This study aimed to assess the quality and accuracy of nutrition information about cancer prevention available on the Web. The keywords 'nutrition + diet + cancer + prevention' were submitted to the Google search engine. Out of 400 websites evaluated, 100 met the inclusion and exclusion criteria and were selected as the sample for the assessment of quality and accuracy. Overall, 54% of the studied websites had low quality, 48 and 57% had no author's name or information, respectively, 100% were not updated within 1 month during the study period and 86% did not have the Health on the Net seal. When the websites were assessed for readability using the Flesch Reading Ease test, nearly 44% of the websites were categorised as 'quite difficult'. With regard to accuracy, 91% of the websites did not precisely follow the latest WCRF/AICR 2007 recommendation. The quality scores correlated significantly with the accuracy scores (r = 0.250, p
Development and promotion of dietary guidelines is one of the key activities outlined in the National Plan of Action for Nutrition of Malaysia for the prevention of nutrition-related disorders. The first official Malaysian Dietary Guidelines (MDG) was published in 1999 and was thoroughly reviewed and launched on 25 March 2010. The new MDG 2010 is a compilation of science-based nutrition and physical activity recommendations. These guidelines form the basis of consistent and scientifically sound nutrition messages for the public. There are 14 key messages and 55 recommendations, covering the whole range of food and nutrition issues, from importance of consuming a variety of foods to guidance on specific food groups, messages to encourage physical activities, consuming safe food and beverages and making effective use of nutrition information on food labels. The MDG also has an updated food pyramid. Various efforts have been made to ensure that the revised MDG is disseminated to all stakeholders. The Ministry of Health has organised a series of workshops for nutritionists and other health care professionals, and the food industry. In collaboration with other professional bodies and the private sector, the Nutrition Society of Malaysia has been promoting the dissemination and usage of the MDG to the public through a variety of formats and channels. These include the publication of a series of leaflets, educational press articles, educational booklets, as well as through educational activities for children. It is imperative to monitor the usage and evaluation of these dietary messages.
Kajian berbentuk hirisan lintang ini dijalankan untuk mengkaji hubungan antara keterlibatan aktiviti di kolej kediaman dengan status pemakanan pelajar Universiti Kebangsaan Malaysia (UKM) Kuala Lumpur dan menentukan tabiat makan pelajar serta kebolehdapatan makanan sihat di sekitar mereka. Seramai 106 pelajar tahun dua hingga empat UKM Kuala Lumpur terlibat dalam kajian ini (20.8% lelaki dan 79.2% perempuan). Data pengambilan makanan subjek direkod dengan menggunakan diari makanan tiga hari. Keterlibatan subjek dalam aktiviti kolej dan juga kebolehdapatan makanan sihat ditentukan dengan menggunakan borang soal selidik yang dibentuk khas untuk kajian ini. Berat badan, ketinggian, ukurlilit pinggang, peratus lemak tubuh dan Indeks Jisim Tubuh (IJT) juga diukur. Hasil kajian menunjukkan majoriti daripada subjek (62.3%) terlibat secara aktif dengan aktiviti yang diadakan di kolej kediaman. Daripada peratusan ini, 5.3% daripada subjek lelaki dan 31.9% perempuan adalah kurang berat badan. 68.4% subjek lelaki dan 55.3% perempuan mempunyai berat badan normal. 21% subjek lelaki dan 8.5% perempuan adalah pra obes. Tambahan pula, 5.3% (n = 1) subjek lelaki dan 4.3% (n = 2) daripada subjek perempuan tergolong dalam klasifi kasi IJT obes. Kajian ini mendapati majoriti subjek bersetuju bahawa mudah untuk memperolehi makanan sihat di kampus. Terdapat korelasi positif yang signifi kan di antara pengambilan tenaga (r = 0.352, p < 0.05) dan lemak (r = 0.391, p < 0.05) dengan Indeks Jisim Tubuh (IJT) bagi penglibatan terhadap aktiviti kolej yang kurang daripada tiga jam. Bagi penglibatan terhadap aktiviti kolej yang lebih daripada tiga jam pula, terdapat korelasi positif yang signifi kan di antara pengambilan tenaga (r = 0.678, p < 0.01), lemak (r = 0.550, p < 0.05), karbohidrat (r = 0.685, p < 0.01), protein (r = 0.465, p < 0.05), kalsium (r = 0.357, p < 0.05), ferum (r = 0.500, p < 0.05), vitamin A (r = 0.733, p < 0.01) dan vitamin E (r = 0.582, p < 0.05) dengan IJT. Pencapaian ‘Recommended Nutrient Intake’ (RNI) bagi pengambilan tenaga, kalsium, ribofl avin, vitamin C dan vitamin E adalah lebih tinggi bagi subjek yang terlibat dengan aktiviti kolej kurang daripada tiga jam berbanding dengan subjek yang terlibat dengan aktiviti kolej lebih daripada tiga jam. Kesimpulannya, walaupun ramai subjek yang aktif, masih terdapat dalam kalangan mereka yang mengalami masalah kurang berat badan, lebih berat badan dan obes. Oleh yang demikian, penglibatan dalam aktiviti di kolej kediaman memberi kesan kepada status pemakanan pelajar Universiti Kebangsaan Malaysia.
