\begin{abstract}
A natural immune booster is an additional immunizing agent which helps to increase and sustain the immune response of the body. Circumin is an active compound in turmeric which is a natural antioxidant which is used as an immune booster, antimicrobial, antipathogen and as a detoxifying agent. Pepper contains piperine that has antioxidant potential which will decrease the level of lipid peroxidase and has immunomodulatory activity, it increases macrophage migration index and phagocytic index. The vitamin C is a powerful antioxidant that reduces the duration and severity of upper respiratory tract infections. Along with natural immune boosters, healthy practices like yoga and meditation will regulate and maintain organ functions, thereby improving our immunity. The main aim of the study is to create an awareness on natural dietary immunoboosters to combat COVID 19. A self structured questionnaire comprising of about 15 questions was prepared and circulated through online based i.e. Google forms. The results were obtained and statistically analyzed through SPSS software. The survey was done on a small scale population comprising 110 participants in which 62 male (56.4\%) and 48 female (43.6\%) participated. About 95.5\% of the population are aware that taking citrus fruits that have vitamin C will boost their immunity but only 4.5\% of them are not aware. 80\% of the population are aware that green tea is a powerful antioxidant which will help in building immunity but 9.1\% were not aware and 10.9\% was not sure of the fact. 82.7\% of the population are well aware that spinach and other green vegetables have to be cooked as little as possible to retain nutrients present in them but only 10.9\% of them were not sure and 6.4\% of them were not aware.

\section{Introduction}
A Natural immune booster is an additional immunizing agent which helps to increase and sustain the immune response of the body. The immune response is evoked by our body \unskip~\citep{846859:19954867}. Curcumin is an active compound in turmeric which is a natural antioxidant which is used as an immune booster, antimicrobial, antipathogen and as a detoxifying agent \unskip~\citep{846859:19954873}. Pepper contains piperine that has antioxidant potential which will decrease the level of lipid peroxidase and has immuno modulatory activity, it increases macrophage migration index and phagocytic index. These indices confirm piperine is an immunobooster \unskip~\citep{846859:19954876}.

Respiratory diseased patients like asthma and wheezing patients will generally have low immunity, so they are easily prone to immunity, so they are easily prone to communicable and pandemic diseases. So these patients should be precautious and should have a proper diet and lifestyle \unskip~\citep{846859:19954859} and even due to having pets at home, may cause respiratory disease \unskip~\citep{846859:19954853}. If proper diet is taken, the risks of getting fatty liver disease \unskip~\citep{846859:19954875}, neonatal jaundice and kernicterus \unskip~\citep{846859:19954860} is lowered. Snoring is a life threatening condition where the individual fails to have proper sleep quality which makes them fall sick often \unskip~\citep{846859:19954856} and will mostly have lower back pain \unskip~\citep{846859:19954854}. Onychocryptosis is a condition in which the corner of the toenail grows into flesh and this condition is not caused due to fall in immunity, it is of genetic origin or poor nail hygiene and maintenance \unskip~\citep{846859:19954872}. Removal of adenoids due to various pathological reasons results in increased risk of developing respiratory infections and allergic conditions, thereby it is important that such individuals should take more dietary immune supplements \unskip~\citep{846859:19954869}.

Previous research by  \unskip~\citet{846859:19954857} gave 6 smart steps to build immunity against COVID 19, the study explained how vitamins improve the immunity through dietary nutrients which are immunity stimulatory agents. The study also gave nutritional diets for immunity. Another study by \unskip~\citet{846859:19954870} concluded that supplementation of vitamin D\ensuremath{_{3}} or D\ensuremath{_{2}} will lower the risk of acute respiratory infections. So the supplementation of vitamin D will be useful for patients of respiratory infections. The study by  \unskip~\citet{846859:19954855} was studied to know the general public knowledge on the preventive behaviours against H\ensuremath{_{1}}N\ensuremath{_{1}} pandemic, so, the public knowledge was known among people of kingdom of Bahrain, this study was supported by \unskip~\citet{846859:19954858} was studied to know the knowledge, attitude and practices during swine flu pandemic.  The cure for COVID 19 is still unknown, so people should know how to be aware of preventing themselves from the infection by taking natural food supplements. The main aim of the study is to create an awareness on natural dietary immunoboosters to combat COVID 19 and to study their knowledge on natural dietary immunoboosters.

