The practice of reading nutrition labels and understanding the information still remains low in Indonesia, especially among hypertensive patients. Yet, Front-of-Package Traffic Light (FoP-TL) labels can be well received by the community compared to information labels that display nutritional values. Hypertension sufferers need to understand such FoP-TL labels in order to be aware of their sodium consumption and not exceed recommended limits. The purpose of this study was to assess the effect of nutrition label designs on acceptance and understanding among hypertensive patients. The quasi-experimental study design was applied over a period of three weeks, with a control group containing 11subjects (nutritional value information labels) and an intervention group comprising 10 subjects (FoP-TL labels) selected by purposive sampling. The collection of primary data at the beginning of the study included data on the subjects’ characteristics (age, education, income, weight, height, BMI and blood pressure), knowledge of nutrition and health, their behaviour relating to the reading of nutritional value information labels, and their understanding of nutrition labels and perceptions of their attractiveness. In the first week, the subjects were given a pre-test on nutrition labels with the help of a dummy, aimed at determining their understanding of nutritional value information labels. During the second week, education was provided in the form of different booklets and dummies according to each group, while in the third week a post-test was administered to measure the effects of the nutrition labels received by both groups. The results showed significant differences in terms of the increase in understanding between the control and intervention groups (22.15 points in control group and 34.3 points in intervention group), while there were also differences in the average acceptability scores for both groups (47.7 points in control group and 55.7 points in intervention group. FoP-TL labels can thus be used to understand what constitutes good nutrition labels for use with hypertensive patients.

Introduction:The aim of this study was to investigate The effect of quercetin supplementation on oxidative stress, blood pressure, aerobic power, level of concentric pathologic hypertrophy and cardiac function in men with hypertension and CAD after PCI.\nMethods:The current study was a randomized double-blind clinical trial in which 24 men with hypertension and CAD after PCI aged 40-60 years, were participated. Patients were assigned into quercetin (250 mg/day) or placebo groups for 8 weeks. Plasma TAC and malondialdehyde (MDA) using colorimetric method, LVDD, PWd, EF and E/A using Echocardiography, WRp using the Storer-Davise Cycle Test and also blood pressure were measured at the beginning and end of intervention. Data were analyzed using paired-sample T-test and ANCOVA.\nResults:supplementation generated significant improvement in oxidative stress reduction(TAC increased and MDA decreased), systolic and diastolic blood pressure, systolic(EF) and diastolic(E/A) function and aerobic power compared to the pre test and the placebo group following eight weeks of treatment (p < 0.05). also, A small decrease in RWT was observed in quercetin group at the end of intervention, but it was not statistically significant (P = 0.132). Also, The RWT were not significantly different between groups (P = 0.52).\nConclusion: quercetin supplementation can improve the oxidative stress, blood pressure, left ventricular function and aerobic power in men with hypertension and CAD after PCI. Whereas have no effect on level of concentric pathologic hypertrophy. Further studies are needed to ensure the effect of quercetin on Left ventricular hypertrophy in human.
