    Atherosclerosis, the cholesterol deposition in and around cells of the intimal layer of the aorta, has been recognized as one of the main causative factors for cardiovascular diseases. Intensive research has been carried out throughout the world but the precise atherogenesis has yet to be fully understood, though hypercholesterolaemia is considered to be the prime risk factor. The aim of the study was to evaluate the effect of high cholesterol diet consumption on the formation of atherosclerosis in vivo. Three groups of adultWhite New Zealand male rabbits (six animals per group) were used in this study. Except for one group which acted as a control (K), the other two groups were given 1% and 2% high cholesterol diet respectively for 10 weeks. At the end of the experiment, blood samples were taken from the marginal ear vein for plasma cholesterol estimation. The animals were sacrificed and the aorta was excised for histomorphometric analysis. The result shows that despite no significant differences in plasma cholesterol levels being observed between the groups treated with 1% and 2% cholesterol, high cholesterol consumption was able to induce hypercholesterolaemia significantly (p

    The antioxidant and anti-proliferative activity of the aqueous crude extract of Tinospora crispa stem was investigated. The proximate composition of its stem and leaves was determined. Proximate analysis revealed that T. crispa contains - protein: leaves = 4.7%, stem = 1.2%; fat: leaves = 1.5%, stem = 0.43%; carbohydrate: leaves = 11.8%, stem = 19.4%; ash: leaves = 2.7%, stem = 1.1%; moisture: leaves = 79.3%, stem = 77.9%; fibre: leaves = 1.59%, stem = 0.65%; and energy: leaves = 1.59%, stem = 0.65%. The antioxidant activity of the extract prepared at various temperatures and incubation time was evaluated to determine the optimum extraction procedure. Based on DPPH and TBA tests, the preparation of the extract at 60oC for 6 hours was established as the best possible method as it demonstrated the highest inhibition percentage. The extract was tested against brine shrimp to evaluate its toxicity and no significant toxicity was recorded since the IC50 value was more than 1000 μg/ml. The extract produced moderate anti-proliferative activity on selected human cancer cell lines (IC50 MCF-7: 107 μg/ml, HeLa: 165 μg/ml, Caov-3: 100 μg/ml, and HepG2: 165 μg/ml). The findings from this study suggest that T. crispa has the potential to be a source of natural antioxidants and nutrients, besides having a moderate anti-proliferative effect on selected human cancer cell lines.

    Introduction: Malnutrition is associated with poorer outcomes following treatment for colorectal cancer (CRC). This study evaluates the relationship between nutritional status using scored Patient Generated-Subjective Global Assessment (PG-SGA) with the validated European Organisation for Research and Treatment of Cancer questionnaire (EORTC-QLQ C30) which consists of five functional scales, three symptoms scales and one item of global health/quality of life (QOL).
    Methods: A total of 42 CRC patients at oncology outpatient clinics from two hospitals in Malaysia participated in the study from March 2011 to March 2012. The participants were classified as either well-nourished (PG-SGA A) or malnourished (PG-SGA B and C).
    Results: The majority of patients were Chinese, male, with a mean age of 57.1 ± 9.8 years and had been diagnosed with stage 2 CRC. Well-nourished patients had statistically significantly better QOL scores on symptom scales: fatigue (p<0.001), nausea and vomiting (p<0.05), and pain (p<0.001) compared to malnourished patients. PG-SGA was strongly correlated with the main domains of the QOL: global health status (r = -0.395, p<0.05), fatigue (r = 0.816, p<0.001), nausea and vomiting (r = 0.730, p<0.001) and pain (r= 0.629, p<0.001). The better the nutritional status (lower total mean score of PG-SGA), the higher the QOL (high mean score of global health status).
    Conclusion: The scored PG-SGA is suitable for use as a nutrition assessment tool to identify malnutrition and it is associated
    with QOL among this population.

    Malnutrition is common among patients with cancer and it is also associated with their negative health outcomes. Generally, cancer patients undergoing chemotherapy have a high risk of malnutrition, secondary to both the disease and the treatment. It is important that patients maintain a good nutritional status to improve the effects, and minimise the side effects of cancer treatment. A good nutritional status should be maintained for patients through nutritional intervention during cancer treatment. There appears to be no published studies on the effects of intense dietary counselling versus usual dietary care on the nutritional status of colorectal cancer (CRC) patients undergoing chemotherapy alone. Furthermore, there have been no randomised controlled trials (RC1) undertaken in Malaysia, where CRC is increasing. It is therefore important to undertake a RCT of a dietary and lifestyle counselling intervention of CRC outpatients undergoing chemotherapy.
    Methods: The intervention study was an open (masking not used), prospective, and Rcr to examine the effects of intensive individualised dietary and lifestyle counselling on dietary intake and nutritional status in CRC patients undergoing chemotherapy. It was designed as an 8-week program of intensive, individualised dietary and lifestyle counselling followed up with another 8-week post-intervention period without dietary and lifestyle counselling, and compared to a control arm given the usual care. A total of forty-two participants took part in this study and were randomised into two groups, namely, the intervention group (IG) (n=22) and the control group(CG) (n=20) at Kuala Lumpur Hospital and SelayangHospital, Malaysia.
    Results: In this study, 67% of CRC patients were malnourished at baseline. In the IQ the prevalence of malnutrition dropped from 72.7% at baseline to 27.3% eight weeks after the intervention. This repesents a large, and clinically meaningful shift. In the CG, the prevalence of malnutrition, or at risk of malnutrition, was still at 75% at the end of the sixteen weeks.
    Conclusion: Intensive, individualised dietary and lifestyle counselling resulted in improved nutritional status in patients with CRC undergoing chemotherapy.

    A cross-sectional study was carried out to evaluate the nutritional status of 51 subjects with leukemia aged 4 to 12 years from the Haematology and Oncology Paediatric Ward, Universiti Kebangsaan Malaysia Medical Centre (PPUKM) and the Paediatric Institute of Kuala Lumpur. Nutritional status was assessed using anthropometric measurements, biochemical and haematological parameters. Subjects comprised 32 (62.7%) males and 19 (27.3%) females. Most of the subjects (41.2%) were in the age group of 4 to 6 years. More than half of the children were Malays (70.6%) followed by Indians (15.7%) and Chinese (13.7%). The subjects were diagnosed as acute lymphoblastic leukemia (ALL) (84.3%) followed by acute myelogenous leukemia (AML) (13.7%) and chronic myelogenous leukemia (CML) (2.0%) respectively. Most of the children were in remission status (54.9%). Underweight (

    Meal and snack patterns are associated with energy and nutrient intakes and consequently health and nutritional status. The aim of this paper is to describe the percentage of daily energy intake from meals and afternoon snack among Malaysian adults. The study included a representative sample of adults aged 18-59 years (n=7349) from a nationwide Food Consumption Survey conducted by the Ministry of Health. Information on dietary intake was obtained using a one day 24-hour diet recall (24-HDR). Dietary data on 6886 adults were analysed using Nutritionist ProTM and statistical analysis was carried out using the SPSS 13.0. The median percentage of daily energy intake is reported only for adults consuming meals and afternoon tea and by socio-demographic characteristics as well as body mass index (BMI) status. More than 80% of Malaysian adults consumed morning meals, lunch and dinner and 54% reported having afternoon tea. The median percentage of energy intake from morning meals, lunch, dinner and afternoon tea was 29.9%, 30.5%, 32.4% and 17%, respectively. There were variations in the median percentage of energy from meals and snacks according to the socio-demographic variables and BMI status. It is important to understand the eating patterns of Malaysians as the information can assist in efforts to address obesity and diet-related chronic diseases among adults.

    Stress is a common phenomenon. Every individual experiences it. There are many ways of combating stress. Stress is necessary for preparation against challenging situations and danger. It is necessary to have stress before a test so that we are prepared. For instance, stress actually motivates students to prepare for examination but excessive stress can lead to poor performance. This study evaluates the effect of a commercial essence of chicken (CEC) on the various parameters related to stress and cognition of human volunteers. CEC is produced by a hot-water extraction process from chicken meat under high pressure condition. It contains concentrated amounts of proteins, amino acids and peptides such as carnosine compared to homemade traditional chicken soup. Due to the unique extraction process, it has been postulated that readily absorbed amino acids and bioactive peptides are present in CEC. In this experiment, we evaluated the effect of CEC in comparison with a placebo and carageenan on a group of stressed medical students before their examinations. Students were divided into three groups at random and given either CEC, placebo or a carageenan drink daily for two weeks. Before and after the two weeks, the students were given a series of tests to assess their mental and physical well-being as well as attention and memory. The tests were the general health questionnaire (GHQ), SF36, digit span, construction of figures, 3-min memory test, comprehension and mental arithmetic. The students who ingested essence of chicken fared significantly better than the other two groups of students. The ability of essence of chicken to control anxiety by distraction and promoting attention and memory is discussed.

    Dental caries are attributed to various factors including diet. The present crosssectional study determined the frequency of sugary food and drink consumption and defined its relationship to dental caries among preschool children. A total of 50 preschoolers (aged 5-6 years) in three kindergartens of the Department of Community Development (KEMAS) in Titiwangsa, Kuala Lumpur participated in this study. A set of structured questionnaires was used to assess the frequency of sugary food and drink consumption. Dental check ups were performed by a dentist. The dft index (decayed, filled teeth) was used to describe incidence of caries in subjects. Results showed that 62% of the subjects had dental caries. with the mean dft score being 3.72. The frequency of sugary food consumption by the majority of subjects was 2 times a day, while the frequency of sugary drink consumption was more than 3 times a day. There was no significant relationship between frequency of sugary food and drink consumption with incidence of caries. Subjects with high dft scores were more likely to report dental pain. The prevalence of dental caries in preschoolers in this study was high, indicating a need for effective dental health promotion to improve dental health status of this age group.

    The objective of the present experiments are to determine if sheep could safely consume high amount of PKC in their diets and if sheep's consumption of PKC require a chelating agent to tie up the high copper level in PKC to protect it against toxicity. Two experiments were carried out. Experiment 1, with four treatment groups of animals, using from 30 to 100% PKC, mixed with other feed ingredients except minerals. Mineral mixtures were separately mixed with Sodium Molybdate, acting as the chelating agent, and the mineral was offered in separate feed troughs ad.libitum, in the pens for each animal group. Although all groups gave high ADG, the animals in the 100% group had high copper in their blood, which were above4 the normal physiological level at the end of the experimental duration of three months. Three animals from this group died and their liver copper contents were very high. The groups fed up to 72% PKC in their ration did not show any significant elevation of copper or toxicity. Sheep fed similar proportions of ingredients in experiment 2, but with Molybdate incorporated together into all the four similar rations as in experiment 1, did not show any signs of toxicity or elevated blood copper. The animals in all groups produced high ADG. The experiment proved that sheep can take up to 100% PKC in their diet, but a chelating agent must be incorporated into the feed to ensure its sufficient uptake to protect it against toxicity. Giving Molybdate separately from the feed would not ensure sufficient intake of the chelating agent voluntarily. This would result in copper toxicity in the animals.

    Hypertension and obesity are established and independent risk factors for cardiovascular diseases. There are important inter-relationships between these two factors that may explain the aetiology of coronary heart disease. To determine the prevalence of hypertension and obesity in a rural community setting in Malaysia, and to identify their associated factors, a cross-sectional study was conducted among residents aged 15 years and above in Mukim Dengkil, Selangor from June to October 1999. Sample size was 570, giving a response rate of 86.7%. Prevalence of hypertension was 26.8%, with the highest prevalence among those aged 60 years and above (57.3%), and 50 to 59 years old (53.3%). Factors found to be significantly associated with hypertension were male (χ²=4.71, df=1, p<0.05) and age (t=10.7, df=568, p<0.01). Prevalence of obesity was 11.4%, with the highest prevalence among those aged 40 to 49 years (22.7%) and 30 to 39 years (14.4%). The factors associated with obesity were age (p<0.01), female (χ²=12.45, df=1, p<0.05) and ethnicity (Fisher's Exact probability, p<0.05) with Chinese and Malays having a higher prevalence compared to other ethnic groups. However, there was no significant association between hypertension and obesity (OR=1.14, 95% CI=0.65, 2.02). The prevalence of hypertension and obesity in this study is high. There is a need for prevention programs for these risk factors in rural communities in Malaysia.

    Excess dietary fat intake is associated with many chronic diseases. This cross-sectional study determines the differences in nutritional status and diet-related psychosocial factors by accuracy levels of dietary fat intake perceptions among adults. A total of 202 Universiti Putra Malaysia staff (20-55 years old) volunteered to participate in the study. Dietary fat accuracy levels (under-estimate, accurate and over-estimate) were determined by assessing actual fat intake through 24-hour diet recall and self-rated fat intake. Diet-related psychosocial factors assessed were perceived risks, intention to change, outcome expectancies and perceived barriers. About half (49.5%) of the respondents were classified as accurate estimators, while 35.6% and 14.9% were under-estimators and over-estimators, respectively. Dietary fat intake differed significantly between the dietary fat accuracy groups with under-estimators having the highest amount of dietary fat intake (F=17.10; p<0.001) and percentage of fat calories (F=103.99 + 0.533%, p<0.001). Over-estimators had the highest mean BMI (F=3.11, p<0.05) compared to other groups. Among the fat accuracy groups, under-estimators reported the least barriers to eating low fat foods (F= 3.671, p<0.05). There were no significant differences in waist circumference, energy intake, perceived disease risks, intention to change and outcome expectancies among the dietary fat accuracy groups. These findings suggest that inaccurate perceptions of dietary fat intake should not be overlooked as one of the cognitive barriers to dietary change and factors that influence nutritional status among adults.

    Chemical preservatives have been used in the food industry for many years. However, with increased health concerns, consumers prefer additive-free products or food preservatives based on natural products. This study evaluated antimicrobial activities of extracts from Emilia sonchifolia L. (Common name: lilac tassel flower), Tridax procumbens L. (Common name: tridax daisy) and Vernonia cinerea L. (Common name: Sahadevi), belonging to the Asteracea family, to explore their potential for use against general food spoilage and human pathogens so that new food preservatives may be developed. Three methanol extracts of these plants were tested in vitro against 20 bacterial species, 3 yeast species, and 12 filamentous fungi by the agar diffusion and broth dilution methods. The V. cinerea extract was found to be most effective against all of the tested organisms and the methanol fraction showed the most significant (p < 0.05) antimicrobial
    activity among all the soluble fractions tested. The minimum inhibitory concentrations (MICs) of extracts determined by the broth dilution method ranged from 1.56 to 100.00mg/mL. The MIC of methanol fraction was the lowest in comparison to the other four extracts. The study findings indicate that bioactive natural products from these plants may be isolated for further testing as leads in the development of new pharmaceuticals in food preservation as well as natural plant-based medicine.

    Pleurotus ostreatus better known as oyster mushroom is widely cultivated and consumed as food in Malaysia. The present study aims to assess the antioxidative potential and total phenolic content of P. ostreatus aqueous extract. The antioxidant activities were evaluated against DPPH and ABTS radical-scavenging activity, ferric-reducing antioxidant power (FRAP) and β-carotene-linoleate bleaching assay, and the Folin-Ciocalteu method for total phenolic content (TPC). The DPPH and ABTS radical-scavenging activity was found to be 63.20% and 87.29% respectively; antioxidant activity using FRAP at 1.45 mM FE/100g and β-carotenelinoleate bleaching assay was 83.51%, while the TPC was found to be 798.55 mg GAE/100g. These antioxidant activities were compared to synthetic antioxidant, BHA and ascorbic acid. Ascorbic acid showed highest scavenging effects on DPPH and ABTS radical, followed by P. ostreatus and BHA (at maximum safety limit). The ferric reducing power of P. ostreatus was significantly higher than BHA and ascorbic acid. The antioxidant activity as assessed in β-carotene-linoleate bleaching assay was found to be higher in BHA compared to P. ostreatus. The aqueous extract of P. ostreatus was found to respond differently in antioxidant assays. The antioxidative activity of the aqueous extract of P. ostreatus correlated with its total phenolic content. Generally, the antioxidant activities of P. ostreatus' aqueous extract are comparable to that of BHA and ascorbic acid to a certain extent.

    Introduction: There is a lack of information on bone health status of premenopausal women in Malaysia. This study investigated the bone health status of premenopausal women and its associations with anthropometric, dietary and physical activity. Methods: Bone mineral density (BMD) was measured using dual X-ray absorptiometry (DEXA) at the lumbar spine, femoral neck, total hip and total body. Serum osteocalcin, parathyroid hormone (PTH), beta-crosslaps were also determined. Results: A total of 73 Chinese premenopausal women were recruited in the study with a mean age of 39.3 ± 5.0 years. Average BMI, body fat percentage and lean body mass were 22.2 ± 3.4 kg/m2, 33.9 ± 4.6% and 34.5 ± 4.4 kg, respectively. Mean BMD at the spine, total hip, femoral neck, and total body were 1.025 ± 0.118 g/cm2, 0.876 ± 0.109 g/cm2, 0.739 ± 0.110 g/cm2, and 1.061 ± 0.755 g/cm2, respectively. Their serum beta-crosslaps and PTH were within normal range, but serum osteocalcin (8.5 ± 4.2 ng/ ml) was low. On average, calorie intake (1506 ± 427 kcal/ day) was below the Malaysian Recommended Nutrient Intake (RNI) while their calcium intake achieved only 67% of RNI. Their mean metabolic equivalent score (MET) was 771.4 ± 926.1 min/week. Body weight and related indices (BMI, lean mass, fat mass) were significantly positively correlated with BMD at all skeletal sites. Conclusion: The study revealed that Chinese premenopausal women in the Klang Valley have low calcium intake and low level of physical activity.

    As Malaysia is moving towards a rapidly developing economy, its elderly population is also expected to increase not only in numbers and proportion but also in their life expectancies. This demographic shift from a relatively young population to one that includes an increasing number of old and very old age group presents a real challenge to nutritionists and health professionals. The challenge is to maintain a healthy and vigorous elderly population who can lead fulfilling and independent lives. Health promotion and disease prevention efforts, including nutrition education, targeted towards this group can contribute important elements in meeting the challenge. The objective of the study was to assess the nutrition education needs of a sample of elderly Chinese in an urban area. The sample consisted of 34 males and 36 females, whose age ranged from 55 to 86 years. They were generally affluent and well-educated with a mean income of RM101 1.86 and 8.0 years of formal education. A self-administered questionnaire which requires 20 to 30 minutes to complete was used to collect the information. The results of the nutrition knowledge assessment indicated that the typical respondent correctly identified 16 of the 22 nutrition knowledge statements. A majority (91.4%) of the respondents recognized the fact that tomato, dark green leafy vegetables, and orange juice are good sources of vitamin C, while the statement on vitamin supplementation was correctly answered by only 15.7% of the respondents. The mean nutrition knowledge score was 26.14 with a range of between 18 and 36. The t-test indicated a significant difference (t=3.63, p_0.05) between males and females in their nutrition knowledge scores, with the males having higher mean scores. Although only 8.6% of the respondents reported they had participated before in a nutrition education programme, a majority of them believed that nutrition education can improve the nutritional and health status of the elderly. A majority (80%) of the respondents mentioned newspaper articles as their source of nutrition information, while only 8.6% indicated the dietitian as their source of information. However, the doctor was identified as a more creditable and reliable source of information by a majority.

    A seminar titled "Sugar Substitutes: Understanding the Basics, Global Regulatory Approvals, Safety Assessment Protocols and Benefits" organised by the Nutrition Society of Malaysia was held on 1.5th Apri12015 for nutritionists and other health care professionals, to review and discuss the latest evidence on safety and efficacy of sugar substitutes. Highlights from lectures by local and international speakers about this topical subject are presented in this report. Sugar substitutes have been extensively evaluated for decades and regulatory agencies world-wide continue to review and confirm their safety. Furthermore, the effects of sugar substitutes on human health continue to be the subject of research studies. Many studies have shown that replacement of sugar with sugar substitutes may help in weight management, glucose control for people with diabetes, and in the prevention of tooth decay. It is important for health professionals to discern whether the available evidence is based on good science and adequate protocols in order to guide consumers with the responsible use of sugar substitutes following national and international dietary guidelines. The use of sugar substitutes for certain health outcomes was discussed, specifically in regard to appetite, energy balance, body weight and other cardio-metabolic risk factors. Overall, the seminar provided an understanding of the different types of commercially available sugar substitutes, their use in a range of food and beverages, and calorie contribution to the diet. The seminar also covered the approvals of different sugar substitutes and the protocols for assessing the safety of these sugar substitutes, especially in the case of children and pregnant women.

    Among the chemicals, pesticides which are mainly used in agriculture pose major health problems to human beings. Indiscriminate use of pesticides belonging to the class organophosphate, organochlorine, carbomate, and pyrethroid leads to various health problems affecting the nervous, endocrine, reproductive and immune systems. The toxicity of pesticide in human beings is influenced by various factors such as age, gender and health status of the individual in addition to the intensity and frequency of pesticide used. Comparatively, children are at greater risk than the adults. The human detoxification system plays a vital role in reducing the harmful effects of the pesticides. However, when the toxic level is increased beyond the capacity of the detoxification system, health condition deteriorates. Human diet plays a crucial role in maintaining the overall health of a person. Vitamins such as Vitamin C and E are effective in preventing DNA damage because of their antioxidant properties. Intake of fruits and vegetables improves the antioxidants level in the blood. Phenolic substances present in certain spices possess potent anticarcinogenic activities. Organic farming may be a viable solution to reduce the toxic effects of chemicals.

    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
