One portion size of foods frequently consumed by Korean adults

This study aimed to define a one portion size of food items frequently consumed for convenient use by Koreans in food selection, diet planning, and nutritional evaluation. We analyzed using the original data on 5,436 persons (60.87%) aged 20 ~ 64 years among 8,930 persons to whom NHANES 2005 and selected food items consumed by the intake frequency of 30 or higher among the 500 most frequently consumed food items. A total of 374 varieties of food items of regular use were selected. And the portion size of food items was set on the basis of the median (50th percentile) of the portion size for a single intake by a single person was analyzed. In cereals, the portion size of well polished rice was 80 g. In meats, the portion size of Korean beef cattle was 25 g. Among vegetable items, the portion size of Baechukimchi was 40 g. The portion size of the food items of regular use set in this study will be conveniently and effectively used by general consumers in selecting food items for a nutritionally balanced diet. In addition, these will be used as the basic data in setting the serving size in meal planning

Nutritional and Functional Indicators and Their Association With Mortality Among Older Adults With Alzheimer’s Disease

This study investigated how different nutritional and functional status indicators are associated with mortality in patients with Alzheimer’s disease (AD). A prospective cohort study was conducted among 79 community-dwelling older adults with AD. Follow-up was 60 months. Undernutrition status was evaluated by Mini Nutritional Assessment (MNA), body mass index, mid-arm muscle circumference (MAMC), calf circumference, and phase angle. Functional status was assessed by handgrip strength, and usual gait speed. Twenty-two participants died (27.8%). Results show that undernutrition (hazard ratio [HR] 5.69, 95% confidence interval [CI] 2.21-14.61), weight loss (HR 3.82, 95% CI 1.37-10.63), underweight (HR 3.24, 95% CI 1.18-8.82), low MAMC (HR 4.54, 95% CI 1.65-12.48), calf circumference = 31 (HR 4.27, 95% CI 1.63-11.16), low HGS (HR 3.11, 95% CI 1.18-8.17), and low gait speed (HR 4.73, 95% CI 1.68-13.27) were all associated with mortality. In conclusion, a poor nutritional and functional status was associated with a higher risk of mortality, regardless of sex, age, marital status, education, and cognitive function

Provision of a School Snack Is Associated with Vitamin B-12 Status, Linear Growth, and Morbidity in Children from Bogotá, Colombia1–3

In 2004, Bogotá's Secretary of Education (SED) initiated a snack program in public primary schools. A midmorning food ration was provided free of charge to children to supplement 30 and 50% of their daily requirements of energy and iron, respectively. The purpose of this study, an observational investigation of 3202 children ages 5–12 y, was to examine whether the snack program improved children's nutritional and health status. We measured micronutrient levels (plasma ferritin and vitamin B-12, and erythrocyte folate), anthropometry, and reported morbidity during the first semester of the 2006 school year. After adjusting for socioeconomic status and other school interventions, children at schools receiving the snack (n = 1803) had greater increases in plasma vitamin B-12 (42 pmol/L; P < 0.0001) from baseline to 3 mo of follow-up than children at schools not receiving the snack (n = 1399). They also experienced a smaller decrease in height-for-age Z-scores than children who did not receive the snack (P = 0.001). Provision of the SED snack was associated with significantly fewer reported days with morbidity symptoms (e.g. cough with fever, diarrhea with vomiting), 44% fewer doctor visits (P = 0.02), and 23% fewer days of school absenteeism (P = 0.03). The snack was not related to ferritin or folate levels. In conclusion, provision of a school-administered snack was related to improved vitamin B-12 status and linear growth and decreased reported morbidity. Although provision of the snack was not related to BMI changes over a 4-mo period, snack components such as candy and sugar-sweetened beverages should be replaced with healthier options, as the rates of child overweight in Colombia are not negligible

The big picture: Obesity, consumption, and food production

Reducing the percentage of Americans who are either overweight or obese to meet public health objectives may influence agricultural production. The authors' results show that reducing aggregate consumption by 6% to meet public health objectives with no increase in overall physical activity could reduce production of agricultural commodities and reduce net returns to producers by $3.5 billion. However, if consumption is reduced by 2$1.3 billion). Conversely, continuing obesity trends may enhance returns to agricultural production by $1.3 billion annually. Changes in agricultural activities would likely be variable across the landscape. Results indicate that the largest potential changes in agricultural producer net returns (positive or negative) would occur in the Corn Belt and the Lake States. There, crop acreage could fall by as much as 650,000 hectares. &lsqb;EconLit citations: Q130, Q180&rsqb; © 2006 Wiley Periodicals, Inc. Agribusiness 22: 491-503, 2006.
