Bhubaneswar (Odisha): Turns out, high school students prefer their vegetables seasoned with spices rather than plain.
Students like their vegetables spiced up
The researchers asked high school students to rate the taste of a variety of vegetables seasoned with either oil or salt or a blend of herbs and spices developed specifically for each vegetable. The majority of the students preferred the seasoned version of most of the veggies, despite the fact that many of the seasoning blends were new to them.
Kathleen Keller, associate professor of nutritional sciences, said that schools that serve vegetables that are more appealing may ultimately cut down on the amount of food that is thrown out.
"Despite the fact that many of the kids hadn't previously been exposed to a lot of different herbs and spices, our results showed that they liked and preferred the seasoned vegetables to the plain ones," Keller said. "I think that if schools were to implement these simple recipes, they might have more success than if they just serve vegetables with oil and salt or nothing at all."
Eating enough vegetables is essential for good health. Consuming a lot of veggies has been linked with a reduced risk of both heart disease and some cancers.
While the current Dietary Guidelines for Americans recommend that teens between the ages of 14 and 18 eat between two-and-a-half and four cups of vegetables a day, the researchers said only about 2 percent of American adolescents eat enough.
Schools in the United States that participate in the National School Lunch Program have to follow federal guidelines for what they serve for lunch, including offering a variety of vegetables throughout the week and limiting fat and salt. But offering vegetables doesn't guarantee students will eat them, and discarded vegetables can add up to a lot of wasted food.
"When we talked to the students, we learned the most important thing to them when it came to eating vegetables was the taste," Keller said. "For the school lunch food service workers, they were worried about sticking to the federal guidelines, food waste and making food kids will like without recipes to work from."
The researchers gave the students taste tests to measure how much they liked a variety of plain versus seasoned vegetables. The plain vegetables were prepared with a small amount of oil and salt, while the seasoned vegetables were prepared with a seasoning blend specifically developed for each vegetable. For example, the corn and peas were seasoned with a blend designed to mimic the flavour of nachos.
Taste tests were held for eight different vegetables, with about 100 students participating in each test. All recipes used either frozen or canned vegetables, to make them easy to replicate by the school's food service workers.
The researchers found that overall, the students preferred the seasoned version of the vegetables, except for the sweet potatoes. The seasoned versions of corn and peas, black beans and corn, cauliflower, broccoli, green beans, and carrots were all rated as better tasting than the plain versions.
Keller said that in the future, the researchers will look at whether adding herbs and spices to the vegetables will result in the students eating more vegetables. She also said the results also have broader implications about how parents feed their kids, even from an early age.
"I'm a big proponent of not being afraid to use herbs and spices, even with young kids or toddlers," Keller said. "Even with baby food you can add small amounts of herbs or spices, so they're getting used to the flavours of the family. If you're going to be using these things in the foods you make for your family later on, it doesn't make sense to avoid them when kids are little."
The findings from the study are published in the journal Food Quality and Preference.
