Whole Grain Intakes in the Diets Of Malaysian Children and Adolescents--Findings from the MyBreakfast Study.

BACKGROUND: Diets rich in whole grain are associated with several health benefits. Little is known however, about whole grain consumption patterns in Malaysia. The aim of this study was to assess whole grain intakes and dietary source in Malaysian children and adolescents. METHODS: This analysis is from the MyBreakfast study, a national cross sectional study investigating eating habits among primary and secondary school children throughout Malaysia, conducted in 2013. Children (n = 5,165) and adolescents (n = 2,947) who completed two days of dietary assessment using a food record or recall respectively were included. The whole grain content of foods was estimated mainly through the use of quantitative ingredient declarations on food labels. All wholegrain foods were considered irrespective of the amount of whole grain they contained. RESULTS: Overall, only 25% of children and 19% of adolescents were wholegrain consumers. Mean daily intakes in the total sample were 2.3g/d (SD 5.8 g/d) in children and 1.7 g/d (SD 4.7 g/d) in adolescents and in the consumer's only sample, mean intakes reached 9.1g/d (SD 8.6) and 9.2g/d (SD 7.1g/d) respectively. Wheat was the main grain source of whole grain while ready to eat breakfast cereals and hot cereals were the main food contributors. Less than 3% of the children and adolescents reached the US quantitative whole grain recommendation of 48 g/day. CONCLUSION: Whole grain is consumed by only a minority of Malaysian children and adolescents and even among consumers, intakes are well below recommendations. Efforts are needed to firstly understand the barriers to whole grain consumption among Malaysian children in order to design effective health promotion initiatives to promote an increase in whole grain consumption.

Acute Effect of Low and High Glycemic Index Meals on Post-prandial Glycemia and Insulin Responses with Type 2 Diabetes Mellitus

Introduction: Post-prandial hyperglycemia is an important independent risk factor in the development of cardiovascular disease in diabetes. This randomised cross-over study was conducted to compare the post-prandial glycemic and insulin responses to both high and low glycemic index (GI) meals in patients with type 2 diabetes (T2DM). Methods: A total of 41 patients with established T2DM (16 males, 25 males, Age= 55 ± 10 years and BMI = 27 ± 4kg/m²) were randomly given either a High GI or a Low GI meal in a cross-over manner. Both test meals were separated by one week washout periods. The meals contained almost the same amount of energy and macronutrients with the exception of the GI values (High GI=70 vs Low GI= 36). Venous blood was taken through an indwelling catheter periodically at 0, 30, 60, 90, 120, 150 and 180 minutes respectively. The incremental area under the curve (iAUC) was used to calculate the post-prandial glycemia and insulin excursion over the 3-hour period. Results: The low GI meal induced lower glycemic responses at times 30,60,90 and 120 minutes (mean±SE; low GI=8.1±0.4, 9.1±0.4 and 8.9±0.4 and 8.5±0.4mmol/l vs high GI=9.1±0.4, 10.7±0.4, 11.0±0.5 and 9.7±0.5mmol/l) and reduced the insulin levels at time 60,90,120 and 150 minutes (mean±SE; low GI=215.93±15.9mmol.L/minute vs high GI=419.52±32.7mmol.L/minute) and insulin (mean±SE;low GI=1439.76±226 vs high GI=2372.76±317mIU.ml/min) curves were lower after the low GI than high GI meal respectively (p<0.05). Conclusion: The low GI meal has the ability to reduce the post-prandial hyperglycemia as well insulin responses in type 2 diabetes patients.
