Abstract:

Despite the relative importance of nutrition labels, a lot of Filipino consumers do not pay attention to it as documented in various literatures. Thus, there is a need to identify the factors influencing Filipino consumers to read or not to read nutrition labels among selected mothers in Las Pinas City. A quasi-experimental approach was used, 30 mothers were selected and assigned to either the group of reader or non-reader of nutrition labels. Interview schedule and guide were administered among respondents. Frequency and percentages were used to analyze data. Majority of the respondents from both groups are aware (86.7%) and know (80.0%) what nutrition labels are but reflected different views on what influences them to read or not read the labels. Among readers they view channel of information, amount of information and buying for other people as the primary factors why they read nutrition labels. The importance and usefulness of food label information increases when buying for other people, especially babies/children. Among non-readers time, overcrowding of information and physical appearance of the label are factors why they don not read nutrition labels. Most of the non-readers view these labels as too scientific and difficult to understand, complaining that the letters of the nutritional label are too small, with best before and use by, located at the back of the package, as the most confused term. In conclusion, the presentation of nutrition labels may be too technical with too much information for the consumers making it difficult to understand.

Abstract:

Introduction: Mindfulness can help college students with key challenges they face relating to weight gain and stress induced emotional eating and binge eating. Little is presently known about the extent to which students are aware of mindfulness, their conceptualization and understanding of it and the barriers as well as the facilitators of mindfulness on campus which is useful information for future health education and promotions campaigns. Additionally, promoting mindfulness through mHealth is a novel and accessible intervention medium. While there have been qualitative studies on mHealth for weight loss, there has not been a study on mHealth for weight loss using mindfulness that has explored student perspectives on mHealth for promoting mindfulness.

Method: A qualitative exploratory pilot study with a participatory design was undertaken at the St Lucia Campus at the University of Queensland in March 2017. Data was analyzed using NVivo software.

Result: The key barriers to a mindful lifestyle on campus were identified as being social, cultural, knowledge and time management related. The food environment also promoted a fast food mentality over slow mindful eating. The sample text messages were positively received by students. Students preferred messages with practical tips about how to be mindful and how to integrate mindful reflection of both one’s body and environment while on campus. Students preferred a theoretical future student-centered mindfulness app that had the following design features: A simple design interface, a focus on education/practical tips and real-life practical exercises. It is important to consider maximizing the potential facilitators of use and minimize potential identified barriers when developing and designing a future mHealth mindfulness intervention.

Conclusion: Future mHealth studies may consider integrating mindfulness-based text messages in their interventions for weight and stress as this is a novel feature that appears to be acceptable for students.

Abstract:

Diet is considered a risk factor in chronic degenerative diseases such as cancer. The Fumonisin are mycotoxins with cancer evidence in animal models and they are classified by IARC as a possible human carcinogen group 2b. These toxins commonly infect cereal crops. Maize (corn) is the principal food cereal consumed by Mexican population as tortillas in significant amounts. The aim of this research was to investigate the fatty acid profile in 40 genotypes of maize with natural fumonisin contamination. The fatty acids profile was performed by gas chromatography and total Fumonisin were determined using the QuickTox TM extraction and quantified by QuickScan. The results showed that linoleic acid increased in hybrid maize contaminated with mycotoxins versus maize not contaminated, in average 7.6% (47.12% vs 39.57% respectively). The oleic acid was the principal loss in hybrid maize (6.62%). 31% of the hybrid maize with fumonisin at average levels in 0.26 ppm (260 ppb), with a range of 0.23 to 1.20 ppm (230-1200 ppb); 22% of native corn with an average content of 0.41 ppm (410 ppb) and a maximum of 1.0 ppm (1000 ppb). In the statistics analysis, a Pearson correlation test was made (Excel) and showed significance between fumonisin and linoleic acid (p >0.05.) The conclusion was the linoleic acid is affected by even in low levels of Fumonisin in both genotypes and 123.5 million people are in risk of chronic exposure to mycotoxins and develop cancer.

Abstract:

Statement of the Problem & Aim: Overweight and obesity are associated with various co-morbidities. With this background, present study aims to screen and identify school going adolescents with hypertriglyceridemia and hypertriglyceridemic waist phenotype among adolescents of Delhi.

Method: Cross-sectional study was done with 877 adolescents (12-15 years) selected from four public schools of Delhi. Based on body mass index, waist circumference and waist to height ratio subjects were screened to identify high risk subjects. Of the screened subjects’ serum triglycerides was estimated to identify hypertriglyceridemia and hypertriglyceridemic waist phenotype.

Result: 33.2% of subjects were screened and their serum triglycerides was estimated. Hypertriglyceridemia among subject was 35.7% (males 32.9%, females 41.3%, p=0.4). Triglycerides were significantly associated with BMI (r=0.12, p=0.04); WC (r=0.19, p≤0.001) and body weight (r=0.10, p=0.03). Waist circumference (≥90 percentile) had higher odds for having an elevated serum triglyceride concentration (OR=2.08, 95% CI=1.19-3.63) in comparison to waist circumference <90 percentile. Prevalence of hypertriglycemic waist phenotype among screened subject was 26.20% (males 25.6%, females 27.1%, p=0.06). Higher prevalence of hypertriglycemic waist phenotype was seen in obese subject in comparison to overweight subjects (p=0.002). Similarly, higher prevalence hypertriglycemic waist phenotype was seen in subject with waist to height ratio greater than 0.5 in comparison to waist to height ratio less than 0.5 (p=0.00).

