Abstract

Abstract: Given the limited research on dietary insulin load (DIL), we examined DIL in relation to cardiovascular risk factors and inflammatory biomarkers in elderly men. For the present cross-sectional study, we recruited 357 elderly men. Dietary intake was assessed using FFQ. DIL was estimated by multiplying the insulin index of each food by its energy content and frequency of consumption and then summing the final value of all food items. After adjustment for covariates, a significant positive association was observed between high DIL with fasting blood sugar (FBS) levels (OR: 7·52; 95 % CI 3·38, 16·75; P =0·0001) and high-sensitive C-reactive protein (hs-CRP) (OR: 3·03; 95 % CI 1·54, 5·94; P =0·001). However, there was no association between high DIL and BMI (OR: 1·43; 95 % CI 0·75, 2·75; P =0·27), serum TAG level (OR: 0·82; 95 % CI 0·26, 2·59; P =0·73), HDL-cholesterol (OR: 2·03; 95 % CI 0·79, 5·23; P =0·13) and fibrinogen (OR: 1·57; 95 % CI 0·80, 3·06; P =0·18). Overall, elderly men with high DIL had higher FBS and hs-CRP levels than those with low DIL. Future studies are needed to clarify the association between DIL and other cardiovascular risk factors in both men and women.
