Tourism, Health Promoting Food Domain and Technology Applications: Individual’s Genes Reservoir, Environmental Change and Food in Natural Health Context

Tourism has attracted so many customers from all over the globe that it has emerged as one of the key revenue generating industries in many countries. The key features which govern the customer influx in tourism industry prevailing in a given region include historical places; natural landscapes for natural sightseeing, hiking, mountaineering, sailing, or experiencing unusual geographical or geological phenomena; etc. which are publicized through effective marketing campaigns. Many people travel to developed countries to experience the taste of modern living, whereas others travel to enjoy the ancient cultural civilization, customs or cultural diversity, food folks, for attending festivals, exhibitions and for shopping clothing, handicrafts, jewelry etc. particularly the locally originated ones. The key factors that are kept under consideration while chalking out the tourism plans include cost, duration of trip, mode of traveling, and above all health and safety concerns. In recent years, the use of technology has magnified the tourism experience while making it hassle-free. Many countries which are rich in natural and historical heritage fail to attract tourists merely because they are not considered as safe to stay or have health concerns due to any prevailing illness outbreak. Travelling puts human body under stress that in turns makes it more prone to catch contagious diseases while being in journey or reaching on destination. Water, air, and food are the key vectors for transmission of germs (microorganisms) causing diseases. People are vaccinated and are given health advices before starting a trip for tourism. Spread of COVID-19, across the globe has halted economical activities which are the prime source to generate money for tourism that people use while sparing their time from their heavy professional life schedule. During Covid 19 Pandemic it has become a challenge to sustain economic activities and traveling while protecting people from illnesses. This piece of work covers basic information on a few cultural features and health-related issues including those which can occur during traveling while suggesting diets, many of them on having regular use prevent consumers from many diseases due to their prophylactic and therapeutic potentials, besides presenting a general scheme for cooking methods evolved in Indian subcontinent. Use of the suggested diets for journey can decrease the risk of acquiring illness during journey, making it safer and more enjoyable, whereas certain food preparations (desi food or their derivatives) are particularly proven supportive in conferring protection against COVID-19 virus illness and facilitate its cure besides offering their general prophylactic role. The hypothetical model, also based on use of diets and food preparations with integrated use of technology, is presented at the end of this chapter for providing safer and cost-effective option for tourism in relatively unexplored global regions present in Asia.
