Recently, there has been an emerging trend of purchasing foods and beverages via online food delivery systems but there is scarce evidence on the healthfulness of these items, particularly in Southeast Asian countries such as Malaysia. This study aimed to evaluate the characteristics and nutrient profiles of foods and beverages available via online food delivery systems in Malaysia. This cross-sectional study was conducted from September 2022 to March 2023 to identify foods and beverages available on the Grab Food and Foodpanda mobile applications. The healthfulness of selected foods and beverages was determined based on the Food Standards Agency Nutrient Profiling System. The present study included 3729 foods and 1882 beverages. Most of the foods were cereal-based dishes (37.4%), followed by cereals with protein-based dishes (12.8%) and meat or poultry-based dishes (12.0%), while most of the beverages were local handcrafted beverages (27.8%), followed by bubble milk tea (15.0%) and Western handcrafted beverages (14.6%). For protein dishes, deep-frying or battered-frying was the most common preparation method (33.8%) while most of the cereal-based dishes were stir-fried (76.7%). Out of 23 common foods, 15 foods (65%) were categorised as less healthy based on the nutrient profile score while 19 out of 24 (79%) common beverages were categorised as less healthy. The online food delivery systems feature predominantly local foods and beverages that are less healthy, potentially contributing to the development of an obesogenic environment.
MicroRNAs are small non-coding RNA that regulate gene expressions of human body. To date, numerous studies have reported that microRNAs possess great diagnostic and prognostic power in head and neck cancer and had governed a lot of attention. The factor for the successfulness of miRNAs in these aspects is due to cancer being fundamentally tied to genetic changes, which are regulated by these miRNAs. Head and neck cancer, leading the world record for cancer as number sixth, is caused by multiple risk factors such as tobacco consumption, alcohol consumption, dietary factors, ethnicity, family history, and human papilloma virus. It derives at locations such as oral cavity, pharynx, larynx, paranasal sinus and salivary gland and have high rate of mortality with high recurrence rate. Besides, head and neck cancer is also usually having poor prognosis due to its asymptomatic nature. However, this diagnostic and prognostic power can be further improved by using multiple panels of miRNA as a signature or even combined with TNM staging system to obtain even more remarkable results. This is due to multiple factors such as tumour heterogeneity and components of the tumour which may affect the composition of miRNAs. This review covers the examples of such miRNA signatures, compare their diagnostic and prognostic powers, discuss some controversial roles of unreported miRNAs, and the molecular mechanisms of the miRNAs in gene targeting and pathways.