The data consists of actual generation-side auditing including the distribution of loads, seasonal load profiles, and types of loads as well as an analysis of local development planning of a resort island in the South China Sea. The data has been used to propose an optimal combination of hybrid renewable energy systems that able to mitigate the diesel fuel dependency on the island. The resort island selected is Tioman, as it represents the typical energy requirements of many resort islands in the South China Sea. The data presented are related to the research article "Optimal Combination of Solar, Wind, Micro-Hydro and Diesel Systems based on Actual Seasonal Load Profiles for a Resort Island in the South China Sea" [1].
Food expenses accounted for 66% 54% of the total income in the two plantations. The nutritional value of foods purchased and consumed and the adequacy of nutrient intakes in two plantations was studied. The diets were found to be inadequate in calories, protein, calcium, iron and riboflavin. Carbohydrates provided the bulk of the calories. The significance of the findings are discussed.
Cyclopoid copepod has a potential as live feed that can provide ornamental fish larvae with energy and essential nutrients, and promote their growth and survival, as well as affect their colouration. However, the nutrition, growth and nutritional requirements of this species are poorly understood. This research focuses on comparing the efficacy of enrichment types on copepods towards the growth rate, survival rate and colouration of Pterophyllum scalare larvae. The enrichment of copepods consists of four enrichment procedures (rice bran, palm kernel cake (PKC),Chlorella and yeast). This study was carried out over 50 days and the growth rate, survival rate and colouration (growth rate, survival rate, SGR and colouration) were used to evaluate the responses of P. scalare larvae towards different enrichment methods. Specific growth rates (8.0161 ± 1.4928 %; P = 0.775) and survival rates (66.667 ± 5.337%; P = 0.815) of fish larvae were found to not be significantly different (P = 0.775, P = 0.815; P >0.05). However, the colouration of the fish larvae was affected by the types of enrichment used (P
Monitoring and detecting individual cows' liveweight (LW) and liveweight change (LWC) are important for estimation of nutritional requirements and health management, and could be useful to measure short-term feed intake, water consumption, defecation, and urination. Walk-over weighing (WOW) systems can facilitate measurements of LW for these purposes, providing automated LW recorded at different times of the day. We conducted a field study to (1) quantify the contribution of feed and water intake, as well as urine and feces excretions, to short-term LWC and (2) determine the feasibility of stationary and WOW scales to detect subtle changes in LW as a result of feed and water intake, urination, and defecation. In this experiment, 10 cows walked through a WOW system and then stood individually on a stationary scale collecting weights at 10 and 3.3 Hz, respectively. Cows were offered 4 kg of feed and 10 kg of water on the stationary scale. For each animal, LW before and after eating and drinking was then calculated using different approaches. Liveweight change was calculated as the difference between the initial and final LW before and after eating and drinking for each statistical measure. The weights of feed intake, water consumption, urination, and defecation were measured and used as predictors of LWC. Urine and feces were collected from individual cows while the cow was on the scale, using a container, and weighed separately. The agreement between LWC measured using either stationary or WOW scales was assessed to determine the sensitivity of the scales to detect subtle changes in LW using the coefficient of determination (R2), Lin's concordance correlation coefficient (CCC), and mean bias. The prediction model showed that most of the regression coefficients were not significantly different from +1.0 for feed and water, or -1.0 for urine and feces. The R2 and CCC values demonstrated a satisfactory agreement between calculated and stationary LWC and values ranged from 0.60 to 0.92 and 0.71 to 0.94, respectively. A moderate agreement was achieved between calculated and automated LWC with R2 and Lin's CCC values of 0.45 to 0.63 and 0.60 to 0.74, respectively. Therefore, results demonstrated that new algorithms and data processing methods need to be continuously explored and improved to obtain accurate measurements of LW to measure changes in LW, especially from WOW scales.
