RCT on the Neurobehavioral Effects of Fruits and Vegetables in Shanghai Children

The intervention includes the healthy breakfast plan (daily delivery of balanced breakfast containing at least one piece of fruits, vegetables and other regular diet). Meals were centrally prepared by a professional catering service and delivered every morning, seven days a week, to participants' homes, ensuring consistency in portion size and quality. The selection of fruits and vegetables will consider seasonal availability to ensure freshness and variety. Nutrient density and adequacy will be monitored throughout the intervention period, with adjustments made as needed to maintain the nutritional integrity of the meals. Compliance will be tracked through daily logs and periodic assessments, ensuring that participants are consistently consuming the provided meals. This intervention is specifically designed to investigate the neurobehavioral impact of increased fruit and vegetable intake in a controlled and measurable manner.
