Increased prevalence of metabolic syndrome (MetS) has become a global major public health problem. Chronic low-grade inflammation associated with diet was found to play an import role in the development of MetS, although further studies are needed. The main purpose of this study was to explore the association between the dietary inflammatory index (DII), C-reactive protein (CRP) as a sign of inflammation status, and MetS. A total of 1712 participants from eight cities in China were included. Sociodemographic and health-related information was collected by a self-administrated questionnaire. Anthropometric information and fasting blood samples were collected for identification of MetS. DII scores were computed based on one time 24-h dietary recall. No significant association between MetS and DII was observed except for the blood pressure component of MetS (OR T3 versus T1 = 1.40; 95% CI: 1.03 to 1.89). A significant increased prevalence for MetS was observed for higher CRP (OR = 1.66; 95% CI: 1.26 to 2.18), as well as four out of five of MetS components. In stratified analyses by sex, the associations between DII/CRP and MetS among women, but not men, are comparable to the whole sample. In addition, Both the 2nd and 3rd tertile of the DII had a higher CRP level (β-Coefficients T2 versus T1 = 0.086, 95% CI: 0.004 to 0.167; β-Coefficients T3 versus T1 = 0.145, 95% CI: 0.045 to 0.245) among subjects with MetS. Participants with higher DII scores reported a higher degree of “Shanghuo” (p = 0.007), which is a traditional concept characterized by “redness, swelling, fever and pain” in Chinese Medicine. This study suggested a close association between CRP and MetS, while the association between the DII and MetS was limited. DII was only specifically associated with CRP at a higher level among participants with MetS. [ABSTRACT FROM AUTHOR]

The recommended amino acid requirements of the infant are based on the amino acid composition of mature human breast milk. The amino acid composition of breast milk is usually determined following either acid or alkaline (for tryptophan) hydrolysis. For accuracy, however, the known effect of hydrolysis time on amino acid composition should be accounted for. Also, ideally the amino acid composition of breast milk should be given in units of digested (assumed to be absorbed) amino acids. A review of the literature is presented which gives mean total amino acid concentrations in mature human milk ( n  = 26 studies), mean hydrolysis correction factors ( n  = 3 studies) and mean true ileal amino acid digestibility coefficients ( n  = 3 studies, suckling piglet). There were differences between the estimates of amino acid concentration corrected for hydrolysis time and digestibility, and current FAO (2013) recommendations that were not corrected for these factors. The values based on the published literature up until 2023 (mg/g true protein) corrected for hydrolysis time and digestibility gave higher values (more than 16% higher) for leucine, lysine and threonine, and considerably higher values (greater than 30%) for histidine and tryptophan.

Long-chain polyunsaturated fatty acids (LC-PUFAs), arachidonic acid (ARA, 20:4n-6) and docosahexaenoic acid (DHA, 22:6n-3) are essential in the development of infants. ARA and DHA from breast milk or infant formula are the main sources of access for infants to meet their physiological and metabolic needs. The ratio of ARA to DHA in breast milk varies among regions and different lactation stages. Different ratios of ARA and DHA mainly from algal oil, animal fat, fish oil, and microbial oil, are added to infant formula in different regions and infant age ranges. Supplementing with appropriate ratios of ARA and DHA during infancy promotes brain, neural, visual, and other development aspects. In this review, we first introduced the current intake status of ARA and DHA in different locations, lactation stages, and age ranges in breast milk and infant formula. Finally, we discussed the effect of different ratios of ARA and DHA on infant development. This review provided a comprehensive research basis for the nutritional research of infants who consume different ratios of ARA and DHA.

Objective: To assess the differences between anthropometric indices in predicting dyslipidemia in Chinese urban adult population and find optimal cut-off points., Methods: A total of 1615 subjects with information on key variables were enrolled by multistage stratified sampling process from March to July in 2016. Information on sociodemographic characteristics( age, gender, nationality, education and income), and health and disease history of subjects was collected. Height, weight, waist circumference( WC), hip circumference, body fat percentage( % Fat), and fasting lipid profiles were measured for each participant. The receiver operating characteristic( ROC) curve was used to compare the efficacy of the various anthropometric indices to discriminate those with and without dyslipidemia., Results: Waist-to-height ratio( WHtR) had the largest area under the ROC curve( AUC) for dyslipidemia in women( 0. 744). There weresignificant differences between AUC of WHtR and that of WC( P = 0. 008), body mass index( BMI, P = 0. 004), waist-to-hip ratio( WHR, P = 0. 005), and % Fat( P <0. 001) in pairwise comparisons. Cut-off point for WHtR was 0. 50 for dyslipidemia in urban adult women. Although the AUC for BMI was the highest for dyslipidemia in men, it did not differ significantly from other indices( P all > 0. 05). Cut-off point for BMI was24. 1 kg/m~2 for dyslipidemia in urban adult men., Conclusion: WHtR and BMI might be optimal indices for dyslipidemia for Chinese urban adult women and men, respectively. Regional and sexual differences should be considered when choosing proper indices.
