Core Tip
Core tip: Gastrointestinal (GI) discomforts were common in Chinese urban elders. Female gender, lower education level, and lower family income were associated more severe GI discomforts. Having a chronic disease and having a GI-related disease were associated with GI discomforts. GI discomforts were associated with the choice of food. Participants with GI discomforts had a significantly lower bean intake and marginally lower dairy product intake, which bring a potential risk of insufficient protein intake and consequently lead to the reducing of muscle.
