Objectives: To examine the association of almond snack consumption with risk factors of cardiovascular disease (CVD) in a UK adult population from the National Diet and Nutrition Survey (NDNS) rolling programme 2008-2014.
Methods: Cross-sectional analysis was conducted using NDNS 2008-2014 data from 4,738 adults (≥19y) who completed a 4-d estimated food diary. Almond snack consumption was defined as average intake of any amount of 1) kernel only (K), 2) kernel only plus the proportion of almond kernels in mixed nuts (M). Specific data on the amount of almonds in mixed nut products were not available so data were estimated from the average proportion of almonds in UK commercial mixed nut products. Comparison of the means of CVD risk markers, including body mass index (BMI); waist circumference (WC); systolic and diastolic blood pressure (SBP & DBP); total cholesterol (TC); triglycerides (TAG); high density lipoprotein (HDL-C); low density lipoprotein (LDL-C); TC:HDL-C; and C-reactive protein (CRP) between almond snack consumers and non-consumers was performed using analysis of covariance (ANCOVA) by adjusting for covariates (age, sex, region, ethnicity, socio-economic and smoking status, and energy intake). Multivariate linear regression models were used to investigate associations of almond snack consumption with these CVD risk markers, including the covariates. Transformation was conducted for non-normally distributed data.
Results: Almond snack consumers, both K and M, had significantly lower BMI (p=0.047 (K), p=0.035 (M)); WC (p=0.002 (K and M)); and CRP (p=0.047 (K), p=0.020 (M)) compared to non-consumers, results shown in Table 1. In addition, M had significantly lower SBP (p=0.004) and higher HDL-C (p=0.004). Fully adjusted regression analysis showed that increments in almond snack consumption (g/1000 kcal of total energy intake) did not statistically change these markers.
Conclusion: Almond snack consumers may have a more favourable CVD risk profile but there is no clear linear relationship between almond snack intake and markers of CVD.
