The Cheers star swears by his hardcore vegetarian diet and is known for providing his movie co-stars with alternatives to meat on set.
Now Harrelson and his wife Laura are appealing to Congress to bring similar practices into the lunchroom by backing the Healthy School Meals Act of 2010, which seeks to add vegetarian food and non-dairy beverages to cafeterias.
A letter from the couple to Congress reads, "As parents, we ask you to support HR 4870, the Healthy School Meals Act of 2010. We know from watching our own children grow up that eating habits children develop early on stick with them for life. All too often, young people are offered processed meats and cheese and other greasy, high-fat, high-cholesterol foods.
"The Healthy School Meals Act will help children develop better eating habits, provide healthful plant-based options that naturally contain no cholesterol, are low in saturated fat and high in fibre, enabling schools to reach high nutrition standards easily. The legislation gives schools the incentive and ability to address the health problems that are harming our children and overburdening our health systems."
Scarlett Johansson also pledged her support for the bill in a letter to a California congressman in March (10).
