But unfortunately, we’re now seeing attempts in Congress to undo so much of what we’ve accomplished on behalf of our children. Take, for example, what’s going on now with the Women, Infants and Children program, known as WIC. This is a federal program designed to provide supplemental nutrition to low-income women and their babies and toddlers. The idea is to fill in the gaps in their diets — to help them buy items like fresh produce that they can’t afford on their own — and give them the nutrition they’re missing.

Right now, the House of Representatives is considering a bill to override science by mandating that white potatoes be included on the list of foods that women can purchase using WIC dollars. Now, there is nothing wrong with potatoes. The problem is that many women and children already consume enough potatoes and not enough of the nutrient-dense fruits and vegetables they need. That’s why the Institute of Medicine — the nonpartisan, scientific body that advises on the standards for WIC — has said that potatoes should not be part of the WIC program.

Unfortunately, this isn’t an isolated occurrence. We’re seeing the same kind of scenario unfold with our school lunch program. Back in 2010, Congress passed the Healthy, Hunger-Free Kids Act, which set higher nutritional standards for school lunches, also based on recommendations from the Institute of Medicine. Today, 90 percent of schools report that they are meeting these new standards. As a result, kids are now getting more fruits, vegetables, whole grains and other foods they need to be healthy.

This is a big win for parents who are working hard to serve their kids balanced meals at home and don’t want their efforts undermined during the day at school. And it’s a big win for all of us since we spend more than $10 billion a year on school lunches and should not be spending those hard-earned taxpayer dollars on junk food for our children.

Yet some members of the House of Representatives are now threatening to roll back these new standards and lower the quality of food our kids get in school. They want to make it optional, not mandatory, for schools to serve fruits and vegetables to our kids. They also want to allow more sodium and fewer whole grains than recommended into school lunches. These issues will be considered when the House Appropriations Committee takes up the annual spending bill for the Agriculture Department on Thursday.
