    ABSTRACT: The aim of this study was to evaluate the effect of dietary protein source and protein level on serum lipids in male rats. Wistar weaning male rats were assigned to four groups (15 rats in each group) according to their original body weight. The effects of two kinds of dietary protein with two different levels, including low cow milk (LM, 9%), high cow milk (HM, 18%), low soybean and egg white (LS, 9%), and high soybean and egg white (HS, 18%) diets, were observed. Each group was provided with one of four diets for 20 weeks. Serum lipids were tested and the ratio of lipid were calculated. Serum TC and HDL-C were the highest and TC/HDL-C was the lowest in HM group; serum TG in HS group was the lowest. The ratio of TG/HDL-C in HS and HM group was lower than LS and LM group. Compared with LM and HM groups, serum LDL-C and LDL-C/HDL-C was lower in LS and HS group. Long-term intake of protein from soybean and egg white, serum TG level may be significantly lower, which may reduce the risk of atherosclerosis. There was a trend of rising serum cholesterol level in rats fed with protein from cow milk for a long time.

    ABSTRACT: To establish a infant and young child feeding index (ICFI) in China to comprehensive evaluate the feeding of children aged 6-24 months. Based on the feed index concept defined by Ruel and Menon in 2002, and according to the feeding principle by WHO and Chinese dietary guidelines for children aged 0-6 years, the feed index for infants and young children was built and the variables were scored. Then using WAZ, HAZ and WHZ, the correlation between ICFI and Z score for children in urban and rural of three provinces (Sichuan, Hebei and Heilongjiang) was evaluated. The ICFI was constituted by 7 parts: continued breast-eeding, bottle-feeding, dietary diversity for the past 24 h, frequency of feeding solids/semisolids for the past 24 h, food frequency for the past 7d, the supplementary time of the formula milk and other foods. The difference of ICFI score between urban and rural group was significant (P < 0.05). In urban, the ICFI score of children aged 6-8 months was lower than that of children aged 9-24 months. In urban, the negatively correlation between ICFI and WAZ WHZ was significant (P < 0.05). In rural, the negatively correlation between ICFI and WHZ was significant (P < 0.05), while the positively correlation between ICFI and HAZ was significant (P < 0.05). ICFI is effective to evaluate the infant feeding in China.

    ABSTRACT: To improve the unhealthy eating behaviors in 3-5 years old children and enrich the nutrition knowledge of their parents by the multi-channel health education intervention, and evaluate the effects of intervention. By random multi-stage cluster sampling, 810 children (3-5 years old) and their parents were selected from Beijing and Shanghai respectively. The period of intervention was 6 months. Questionnaire surveys about children's eating behavior and the knowledge of their parents were conducted before and after the intervention. After the intervention, the proportion of partial eclipse and drinking beverage declined from 44.5% and 70.4% to 35.5% and 31.7% respectively. The proportion of having regular meal time, fixed dining place, eating by oneself, fix quantify diet and concentrating on food elevate from 80.0%, 87.3%, 73.4%, 32.1% and 27.1% to 92.1%, 90.2%, 83.7%, 44.3% and 40.1%. The awareness about nutrition in parents increased and the attitude to the children's eating behaviors improved after the intervention. The intervention has some effects on the improvement of the children' s unhealthy eating behaviors and their parents' nutrition knowledge and attitude.

    ABSTRACT: There are many factors that could affect the requirement of vitamin A including infections, parasites, protein-energy malnutrition, bioconversion efficiency of provitamin A, food matrix and so on. However, the toxicity of vitamin A should also be taken into account when establishing reference values for infants, young and preschool children. Serum and breast-milk retinol concentrations, retinol binding protein concentrations, the relative-dose-response test , the modified-relative-dose-response and the deuterated retinol isotope dilution test are the common tools to assess vitamin A status.
