Coronavirus Disease 2019 (COVID-19), has spread worldwide, reaching pandemic proportions. The symptoms caused by COVID-19 disease are nonspecific and may range from asymptomatic to severe pneumonia and death. The aim of this study was to evaluate the potential effect of a food supplement (probiotics, prebiotics, vitamin D, zinc and selenium) in patients admitted with COVID-19. This study was a prospective, randomised, non-blinded clinical trial. A total of 162 patients were enrolled at Sagunto Hospital, 42.0% of whom were women. Participants were assigned to one of the two groups: probiotic or control group. Results showed that higher mortality was found in men, older patients and those with severe radiological involvement. Furthermore, administration of the food supplement product Gasteel Plus®, as an adjuvant to the treatment established in the hospital for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated pneumonia, reduced the duration of digestive symptoms and hospital stay in patients with mild–moderate pulmonary involvement. Authors conclude that their findings demonstrate the importance of considering the use of the food supplement under review in the prevention and treatment of SARS-CoV-2, including severe cases, which showed no side effects.
Abstract
BACKGROUND COVID-19 disease is a serious global health problem. Few treatments have been shown to reduce mortality and accelerate time to recovery. The aim of this study was to evaluate the potential effect of a food supplement (probiotics, prebiotics, vitamin D, zinc and selenium) in patients admitted with COVID-19. METHODS A prospective randomized non-blinded clinical trial was conducted in a sample of 162 hospitalized patients diagnosed with COVID-19 recruited over eight months. All patients received standard treatment, but the intervention group (n = 67) was given one food supplement stick daily during their admission. After collecting the study variables, a statistical analysis was performed comparing the intervention and control groups and a multivariate analysis controlling for variables that could act as confounding factors. RESULTS ROC curve analysis with an area under the curve (AUC) value of 0.840 (p < 0.001; 95%CI: 0.741-0.939) of the food supplement administration vs. recovery indicated good predictive ability. Moreover, the intervention group had a shorter duration of digestive symptoms compared with the control group: 2.6 ± 1.3 vs. 4.3 ± 2.2 days (p = 0.001); patients with non-severe disease on chest X-ray had shorter hospital stays: 8.1 ± 3.9 vs. 11.6 ± 7.4 days (p = 0.007). CONCLUSIONS In this trial, the administration of a food supplement (Gasteel Plus®) was shown to be a protective factor in the group of patients with severe COVID-19 and allowed early recovery from digestive symptoms and a shorter hospital stay in patients with a normal-mild-moderate chest X-ray at admission (ClinicalTrials.gov number, NCT04666116).

Plain language summary
This opinion article explores the role of an individual’s nutrition status when subjected to infection by viruses, in particular Covid-19. Distinction is made between the susceptibility to infection in the first instance and the ability to persist in fighting infection once it is established. For Covid-19, it is argued that a healthier nutritional status, in particular Vitamins A, B, C, D and E, iron selenium and zinc, will lower susceptibility to infection, lower the severity of the virus and therefore reduce the length of time an individual has to find reserves to fight the virus. More severe cases of Covid-19 infection also often include gastro-intestinal symptoms which further exacerbate nutritional status with lowered appetite. The authors conclude that malnourished individuals may be more susceptible to Covid-19 infection and that nutritional support is vital in severe cases. The article includes a useful diagram of both hyponutrition and hypernutrition and possible impacts of Covid-19.

Plain language summary
This Lebanese articled provides a commentary on the evolving COVID-19 pandemic and aims to give a framework for Nutritional action to help the physical and mental health of individuals, communities, and nations. At an individual level the focus is on the link between diet and immunity and the profound effect diet has on people’s immune system and disease susceptibility. An adequate intake of iron, zinc, and vitamins A, E, B6, and B12 is predominantly vital for the maintenance of immune function. Individuals should aim to eat as healthily as possible, including a wide range of fruits and vegetables, limit snacking, take regular exercise and get an adequate amount of sleep to support their health. Single foods promising cures or prevention of infection are unfounded claims which can give a false sense of security. The focus for communities is on food availability, for nations its food security and on a global level it is about food trade agreements. Its important to protect against hoarding and panic buying to ensure enough food for everyone. National economic instability during COVID-19 can lead to a risk of food security so governments are advised to support local agricultural produce and reduce their reliance on imported goods. Global supply chains and agreements need to be respected to lessen the impact further down the supply chain. The health of each individual has a direct impact on the community and nation and is a direct consequence of their dietary awareness and choices.

Plain language summary
Diet, as well as other lifestyle factors (sleep, exercise etc) are thought to play a significant role in the occurrence of mental disorders, including depression and anxiety. This study focused on the dietary intake of particular minerals (zinc, copper and manganese) and their effects on depression and anxiety of 2089 Japanese participants, each in full time employment. Reasons for the occurrence of mental disorders are considered multi-factorial, but insufficient mineral intake (particularly zinc) is believed to be a causal factor in the prevalence of depression and anxiety. Results of this cross-sectional study showed that low intake of zinc, copper and manganese was associated with depression and anxiety symptoms. More specifically, the effect of both low zinc and low copper intake indicated a higher susceptibility towards depression with both low and high manganese status, suggesting low zinc and copper intake contributes to depression and anxiety symptoms regardless of manganese status. Researchers acknowledge that more investigation is needed.
Abstract
Epidemiological studies have suggested that there is an association between diet and mental health. The aim of this study was to investigate the association between the intake of six minerals and mental disorders in a cross-sectional study. We used data from the Eating Habit and Well-being study in Japanese workers. Kessler's six-item psychological distress scale was used to detect mental disorders, with a cut-off score of 12/13, and a validated food frequency questionnaire was used to estimate dietary mineral intake. A total of 2089 participants with no history of depression were included. The prevalence of mental disorders was 6.9%. The lowest quartiles of zinc, copper, and manganese intakes were associated with mental disorders, whereas the lowest quartiles of calcium, magnesium, and iron intake were not associated with mental disorders. Combination analysis of high (≥median) or low (