Conclusion: High prevalence of hypertriglyceridemia and hypertriglyceridemic waist phenotype among adolescents indicates need of proactive preventive measures with focus on diet and physical activity to avoid future non-communicable disease epidemic and related co-morbidities.

Abstract:

The re-scoring method of Subjective Global Nutrition Assessment (SGNA) has 5 categories in defining malnutrition. Recently, it has been validated with Registered Dietitians’ assessment as standard and effectively has shown comparable agreements. The re-scoring method was applied noticing malnutrition and its prevalence in various conditions. The objective of study was determining malnutrition prevalence in pediatric cancer inpatient using SGNA re-scoring method. A cross-sectional study was conducted in a tertiary level non-infection pediatric ward hospital during January to May 2018. Cancer patient in critical illness were excluded. There were 307 subjects pleased inclusion criteria with majority was children-age group (60%) followed by adolescent (34.5%) and infant (5.5%). Composition between genders was relatively comparable (boys 55%, girls 45%). Based on cancer type, most of subjects had solid tumor (59.3%) tailed by leukemia (35.2%) and lymphoma (5.5%). SGNA identified 40.2% subjects were malnutrition (moderate 33.2%, severe 7%), while SGNA re-scoring method classified 36.2% subjects were normal, 37.1% mild, 20.8% mild-moderate, 5.6% moderate and 0.3% severe malnutrition. Malnutrition prevalence in pediatric cancer is relatively high on admission. Classification using the re-scoring method of SGNA is more featured to differentiate between mild and moderate malnutrition compared with SGNA. This will assist Registered Dietitians to prioritize patient and their progressive nutrition therapy which will be delivered in preventing worse conditions in time as early as possible.

Abstract:

This study aimed to determine the relationship between the intake of n-3 and n-6 fatty acids and the incidence of depression in college students. The study especially tested whether the association between the two was strong enough to be significant despite the effects of confounders found in college environment. A cross sectional questionnaire survey was conducted to collect the different from two hundred one (201) college respondents for this study. Usual food intake recall (UFIR) was used to determine the n-3 and n-6 fatty acid intake; beck depression inventory- II (BDI - II) for the ascertainment of depressive symptoms and a miscellaneous questionnaire for the determination of confounders. The study used the binary hierarchical logistic regression analysis to analyze the data. The results showed that there was significant relationship between n-3 and n-6 fatty acid intake and depressive symptoms in college students (χ²=12.39, df=1; p<0.000). The n-3 and n-6 fatty acid intake variable strongly predicted the incidence of depressive symptoms in the hierarchical model (p<0.001; df=1) and that the association was independent from the influence of the confounders. The odds ratio for a college student with adequate n-3 and n-6 fatty acid intake to have no depressive symptoms is 4.509 times more than a college student with inadequate intake (95% CI=1.857 to 10.949).

Abstract:

In recent years, natural resources are attracting more attention due to their huge potential in discovery/development of novel bioactive compounds. Mushrooms and their metabolites have made them ideal candidates for health supplement due to beneficial effects. However, only limited mushrooms and compounds have been discovered and applied in nutraceutical industry compared with abundant natural resources. In our study, mono-culture and mixed-culture of mycelia of medicinal mushrooms, three edible mushrooms and 11 wild-type mushroom strains isolated in Singapore rain forest were investigated for enhanced bioactivity and novel secondary metabolites. Both mycelia and fermentation broth were extracted and analyzed. The results showed that triterpenoids were the main bioactive compounds from the extract samples and their production was enhanced through mycelial co-cultivation. In addition, mycelia co-cultivation also resulted in enhanced anti-oxidant and anti-diabetic activities. More interestingly, the secondary metabolite profiles varied greatly between mono-culture and co-culture with novel compounds detected in mushroom mycelia co-cultivation. Our study demonstrated that mixed-culture fermentation of mushroom mycelia may be an effective strategy to discover novel bioactive compounds and develop novel nutraceutical products.

Abstract:

Metabolic flexibility refers to the ability of the muscle to effectively switch between substrates supplying energy based on availability. Although a decline in FTO transcription has been associated with alterations in glucose and lipid metabolism, it is unknown if this subsequently influences metabolic flexibility. This study investigated the influence of FTO rs9939609 genotype (variant alleles: AA, AT and TT) and BMI (lean: <25 kg/m² and overweight: >25 kg/m²) on metabolic and respiratory markers of substrate oxidation in the basal state and following a glucose-stimulated dietary challenge. Apparently healthy, sedentary males and females aged 20-50 years (n=147) completed a single experimental session designed to (1) assess pre-prandial plasma glucose and serum insulin concentrations, Respiratory Exchange Ratio (RER) and substrate oxidation following a 10-12 hours overnight fast and (2) assess the physiological responses of these variables following an Oral Glucose Load (OGL) challenge. Metabolic flexibility (measured as ∆RER over time) was slower in overweight individuals compared to lean individuals (p=0.009), but not different between FTO genotypes (p>0.05), independent of BMI. Overweight individuals demonstrated lower pre-prandial fat oxidation (p=0.012) and elevated pre-prandial glucose oxidation (p=0.031) compared to lean individuals. No differences in pre-prandial or post-prandial substrate oxidation were observed between FTO genotypes (p>0.05). Plasma glucose was significantly increased post OGL (p<0.001), however, no differences were observed when separating participants by BMI or FTO genotype (p>0.05). Significantly greater insulin resistance was observed in overweight individuals when compared to lean individuals (p=0.007), whilst insulin resistance and sensitivity were similar between FTO genotypes (p>0.05). An acute nutritional stimulus produced a slower metabolic flexibility and higher insulin resistance in individuals with an overweight BMI but did not produce different responses between FTO allelic variants.​​
