Additionally, industrial boilers require less management and minimize dependence on electricity, making them an economical and efficient option for industries.

OPERATING MECHANISM OF A FLOUR MACHINE
The flour grinding machine operates using blade cutting, high-speed air impact, and a two-layer destruction function that integrates collision and particle sorting. The principle of operation involves the rotor generating high-speed airflow during blade cutting. As the material accelerates within the airflow, repeated impacts cause it to be destroyed in two layers simultaneously, enhancing the destruction rate. As airflow enters the classification chamber, the destruction process rotates at high speed, and the classification rotor generates centrifugal force. The viscous effect of the airflow creates centripetal force. When the centrifugal force on the particles exceeds the centripetal force, the coarse particles return to the destruction chamber, while fine particles are carried with the airflow to the powder collector for collection. There are three primary operating characteristics of the flour mill. First, the main shaft in the power system is sequentially equipped with bearing caps, radial ball bearings, bearing pads, and thrust ball bearings from top to bottom. Second, the grinding system consists of a spring, spring pad, inner grinding head, adjusting nut, and outer grinding head mounted on the spindle. Lastly, the separation system features a brush mounted on the spindle, with a tension spring above and an adjusting nut below the brush. The core principle of the flour grinding process is to reduce grains like wheat, corn, or rice into flour particles. Raw grains are introduced into the mill's hopper and then conveyed to the grinding chamber containing the grinding stones or rollers. As the grains pass through the chamber, the high-speed rotation of the stones or rollers generates friction that crushes, grinds, and pulverizes the grains into a coarse powder, which gradually becomes fine flour. Flour mills are equipped with adjustable settings to regulate the gap between the grinding stones or rollers, allowing for varying flour fineness. This ensures the production of flour suitable for different culinary needs, from coarse flours for rustic bread to fine flours for delicate pastries. The ground flour particles are then

Rice milling machines are crucial in the rice production industry, as they are used to remove the husk and bran layers from paddy, resulting in polished white rice. Various types of rice milling machines, such as hullers, whitening machines, polishers, and graders, are available, each designed for a specific function in the milling process. When selecting a rice milling machine, it's essential to consider factors such as capacity, efficiency, power consumption, and maintenance requirements. Additionally, the machine’s size should be aligned with the scale of rice production operations. By investing in the right machinery, producers can enhance overall efficiency and product quality, while reducing manual labor and processing time.
OVERVIEW OF RICE MILL MACHINERY
Rice mills are food-processing facilities where raw paddy is converted into rice. These mills use modern machinery to process the paddy harvested from fields, transforming it into the final product, rice. Various types of rice mill machines are utilized throughout the milling process to ensure efficient and effective production.
Applications of Rice Mill Machinery
Milling is one of the key steps in the production of rice. It is generally performed post the production of rice. The paddy produced industrially cannot be consumed in its natural forms. This is why paddy is processed post its production, by the process of milling. It removed in order to make it fit for human consumption.
Variants of Rice Mills
There are many types of rice mills, each tailored to specific processing needs and production capacities. Below is a list of machines used in rice mills:
• Single-Pass Rice Mills: These machines are designed for simpler rice milling operations. They typically perform the essential tasks of husking and whitening in a single pass.
• Multi-Pass Rice Mills: Ideal for large-scale operations, multi-pass mills carry out multiple milling stages. These stages include cleaning, husking,

The operation and maintenance of dehusking, dehulling, degerming, and drying equipment are crucial in ensuring the efficiency and longevity of these machines in grain and seed processing industries. These machines play a vital role in removing husks, hulls, and germs from grains, as well as reducing moisture content to enhance storage stability. Proper handling and regular maintenance not only improve performance but also reduce downtime and operational costs. Dehuskers are used to remove the outer husk from grains like paddy and millet. Their efficiency depends on factors such as roller pressure, feed rate, and machine alignment. Routine maintenance involves checking for wear and tear on rollers, adjusting pressure settings, and ensuring that all moving parts are well-lubricated. Similarly, dehullers remove the outer shell of seeds and grains, requiring careful calibration to avoid excessive grain breakage. Blade sharpness, motor performance, and sieve integrity should be regularly inspected to ensure optimal functioning. Degermers are employed to separate the germ from the endosperm in grains like maize. This process enhances the shelf life of processed products and improves their quality. Regular maintenance of degermers involves inspecting the abrasion plates, checking the feed rate, and ensuring that airflow mechanisms are clear of obstructions. Any malfunction can lead to uneven separation, affecting the final product quality. Dryers are essential in reducing the moisture content of grains to prevent microbial growth and spoilage. They require proper temperature control, uniform airflow, and regular cleaning of heat exchangers and drying chambers. Overheating or under-drying can compromise the grain quality and lead to storage losses. Timely inspections of sensors, air ducts, and burner efficiency help maintain effective drying operations. A well-planned operation and maintenance routine ensures these machines function optimally, increasing productivity and product quality while reducing energy consumption and repair costs.