\section{Materials and Methods}
The study was done as an online setting which is a prospective observational study. The pros of the study were large numbers of data that can be stored and was cost effective and easy to handle and cons where the options may not be available to the participant and the participants truthfulness cannot be tested. A self structured questionnaire comprising about 15 questions was prepared and circulated through google forms. The statistics test that was

The survey was done on a small scale population comprising 110 participants in which 62 male (56.4\%) and 48 female (43.6\%) participated (Figure~\ref{f-d58b8ce29c8b}). From the survey, it was found that 95.5\% of the population were aware of the fact that taking citrus fruits having vitamin C will boost their immunity but only 4.5\% of them were not aware of the same (Figure~\ref{f-6c38cd6fe22a}). 52.7\% of the population were aware that Beta carotene improves immune function, but 18.2\% were not aware and 29.1\% were not sure of the fact (Figure~\ref{f-98588bd0cdb0}). Among biotin, chromium, ginseng, vitamin B\ensuremath{_{6}}; the supplements that help us to ward off flu were answered as 9.1\% biotin, 2.1\% chromium, 19.1\% ginseng (correct answer) and 69.1\% vitamin B\ensuremath{_{6}} (Figure~\ref{f-42f4915130b8}). 80\% are aware that green tea is a powerful antioxidant which will help in building immunity but 9.1\% were not aware and 10.9\% were not sure of the fact (Figure~\ref{f-c67f59c716d1}). 82.7\% of the population were well aware that spinach and other green vegetables had to be cooked as little as possible to retain nutrients present in them but only 10.9\% of them were not sure and 6.4\% of them were not aware (Figure~\ref{f-f162fdce1bd6}). Mostly about 92.7\% of them were well aware that spices and condiments of the Indian kitchen would definitely help in regulating the immune system, but 7.3\% were not aware of the fact (Figure~\ref{f-56cc37ea2fd7}). Then, among calcium, manganese, potassium, zinc; the mineral for maintaining optimal immune function were answered as 34.5\% calcium, 8.2\% manganese, 12.7\% potassium, 44.5\% zinc as zinc is the mineral that maintains optimal immune function as zinc regulates immune function as its deficiency suppresses immune function (Figure~\ref{f-d64022822eb5}). Among omega 3 fatty acid, simple sugars, trans fat, the nutrient that improves immune function was answered as 69.1\% omega 3 fatty acid, 22.7\% simple sugars, 8.2\% trans fat, so most of the population were aware that omega 3 fatty acid is the nutrient that improves immune function (Figure~\ref{f-0ef1be266214}). 79.1\% of the population were aware that chicken soup improves the immune system during cold but 20.9\% were not aware of the fact (Figure~\ref{f-42d26c4ab0a8} ). Among beta carotene, vitamin B\ensuremath{_{12}}, vitamin C, vitamin D, the orange colored vegetables that contains powerful antioxidants was answered as 51.8\% beta carotene, 18.2\% vitamin B\ensuremath{_{12}}, 25.5\% vitamin C, 4.5\% vitamin D, most of them were not aware that beta carotene is present in orange colored vegetables which is a powerful antioxidant (Figure~\ref{f-ca3958f69578}). 35.5\% of them were aware that chicken containing vitamin B\ensuremath{_{6}} helps in growth of new RBC but 36.4\% of them were not sure and 28.2\% were not aware of the fact (Figure~\ref{f-976eb1d4d51c}). About 84.5\% believe that eating fresh fruits and vegetables will help us to combat COVID 19 by boosting immunity but only 15.5\% was not aware of the fact (Figure~\ref{f-977359a2e68f}). Nearly 75.5\% agreed that staying hydrated would help to regulate immunity to fight COVID 19 only 17.3\% were not sure and 7.3\% of them were not aware of the fact (Figure~\ref{f-393fd97ea4d8}). 40\% of the population were aware that low carb diet would reduce the risk of COVID 19 but nearly 40.9\% were not sure of the fact and 19.1\% of them were not aware (Figure~\ref{f-3155e0292037}). 82.7\% of them were aware that ginger, amla, turmeric are natural immunity supplements that help against COVID 19 infection, only 5.5\% were not aware and 11.8\% were not sure of the health benefit behind it (Figure~\ref{f-cb7c464a94e1}). The Chi square analysis was done using gender as a fixed parameter and the p value with their significance was obtained (p \ensuremath{\leq } 0.05 means statistically significant; p {\textgreater} 0.05 means not statistically significant). The Chi square analysis was performed between gender and awareness of chicken soup that improves immunity during cold and the p-value was found as 0.017 and it was observed as statistically significant (Figure~\ref{f-f003503b2dc6}). The Chi square analysis was performed between gender and awareness of chicken containing vitamin B\ensuremath{_{6}} that helps in growth of new RBC and the p-value was found as 0.153 and it was not statistically significant (Figure~\ref{f-9ebb53c9835b}). The Chi square analysis was performed between gender and awareness of orange colored vegetables that are antioxidants containing beta carotene and the p-value was found as 0.132 and it was not statistically significant (Figure~\ref{f-630ca387ce37}). The Chi square analysis was performed between gender and belief of eating fresh fruits and vegetables would boost immunity against COVID 19 and the p-value was obtained as 0.198 and it was not statistically significant (Figure~\ref{f-9a1c9a4189ff}). The Chi square analysis was performed between gender and awareness of ginger, amla and turmeric that are immunity supplements which help against COVID 19 and the p-value was obtained as 0.504 and it was not statistically significant (Figure~\ref{f-49af82d4aed4}).