Since early 2000, Malaysian food-export industries have recognised the demand for food
compliant with Islamic dietary law (halal), with primary consumer choices based on quality
and safety. The lack of documented monitoring for health hazards and haram substances led
to the withdrawal of certification. The HACCP-based halal quality-assurance standards were
developed as a result, using the HACCP criteria for safety, religious dietary requirement and
quality. Halal critical control points (HlCCP) are identified using HACCP criteria and a question
tree on HALAL processing and storage. This approach harmonizes and unifies halal processing
with the specific food industry via an HACCP–based halal quality-assurance system.
There are numerous challenges in providing nutrition to the mechanically ventilated critically ill ICU patient. Understanding the level of nutritional support and the barriers to enteral feeding interruption in mechanically ventilated patients are important to maximise the nutritional benefits to the critically ill patients. Thus, this study aims to evaluate enteral nutrition delivery and identify the reasons for interruptions in mechanically ventilated Malaysian patients receiving enteral feeding.
The number of older persons in Asia is expected to triple by 2050. Ageing is associated with non-communicable chronic diseases, malnutrition, and geriatric syndromes, which influences the burden on the cost related to healthcare, health outcomes, and the quality of life. Experts in the field of older adult nutrition from Asia, Australia, and Europe were invited to participate in a two-day workshop to review the available data, current policies and programs for the ageing population in different countries of Asia to identify the gaps in knowledge and to develop recommendations for action. In Asia, most of the data pertaining to health status, nutritional status, and nutrient intake of the older persons were mainly obtained by conducting studies in nursing homes or hospitals and small cohort studies. There were limited country-specific data on this population. Moreover, the available data pertaining to different countries were difficult to compare due to differences in the reporting format and reference values used. Although nutrition initiatives and policies were realized and public education was conducted to support the older persons, most of these efforts targeted the general population rather than the older persons population segment. In healthcare management, a higher amount of education is required pertaining to the knowledge of nutritional requirements and appropriate feeding of the older persons to reduce underfeeding and its consequences. The expert group recommended the use of a systematic approach for reviewing data pertaining to different countries, initiatives, and programs to further evaluate the available data to underpin future research.
Study of broodstock maturation diets is important in order to increase the quality of berried females, which indirectly improve the larval quantity in the hatchery production of cultured species. This paper reviewed the studies on the maturation diets for mud crab broodstock, genus Scylla and compared independently to identify their effect on reproductive performance and larval quality. The broodstock is usually caught from the wild and held in the spawning or maturation tank for further use of hatchery seed production. Mud crab broodstock was fed either natural diet, artificial diet or mixed diet. Trash fishes were commonly used as a natural feed for mud crab broodstock; meanwhile artificial diets are from formulated fish meal and various kinds of feed. The results indicated that mud crab broodstock has a high dietary requirement for lipids, fatty acids and protein which are to be used during the maturation and breeding processes. However, the natural diet produce better larval quality compared to the artificial diet. The mixed diet is the better diet which resulted in better reproductive performances such as growth, survival, fecundity and maturation processes. This review also discusses the problems in the previous studies for the potential future research to develop very high quality and cost-effective formulated diet for the enhancement of broodstock and seed production technology. Information from this review can be useful in developing a better quality of crustacean broodstock's diet for commercial hatchery production.
