Transit time is a putative factor implied in the severity of symptoms associated with lactose. OBJECTIVES to elucidate the relation between oroc...

BACKGROUND Relationships between inflammatory bowel disease and lactose containing foods remain controversial and poorly defined regarding symptoms, nutritional outcomes, and epidemiologic associations for lactose maldigestion. METHODS A literature review was performed using Pub Med, Cochrane library and individual references, to extract data on lactose maldigestion prevalence in inflammatory...

Insufficient intake of dairy products is a nutritional problem of concern in China. However, the knowledge, attitude, and practice of consuming dairy products in the Chinese population remain unknown. A total of 1739 subjects from eight cities in China participated in this study. A questionnaire was used to measure knowledge of and attitude toward dairy. A semi-food intake frequency questionnai...
