Consumption of Fruits, Vegetables, and Nuts Can Be Increased When Multitasking with Screen Devices.

Past research shows that people overconsume energy-dense, nutrient-poor (EDNP) foods when they are not paying attention to environmental cues that encourage consumption. Very little is known about the mindless consumption of nutritious foods (herein referred to as preferred foods). Using dual-processing, limited capacity, and mood management models and theories, this study explored whether people misreport the selection of preferred and EDNP foods under differing levels of distraction created by screen media device use. Participants freely grazed on EDNP and preferred snacks while either watching TV (one screen) or multitasking with two or three screens (TV, iPod, laptop computer). Participants under-reported the number of preferred foods they selected for consumption in the three-screen multitasking conditions more than in one- and two-screen conditions. They under-reported the selection of preferred snacks more than EDNP snacks in the three-screen conditions. The under-reporting of snack selection was greater in one three-screen condition (TV+texting+online shopping) (which was evaluated as highly arousing and pleasant), than in the other three-screen condition (TV+texting+online reading) (which was rated as highly arousing but less pleasant). Compared to participants with weaker health beliefs, those with stronger beliefs about healthy lifestyle said they were more rational in selecting preferred snacks. Findings show that people sometimes eat greater amounts of preferred foods than they realize, when they are multitasking with screen devices. By surrounding oneself with snack-size fruits, vegetables, and nuts in multitasking situations, mindless eating could be a powerful nudge to facilitate greater consumption of preferred foods to combat health concerns.
