Shamrock Farms, Subway Restaurants and actress and singer-songwriter Leighton Meester once again joined forces to support Feeding America, the largest domestic hunger-relief organization in the United States, to help provide meals for people in need in the new year.

Phoenix-based Shamrock Farms said it teamed up with Subway to donate $1 to Feeding America for every Shamrock Farms milk purchased with a Subway Fresh Fit For Kids meal at participating U.S. restaurants to mark National Milk Day on Jan. 11. For every $1 donated, Feeding America is able to provide at least 10 meals to help fight hunger in communities across the country.

"Food insecurity is an issue I continue to be truly passionate about, as it's one that hits close to home for me. So, I am very proud to work with Subway and Shamrock Farms again to help more families in need," said Leighton Meester, Feeding America Entertainment Council member. "Last year, with the support of families across the U.S. simply purchasing Shamrock Farms milk with a kid's meal at Subway Restaurants, Feeding America was able to provide 350,000 meals, and it's our hope that people will join in again to help deliver more good to people that need it."

A top food source for protein, calcium and vitamin D, milk continues to be one of the most requested items at food banks, Shamrock Farms said. While critical to fueling growing bodies and minds, basic staples such as milk are often missing from the diets of many children facing hunger.

"We're honored to continue our partnership and work towards our shared mission of hunger relief for the second year in a row," said Ann Ocaña, chief marketing officer for Shamrock Farms. "Our Shamrock Farms milk provides essential nutrients and protein for growing children and adults, so National Milk Day is a great opportunity to help nourish families and give back."
