Dietary protein intake is associated with favorable cardiometabolic risk factors in adults: Tehran Lipid and Glucose Study.
Nutr Res. 2012 Mar; 32(3):169-76.NR

Abstract

In this study, we investigated the hypothesis that dietary protein content and type are related to cardiometabolic risk factors including body mass index, waist circumference (WC), serum triglycerides, high-density lipoprotein cholesterol (HDL-C), serum fasting glucose, and blood pressure. This population-based study was conducted on 2537 subjects aged 19 to 70 years and selected from among participants of the Tehran Lipid and Glucose Study (2006-2008). Dietary data were collected using a validated semiquantitative food frequency questionnaire. Associations between intakes of total protein as well as the animal-to-plant (A/P) protein ratio and cardiometabolic risk factors were analyzed using multivariate linear regression models. Dietary protein intakes were 13.7% and 13.6% of energy, in men and women, respectively; the A/P protein ratio in women was significantly higher than in men (1.8 ± 1.4 vs 1.4 ± 0.9). Body mass index was associated with total protein intake in men (β = 0.14, P = .01) and A/P protein ratio in women (β = 0.075, P = .01). Waist circumference was associated with total protein intake (β = -0.048, P = .03) and A/P protein ratio (β=0.031, P = .05) in women. Serum fasting glucose was associated with both total protein intake (β=0.061 and 0.11, P < .05) and the A/P proteinratio (β = -0.078 and -0.056, P < .05) in both men and women, respectively. Serum HDL-C was associated with total protein intake (β = 0.107 and 0.07, P < .05) in both men and women, whereas diastolic blood pressure in women was associated with total protein intake (β = -0.125, P = .01). In conclusion, higher dietary protein intake was associated with enhanced HDL-C levels, WC, and diastolic BP, and a higher ratio of A/P protein intake was related with lower serum fasting glucose andWC.
