This study was aimed at assessing the antioxidant capacity and phenolic (free, bound, and total) contents in selected commercial beverages. Three different types of beverages commonly available in Malaysian supermarkets namely, cocoa, coffee and tea were selected. Phenolic contents were determined using a Folin-Ciocalteu assay. Antioxidant capacity (ferric reducing power and scavenging activity) was determined using FRAP and TEAC assays. Based on analysis of variance, coffee showed the highest amount of free phenolic compounds and antioxidant capacity compared to cocoa and tea (p < 0.05). The major phenolic compound detected in coffee was chlorogenic acid. Cocoa showed higher phenolic content than tea. However, cocoa and tea have similar catechin content and possessed comparable antioxidant capacity. The free phenolic content in the three beverages was found to be highly correlated with antioxidant capacity. In addition, moderate correlation was observed between total phenolic content and antioxidant capacity. On the other hand, there was no significant contribution of bound phenolic compounds towards antioxidant capacity. The contribution of antioxidant capacity in these beverages could be due to phenolic compounds in the free form. The study indicated that the beverages studied possessed varying degrees of antioxidant capacity and phenolic contents.

Overweight and obesity are major health concerns in Malaysia, which are linked to other health consequences such as type 2 diabetes mellitus, cardiovascular diseases and several others. Among dietary factors, sugar-sweetened beverages (SSBs) are reported to be one of the leading factors of weight gain and a higher body mass index (BMI). Sugar-sweetened beverages are beverages with added sugar that only add calories to an individual’s normal diet and they represent the largest contributor to the added sugars intake. This study was aimed to determine the prevalence of SSB consumption among university students in Kuala Nerus, Terengganu, as well as to investigate the association between the students’ SSB consumption and their BMI. A cross-sectional study was conducted among 350 Universiti Sultan Zainal Abidin (UniSZA) Gong Badak Campus and Universiti Malaysia Terengganu (UMT) students by using the convenience sampling. Each participant was given a questionnaire consisting of socio-demographic details, anthropometric assessment and beverage intake. The results revealed that half of the students consumed 2 cups (500 mL) of SSBs on average days (49.4%), whereas 21.7% of them consumed at least 3 cups daily. It was found that sweetened tea was the students’ most preferred SSB and there was also an association between the SSB consumption and the BMI. In conclusion, university students in Kuala Nerus drink 2 cups of SSBs daily and sweetened tea is their preferred SSB. Since the students’ SSB consumption influences their BMI, these students must be aware on the contents of SSB and the related health consequences in order to reduce the consumption of these beverages and hence, reduce their BMI to a healthy level.

Antioxidant activity, free radical scavenging activity and phenolic content of red cabbage (Brassica oleracea var. capitata rubra), Chinese cabbage (Brassica rapa pekinensis var cylindrica), green cabbage (Brassica oleracea var capitata), mustard cabbage (Brassica juncea var rugosa) and Chinese white cabbage (Brassica rapa var chinensis), grown in Malaysia, were evaluated. Red cabbage had the highest antioxidant activity and phenolic content compared to the other cruciferous vegetables studied (p < 0.05). The contributions of all cruciferous vegetables to the antioxidant activity was >79%. The radical scavenging activity was in the order of Chinese white cabbage > red cabbage > mustard cabbage > Chinese cabbage > green cabbage. There was a significant difference (p < 0.05) in the means of scavenging activity observed between cabbage, Chinese cabbage and Chinese mustard. Phenolic content was significantly different (p < 0.05) among all the cruciferous vegetables studied, and was in the order of red cabbage > Chinese white cabbage > green cabbage > Chinese cabbage >mustard cabbage. The study indicated that red cabbage possessed the highest antioxidant capacity and phenolic compounds concentration among all the cruciferous vegetables studied.

Introduction: The consumption of sugar-sweetened beverages (SSBs) among young adults in Malaysia has witnessed
a notable increase in recent years, giving rise to concerns regarding the potential adverse health effects, including
obesity and diabetes. Despite the urgent need for targeted interventions, there is a dearth of research examining the
knowledge, attitudes, and practices (KAP) related to SSBs among Malaysian young adults. To address this research
gap, the present study aims to assess the level of KAP concerning SSB intake and its associated factors in this specific
population. Methods: A cross-sectional study was conducted involving 408 Malaysian young adults aged between
15 and 29 years. Respondents completed an online questionnaire survey, which encompassed the assessment of
socio-demographic characteristics and KAP regarding SSB consumption. The collected data were analyzed using
IBM’s Statistical Package for the Social Sciences (SPSS) version 22.0. Spearman correlation tests were performed
at a significance level of 0.05. Results: The majority of respondents demonstrated moderate knowledge (60%) and
practices (60%), while exhibiting a high positive attitude (100%) towards reducing SSB consumption. Significant
correlations were observed between knowledge and attitude (p = 0.003, rs = 0.148) and between knowledge and
practice (p = 0.005, rs = 0.138). Moreover, the attitude scores were found to be significantly associated with gender
(χ2
(1, N = 408) = 10.421, p = 0.001) and locality (χ2
(1, N = 408) = 4.106, p = 0.043), while the practice scores
exhibited a significant association with ethnicity (p = 0.006). Conclusion: This study provides valuable insights into
the relationship between KAP related to SSB consumption and socio-demographic factors among Malaysian young
adults. The findings underscore the importance of utilizing these insights to develop strategic interventions that aim
to curtail SSB consumption and promote a healthy lifestyle, ultimately contributing to the reduction of non-communicable diseases. Health authorities are encouraged to capitalize on these findings to design targeted interventions
tailored to the unique needs and circumstances of this population.
