Is a Handful an Effective Way to Guide Nut Recommendations?

Dietary guidelines recommend consuming 30 g of nuts per day to reduce the risk of chronic disease. A ‘handful’ is commonly used to guide consumers. Research is lacking on how this translates into actual gram amounts. This study quantified the grams of nuts represented by different portion size measu...

description Dietary guidelines recommend consuming 30 g of nuts per day to reduce the risk of chronic disease. A ‘handful’ is commonly used to guide consumers. Research is lacking on how this translates into actual gram amounts. This study quantified the grams of nuts represented by different portion size measures, including a ‘handful’ and ‘30 g serving’ among 120 participants. Each participant was randomised to a sequence where they received three of six different nut types (from almonds, cashews, hazelnuts, macadamias, peanuts, and walnuts) and were instructed to take a: ‘usual serving’, ‘handful’, ‘small handful’, ‘large handful’, and ‘30 g serving’ of each. Combining all nut types, the median ‘handful’ was 36.3 g, compared to 28.7 g for the estimated ‘30 g serving’ and 24.8 for the ‘usual serving’. The ‘large handful’ was approximately double the ‘handful’ (61.3 g), whereas the ‘small handful’ was about half (16.7 g). Eighty-three percent of portions chosen were at least 80% of the recommended 30 g intake when participants were asked to take a ‘handful’, compared to 63% for the ‘30 g serving’. It appears a ‘handful’ can be used as a practical tool to guide recommended nut intakes, and increases the amount selected compared to instructions to take a ‘30 g serving’.
