Abstract
Background: With the continuous elevation of living standards, dining-out behavior has become increasingly prevalent among urban residents. The acceleration of lifestyle rhythms has prompted fast food to emerge as a frequently considered dietary option for urban residents when dining out. This study aims to investigate the current status and characteristics of dining-out habits for fast-food consumption among urban residents in Beijing. Methods: Urban residents in Beijing were selected using a stratified sampling method to survey restaurants. A database of fast-food items was created, and data were collected through a combination of field observations and qualitative interviews. Nutrient intake from fast food was systematically analyzed. Results: Residents consuming fast food while dining out exhibited high per-meal energy intake (737.5 kcal) and protein (44.8 g) consumption; however, the intakes of vitamin A (147.6 μg RAE), vitamin C (22 mg), vitamin E (3.2 mg), and calcium (89.5 mg) were inadequate. Western fast-food meals had higher protein (57.2 g) and sodium (251.5 mg) content compared to Chinese fast food. Conclusions: This study provides essential data to guide urban residents toward rational dining choices, offering key insights for the fast-food industry to develop balanced meal options.