A dietary survey was carried out in 216 children (109 males, 107 females) aged 1-7 years, living in rural villages in Selangor, Malaysia to assess their nutrient intake and to determine the association between nutrient consumption and socio-economic background. All the children studied had inadequate intakes of energy, iron and niacin according to Recommended Daily Intake (RDI). Children aged of 4-9 years showed inadequate intake of calcium, thiamine and riboflavin. However, the intake of protein, vitamin A and ascorbic acid were above the recommended value. The mean percentage requirements of protein, iron and niacin were significantly higher in children from small families compared with children from large families. However the employment status of mothers had a significantly effect on the mean percentage requirements of niacin. The results indicate that education level of the mothers, is strongly associated with the mean percentage nutrient requirements of children and we strongly feel that this is a strategy to be adopted for improvement in nutrition of children.
Problems with assessing the effect of maternal nutrition and lactation performance are presented in relation to a conceptual mathematical ziggurat. Difficulties, variations and flows are to be found in stages of this sequence of "logic" [e.g., assessment of maternal nutrition, volume and composition of breast milk, nutritional satisfactions of the nursling). It is concluded that the various steps in this process of reasoning are subject to much more variation and adaptation than appreciated. Much so-called "faltering" in the second trimester is physiologically normal ("pseudo-faltering").
At the present time, no artificial larval diet is capable of entirely fulfilling the dietary requirements of several larval fish and crustacean species. Zooplankton live food is the basic foundation of fish larviculture, and successful rearing of fish larvae still heavily depends on an adequate supply of nutritious live food. Despite being important, the production protocols of copepods and cladocerans (Moina) are still underdeveloped in hatcheries. Rotifers and Artemia are the most commonly used live foods. However, these live foods are evidently lacking in crucial nutrient constituents. Hence, through nutrient enrichment, live food with the nutritional profile that meets the requirements of fish larvae can be produced. With the aim to maximize the effectiveness of production to optimize profitability, it is important to evaluate and improve culture techniques for the delivery of micro- and macro-nutrients as feed supplements to larvae in aquaculture systems. Bioencapsulation and enrichment are the evolving techniques in aquaculture that are commonly employed to enhance the nutritional quality of live food by integrating nutrients into them, which subsequently improves the growth, survival, and disease resistance of the consuming hosts. This review aims to highlight some of the approaches and methods used to improve the nutritional quality of live food by modifying their nutrient composition, which could have immense promise in the enhancement of aquatic animal health.
Partially hydrolyzed formulas (pHFs) are increasingly used worldwide, both in the prevention of atopic disease in at-risk infants and in the therapeutic management of infants with functional gastrointestinal manifestations. Because prevention is always preferable to treatment, we reviewed the literature aiming to find an answer for the question whether pHF may be recommended for feeding all infants if breast-feeding is not possible. PubMed and Cochrane databases were searched up to December 2014. In addition, to search for data that remained undetected by the searches, we approached authors of relevant articles and major producers of pHFs asking for unpublished data. Because few data were found, nonrandomized, controlled trials and trials in preterm infants were included as well. Overall, only limited data could be found on the efficacy and safety of pHF in healthy term infants. Available data do not indicate that pHFs are potentially harmful for healthy, term infants. With respect to long-term outcomes, particularly referring to immune, metabolic and hormonal effects, data are, however, nonexistent. From a regulatory point of view, pHFs meet the nutrient requirements to be considered as standard formula for term healthy infants. Cost, which is different from country to country, should be considered in the decision-making process. Based on limited available data, the use of pHF in healthy infants is safe with regard to growth. The lack of data, in particular for metabolic consequences and long-term outcomes, is, however, the basis for our recommendation that health authorities should develop and support long-term follow-up studies. Efficacy and long-term safety data are required before a recommendation of this type of formula for all infants can be made.
In the field of human energy expenditure, the measurement of basal metabolic rate (BMR) is an essential element to derive energy requirement estimates for any given population. Besides basic anthropometrics data, this paper reports the generation of predictive equation for basal metabolic rates of healthy Malaysian adult from prospective measurements on 307 male and 349 females aged 18-60 years, using the Douglas bag technique. These new equations based on body-weight reveal that the current FAO/WHO/UNU (1985) predictive equations overestimate BMR of adult Malaysian by an average of 13% in males and 9% in female subjects while differences of between 4-5% were observed when compared to Henry & Rees (1991) equations for tropical people. There is a good reason to believe that the capacity to slow down metabolism amidst the hot and humid climate experience throughout the year as a genuine phenomenon for Malaysians. Similarly, these findings suggest that at equal energy intake recommendation for similar body weight, the lower energy needs of Malaysian could put them at greater risk for developing obesity. These observed deviations must be taken into account in formulating energy requirements of the population.
