Kids and Kale Chips
Scientifically proven not to make them go, “Eeeeew.”
Kale is succeeding where spinach and other green things have consistently failed: getting swallowed by children. The key is to bake the kale into crispy chips. In a series of taste tests conducted in Montana, it was determined that kids will eagerly turn their mouths green with extra helpings.
The evidence is convincing enough that the food purchaser for Missoula County Public Schools placed a kale order with a local farm, to be delivered for the fall term. Edward Christensen, assistant supervisor of food and nutrition for Missoula schools, says the taste test was the final and most crucial hurdle, but the fact that kale is so healthful and grows so well in his region makes it especially attractive. "Kale is disease- and pest-resistant and cold tolerant. It's the low-hanging fruit of Montana."
Jason Mandala is the community education director for Garden City Harvest, the nonprofit Missoula farm that got the contract to grow kale for the schools. It was Mandala who sold Christensen on chips as a kid-friendly way to serve a dark-green leafy vegetable in school cafeterias. Though Christensen was impressed, his opinion wasn't the only one that counted. Conducting successful taste tests at area schools made it a done deal.
"The kids gobbled them up," Mandala says. "They taste similar to a potato chip, but they're a lot better for you."
Mandala just applied for a USDA grant to fund a project that would use school district land to grow even more food for students. Plans include a project developed by students at Missoula's Sentinel High School that aims to create positive environmental and public-health changes by molding consumer habits at a young age. Consumer habits, in this case, would mean kale appreciation. The plan includes greenhouses outfitted with grow lights and hydroponic gear to be donated by the Drug Enforcement Agency.
The joys of calcium absorption remain a tough sell. More often he just calls them "ninja chips," and lets the flavor and crunch seal the deal.
Such repurposing of confiscated marijuana-farming equipment is not as unusual as you might think, says Mary Stein, associate director of the National Farm to School Network. "That's happening in several places around the country," she tells me. And it's just one example of how individual farm-to-school programs can adapt to local opportunities and conditions. "Farm-to-school programs are as different as the communities they're part of across the country. In Sitka, Alaska, fish to school is a big deal."
Mandala agrees that different geographies have their own low-hanging fruit, and it's up to locals to find it. "You have to identify what grows well, wherever you are, and what your land situation is, and how much you need, and what kids are going to eat," he says.
With the contract in place, Mandala has seeded more than 500 kale plants. Early summer, it turns out, is a great time to start a fall crop of kale. The seeds can be planted directly in the ground or started indoors, as Mandala did with his red bore and winter bore kale, which are the best varieties for chip-making, he says. Their extra-curly leaves grip oil and flavorings, while their high fiber (even for kale) makes for a solid crunch. Plus, the shape of the leaf lends itself to easy stripping of the leaf's flesh from the central vein, he says. But any kale would work, and all kale is good.
In addition to the chips' pleasing taste, kale's many health properties provide ample opportunity for creative storytelling to help entice the students.
"We tell kids it will help them see in the dark," Mandala says, referring to kale's high content of phytonutrients, which are important in a number of ways, including eye health.
Kale is also high in calcium, and it’s one of the best sources of vitamin K, which helps the body absorb calcium. "Most of the calcium in milk goes through your body, and most of the calcium in kale gets absorbed by your body," he says, though he admits that the joys of calcium absorption remain a tough sell.
