Poor diets are the major cause of death and disease globally, driving high levels of obesity and noncommunicable diseases. Cheap, heavily marketed, ultra-processed, energy-dense and nutrient-poor food and drinks that are high in fat, sugar and salt play a major role. The high-sugar content of these products leads to consumption levels much higher than recommended.

Cardiovascular diseases (CVDs) are the major cause of death among Malaysians. Reduction of salt intake in populations is one of the most cost-effective strategies in the prevention of CVDs. It is very feasible as it requires low cost for implementation and yet could produce a positive impact on health.

Objective: To explore the perspectives, barriers and enablers on salt reduction in out-of-home sectors in Malaysia among street food vendors, caterers and consumers.

Design: A qualitative study involving twenty-two focus group discussions and six in-depth interviews was conducted, recorded and transcribed verbatim. An inductive thematic analysis approach was employed to analyse the data.

Article Synopsis
  • A study assessed changes in salt intake, blood pressure (BP), and cardiovascular disease (CVD) mortality in England from 2003 to 2018, using national survey data.
  • Salt intake decreased from 9.38 g/d in 2003 to 7.58 g/d in 2014, then increased slightly to 8.39 g/d in 2018, which coincided with similar trends in BP and CVD mortality.
  • The initial success of the UK salt reduction program led to a 19% decrease in salt intake and corresponding improvements in BP and CVD mortality; however, the progress stalled in recent years, showing a need for renewed efforts.

Background: High salt intake is a major cause of hypertension and cardiovascular diseases. The out-of-home sectors have been identified as one of the contributors of high salt intake in the population. The National Salt Reduction Policy of Malaysia was initiated in 2015; however, out-of-home sectors are yet to be emphasized and perception by policy-makers and the food industries towards salt reduction are yet unknown.

Background: The US Food and Drug Administration (FDA) proposed 2- and 10-year voluntary sodium-reduction targets for >150 packaged- and prepared-food categories in 2016 and finalized the short-term targets in 2021.

Methods: We modeled the health benefits of implementing the newly finalized sodium targets, and the net health losses because of the 4.3-year delay in finalizing the sodium targets in different compliance scenarios in adults aged ≥30, using the National Health and Nutrition Examination Survey (NHANES) 2015 to 2016 cycle.

Article Synopsis
  • Plant-based meat (PBM) is becoming more popular due to health, animal welfare, and environmental concerns, prompting a study to analyze its nutrient profile against conventional meat products.
  • A survey of 207 PBM and 226 meat products from 14 UK retailers found PBM had lower energy density, total fat, saturated fat, and protein, but higher fiber; salt content was higher in some PBM categories.
  • Overall, while PBM generally had a better nutrient profile than meat, many PBM products still exceeded UK salt targets, indicating the need for improvement in their formulations.

Background: Suboptimal diets are a leading risk factor for death and disability. Nutrition labelling is a potential method to encourage consumers to improve dietary behaviour. This systematic review and network meta-analysis (NMA) summarises evidence on the impact of colour-coded interpretive labels and warning labels on changing consumers' purchasing behaviour.

In this review, we have investigated the perceptions, barriers, and enabling factors that were responsible for a dietary salt reduction in the out-of-home sectors. For this purpose, we examined different knowledge databases such as Google Scholar, Ebscohost, MEDLINE (PubMed), Ovid, and Cochrane Library for research articles from September to December 2020. The inclusion criteria for the research articles were that they had to be published in English and had to be a qualitative or quantitative study that was conducted after 2010.

Introduction: Current salt intake in Malaysia is high. The existing national salt reduction policy has faced slow progress and does not yet include measures to address the out of home sector. Dishes consumed in the out of home sector are a known leading contributor to daily salt intake.
