According to researchers at the St. Louis University Medical Center, children who eat homegrown fruits and vegetables eat twice as much of fruits and veggies overall, compared to children who don't have access to garden-grown produce. Children who grow up eating produce straight from the garden apparently prefer the taste of fruits and veggies to, say, chocolate bars and other junk-filled goodies, according to researchers. "Whether a food is homegrown makes a difference. Garden produce creates what we call a 'positive food environment,'" says Dr. Debra Haire-Joshu, of the university's Obesity Prevention Center. In addition, children whose homes had gardens had access to greater selections of produce. According to Haire-Joshu, the solution is simple and low cost: getting parents or schools to plant gardens and involve children with growing and cooking food leads to an obvious improvement in diet, and the institution of "good" food habits from a young age.
