Increasing vegetable intake in Mexican-American youth: a randomized controlled trial

Area of Science:

• Nutrition Science
• Pediatric Health
• Behavioral Science

Background:

• Youth vegetable intake is below recommended health guidelines.
• Low consumption is a significant public health concern.
• Effective strategies are needed to improve children's diets.

Purpose of the Study:

• To compare two methods for increasing vegetable consumption in children.
• To evaluate the effectiveness of pairing vegetables with a preferred taste versus exposure alone.
• To assess changes in vegetable consumption quantity and variety.

Main Methods:

• A randomized controlled trial involving 78 Mexican-American middle schoolers in Houston, TX.
• Participants were assigned to either a pairing condition (vegetables with peanut butter) or an exposure-only condition.
• Interventions were delivered weekly in a nutrition class over 4 months.

Main Results:

• The pairing condition showed significant increases in vegetable consumption (P<0.001).
• Participants in the pairing group also demonstrated significant increases in vegetable variety consumed (P<0.001).
• The pairing method was superior to the exposure-only method.

Conclusions:

• Pairing vegetables with a preferred taste, like peanut butter, is an effective strategy to increase consumption.
• This technique is particularly beneficial for children resistant to eating vegetables.
• Findings support using taste-pairing interventions in pediatric nutrition programs.
