Introduction: The aim of this study was to assess the overall diet quality of husbands and wives in a selected urban area in Selangor.
Methodology: This cross-sectional study was carried out in Bandar Baru Bangi, Selangor among 150 married couples aged 20 and above, who voluntarily agreed to participate and were not practicing any special diet. Data were collected using a 2-day 24-Hour Dietary Recall and a Food Frequency Questionnaire (FFQ) to evaluate the quality of diet among husbands and wives using the Diet Quality Index Revised (DQI-R).
Result: Majority of husbands and wives in this study were in the middle-age group, had received tertiary education, had household monthly income of more than RM3, 500 and encompass household size of 3 to 5 persons. The mean DQI-R score for husbands (mean age= 43.33 + 11.16 years) and wives (mean age= 41.28 + 10.93 years) were 67.8 + 9.1 and 64.4 + 9.3 respectively and there was a significant different in scores between the husbands and wives (p < 0.001). In general, the diet quality of this study population was not satisfactory and that the diet quality of husbands was better compared to their wives.
Conclusion: This study gives an insight picture of husbands and wives’ quality of diet. It can be used as a guideline to improve health intervention programs in the future.
This study investigated the protein quality of two sets of Roselle seeds processed differently (dried and boiled). Twenty weanling Sprague Dawley rats were used to conduct the growth and nitrogen balance studies. Rats were fed with 10% (w/w) protein from dried (DS) and boiled (BS) Roselle seeds powder for 4 weeks. Casein was used in this study as a standard reference protein. There was a significantly higher (p < 0.05) food intake and weight gain by rats fed with BS compared with DS. In the growth study, there was no significant difference (p < 0.05) in protein efficiency ratio (PER) and net protein ratio (NPR) of BS compared to DS, but it was significantly different with casein (CD). PER value of rats fed with DS was significantly lower (p < 0.05) than casein. In the nitrogen balance study, true nitrogen absorption (TNA) and nitrogen balance (NB) of BS group was significantly higher (p < 0.05) than DS group. However, apparent digestibility (AD), true digestibility (TD) and biological value (BV) for both diets was not significantly different. This study showed that the protein quality of dried Roselle seeds was similar to the Roselle seeds boiled at 100oC for 30 minutes.
The objective of the study was to investigate the hypoglycaemic properties of Malaysian cocoa (Theobroma cacao) polyphenols extract in-vivo and insulin sensitivity in-vitro. Cocoa extract (CE) (containing 190 - 286 mg total polyphenol per gram extract) was prepared from fermented and roasted (140°C, 20 min) beans by extracting with 80% ethanol in the ratio of 1 to 10. For the in-vivo study, the CE was administered in three dosages (1%, 2%, and 3%) to groups of normal and diabetic rats for a period of 4 weeks by forcefeeding. Results showed that dosages of 1% and 3% CE significantly reduced (p < 0.05) plasma glucose levels in the diabetic rats. An in-vitro study (BRIN-BD11 cell lines) was used to evaluate the effect of CE on insulinsensitivity. The results demonstrated that CE at a concentration of 0.1 mg/ml significantly increased (p < 0.05) insulin level compared to the control. The results of this study showed that Malaysian cocoa polyphenol extract have the potential of being an insulin-mimetic agent. Further studies are on-going to elucidate the underlying mechanisms of polyphenols present in CE that contribute to the reduction of plasma glucose levels and insulin mimicking activity.