Fruits and vegetables are more perishable and generally have a higher value compared to cereals, making them very important in terms of minimizing waste and improving employability in the food industry. The losses in fruits and vegetables are significant, but through effective post-harvest processing, these losses can be reduced, and surplus produce can be better utilized. This processing involves a variety of techniques that prepare fruits and vegetables for conversion into processed foods. The food preservation and processing industry has evolved from being a luxury to an essential sector, playing a crucial role in conserving and enhancing the utilization of fruits and vegetables. To prevent waste during peak seasons and ensure availability during off-seasons, modern methods of storage and processing are necessary. These techniques allow for both large-scale and small-scale processing, extending the shelf life of produce for better distribution. The ultimate goal of food processing is to apply systematic techniques to preserve, process, package, store, and distribute food in a way that ensures a steady supply of diverse and nutritious food options, thereby improving food intake and nutritional standards, particularly during periods of low availability.
For effective preservation and processing, key prerequisites include cleaning, grading, and sorting the produce based on its maturity level. This ensures that only the highest quality fruits and vegetables are used in the processing chain, maintaining food safety, nutritional value, and consumer acceptability throughout the year.
CLEANING OF AGRICULTURAL COMMODITIES
Blanching is a unit operation used in food processing to remove contaminating materials from food and prepare the surface for further processing. In vegetable processing, blanching serves the additional purpose of cleaning the product. This process involves briefly exposing the food to heat, typically by immersing it in hot water or steam, which helps to remove dirt, enzymes, and microbial contamination. By doing so, blanching not only improves the quality of the food but also prevents microbial growth during storage or delays in processing. This early removal of contaminants ensures that the remaining bulk of food is preserved and remains safe for consumption throughout its shelf life.

Agro processing involves a diverse range of unit operations aimed at converting raw agricultural products into value-added goods. These processes serve to enhance the shelf life, quality, and overall appeal of agricultural commodities while also boosting their nutritional content and market value. The unit operations employed in Agro processing are determined by the specific characteristics of the product and the desired outcome. Common steps include cleaning, sorting, peeling, grinding, and milling. Preservation methods such as blanching, fermentation, drying, and freezing play a crucial role in preparing products for consumption or further manufacturing. Furthermore, operations like extrusion, canning, juicing, and packaging are essential for producing a variety of processed food items, while proper storage and warehousing ensure the long-term availability and sustainability of these goods. Each unit operation is designed to contribute toward creating high-quality, market-ready products, minimizing waste, and ensuring optimal utilization of raw materials. By combining these processes effectively, Agro processing maximizes the potential of agricultural resources and strengthens the overall food industry.
OVERVIEW OF MATERIAL HANDLING
Materials handling encompasses a broad spectrum of activities, including mechanical harvesting on farms, transportation of live animals, refrigerated transport of perishable goods, and pneumatic conveying of flour from rail cargo to bakery storage facilities. It is important to minimize product losses during these operations while maintaining the quality of raw materials, such as preserving vitamin content and physical appearance, ensuring sanitary conditions, reducing bacterial growth, and optimizing the timing of transfers to avoid delays that could compromise both the economy and product quality. The journey of agricultural produce from farms to processing areas often results in significant transformations. For instance, grapes are transported via tractors, trucks, or trailers to juice plants or wineries, where they are graded, washed, and processed further. However, there are limitations on the size of transport vehicles and the duration fruits and vegetables can be held. Since these are living, respiring products, prolonged storage can increase batch temperatures to levels that encourage spoilage.

