Effects of micronized okara dietary fiber on cecal microbiota,serum cholesterol and lipid levels in BALB/c mice

Abstract

Micronized by a dry grinding method (D-ODF) or a wet granulating method (W-ODF), okara dietary fiber (ODF), was fed to BALB/c mice for 28?d. The water holding capacity of D-ODF and W-ODF was significantly enhanced after micronization. W-ODF had a larger swell capacity and a higher content of soluble dietary fiber than crude ODF and D-ODF. After feeding for 28?d, the populations of Escherichia coli and Lactobacilli in the cecum were significantly lower and higher in the W-ODF group than other groups, respectively, while the population of Bifidobacterium increased in all groups. The effect of each diet on the population of E. coli. Lactobacilli and Bifidobacterium was all maintained for a short period of time except that the effectiveness of W-ODF diet on the Bifidobacterium population lasted slightly longer than other diets. At the end of the feeding period, serum total cholesterol (TC) and triglyceride in D-ODF and W-ODF diets were significantly lower and HDL-C/TC ratio was significantly higher than those in crude ODF.     

Commentary—Marasmus in a Newly Rich Urbanized Society

To assess the feasibility of fortifying flour with folic acid as a strategy to prevent neural tube defects in Malaysia, a country where the staple food is rice, we used 24-hour recall to study all cereal flour intake in women of reproductive age. Eighty-eight percent took at least a half portion of cereal flour and 85% took at least one whole portion. Vitamin supplements were taken by 36% but few knew whether the supplement contained folic acid. Cereal flour consumption is frequent and folic acid fortification of flour is feasible. Subgroups of the population not consuming flour need to be identified.     

Nutrition education in the medical school: factors critical to the development of a successful program.

The importance of better nutrition education in the medical school has become more recognized and emphasized in recent years. In an attempt to fulfill increasing needs for teaching programs, unproven approaches have often been used, thereby risking loss of both effectiveness of instruction and student interest. A retrospective evaluation of a decade of teaching experience at the University of Alabama in Birmingham has resulted in a better understanding of what problems may be encountered in the development of a nutrition education program. From this review, two factors appear to be of critical importance to a successful program: relevance of the course material to medical practice and the presence of a strong, positive role model as a physician-nutritionist. Five other factors that need to be considered, but often receive undue priorities, are also discussed.     

Analytical approaches for biomedical elemental analysis.

Several different analytical systems are available for biomedical elemental analysis related to human nutrition. The principle, detection limits, analytical artifacts, and applications are presented for the following analytical systems for elemental analysis classified by sample volume: macro volume systems—flame atomic absorption spectroscopy (FAAS) and inductively coupled plasma (ICP); micro volume systems—electrothermal atomization (graphite furnace) atomic absorption spectroscopy (ETA-AAS) and x-ray fluorescence (XRF); and ultramicro volume systems—electron probe x-ray microanalysis (EPX) and laser microprobe mass analysis (LAMMA).     

Nutritional status of mauritanian children during a drought emergency

Nutritional surveys were conducted in three regions of Mauritania between September and November, 1983, to assess the impact of a severe drought and to determine priorities for relief assistance. Survey sites and children were chosen at random using established Centers for Disease Control survey methodology. A total of 1,498 children between the ages of 6 months and 5 years were weighed, measured and examined for xerophthalmia and scurvy. Information on age, sex, diarrhea, measles immunization, diet and food aid was collected for each child. Levels of acute malnutrition (< 80 % of median weight‐for‐height) ranged from 8.2 to 17.2% in the 3 regions, and both xerophthalmia and scurvy were seen. The children between 1 to 3 years of age had the highest levels of malnutrition. Food aid deliveries were irregular and inadequate in the two regions with the highest rates of malnutrition. Implications for targeting and choice of relief efforts are discussed.     

Agricultural development,diet and nutrition

The geographical distribution of infant mortality rates (IMRs) in the Brazilian State of Rio Grande do Sul follows closely the pattern of land tenure, with high IMRs in districts of large ranches and lower rates in districts of small fanns. A household anthropometric survey of 802 children aged 12 to 35.9 months living in two districts with contrasting IMRs and land tenure patterns revealed that prevalences of protein‐energy malnutrition were consistent with these differentials. The survey showed that children in the district with large ranches were more likely to present with stunting, wasting and underweight than those in the small‐farms district. When the analysis was restricted to rural children, these differentials were even wider — 4‐fold for length for age and 13‐fold for weight for age. Children of labourers were more likely to be malnourished than those of landowners, while children of sharecroppers presented intermediate levels. On the other hand, among children of landowners, there was no association between the area of land owned by the family and malnutrition, or according to whether most of the food consumed was home grown or not.     

Dangers of reducing the range of food choice in developing countries
