Let’s hear it for students from St. Ignatius School in Portland, Oregon for promoting healthy eating habits. The school’s second graders were being taught about the Food Pyramid when they heard that comedian and talk show host Jay Leno hadn’t eaten a vegetable since 1969. The students wrote letters to Mr. Leno imploring him to take a renewed look at the Food Pyramid and give veggies another try. Their persuasive writing paid off: Mr. Leno ate a veggie for the first time in 30 years on an episode of “The Tonight Show” this week. If you want to see a clip of the show, visit the school’s Web site at http://www.stignatiusschool.org/today.htm. Principal John Matcovich says the entire letter writing project has been “a memorable example to our students of how powerful their writing can be.”
