“…The characteristics of functional foods were tabulated in Table 1 . Functional food components can be useful components that originate logically in or complement food as functional elements such as vitamins, minerals, dietary fiber, fatty acids, amino acids, polyphenols, phytopigments, non-saponifiable fractions, and functional plant-based proteins ( Guiné et al , 2009 ; London, 2010 ). Table 2 summarises the functional foods-based products which were quoted from the available data.…”

“…These foods and/or ingredients boost the immune response by different mechanisms ( Powell et al , 2000 ). Meanwhile, the deficiencies of one or more essential fatty and amino acids, vitamins, Se, Zn, Fe, Cu, and phytonutrients will affect almost all types of immunity ( London, 2010 ; Maggini et al , 2018 ; Zhang et al , 2020 ). Regarding COVID-19 pandemic, these functional ingredients may mitigate SARS-CoV-2 through their immunoenhancing and antiviral activity.…”

“…Eight of these nine patients stayed in Wuhan or one of their family member visited Wuhan which again confirms the human to human transmission [21]. Human to human transmission is confirmed with this new virus [11] and the basic reproductive number (R 0 ) was estimated at 2.2 [8]. Despite the lack of evidence of super spreader, at this R 0 rate, this epidemic could be the most alarming health situation for China.…”

“…However, the malnourishment can be reduced by the supply of fortified or supplemented foods. The idea of taking nourishments through regular diet, or via supplementation give insusceptible benefits ( Handu et al, 2021 ; London, 2010 ). The factors governing the innate and adaptive immunity are first discussed in this review.…”

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) - a novel coronavirus has rapid spread, and caused community infection around the globe. During the absence of a vaccine, people focused more on an immunity-boosting diet and needed clear knowledge about immunity-boosting foods. However, after the vaccination drive, the importance of food as a natural source of immunomodulation cannot be neglected. So, the purpose of this review was to describe the role of vital nutrient in boosting immune system of body apart from other factors like adequate sleep, exercise, and low stress levels. Macrophages, neutrophils, natural killer cells, dendritic cells, B-cells, and T-cells are the important components having important role in maintaining immunity of the human body. The first four-act as the initial mediator of innate host defense, and the latter two produced antibodies for pathogen destruction. The review investigated vital nutrients like vitamin-C, A, E and D, iron, zinc, folic acid, probiotics, and prebiotics affecting these immune components in some extent. Fruits, vegetables, spices, herbs, seeds, nuts, cereals, millets, and superfoods like chlorella and spirulina are good sources of these nutrients. However, fortified foods, functional foods, encapsulated foods with bioactive compounds and plant-based foods have shown immense potential in boosting immunity against viral infection like COVID-19. Some clinical trials and retrospective cohort study have shown reduction in the severity of COVID-19 patients with relation to plant-based diet, vitamin D and C doses, probiotic, and zinc salts application.
