Last September I described how surprisingly unhealthy foods–Rice Krispies treats, donuts, and Pop Tarts–can be fed to children in federally funded daycare meal programs.

Now, federal daycare meals are about to get their first nutritional overhaul since 1968. Under the same 2010 legislation mandating healthier school meals, the U.S. Department of Agriculture (USDA) was charged with coming up with improved standards for the Child and Adult Care Food Program (CACFP), the program that oversees daycare food as well as meals served in after-school snack programs, adult group homes, and similar facilities.

The USDA released its proposed new CACFP rules in January and the results are decidedly mixed.

On the one hand, the new rules do bring improvements. CACFP providers will now be required to serve children a greater variety of fruits and vegetables, more whole grains, and less sugar and fat–at least as compared to the old meal standards. The rules also include greater support for breastfeeding mothers, the acceptance of tofu as a meat substitute, and requirements that water be made available at meals, that “grain-based desserts” like cookies no longer fulfill children’s daily grain requirement, and that breakfast cereals contain less sugar.

That’s all good news. But there are still some glaring nutritional deficiencies in the proposed rules. Here are some examples:

• CACFP providers may not fry foods on their own premises, but may still serve foods fried off-site, whether by manufacturers of products like frozen French fries or deep-fried fish sticks, or by a third-party caterer. And there’s no limit on the number of times fried foods may be served each week.

• For children over one year of age, all fruit or vegetable requirements may be fulfilled by serving 100 percent fruit or vegetable juice, and while two juices may not be served at the same meal, there’s otherwise no limit on the number of times juice may be served each day For children over one year of age, snacks must contain two meal components, but neither has to be a fruit or vegetable. And there’s no affirmative requirement that any of the vegetables served include dark green or red/orange vegetables.

• Children over one year of age may be served flavored milk at every meal, without any limits on sugar content, so long as the flavored milk is fat-free.

• Children need only be served one whole grain or “whole-grain rich” (at least 50 percent whole grain) food a day, and the rest of a child’s grain allotment may consist of enriched white flour products. And while USDA has yet to provide guidance on what foods constitute “grain-based desserts,” it seems likely (based on acceptable breakfast foods offered in the federal School Breakfast Program) that items such as Pop Tarts and sweet rolls, particularly if whole-grain rich, will still be permissible. There’s no limit on the number of times processed or fattier meats may be served each week.

Many of these surprisingly low nutritional standards run counter to recommendations from the Institute of Medicine (IOM), which provided the USDA with science-based advice for overhauling the CACFP, just as it did for school meals. But the USDA admits that in some cases it chose to ignore IOM nutritional recommendations due to likely “increased cost or complexity” in implementing them.

Instead, the USDA offers CACFP providers a list of recommended “best practices” such as offering children more whole grains, not serving any flavored milk, and limiting juice to once a day and fried foods to once a week.  But it also makes clear that such practices are to be implemented “at the sole discretion of the provider.”  So if a daycare provider chose to disregard all of USDA’s “best practices,” here’s what acceptable meals for a child aged 3-5 could still look like under the new proposed meal standards:
