Triple burden of malnutrition among Malaysian children aged 6 months to 12 years: Current findings from SEANUTS II Malaysia.

OBJECTIVE: This paper aims to report South East Asian Nutrition Surveys (SEANUTS) II Malaysia data on nutritional status, dietary intake, and nutritional biomarkers of children aged 6 months to 12 years. DESIGN: Cross-sectional survey conducted in 2019-2020. SETTING: Multistage cluster sampling conducted in Central, Northern, Southern, and East Coast regions of Peninsular Malaysia. PARTICIPANTS: 2989 children aged 0.5-12.9 years. RESULTS: Prevalences of stunting, thinness, overweight, and obesity among children aged 0.5-12.9 years were 8.9%, 6.7%, 9.2%, and 8.8%, respectively. Among children below 5 years old, 11.4% were underweight, 13.8% had stunting, and 6.2% wasting. Data on nutritional biomarkers showed a small proportion of children aged 4-12 years had iron (2.9%) and vitamin A deficiencies (3.1%). Prevalence of anaemia was distinctly different between children below 4 years old (40.3%) and those aged 4 years and above (3.0%). One-fourth of children (25.1%) had vitamin D insufficiency, which was twice as prevalent in girls (35.2% vs. boys: 15.6%). The majority of children did not meet the recommended dietary intake for calcium (79.4%) and vitamin D (94.8%). CONCLUSIONS: Data from SEANUTS II Malaysia confirmed that triple burden of malnutrition co-exists among children in Peninsular Malaysia, with higher prevalence of overnutrition than undernutrition. Anaemia is highly prevalent among children below 4 years old, while vitamin D insufficiency is more prevalent among girls. Low intakes of dietary calcium and vitamin D are also of concern. These findings provide policymakers with useful and evidence-based data to formulate strategies that address the nutritional issues of Malaysian children.

Food allergy knowledge, attitude and management among preschool personnel in Malaysia.

BACKGROUND: Children are vulnerable, and they may experience their first serious food allergy reaction at school, where they spend much of their time. The present study aims to determine the level of food allergy knowledge, attitude and management (KAM) among preschool personnel in Klang Valley, Malaysia. METHODS: A cross-sectional study was conducted with 292 personnel working in Klang Valley preschools. The participants completed an online questionnaire asking about sociodemographic information and food allergy KAM. Mann-Whitney U and chi-squared tests were used to compare the KAM level between public and private preschool personnel and examine the association of KAM of food allergy with various sociodemographic factors, respectively. RESULTS: Some 86.3% of the participants demonstrated a low level of food allergy knowledge, 64.7% showed a negative food allergy attitude and 57.9% indicated fair food allergy management. The total mean score for food allergy knowledge was higher (p < 0.01) among the private preschool personnel compared to the public group, although there was no significant difference in attitude (p = 0.244) or practice (p = 0.171). Age group (p < 0.01) and monthly income (p < 0.05) were significantly associated with the level of attitude, whereas no sociodemographic factor was associated with knowledge and management of food allergy. CONCLUSIONS: Most preschool personnel in Klang Valley have a low level of food allergy knowledge, negative attitudes and a fair level of ability to manage food allergy reactions. The findings of the present study may guide future studies to improve the food allergy KAM of preschool personnel and provide a safer environment for children with food allergies.

Germinated brown rice ameliorates obesity in high-fat diet induced obese rats.

BACKGROUND: Germinated brown rice (GBR) is a novel functional food that is high in fiber and bioactive compounds with health-promoting properties. This study aims to evaluate anti-obesity effects of GBR in obese rats fed high-fat diet (HFD). METHODS: Male Sprague-Dawley rats were fed HFD for 8 weeks to induce obesity. The rats were then administrated with GBR where the source of dietary carbohydrate of HFD was replaced by either 25 % GBR, 50 % GBR or 100 % GBR for another 8 weeks. Changes in anthropometry, dietary status, biochemical parameters and histopathology of liver and adipose tissue were measured. RESULTS: Rats fed with HFD were showed elevation in body weight gain and in white adipose tissue mass compared with rats consumed commercial diet. The GBR administration in 50 % GBR and 100 % GBR were significantly decreased body weight gains and food intakes as well as improved lipid profiles in obese rats. In addition, the administration of GBR  had reduced adiposity by showing declination in white adipose tissue mass, adipocytes size and leptin level concomitantly with a higher ratio of fat excretion into feces. Micro- and macrovesicular steatosis were evidently attenuated in obese rats fed GBR. CONCLUSION: These findings demonstrated that GBR exhibited anti-obesity effects through suppression of body weight gain and food intake, improvement of lipid profiles and reduction of leptin level and white adipose tissue mass in obese rats fed HFD.

Effect of germinated brown rice extracts on pancreatic lipase, adipogenesis and lipolysis in 3T3-L1 adipocytes.

BACKGROUND: This study investigated anti-obesity effects of seven different solvent (n-hexane, toluene, dicholoromethane, ethyl acetate, absolute methanol, 80% methanol and deionized water) extracts of germinated brown rice (GBR) on pancreatic lipase activity, adipogenesis and lipolysis in 3T3-L1 adipocytes. METHODS: GBR were extracted separately by employing different solvents with ultrasound-assisted. Pancreatic lipase activity was determined spectrophotometrically by measuring the hydrolysis of p-nitrophenyl butyrate (p-NPB) to p-nitrophenol at 405 nm. Adipogenesis and lipolysis were assayed in fully differentiated 3T3-L1 adipocytes by using Oil Red O staining and glycerol release measurement. RESULTS: GBR extract using hexane showed the highest inhibitory effect (13.58 ± 0.860%) at concentration of 200 µg/ml followed by hexane extract at 100 µg/ml (9.98 ± 1.048%) while ethyl acetate extract showed the lowest (2.62 ± 0.677%) at concentration of 200 µg/ml on pancreatic lipase activity. Water extract at 300 µg/ml showed 61.55 ± 3.824% of Oil Red O staining material (OROSM), a marker of adipogenesis. It significantly decrease (p < 0.05) lipid accumulation than control (OROSM = 100%), follow by ethyl acetate extract at 300 µg/ml (OROSM = 65.17 ± 3.131%). All the GBR extracts induced lipolysis with 1.22-1.83 fold of greater glycerol release than control. CONCLUSIONS: GBR extracts especially the least polar and intermediate polar solvent extracts exhibited inhibitory effect on pancreatic lipase, decrease fat accumulation by adipocyte differentiation inhibition, and stimulate lipolysis on adipocytes. Therefore, GBR could be furthered study and developed as a functional food in helping the treatment and/or prevention of obesity.

Cross-Cultural Adaptation and Validation of the Malay-Translated Version of the Food Neophobia Scale for Malaysian Young Adults.

The Food Neophobia Scale (FNS) is a research instrument, originally developed in English, to assess an individual's level of food neophobia. However, it has not yet been translated and validated for Malaysians. Therefore, we aimed to translate and validate a Malay-translated version of the FNS. Respondents were 200 young adults (mostly females, 73%; and students, 82.0%; M age = 22.3 years, SD = 2.3). We first translated the FNS into Malay using the forward-backward translation method, and a panel of nutrition and dietetics experts then reviewed it for item relevance, clarity, simplicity, and ambiguity. The translated FNS suggested good content validity with an item-level content validity index (I-CVI) > .8, a scale-level content validity index (S-CVI)/average = .8 and a S-CVI/universal agreement = .96. Principal component analysis revealed a two-factor model: (i) willingness and trust; and (ii) rejection and fear. Cronbach's alpha for the Malay-translated FNS was .808, demonstrating high internal consistency and reliability among young Malaysian adults. Future investigators can now use this Malay-translated FNS instrument to determine levels of food neophobia among Malaysians.

Consumers' Quality Perception and Acceptance of Suboptimal Food: An Online Survey in Selangor and Kuala Lumpur, Malaysia.

Suboptimal food is defined as physically imperfect food that deviates from the norm in terms of appearance without compromising its intrinsic quality or safety. Consumers' quality perception and acceptance of suboptimal food contribute to food waste. Therefore, this study aims to explore consumers' quality perception and acceptance of suboptimal food and the factors associated with the acceptance of suboptimal food. An online survey was conducted among 414 consumers residing in Selangor and Kuala Lumpur, Malaysia, through convenience sampling. They completed an online questionnaire asking for sociodemographic information, quality perception and acceptance of suboptimal food, and information related to food waste. Only 11.4% of consumers chose suboptimal foods, with visually deviated suboptimal foods (apples with brown spots) having the lowest acceptance (9.9%). Consumers perceived suboptimal foods as unattractive and that they should be consumed quickly. Malays were less likely to accept suboptimal foods, while middle-income households were more likely to accept suboptimal foods at home. In conclusion, consumers have a low acceptance of suboptimal food, and suboptimal food was perceived as unappealing and that it should be consumed quickly. Notwithstanding the findings that emerge from this, the results may lack generalisability to the wider population as only a convenience sample was used.

Factors Influencing Acceptance of Grasshoppers and Other Insects as Food: A Comparison between Two Cities in Malaysia.

Entomophagy has recently sparked widespread attention worldwide. Although entomophagy is not a foreign dietary practice in Malaysia, acceptance of insects as food among Malaysians is still unclear. This study aimed to determine the acceptance of insects as food and its influencing factors among adults living in Klang Valley (Peninsular Malaysia) and Kuching, Sarawak (East Malaysia). A cross-sectional survey was conducted involving 292 adults from Klang Valley (n = 144) and Kuching (n = 148). Data was collected through self-administrated online questionnaires. Although most respondents (96.7%) had prior knowledge of people eating insects, only 30.1% of respondents accepted insects as food, and only 18.2% reported that they would be willing to include insects in their daily diet. There was no statistically significant difference in acceptance rates between Klang Valley and Kuching. The main factors influencing respondents' acceptance of insects as food were insect texture, food safety issues and aversion toward insects. In conclusion, the acceptance of insects as food among adults in Klang Valley and Kuching is still low, with sensory characteristics, food safety and sentiments of distaste being the main barriers. Future studies involving insect tasting and in-depth focus group discussion are needed for deeper insights into the acceptance of insects as food.

A High Amylose Wheat Diet Improves Gastrointestinal Health Parameters and Gut Microbiota in Male and Female Mice.

High amylose wheat (HAW) contains more resistant starch than standard amylose wheat (SAW) and may have beneficial effects on gastrointestinal health. However, it is currently unclear whether these effects differ according to the level of HAW included in the diet or between males and females. Male and female C57BL/6 mice (n = 8/group/sex) were fed SAW65 (65% SAW; control), HAW35 (35% HAW), HAW50 (50% HAW) or HAW65 (65% HAW) diet for eight weeks. Female but not male, mice consuming any amount of HAW exhibited accelerated gastric emptying compared to SAW65 group. In both sexes, relative colon weights were higher in the HAW65 group compared to SAW65 group and in females, relative weights of the small intestine and cecum were also higher in the HAW65 group. In females only, colonic expression of Pyy and Ocln mRNAs were higher in the HAW65 group compared to HAW35 and HAW50 groups. In both sexes, mice consuming higher amounts of HAW (HAW50 or HAW65) had increased fecal bacterial load and relative abundance of Bacteroidetes phylum and reduced relative abundance of Firmicutes compared to SAW65 group. These data are consistent with a beneficial impact of HAW on gastrointestinal health and indicate dose-dependent and sex-specific effects of HAW consumption.

The Effect of Isoleucine Supplementation on Body Weight Gain and Blood Glucose Response in Lean and Obese Mice.