Application of Climate-Smart Agriculture

Agricultural production systems are expected to change in response to climate change and ensure food security in different countries. Climate variability may further affect the agricultural production in future. To meet such challenges, there are many options to reduce the negative impacts of climate change on agricultural systems, make them resilient to climate change, and reduce emissions. Many technologies and practices can increase crop yields, farm income, and input-use efficiency, and may reduce GHG emissions (Khatri Chhetri et al. 2017). Climate-smart agriculture (CSA) is suggested to address the adverse effects of climate change and ensure food security. It is intended to achieve the three objectives of ensuring productivity, adapting and building resilience and reducing emission of GHG.

Climate-smart Agriculture Practices and Indicators

Considering the three pillars of climate-smart agriculture such as productivity, adaptation and mitigation, different technologies and practices have been evolved.

The CSA practices are grouped under soil and land management, water management, crop management, livestock management, forestry, fishery & aquaculture and energy management. The World Bank Group (2016) has suggested broad indicators of CSA practices (Table 7.1; Chapter 7)

Need for climate-smart agriculture strategy

Climate change has long-lasting and potentially detrimental consequences on the agriculture sector. Changes in weather events cause perturbations across agricultural ecosystems and have impact on farm productivity. Adopting the climate-smart agriculture approach has thus, become inevitable in order to build resilience in agriculture systems and cope up with climate change. With a view to implementing climate-smart agricultural practices to ensure climate resilience, certain broad strategies have to be adopted. The CSA approach is designed to identify and operationalize sustainable agricultural development within the explicit parameters of climate change (Climate Smart Agriculture Sourcebook.FAO.2013). It integrates the three dimensions of sustainable development (economic, social and environmental) by jointly addressing food security and climate challenges.

Introduction on Climate Smart Agriculture (CSA)

Extreme weather conditions like rainstorms, high wind pressures, high temperatures, flood and drought situations have profound influence on agriculture. Climate and agriculture are strongly interrelated universal processes and thus variations in climate influence agricultural activities (IPCC, 2007). The effects of climate change are seen in form of global warming, unseasonal and excess rainfall, and frequent natural calamities which affects agricultural production. At the same time emission of GHG to the atmosphere is a major source of climate change. The impact of climate change on crop yield, dairy and other livestock production including fishery will be felt in reduced production and consumption. Climate change will effect in additional increase in prices for main agricultural food crops such as rice, wheat, corn and soybeans (IFPRI, 2009).

Climatic factors like increase in temperature, carbon dioxide (CO₂) concentration, moisture, and other factors directly or indirectly affect agriculture, which have been elaborately dealt in previous chapters. Climate change causes weather variability that may result in low production, hike in price of agricultural commodities including food grains, vegetables, fruits, meat, egg and milk. It is now realised that climate resilient agriculture (CRA) will be imperative to reduce the vulnerability of agriculture to the climate change.

Agriculture and Food Security

Food security refers to a situation when people gain physical and access to enough food to meet the dietary requirements for a healthy life for all times. A household can have food security when all the members lead a hunger free life. It is estimated that nearly 800 million people in the world go to bed hungry every night. Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life (World Food Summit, 1996). This definition gives rise to four dimensions of food security: availability of food, accessibility (economically and physically), utilization (the way it is used and assimilated by the human body) and stability of these three dimensions.

Climate and Agriculture

Soil, climate and water are three basic requirements of a crop to be grown in a particular region. Climate affects the temperature trends, seasons, length of the growing season, amount of sunlight and the seasonality of sunlight etc. A change in climate may cause recurrent droughts, floods and weather extremities that would affect the agricultural production, human livelihoods, health and biodiversity. The relationship between agriculture and climate is complex as it is dependent on climate and also plays a contributing role in emission of greenhouse gas (GHG). Greenhouse gases include carbon dioxide, nitrous oxide, methane, chlorofluorocarbons (CFCs), hydro-chlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), per fluorocarbons (PFCs) etc. , which play a significant role in climate change.

Climatic Factors and Crop Growth

Crop growth depends on internal and external factors. Internal factors are mostly genetic or hereditary factors which include high yielding ability, resistance to lodging, tolerance to adverse conditions such as drought, flood and salinity, tolerance to insect pests and diseases, and grain quality. The external factors include climate, edaphic, biotic, physiographic and socio-economic factors.

