The positive association between excessive dietary sodium intake, hypertension, and cardiovascular disease (CVD) has been widely investigated in observational studies and clinical trials. Reducing sodium intake is a proven strategy to prevent hypertension and the onset of CVD, a major cause of morbidity and mortality globally. Africa has the youngest population globally, which is key to the continent’s sustainable development. However, in Africa, the epidemics of hypertension and CVD negatively impact life expectancy and economic growth. Ghana, like other African countries, is no exception. The factors contributing to the increasing burden of CVD and excessive sodium consumption are multi-faceted and multi-level, including individual lifestyle, neighborhood and built environments, and socio-economic and health policies. Thus, the implementation of evidence-based interventions such as the World Health Organization Best Buys that target the multi-level determinants of sodium consumption is urgently needed in Ghana and other African countries. The aim of this commentary is to highlight factors that contribute to excessive sodium consumption. Second, the commentary will showcase lessons of successful implementation of sodium reduction interventions in other countries. Such lessons may help avert CVD in young adults in Ghana and Africa.

One major micronutrient studied for its possible protective effect against the COVID-19 disease is vitamin D. This systematic review sought to identify and synthesize available evidence to aid the understanding of the possible effect of vitamin D deficiency on COVID-19 status and health outcomes in COVID-19 patients. Three databases (PubMed, ScienceDirect, and Google Scholar) were systematically used to obtain English language journal articles published between 1 December 2019 and 3 November 2020. The search consisted of the terms (“Vitamin D,” OR “25-Hydroxyvitamin D,” OR “Low vitamin D.”) AND (“COVID-19” OR “2019-nCoV” OR “Coronavirus” OR “SARS-CoV-2”) AND (“disease severity” OR “IMV” OR “ICU admission” OR “mortality” OR “hospitalization” OR “infection”). We followed the recommended PRISMA guidelines in executing this study. After going through the screening of the articles, eleven articles were included in the review. All the included studies reported a positive association between vitamin D sufficiency and improved COVID-19 disease outcomes. On the other hand, vitamin D deficiency was associated with poor COVID-19 disease outcomes. Specifically, two studies found that vitamin D-deficient patients were more likely to die from COVID-19 compared to vitamin D-sufficient patients. Three studies showed that vitamin D-deficient people were more likely to develop severe COVID-19 disease compared to vitamin D-sufficient people. Furthermore, six studies found that vitamin D-deficient people were more likely to be COVID-19 infected compared to vitamin D-sufficient people. Findings from these studies suggest that vitamin D may serve as a mitigating effect for COVID-19 infection, severity, and mortality. The current evidence supports the recommendations for people to eat foods rich in vitamin D such as fish, red meat, liver, and egg yolks. The evidence also supports the provision of vitamin D supplements to individuals with COVID-19 disease and those at risk of COVID-19 infection in order to boost their immunity and improve health outcomes.