Chronic isoleucine supplementation prevents diet-induced weight gain in rodents. Acute-isoleucine administration improves glucose tolerance in rodents and reduces postprandial glucose levels in humans. However, the effect of chronic-isoleucine supplementation on body weight and glucose tolerance in obesity is unknown. This study aimed to investigate the impact of chronic isoleucine on body weight gain and glucose tolerance in lean and high-fat-diet (HFD) induced-obese mice. Male C57BL/6-mice, fed a standard-laboratory-diet (SLD) or HFD for 12 weeks, were randomly allocated to: (1) Control: Drinking water; (2) Acute: Drinking water with a gavage of isoleucine (300 mg/kg) prior to the oral-glucose-tolerance-test (OGTT) or gastric-emptying-breath-test (GEBT); (3) Chronic: Drinking water with 1.5% isoleucine, for a further six weeks. At 16 weeks, an OGTT and GEBT was performed and at 17 weeks metabolic monitoring. In SLD- and HFD-mice, there was no difference in body weight, fat mass, and plasma lipid profiles between isoleucine treatment groups. Acute-isoleucine did not improve glucose tolerance in SLD- or HFD-mice. Chronic-isoleucine impaired glucose tolerance in SLD-mice. There was no difference in gastric emptying between any groups. Chronic-isoleucine did not alter energy intake, energy expenditure, or respiratory quotient in SLD- or HFD-mice. In conclusion, chronic isoleucine supplementation may not be an effective treatment for obesity or glucose intolerance.

Sexually Dimorphic Response of Increasing Dietary Intake of High Amylose Wheat on Metabolic and Reproductive Outcomes in Male and Female Mice.

High amylose wheat (HAW) has a higher resistant starch content and lower glycaemic index than standard amylose wheat (SAW), which may be associated with health benefits. This study aimed to determine the effects of replacing SAW with HAW on metabolic and reproductive parameters in male and female mice. Male and female C57BL/6 mice were randomly divided into groups (n = 8/group/sex) and fed either a SAW65 (65% SAW w/w; control), HAW35 (35% HAW w/w), HAW50 (50% HAW w/w) or HAW65 (65% HAW w/w) diet for eight weeks. In male but not female, the HAW65 group had a lower abdominal circumference, relative total fat mass, relative gonadal fat mass and plasma leptin concentration compared to the HAW35 group. There were no differences in fasting blood glucose concentrations or plasma concentrations of cholesterol, triglycerides or non-esterified fatty acids between groups in either males or females. The HAW-fed males had a higher testicular weight and HAW-fed females spent less time in diestrus and a longer time in metestrus compared to the SAW-fed mice. Higher dietary intake of HAW appears to reduce abdominal fat deposition compared to the lower level of HAW in a sexually dimorphic manner. The impacts on reproductive parameters in the HAW-fed mice require further investigation.

Anthocyanidins and anthocyanins: colored pigments as food, pharmaceutical ingredients, and the potential health benefits.

Anthocyanins are colored water-soluble pigments belonging to the phenolic group. The pigments are in glycosylated forms. Anthocyanins responsible for the colors, red, purple, and blue, are in fruits and vegetables. Berries, currants, grapes, and some tropical fruits have high anthocyanins content. Red to purplish blue-colored leafy vegetables, grains, roots, and tubers are the edible vegetables that contain a high level of anthocyanins. Among the anthocyanin pigments, cyanidin-3-glucoside is the major anthocyanin found in most of the plants. The colored anthocyanin pigments have been traditionally used as a natural food colorant. The color and stability of these pigments are influenced by pH, light, temperature, and structure. In acidic condition, anthocyanins appear as red but turn blue when the pH increases. Chromatography has been largely applied in extraction, separation, and quantification of anthocyanins. Besides the use of anthocyanidins and anthocyanins as natural dyes, these colored pigments are potential pharmaceutical ingredients that give various beneficial health effects. Scientific studies, such as cell culture studies, animal models, and human clinical trials, show that anthocyanidins and anthocyanins possess antioxidative and antimicrobial activities, improve visual and neurological health, and protect against various non-communicable diseases. These studies confer the health effects of anthocyanidins and anthocyanins, which are due to their potent antioxidant properties. Different mechanisms and pathways are involved in the protective effects, including free-radical scavenging pathway, cyclooxygenase pathway, mitogen-activated protein kinase pathway, and inflammatory cytokines signaling. Therefore, this review focuses on the role of anthocyanidins and anthocyanins as natural food colorants and their nutraceutical properties for health.