Modern agriculture requires certain precise information on pattern of rainfall, temperature, occurrence of drought and flood etc. for formulating required strategy for crop production. It also requires knowledge about agro-climatic conditions of the region for deciding a planned cropping pattern. Therefore climatic classification and delineation of agro-climatic zones would be imperative for a country or state.

Weather and climate have profound influence on agriculture of a region. There are some differences between these two terms. Weather describes the state of the lower atmosphere of a place with respect to temperature, precipitation, wind direction, wind speed, humidity, cloudiness and pressure etc. over a short period of time. The short term variations over minutes to days are indicated as weather of a location. It says whether the atmosphere is hot or cold, rainy or dry, sunny or cloudy, still or cyclonic and so on usually for period of 24 hours. The weather may vary from place to place and from time to time due to difference in temperature, cloudiness, humidity, rain and other events of atmosphere. It may be sunny at one locality, but rainy at another locality.

Technical and Economic Challenges in Advanced Packaging The implementation of advanced packaging technologies comes with a range of challenges. Technically, developing materials that are both highly effective and environmentally friendly is a complex task. Packaging must not only protect products and ensure their safety, but also minimize its ecological footprint.

13.1 Biopolymer-Based Coatings with Antimicrobial Properties 13.1.1 Understanding Biopolymer-Based Coatings Biopolymer-based coatings are a game-changer in food packaging, offering natural, sustainable solutions for food safety. These coatings, derived from renewable sources, like polysaccharides (e.g., chitosan, starch, cellulose), proteins (casein, gelatin), and lipids (wax, shellac), have proven to be biodegradable and consumer-friendly alternatives to synthetic polymers. 13.1.2 Antimicrobial Properties and How They Work • Antimicrobial coatings are crucial in slowing down spoilage and extending the shelf life of perishable foods. They work by disrupting cell membranes, inhibiting cell processes, and creating oxidative stress in microbes. This is achieved through natural antimicrobials like essential oils (e.g., oregano, thyme, clove), plant extracts, and organic acids; inorganic agents like silver nanoparticles, zinc oxide, and titanium dioxide; and microbial-derived substances like nisin, lysozyme, and bacteriocins (Yu, Z et al ., 2022)

12.1 Active Packaging: Types, Mechanisms, and Applications • Antimicrobial Packaging: This type contains substances such as organic acids, enzymes, or metals like silver nanoparticles to prevent microbial growth, thus prolonging shelf life ( Ma, Q et al .2021) • Oxygen Scavengers: These absorb oxygen to minimize oxidation and spoilage, often used in snacks, baked goods, and meats. • Moisture Control: Packaging features absorbent materials or humidity regulating films to keep moisture levels optimal, particularly in fresh produce. • Ethylene Scavengers: These helps slow down the ripening process in fruits and vegetables by reducing ethylene gas levels. • CO? Emitters: These generate carbon dioxide to inhibit microbial growth, particularly useful in certain food products (Yildirim et al., 2018) 12.2 Mechanis

Packaging machinery is a critical component in the food industry, enabling the efficient and consistent packaging of food products while maintaining safety, quality, and freshness. From automated filling and sealing systems to advanced inspection and labeling machines, packaging machinery plays a pivotal role in delivering food products to consumers in optimal condition. The machinery used in food packaging is designed to handle various product types, from solid and liquid foods to powders and granular items, each requiring specific handling, filling, and sealing techniques. In an industry where speed, hygiene, and precision are paramount, packaging machinery has evolved to include sophisticated features such as robotics, computer-controlled systems, and sensors that monitor critical parameters like weight, temperature, and fill levels. These innovations help manufacturers improve productivity, reduce waste, and ensure that food products meet regulatory standards and consumer expectations.

