According to a new study published in the journal Public Health Nutrition, individuals who consume tree nut snacks (TNS) have better dietary quality and fewer risk factors for cardiovascular disease (CVD).

Researchers conducted a cross-sectional analysis of 4738 UK adults from the National Diet and Nutrition Survey 2008-2014 to determine the association of TNS consumption with quality of diet and CVD risk markers.

The prevalence of TNS consumption in the UK adult population was estimated to be ~10 per cent. TNS consumers had higher modified Mediterranean Diet Score and Healthy Diet Score than non-consumers. TNS consumers also had lower body mass index, waist circumference, systolic blood pressure and diastolic blood pressure and higher high-density lipoprotein cholesterol than non-consumers.

TNS consumption was associated with a higher intake of total fat; mono-, n-3 and n-6 polyunsaturated fatty acids; fibre; vitamins (A, C, E, thiamine, folate, pantothenic acid and biotin); and minerals (potassium, magnesium, phosphorus, manganese, zinc, copper, selenium and iron) and a lower intake of saturated and trans fatty acids, total carbohydrate, starch, free sugar, sodium and chloride.

The authors recommend that "tree nuts should replace high refined carbohydrate-based snacks as part of a healthy diet."