Introduction: The home environment plays an influential role in affecting dietary and physical activity practices of children. This study aimed to determine the association between the home environment, dietary practice and physical activity among primary school children in Selangor. Methods: This cross-sectional study was conducted in five primary schools selected using multistage stratified sampling. A total of 293 children (32.8% males and 67.2% females) (mean age of 11.0±0.9 years) and their parents (10.7% fathers and 89.3% mothers) completed the study. Dietary practice of the children was assessed using a two-day dietary recall. Energy expenditure and physical activity of the children were assessed using a two-day physical activity recall. Parents of the children completed the Home Environment Survey (HES). Results: The mean energy intake of the children was 1765±416 kcal/day with 75.0% not achieving the Malaysian Recommended Nutrient Intake (RNI) for energy. Almost all children (96.5%) were physically inactive, with a mean energy expenditure of 1269±342 kcal/day. High availability of fruit/vegetable at home was associated with high vegetable intake (r=0.128, p
An assessment of the daily intake of major nutrients among 409 adults (males and females aged between 18-60 years, normal body mass index) residing in four regions in Malaysia was carried out as part of a major study on energy requirement. Subjects from both urban and rural areas completed a 3-day food record during the study. Mean energy intake among the men and women were 9.05 ± 2.21 MJ/day (2163 kcal/day) and 7.19 ± 1.60 MJ/day (1718 kcal/day) respectively, corresponding to 90% of the Malaysian RDA. A mean of 14% of the total energy was derived from protein, 23% from fat and 63% from carbohydrate. Energy intake amongst male subjects in the rural area (8.47 MJ/day, 2024 kcal) was significantly lower than their urban counterparts (9.52 MJ/day, 2275 kcal). There was no difference in mean energy intake in both the urban (7. 19 MJ/day, 1718 kcal) as well as rural women (7.16 MJ/day, 1711 kcal) corresponding to 86% of the RDA. The distribution of nutrients to the total energy intake amongst rural subjects were 13% for protein in both males and females, 65% for carbohydrate in males and 66% in females and 19% for fat in males and 21% for females. In the urban male and female subjects, the distribution of protein, carbohydrate and fat to the total energy intake were 14%, 55% and 29% and 30% respectively. The rural subjects showed a poorer mean intake of vitamins and minerals compared to the urban subjects. The diets of the male subjects in the rural area were deficient, less than two-third RDA in calcium, riboflavin and niacin. Calcium and iron intakes were less than two-third RDA in both the rural as well as the urban women. The rural women also had a poor intake of vitamin A and niacin. Overall, only protein and vitamin C intake met the RDA in most subjects from rural and urban areas.
Athletes are a special group of consumers whose specific diet requirement is important during training and competition to ensure their success. As commercial foodservice establishments are increasing involved in providing foods to this group of consumers on one hand and the lack of research investigating the athletes’ dining satisfaction, especially meeting their diet requirement on the other hand, this study was conducted to investigate the influence of nutritional factors in athletes’ dining satisfaction and the acceptance of various foods provided in an international sporting event. Following a stratified random sampling, 700 athletes were selected from the entire population of 1330 participants. The final usable sample size was 450 (64.3% response rate). Regression analysis revealed that overall service, overall food quality, grooming of server, and nutritional information tag significantly influence the overall dining satisfaction among athletes. In addition, nutritional value, menu variety, fat content, freshness, and taste were found as the most important determinant in almost all food categories. It is intriguing that meeting diet requirement is not a significant factor but nutritional information tag is. Important implications were discussed. Nutrition education is recommended for foodservice operators especially when they are involved in providing food for sporting events. It is advisable that an appointed specialized sport dietitian or nutritionist to a sporting event works together with the foodservice operators to ensure that the menu meets the nutritional requirement of athletes.