The packaging requirements for food products are as varied as the foods themselves, with each category necessitating unique materials and design considerations to ensure product quality, safety, and consumer satisfaction. Packaging serves as the first line of defense against environmental factors like moisture, light, oxygen, and microbial contamination, which can significantly impact food stability and shelf life. The role of packaging extends beyond mere protection; it also contributes to preserving texture, flavor, and nutritional value, making it a crucial factor in the overall success of a food product. Chapter 10 delves into the specialized needs of different food types—such as bread and bakery items, snacks, dairy products, coffee, and carbonated beverages—analyzing the packaging materials, structural designs, and technologies required to maintain product integrity. The food industry faces the complex challenge of balancing protective packaging with considerations for sustainability, consumer convenience, and regulatory compliance. This has led to the evolution of advanced

Permeability is a fundamental concept in food packaging, shaping the protective capabilities of packaging materials by determining the extent to which gases and vapors can move through them. This property plays a crucial role in preserving food freshness, safety, and quality by controlling the interaction between the food product and its surrounding environment. Understanding permeability is essential in designing packaging solutions tailored to the specific requirements of different food products, as improper permeability can lead to accelerated spoilage, nutrient degradation, and undesirable changes in texture and flavor. In this chapter, we explore the science of permeability in food packaging, breaking down its core principles, the behavior of different gases and vapors in various packaging materials, and the factors influencing permeability. Additionally, we examine how permeability impacts shelf life and consumer satisfaction, offering insights into selecting materials for specific food types. By understanding and manipulating permeability, food manufacturers can develop packaging that optimally balances protection and breathability, extending product shelf life and ensuring quality

Aseptic packaging is a specialized and advanced method used to extend the shelf life of perishable foods without the need for refrigeration. This technique involves sterilizing both the food product and the packaging material separately and then filling and sealing the product in a sterile environment. Aseptic packaging has transformed the food industry, allowing products such as dairy, juices, soups, and sauces to remain fresh and safe at room temperature for extended periods. The ability to maintain product quality, nutritional value, and safety while reducing reliance on cold storage has made aseptic packaging a preferred choice in both food manufacturing and distribution.

Food packaging now serves critical roles in preservation, safety, marketing, and sustainability, aligning with both global and regional standards that cater to a wide array of consumer needs. This chapter provides an overview of the importance of food packaging, discusses the current landscape in both global and Indian markets, identifies key trends and challenges, and explores packaging’s role in the modern food supply chain. Each section aims to illustrate how food packaging impacts food quality, longevity, and overall consumer satisfaction, highlighting the industry’s ongoing innovations and adaptations to regulatory and environmental concerns. 1.1 Definition and Significance of Food Packaging Definit

Therapeutic Aspects of Drug-nutrient Interactions
Drug-nutrient interactions are expressed as physical, chemical, and pathophysiological relationships between a drug and a nutrient. This reaction is multifactorial. The drug has the potential ability to interact with nutrients which may lead to a reduction or enhancement of therapeutic efficacy, nutritional risk, and drug toxicity. Even such interactions lead to the discontinuation of drug therapy. But these kinds of interactions vary from person to person. Infants and children are the most vulnerable group in this concern as they are in the developmental phase where there is a lack of proper drug-metabolizing enzymes and inefficient renal function. Generally, DNIs signify negative impacts on human health but sometimes these interactions work in a positive way by reducing irritation in the GI tract or by increasing the absorption of drugs. Proper updated knowledge about DNIs is important for the appliance of diet therapy simultaneously with drug therapy as both of these are important strategies to manage or treat public health issues (Table 10.1., Table 10.2.).

9.1. Introduction
The three basic need for human survival are- food, clothing and shelter. The requirement of food comes first. Human are omnivorous. They eat mainly natural foods. Before 5000 years ago, cereals were the main food for all civilization and then the complexity of life began to make appearing with the advent of industrialization, flourishing of industry and commerce. Unpolished grains were utilised at first, but in contemporary civilisation, we have begun to prepare them, which results in the loss of essential nutrients. The intake of meats, processed meals, and sugary goods has grown while the general intake of cereals has decreased. People now lack vital nutrients as a result of the departure from natural diets. People began to realise a few years ago that health is a significant concern in addition to flavour, convenience, and quality value. They have thus begun taking nutritional vitamin supplements to make up for the nutrients lost from processed meals. People are increasingly opting for natural nutraceuticals in capsules and tablets, a trend known as medicalization in nutrition, instead of relying on natural food items. Hippocrates emphasized the connection between food and medicine, stating that healthy foods has a strong therapeutic advantages. The ancient Indian medical system known as Ayurveda places a strong focus on the functioning of diet and nutraceuticals in both health and illness.
9.2. What are Nutraceuticals
Stephen De Felice, the founder and chief executive of the Foundation for Innovation in Medicine (FIM), first used the term “nutraceuticals” in 1989 to refer to the broad category of medicines and nutrition. Nutraceuticals are foods or dietary components that not only offer nourishment and energy but also significantly contribute to regulating and preserving the regular physiological processes that keep people healthy. Nutraceuticals included processed meals such as cereal-grains, soups or stews, genetically engineered foodstuffs, herbal items, nutritional supplements, and extracted nutrients. People are increasingly concerned about their healthy wellbeing these days. However, these include a hectic, sedentary lifestyle, unhealthy eating patterns, body image issues, and being afflicted by a number of illnesses. These are the factors driving the global nutraceutical market’s expansion and generating a lot of interest. Numerous health issues of the century, including cancer, type 2 diabetes, heart disease, inflammation, oxidative stress, constipation, and more, can be fought off with the use of these nutraceuticals. Overall, nutraceuticals bring an entirely novel phase in medical science and assist the food companies to promote more creative research strategies. (Dudeja and Gupta, 2017)).

