grow and why healthy choices matter. Her public-health work connected television lessons with the White House Kitchen Garden, which the Obamas planted on the South Lawn in 2009.

Michelle Obama launched Let’s Move! in 2010 to address childhood obesity through healthier eating and physical activity. She also later joined Elmo and Rosita for a 2013 announcement promoting fresh fruits and vegetables. These related appearances and campaigns can cause the dates to be confused, but Michelle Obama is the canonical answer to the question. Eleanor Roosevelt is associated with an earlier White House victory garden, not this Sesame Street health campaign.
