Sarcopenia emerges as a predominant health concern among the older adults, it makes the identification of relational factors crucial. Nut, a universally consumed dietary component, is posited to confer benefits to the musculoskeletal system. This study aimed to elucidate the association between nut consumption and sarcopenia in Chinese older adults. Data concerning nut consumption and sarcopenia were sourced from the 2018 wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). The analysis incorporated 14,281 participants furnishing valid responses. This research employed logistic regression to investigate the association between nut consumption and sarcopenia. A total of 14,181 older adults (mean age = 84.86 ± 11.47 years and 55.08% were female) were included in this study. This study found an inverse association between nut consumption and sarcopenia in Chinese older adults, with higher nut consumption associated with a lower prevalence of sarcopenia, even after controlling for confounders. Compared with the nut consumption group of occasionally/rarely or never, the adjusted ORs of sarcopenia for at least once per month, at least once per week, and almost every day were 0.78 (95% CI: 0.66, 0.91), 0.81 (95% CI: 0.69, 0.95), and 0.62 (95% CI: 0.51, 0.77), respectively. Moreover, the result also displayed there is a significant interaction of nut consumption with gender (P-value = 0.016). This study identified an inverse association between nut consumption and sarcopenia. Introducing nut into the dietary regimen might present an accessible approach to bolster musculoskeletal health among the older adults.
Sandhu, A.K., I. Edirisinghe, B. Burton-Freeman, 2025. Pecans and human health: distinctive benefits of an American nut. Nutrients. 17, 3686. https://doi.org/10.3390/nu17233686
Pecans are a tree nut native to America with a rich content of unsaturated fatty acids, minerals, fiber, and a diverse array of bioactive components, including polyphenols, tocopherols, and phytosterols. This review summarizes variations in the phenolic composition of pecans from various parts of the world based on cultivar, maturity stage, postharvest storage, and processing. Additionally, the review delves into the bio-accessibility and bioavailability of bioactive components from pecans and their potential influence on diet quality, body weight, satiety, cardiometabolic, brain and gut health. Data from human clinical trials suggest that replacing foods/snacks with pecans improves overall diet quality and lipid profiles. However, inconsistent effects are observed on vascular function, glycemia, and inflammation. Body weight changes after pecan intake are reported as neutral, with promising results on satiety peptides and appetite regulation. Cognition and gut health are emerging areas of research with very limited data from both human and preclinical models, warranting further investigation. Overall, the current literature supports the cardiometabolic benefits of pecans within healthy dietary patterns. Future research should focus on well-controlled studies targeting at-risk populations to understand mechanistic endpoints such as metabolomics, microbiome, and vascular function assessments to substantiate the role of pecans in dietary guidance.
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.
Gletsu-Miller, N., Henschel, B., Tekwe, C.D. and Thiagarajah, K., 2024. A cross-sectional study on the association of walnut consumption with obesity and relative fat mass among United States adolescents and young adults in NHANES (2003–2020). Curr Dev in Nutr. 8(8), p.104407. https://doi.org/10.1016/j.cdnut.2024.104407
Background: Walnuts contain nutrients and phytochemicals that can promote metabolic health. However, the high energy content of walnuts along with other nuts raises the concern that consuming nuts promotes obesity. Objectives: We sought to investigate the associations between consumption of walnuts as well as other nuts and measures of obesity in adolescents and young adults. Methods: This study included 8874 adolescents (12–19 y) and 10,323 young adults (20–39 y) from 8 waves of National Health and Nutrition Examination Survey data (2003–2020). The associations of consumption of 1) walnuts only (WO); 2) walnuts with other nuts (WON); 3) other nuts (ON); and 4) no nuts (NN) with obesity status and relative fat mass (RFM) were assessed using logistic and linear regressions stratified by age group and sex. Sample weights were used in all statistical analyses. Results: The mean daily intake of walnuts was not different between the 2 walnut consumption groups within each age group (adolescents: 2.18 [standard error (SE) 0.14] g; P = 0.917; young adults: 4.23 [0.37] g; P = 0.682). The WON group had the lowest prevalence of obesity (adolescents: 8.3%; young adults: 21.1%) while the NN group had the highest prevalence (adolescents: 24.1%; young adults: 35.4%). The models indicated lower odds of obesity in adolescent girls (odds ratio [OR]: 0.27; P < 0.05) and young adult women (OR: 0.58; P < 0.05) who consumed WON than in those who consumed NN. In both young women and girls, RFM was significantly lower in the WON and ON groups than the NN group (P < 0.001). In young men, WON consumption was also associated with a lower RFM (OR: −1.24; 95% confidence interval: −2.21, −0.28) compared with NN consumption. Conclusions: For adolescent girls and young women, dietary intake of walnuts combined with other nuts has the strongest inverse association with measures of obesity.