Previous study by  \unskip~\citet{846859:19954871} concluded that 71.1\% of the population are aware that turmeric has medicinal properties that fight against any pathogens, in the present study it is observed that about 82.7\% of the population are aware that ginger, turmeric, amla help us to fight against present pandemic issue which is also supported by another study by  \unskip~\citet{846859:19954877} concluded that 92.6\% of the population was aware that ginger has role in infection control. A study by \unskip~\citet{846859:19954865} was studied in American population, 56\% of population was aware that eating fresh fruits and vegetables will boost immunity, in present study, 84.5\% believed it and in another study by  \unskip~\citet{846859:19954858} concluded that 72.6\% of population will drink water and stay hydrated during H\ensuremath{_{1}}N\ensuremath{_{1}} pandemic, in the present study 75.5\% agreed to the statement. The study by \unskip~\citet{846859:19954864} concluded that 49.7\% aware, 50.3\% not aware of food sources of vitamin B\ensuremath{_{12}} in Saudi population, in present study, the orange colored vegetables contain beta carotene not vitamin B\ensuremath{_{12}} where 51.8\% are aware of the vitamin B\ensuremath{_{12}} food sources in Indian population, which is contradictory to the study. Most of the results of previous studies strongly agreed with the results of the present study.

The limitations of the present study is that the study was done in a small scale population of 110 participants and in a homogeneous population. The participant truthfulness is not tested, so the results may be biased. The options may not be available for the participants to answer the question, so minimal error may be present. 

Knowledge of natural dietary immunoboosters is a big boon in present day pandemic chaos as there is no cure to COVID 19 and also no vaccines. So, it is always better to stay safe and these natural dietary immunoboosters are very important which maintains and regulates our immunity.
    
\section{Conclusions}
From the survey results, it is clear that the majority of the sample population were aware of the fact that food supplements can regulate and boost natural immunity. Quite sarcastically it was to be scrutinised as to how far this knowledge is put to actual practice by the same population. It is also to be noted that in this present situation of `stay at home' due to the pandemic, how far practising these healthy dietary practices would be feasible to the people.
