ABSTRACT
@#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.
ABSTRACT
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 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 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.

BrassicaABSTRACT
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.
