Dietary protein from different food sources, incident metabolic syndrome and changes in its components: An 11-year longitudinal study in healthy community-dwelling adults

Abstract

Background & aims: Limited data are available on the relationship of protein from different food sources with metabolic syndrome (MetS) or changes in its components. We aimed to prospectively examine the relationships of protein intakes from animal, plant and major food groups with incident MetS and changes in its components. Methods: 5324 participants from the Melbourne Collaborative Cohort Study, who were free of cardiovascular disease, cancer, hyperlipidaemia, elevated plasma glucose, elevated blood pressure and elevated waist circumference (WC) at baseline (1990–1994), were included in the present investigation. Dietary intake was assessed using a validated 121-item Food Frequency Questi..