8.1. Introduction
Micronutrients are vitamins, minerals, and nutraceuticals that do not provide energy and do not raise any sensation of hunger known as “hidden hunger” or “insensible hunger”. Hidden hunger that causes micronutrient deficiency affects 2 billion people globally. Due to the deficiency of micronutrients, different diseases are noted among public health professionals that reflect poor community nutrition. To overcome these deficiency-related diseases, one of the important approaches is food fortification. Food fortification is a public health policy to reduce the number of individuals, who suffer from micronutrient deficiencies within a population. Common examples include iodine-tagged common salt, vitamin A-containing oil, and iron-enriched rice all of which are examples of food fortification. In the agricultural field, food fortification (FF) and/or food enrichment (FE) is the most efficient strategy to overcome various micronutrient deficiencies by the addition of essential micronutrients (vitamins and minerals) to enhance the nutritional value of cultivated crops. According to World Health Organization (WHO) and Food and Agricultural Organization (FAO) of the United Nations (UN), “Food fortification” is defined as “the practice of deliberately increasing the content of an essential micronutrient, i.e., vitamins and minerals (including trace elements) in a food irrespective of whether the nutrients were originally in the food before processing or not, so as to improve the nutritional quality of the food supply and to provide a public health benefit with minimum risk to health” (Pant and Chinwan, 2014). “Fortificant” refers to the incorporation of substances in the food to provide micronutrients. “Micronutrients” refers to the important dietary components, including vitamins and minerals, that are required in very small amounts but are engaged in very critical roles in various body functions and disease prevention.

7.1. Introduction
Entrepreneurs serve as the catalysts for the introduction of innovative technologies and systems that ultimately lead to societal advancements. These innovations are linked to enhanced lifestyles, progressive thinking, morale, and bravery, along with an improved standard of living. National and global changes are greatly influenced by such kinds of social change. Joseph Schumpeter, an Australian famous economist, is referred to as the father of entrepreneurship. Dhirubhai Ambani was the most enterprising Indian entrepreneur. Jamsetji Tata set a bar for entrepreneurship development in India with the foundation of the Tata group. The father of entrepreneurship in India is Ratan Tata. In public health, nutrition-based entrepreneurship and self-employment are also another emerging topic nowadays. Several entrepreneurs are found in this field mostly due to the challenge of building a business and craving to control their destiny. Not only that, financial independence, personal satisfaction, relief from the frustration of working for someone else, and the opportunity to create the desired lifestyle. Nutrition entrepreneurship offers numerous business-related resources and provides services for social well-being. As for example, the transformation of raw food ingredients into consumable food products, entrepreneurship plays a key role in diversifying and commercializing agricultural products. It adds value of food, prolongs its shelf life, promotes the export of processed items, generates employment opportunities, boosts farmers’ earnings, and makes a significant contribution to the general development of rural areas. Health entrepreneurs like nutritionists, dietitians, physicians, and health counsellors run their practice and make it available for the client to listen to their problems and solve their problems through mental support, motivation, diet therapy, medication, and so on. As a result, the health burdens due to noncommunicable and communicable diseases are reduced.

