What’s the best way to get all the vitamins and minerals you need each day? For adults who do not eat enough fruits and vegetables, it may be to take dietary supplements and a multivitamin. For kids, research has shown that you can simply trick them into eating more produce.

How is this possible? A study published in the American Journal of Clinical Nutrition recently revealed the secret. You simply puree vegetables and sneak them into the foods you serve at dinner.

Researchers from Pennsylvania State University adopted this strategy and used it to good effect, according to the report. The team tried serving vegetable-supplemented dishes to 39 children between the ages of 3 and 6.

These entrees included zucchini bread, pasta with a tomato sauce and chicken noodle casserole, covering all three meals in a day. Scientists pureed carrots, zucchini, broccoli, squash and tomatoes, and added them to these dishes.

“We were pleased to find that the children found the vegetable-enhanced versions to be equally acceptable to the standard recipes,” lead author Maureen Spill reported. She added that, by eating such meals, the participating kids consumed twice the base amount of vegetables and ate 11 percent fewer calories in a day.
