A、Studied a lot of international journals. B、Estimated food consumption of undergraduate students. C、Spent a lot of time eating

University of Houston associate professor Temple Northup has looked at the relationship between food consumption and the number of hours spent in front of the television. [5]Northup’s study, published in The International Journal of Communication and Health, surveyed 591 undergraduate students on their viewing, eating and drinking habits. Consistent with past studies, he found that the more people watched TV, the more they engaged in unhealthy eating. "The explanation is relatively straightforward—[6]the act of watching TV is an activity that encourages snacking," says Northup.
    Lots of research shows mindless eating plays a prominent role in how much we digest while distracted with what is happening on screen. "Watching TV while eating is also common behavior," says Lilian Cheung, director of health promotion and communication at Harvard School of Public Health. [7] "When we are distracted while eating, or eating mindlessly, we are not paying full attention to the food in front of us, and miss the cues letting us know that we are full."
