Nikodijevic, C.J., Y.C. Probst, S.-Y. Tan, E.P. Neale, 2024. Metabolisable energy from nuts and patterns of nut consumption in the Australian population: a secondary analysis of the 2011–12 National Nutrition and Physical Activity Survey. J Hum Nutr Diet. 37: 538–549. https://doi.org/10.1111/jhn.13278
Background: Nut intake is not associated with increased body weight, which may be explained by their metabolisable energy, among other factors. Therefore, total energy intake may be overestimated among nut consumers. This study aimed to describe the metabolisable energy from nuts and nut consumption patterns in the Australian population. Methods: A nut‐specific database was expanded to include metabolizable energy of nuts (based on nut type and form) and applied to the 2011–12 National Nutrition and Physical Activity Survey (NNPAS). Participants were Australians aged 2 years and older from the 2011–12 NNPAS (n = 12,153, with n = 4,765 nut consumers). Mean metabolisable energy intake was compared with mean energy intake using Atwater factors in nut consumers. Additionally, nut consumption patterns were explored, including the proportion of nuts consumed at meals and snacks. Results: Among nut consumers, mean metabolisable energy from nuts based only on nut type was 241.2 (95% confidence interval [CI]: 232.0, 250.5) kJ/day and mean metabolisable energy considering both nut type and form was 260.7(95% CI: 250.2, 271.2) kJ/day. Energy intake from nuts using Atwater factors was 317.6 (95% CI: 304.8, 330.3) kJ/day. Nuts were more likely to be consumed at snack occasions, with approximately 63% of nut intake occurring as a snack. Conclusion: Application of metabolisable energy to the 2011–12 NNPAS has a significant impact on calculation of energy intake from nuts. Nut consumption patterns identified a majority of nut consumption occurring as snacks. These findings may inform strategies to support nut consumption in Australia.

Nwaru, 2024. Prevalence of tree nut allergy in Europe: A systematic review and meta-analysis. Allergy. 79: 302-323. doi:10.1111/all.15905
In 2014, the European Academy of Allergy and Clinical Immunology (EAACI) published the first systematic review that summarized the prevalence of food allergy (FA) and food sensitization in Europe for studies published 2000–2012. However, only summary estimates for tree nut allergy (TNA) were feasible in that work. In the current update of that systematic review, we summarized the prevalence of tree nut allergy/sensitization to individual tree nuts. Six databases were searched for relevant papers published 2012–2021 and 17 eligible studies were added to the 15 studies already identified between 2000 and 2012, giving a total of 32 studies. Of the investigated tree nuts, meta-analysis was possible for hazelnut, walnut, almond, and in few cases, for cashew, and Brazil nut. The lifetime self-reported prevalence was 0.8% (95% CI0.5–1.1) for hazelnut and 0.4% (0.2–0.9) for walnut. The point self-reported prevalence was 4.0% (2.9–5.2) for hazelnut, 3.4% (2.0–4.9) for Brazil nut, 2.0% (1.1–2.9) for almond, and 1.8% (1.1–2.5) for walnut. Point prevalence of food challenge- confirmed TNA was 0.04% (0.0–0.1) for hazelnut and 0.02% (0.01–0.1) for walnut. Due to paucity of data, we could not identify any meaningful and consistent differences across age groups and European regions.

The nutritional benefits and immunological advantages of consuming nuts and seeds are well-established. However, the link between nuts and seeds consumption and the susceptibility of being overweight or obese among adolescents is not clear. This study aims to explore this relationship in adolescents aged 12-19. Using a weighted multiple logistic regression model, we analysed data of the Food Patterns Equivalents Database and the U.S. National Health and Nutrition Examination Survey (NHANES) from 2003 to 2018. We found a significant association between nuts and seeds consumption and a reduced odds of being overweight or obese in females. Specifically, females who habitually consumed nuts and seeds had lower odds of being overweight or obese (OR = 0.55, 95% CI: 0.32-0.94). Additionally, we found an L-shaped relationship between nuts and seeds consumption and appropriate waist-to-height ratio in males. The findings suggest that nuts and seeds consumption may contribute to healthier physical development in adolescents.
Nguyen, M.Q., Y. Miyake, K. Tanaka, S. Hasuo, Y. Nakamura, H. Okubo, S. Sasaki, M. Arakawa, 2024. Nut consumption during pregnancy is associated with decreased risk of peer problems in 5-year-old Japanese children. J Pediatr Gastroenterol Nutr. 78(4):927-935.
Objectives: Nuts are nutrient-dense foods rich in unsaturated fatty acids, protein, dietary fiber, vitamins, and minerals. The present prebirth cohort study examined the association between maternal nut intake during pregnancy and the risk of childhood behavioral problems in 5-year-old Japanese children. Methods: Study subjects were 1199 mother-child pairs. Dietary intake was assessed using a diet history questionnaire. Emotional problems, conduct problems, hyperactivity problems, peer problems, and low prosocial behavior were assessed using the parent-reported version of the Strengths and Difficulties Questionnaire. Adjustments were made for a priori-selected nondietary confounders and potentially related dietary factors. Results: Compared with mothers who had not eaten nuts during pregnancy, mothers who had eaten nuts had a significantly reduced risk of peer problems in children; the adjusted odds ratio was 0.64 (95% confidence interval: 0.42-0.97). There were no measurable associations between maternal consumption of nuts during pregnancy and the risk of childhood emotional problems, conduct problems, hyperactivity problems, and low prosocial behavior. Conclusions: Maternal consumption of nuts during pregnancy may be associated with a decreased risk of peer problems in 5-year-old children.