6.1. Introduction
The best way to combat malnutrition globally among women and children have changed over the last few years keeping pace with the advancement of technology. Information and communication technologies (ICT) have become very important for solving the contemporary nutrition related issues because they provide a vast array of new communication capabilities. In addition to meeting society’s actual needs for ongoing health and nutrition care, ICTs are crucial for facilitating interactive, personalized nutrition communication. People can interact or communicate with others in different countries in real-time through instant messaging, video conferencing or voice over IP (internet protocol). Through social networking platforms like Facebook, Instagram, and others, people from all over the world can regularly converse and stay in touch. In the context of health communication, ICT is referred to as Interactive Health Communication (IHC), which is the exchange of health information and advice and support regarding health-related matters between a consumer, patient, caregiver, or professional using an electronic device or communication technology. Nutrition treatments are less expensive when face-to-face interaction is facilitated by electronic means. These are complementary factors that encourage nutrition communication in an information-age healthcare system, especially when combined with consumers’ growing desire to take charge of their own health. Customers can advantageously use information technology in this system to connect with health professionals and support groups, obtain absolutely relevant information, and take charge of their own health. The “global village,” which has been made possible by modern information and communication technology, allows people to interact with each other virtually as if they were neighbours. Because of this, ICT is frequently examined in relation to the ways that contemporary communication technologies influence society.

5.1. Introduction
The people of every nation would be healthier if they adopted healthier lifestyles. A Good nutrition, daily exercise and proper sleep are the base of healthy living. A healthy lifestyle denoted by fit, energetic and at minimize possibility for disease. According to WHO, Healthy living is a way of living that helps you enjoy more aspects of your life. It is a way of living that lowers the risk of being seriously ill or dying early. Health is not just about avoiding a disease or illness.
5.2. Concept of Health
According to WHO, Health is the state of complete physical, mental and social well being and not merely absence of disease or infirmity. The holistic approach of health is the individual’s health and lifestyle considering all four factors, physical, intellectual, emotional and social. It concern about the whole body and mind not just a part of the body and the symptoms of the problem. It will look at the lifestyle of the individual such as nutritional deficiencies, reason of stress and why there is a lack of good health and wellbeing. A holistic approach will engage the individual taking responsibility for their health and well-being. They do this by educating themselves and being active in maintaining and improving their health and well-being.
5.2.1. Positive Health
Positive Health is the scientific study of health assets. A “health asset” is a factor that construct stronger health, over and above risk factors for disease. Positive Health works to find which specific health assets produce longer, healthy life, and which health assets lower disease risk and health care costs. The aim is to strive for optimal health —beyond the mere absence of illness.

4.1. Introduction
The food is the main factor known to affect the health of an individual. By interference in the protein synthesis, function and metabolites and alteration in genome expression, the healthy condition must be altered to diseased condition. Side by side we can say that the dietary component directly or indirectly modulates the molecular fingerprint and understanding of which is dealt with nutrigenomics. So, by modulation of a particular gene for a specific disease by nutrition, we can prevent the specific disease and promote the health of a population. Consuming fruits and vegetables on a regular basis has been linked to better health outcomes and diminution of several chronic or life style linked diseases.
Concept of Nutritional Genomics
After completion of human genome sequencing, the unique term “Nutritional genomics” tends to replace the old term “Nutrient-gene interaction”. It has been stated that so many polymorphism can influence protein structure and function. There are several regulatory sites where nutrients can impact the flow of genetic information. The two components of the nutritional genomics field are nutrigenomics, which studies how dietary components interact with the genome to regulate changes in proteins and other metabolism, and nutrigenetics, which determines how dietary components affect genetic variations. (Farhud et al., 2010). Nutrients are as environmental influences can interact with genetic material. It is commonly known that DNA metabolism and repair require a range of dietary elements that serve as cofactors or substrates in metabolic pathways. However, little is known about how cofactors and/or micronutrient excess or deficiency affect the accuracy of DNA replication and repair (Caroline and Fenech, 2008). The response to a particular nutrient, which is determined by the individual genotype, must also be taken into consideration, even though the nutrients can influence the development of a particular phenotypic.

