- Background/Aims: To investigate whether a daily intake of a nutrient-balanced ready meal containing 4 g of oat beta-glucans lowers total cholesterol (T-C) and low-density-lipoprotein cholesterol (LDL-C) in hyperlipidemic subjects and to evaluate its effect on postprandial glucose and insulin concentrations. Methods: A parallel, placebo-controlled trial was carried out in 43 healthy men and women with elevated serum cholesterol levels. During the 3-week run-in period, all subjects consumed daily a ready-meal soup, low in energy and fat and high in fiber but without oat beta-glucans. Subjects were then randomly assigned for the following 5-week intervention period to either continue consumption of the control soup or an equal soup supplemented with beta-glucan. Results: Consumption of the beta-glucan-enriched ready meal decreased T-C (0.22 +/- 0.41 mmol/l) and LDL-C (0.16 +/- 0.36 mmol/l), but the reductions were not significantly lower compared with control. After a meal with beta-glucan soup, neither postprandial glucose nor insulin concentrations were significantly different from those after a control soup. Conclusion: A daily dose of 4 g of oat beta-glucans incorporated into a healthy ready meal did not significantly lower T-C and LDL-C compared with an equal ready meal without beta-glucans. Thus, if a food product fulfils general healthy dietary recommendations it may not necessarily be a candidate for supplementation with beta-glucans. Copyright (c) 2008 S. Karger AG, Basel.

- Aims: To examine changes in anthropometric parametersand lipid profiles over a period of 3.6 years in an Iranian adultpopulation according to body mass index (BMI) groups.Methods: Between 1998 and 2001 (phase 1) and 2002 and2005 (phase 2), 5,618 nondiabetic Iranian adults aged 6 20years were examined. Analysis of covariance was used to delineatetrends in anthropometric parameters as well as totaland low- and high-density lipoprotein cholesterol (TC, LDL-Cand HDL-C, respectively) across BMI groups. Results: AlthoughBMI increased in women, this increase was not significantin obese persons. Among the men, however, a significantincrease in BMI was observed only in lean persons.Waist circumference (WC) increased across all BMI groupsin both sexes. A significant decrease was observed in TC[men: –0.83 mmol/l, 95% confidence interval (CI) –1.27 to–0.40; women: –0.78 mmol/l, CI –0.97 to –0.60] and LDL-C(men: –0.63 mmol/l, CI –1.13 to –0.13; women: –0.51 mmol/l,CI –0.78 to –0.24). A significant decrease in mean HDL-Cwas observed only among men (–0.09 mmol/l, CI –0.13to –0.04), with no difference among BMI groups (p = 0.3).There were no significant decreases in TC/HDL-C and LDLC/HDL-C ratios in men or women. Conclusions: Despite an increase in WC, favorable trends were observed in TC andLDL-C levels. The favorable trend in TC levels was counterbalancedby changes in HDL-C, as reflected by the absence of asignificant decrease in TC/HDL-C or LDL-C/HDL-C

- This project's primary aim is to contribute to the improvement of the quality of life of the elderly. The state of the art in age-related research and technology, to highlight the most promising areas for development, has been documented in an extensive literature report. A research database has been established to map current research activities within the European research area. Through several expert group meetings with representatives from universities, research institutions, organizations concerned with the care of the elderly, and industry, suitable technologies and policies that can improve the diet of the elderly have been identified. A legislation survey relating to aspects of nutrition of the elderly has been carried out. A set of guidelines and recommendations of best practice for use in the health and care industry have been developed. The project's results are disseminated through an enhanced website, technology transfer workshops and a staff training program. Good communication between the partners has been promoted and permanent research links have been forged. The main outputs will lead to better co-ordinated European research: less duplication of effort, more rapid commercialization, increased awareness of the problems faced by the elderly, improved guidelines and recommendations for health care professionals and policymakers.

- Background/Aims: Elderly persons with dysphagia need food that requires little or no chewing, that is easy to swallow and has attractive sensory characteristics. The aim was to investigate how ingredients varied according to experimental designs influence the perceived sensory, chewing and swallowing characteristics of two types of texture-modified model foods. Methods: Meat- and carrot-based, texture-modified model foods were produced. The following parameters were varied: particle size, fat content, starch and egg composition. The samples were studied using sensory analyses, focus group discussions and consumer studies. Results: The design parameters mainly had an impact on sensory texture attributes. The experts in the focus groups selected three products of each type which were regarded as being optimal for older persons. All the products contained a high proportion of egg yolk and a low amount of starch. Older consumers considered all the selected products to be easy to chew and swallow. The differences between older persons in nursing homes compared to those living in their own homes could be linked to health. Conclusions: Optimization of factors influencing food quality through the use of experimental designs in combination with sensory and consumer studies is required in order to meet the needs and demands of older people.
