Objectives: To examine the association of almond snack consumption with nutrient intake, nutrient adequacy and diet quality in a UK adult population from the National Diet and Nutrition Survey (NDNS) 2008-2014.
Methods: Cross-sectional analysis was conducted using data from 4,738 adults (≥19 y) who completed a 4-d 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. Nutrient intakes were calculated and percentages of the intakes below the Estimated Average Requirement (EAR), Dietary Reference Values (DRV) or Reference Nutrient Intakes (RNI) were determined. To estimate diet quality, modified Mediterranean Diet Score (MDS), modified Healthy Diet Score (HDS) and Eating Choices Index (ECI) were applied. Dietary patterns were also derived via principle component analysis (PCA) using 60 food groups. Multivariate linear regression models were used to investigate associations of almond snack consumption with diet quality including covariates (age, sex, region, ethnicity, socio-economic and smoking status and energy intake).
Results: K and M consumers had significantly higher intakes of cis-MUFA, n-6 PUFA, dietary fibre, vitamin E, folate, vitamin C, potassium, magnesium, phosphorus, iron, copper and manganese than non-consumers. A smaller percentage of K and M consumers than non-consumers were below the EAR for vitamins A, riboflavin, folate, vitamin C, calcium, magnesium, iron and zinc; the DRV for dietary fibre; and the RNI for potassium, copper, iodine and selenium. MDS, HDS and ECI scores were significantly higher in K and M consumers. Regression analysis showed that increments in almond snack consumption (g/1000 kcal of total energy intake) significantly and positively changed MDS, HDS and ECI scores by 0.112 (K) and 0.134 (M), 0.110 (K) and 0.105 (M), and 0.103 (K) and 0.115 (M) respectively. Six dietary patterns were derived by PCA in the total population, and almond snack consumption was associated with a Mediterranean-style pattern.
Conclusion: Almond snack consumers are more likely to meet dietary guidelines.
