What Is the Cost of Nutrition?

Would you eat more fruits and vegetables if you were paid to do so?

In a recent study published in the Journal of the Academy of Nutrition and Dietetics, 2,292 elementary school students in Utah were rewarded through praise or prizes based on eating fruits and vegetables (Morrill et al., 2015).

I was intrigued, as I live the constant struggle of trying to get my nine-year-old son to eat anything that has any resemblance of a whole food. 

I set out to do my own home-based “science” experiment. The methodology was not well thought out, but I laid a banana down in front of a boy who has refused to eat bananas since he learned the word “no.” I told him I would pay him $2 to eat the banana.

He refused, but after approximately 24 hours, he returned to see if the deal was still negotiable as he needed $2 for a video game purchase. He ate the banana. He didn’t gag. He didn’t act like he was going to die. He ate it AND he liked it.

The Morrill et al. (2015) study also found an increase in the consumption of fruits and vegetables during the study, especially in those that received a tangible prizes.

Unfortunately, after a six-month follow-up, the researchers did not see the students maintaining this higher consumption. I can report that my “home-based” study is still experiencing a significant increase in banana consumption and now I seek ways to continue expanding his healthy food choices. I am in a constant struggle to identify ways to make healthy food choices an intrinsic desire for my family.

Early in my career and before I was a mother, I taught a college nutrition course. I recall when I taught about the nutrition of children, I spoke about how food should not be a struggle between the parent and child. I also shared that kids will eat what they are given and what they see their parents eating.

I still believe this; however, it is not as easy as I thought it would be.

How can we encourage healthy choices for our families and ourselves for our lifetime?