3.1. Introduction
Sports nutrition is one of the areas of nutrition that closely coordinates with human anatomy research and the science of sports. The application of nutrition science to a practical daily eating plan intended to optimise the performance of athletes in competitive events, speed up the healing and reconstruction process following intense physical activity, and supply the energy for physical activity is known as sports nutrition. It also seeks to promote wellness and general health. Nutrition is strongly connected to fitness, specifically whilst sports activities are involved. It is necessary to recognize the physiology of the workout on the way to recognizing the specific metabolic pathways that coexist in the course of sports activities practice (O’Donoghue, 2014). Three things are necessary for athletic success: genetic endowments, level of training, and nutrition. It is impossible to change one’s genetic makeup. The most efficient method for enhancing athletic performance is specialized exercise training, and any kind of workout regimen must include adequate nutrition. The dietary requirements of athletes and workout aficionados are different from those of physically inactive people due to variations in their calorie needs as well as macro- and micro- nutrient needs. To achieve peak athletic performance, it is crucial to investigate and evaluate the dietary requirements of athletes prior to, during, and following the contest (Cotugnae et al., 2005). Exercises that improve one’s heart health involve swimming, jogging, and climbing. Other exercises that improve one’s flexibility, power, and endurance of muscles involve stretching and hard training with resistance. For example, if someone decides to choose to lose excess fat and to do so, they would design a regular exercise routine that incorporates all of the above-mentioned elements, as well as choosing more nutritious foods in the diet to meet the higher demands to endeavors. Athletic performance requires sports-related abilities. These neuromotor skills, such as balancing, pace, power, durability, stamina, agility, and execution, are particular to sports.

2.1. Introduction
The present century is the century of oxidative stress (OS) that linked to several life-threatening disorders which predominantly affect public health as well as their nutritional status. Unhealthy lifestyle and eating pattern which is major concern for OS. The biological literature first used the phrase “oxidative stress (OS)” in 1970. OS can be defined as a state of imbalance condition between the high level of pro-oxidants and the low level of antioxidant scavenging capacity in the body. The normal oxidative process that occurs in cells is crucial for the existence of life and favours the death of a cell. Free radicals, which are unstable, can form when molecular oxygen breaks up into pairs. This unstable radical has a high level of reactivity and produces reactive molecular species like reactive oxygen species (ROS) and reactive nitrogen species (RNS). To resist the OS and to maintain the redox balance, cells have an inbuilt antioxidant defence capacity, comprising of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPOD) etc. But some pathogenic or environmental conditions may overpower this antioxidant defence system, allowing a portion of reactive oxygen and nitrogen species (RONS) to bypass degradation and create much more reactive radicals. Increased ROS and RNS affect redox balance and damage DNA, proteins, amino acids, and fats, causing alteration of structures as well as action of cells and tissues. This will ultimately produce several pathogenetic elements associated with clinical situations and leads to the development of human aging and numerous diseases. Several dietary components such as whole grains, nuts, fruits, and vegetables are excellent sources of antioxidative vitamins, minerals, nutraceuticals or phytoceuticals that shields the human body from the harmful oxidative injury by scavenging or destruction of free radicals and also by upregulation of endogenous antioxidant defence system. Thereby long-term and sustainable OS remedies can be performed.

1.1. Introduction
The terms ‘counselling’ and ‘health promotion’ complement each other when it becomes a matter of an individual’s health. Health promotion is a part of behavioural social science that aims to change the systemic strategies adopted by the individual or group or by the mass community for the betterment of their health which can be achieved by talk therapy known as counselling. In the 21st century, from childhood to adulthood, all people are in a ‘rat race’ for their careers and necessities, which is one of the main reasons for stress generation. Not only that, chemical substances consumed by different food ingredients as food additives, preservatives, etc. but also induce oxidative stress and damage the functional activity of cells, tissues, organs, and systems. This ‘stress’ is a major culprit not only for the deterioration of physical health but also psychological health. Such stress imposition in daily life impairs normal physiological functions, skills, performance, and productivity. Unhealthy food, life, and work styles are also linked to the onset of pathophysiological complications that counselling and health promotion are required to overcome. Besides this, for sportsmen, pregnant women, lactating mothers, and growing children, nutritional counselling and health promotion are indisputable. For disease prevention and early recovery from disease, dietary counselling plays an immense role.
1.2. Counselling
Counselling is an intermittent, interpersonal interviewing process where the counsellor gives advice or suggestions to the client but never gives any direction. Counsellors assist the client in thinking, analysing, and acting to improve their insight power. The counsellor focuses on both the positive and negative sides of a particular event and allows the client to think and rethink its acceptability and unacceptability.
