Male C57BL/6 mice were fed either a 60% of HFD or standard chow with curcumin (2.5g/kg diet) for eight weeks. We observed that curcumin alleviated weight gain, preserved glucose balance, and enhanced liver fat accumulation and lipid profile in mice with obesity induced by a HFD. Curcumin enhanced the adipocyte-derived mesenchymal stem cell (ADMSC) population (Sca-1+CD45-) and expression of phosphorylated checkpoint kinase1 (pCHK1), a DNA repair gene, in adipocytes isolated from adipose tissues of HFD-induced obesity in mice. Moreover, in human preadipocytes, treatment with 10 μM curcumin effectively reduced the mRNA levels of <i>IL6</i> and <i>CCL2</i> in a dose-dependent manner, while treatment with 100 μM H₂O₂ together with curcumin upregulated the levels of pCHK2 and total CHK2 protein and reduced level of γH2AX, a biomarker of DNA damage.

The BEST-D trial, designed to establish the optimum dose of vitamin D3 for future trials, had 305 participants, aged 65 years or older, randomly allocated to 4000 IU vitamin D3 (n=102), 2000 IU vitamin D3 (n=102), or matching placebo (n=101).

Meal frequency was higher with age, and adolescents skipped breakfast more often, and had a later energy distribution than adults. A higher eating frequency and eating breakfast are associated with a higher absolute intake of whole grains, as well as Vitamin D and folate. A higher eating frequency makes it more likely to reach nutrient requirements. However, a higher eating frequency was also associated with a higher intake of free sugars.

This approach intends to strengthen the identification of ultra-processed food products (UPFP) by consumers through the information available on their labels. A cross-sectional study was carried out using data from the list of ingredients and the nutrition facts panel on labels of processed foods and UPFP available in Brazilian supermarkets between April and July 2017, totalling 8,436 food items assessed, of which 84.0% were UPFP. Of the total, 62.7% of the UPFP would have the FoPNL and 65.1%, 37.9% and 12.9% had flavouring, colouring and NSS, respectively. Combining criteria for the FoPNL with any one of the three cosmetic additives analysed, 45.9% of the UPFP were identified, and when considering the presence of the FoPNL, flavouring, colouring or NSS, the identification increased to 89.9%. Results showed that the current FoPNL in Brazil does not facilitate the identification of UPFP.

Yet, decision-making to foster food systems which consider both human and planetary health is growing in complexity. This paper, presented at an IAEA-supported symposium at the 14th European Nutrition Conference of the Federation of European Nutrition Societies (FENS), highlights the potential of stable isotope techniques in generating valuable evidence to help support the development of sustainable food systems. It focuses on three methods: the dual tracer stable isotope technique for measuring protein digestibility, the iron isotope dilution technique for assessing iron absorption, loss and balance, and the deuterium oxide dose-to-mother technique for estimating breast milk intake. The dual tracer isotope method provides a minimally invasive assessment of protein quality from a diverse variety of crops and novel sources, supporting the transition towards environmentally conscious, protein-rich diets. The iron isotope dilution technique can be used to address iron requirements across different population groups and to calculate iron absorption from whole diets or after consuming crops designed to be nutritionally sufficient, thus guiding dietary guidelines and agricultural strategies. Finally, the deuterium oxide dose-to-mother technique provides precise data on breast milk intake, underscoring the role of breastfeeding in sustaining optimal infant nutrition and the conservation of resources. These methods have the ability to generate critical evidence to support policy development and food system innovations that prioritize human health and environmental preservation.</p>","PeriodicalId":9257,"journal":{"name":"British Journal of Nutrition","volume":" ","pages":"1-24"},"PeriodicalIF":3.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144092312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
