Foreword I wish to ignore what I try not to know, but I write what I do not wish to ignore. During 1974, when I was being medically examined before my travel on IAEA Fellowship to Italy, the physician forewarned me to balance my diet and advised me to eat less chapatis and avoid red meat as a precautionary measure. This was the first warning to look after my food and my late wife assisted and supported me fully on it. During 1974-1994, I was fully involved in agricultural research and development professionally in India and abroad, but personally I had to be careful about my diet and I was fully involved in producing food rather than on utilization of food. Suddenly, it took a turn in 1994 when I was appointed as Special Advisor on Food Security and was assigned by the FAO to formulate and launch the Special Programme for Food Security worldwide, particularly in Low-income Food Deficit Countries. This made me to update myself more on food availability, sustainability, accessibility and quality and safety, in order to mitigate hunger and malnutrition and to develop healthy human resources. At the dawn of the millennium, i.e. 2000, the PNASF was established to promote agricultural education, research and development with focus on food and nutrition security. Since then the PNASF has organised “International Conference on Vegetables” with the theme “Vegetables for Sustainable Food and Nutritional Security” (2002), FAO/PNASF “International Workshop for Asian Countries on Urban and Peri-urban Agriculture” (2005), “International Conference on Horticulture” with the theme “Horticulture for Livelihood Security and Economic Growth” (2009) and FAO/PNASF “Regional Workshop on Strengthening Urban and Peri-urban Agriculture towards Resilient Food System in Asia” (UPAFSA-2013). With the experience and knowledge gained, the PNASF and The Team members recognized that for the development and sustainability of valuable human resources, the basics of human civilization-food, agriculture and humanity, are to be realised in the true sense. The understanding, practice and result utilization have to play their role in complete integration for the benefit of humankind. v

It is difficult to ascertain which came first, food or human being. It is the same situation as chicken and egg where we lack evidence to indicate which came first on earth. It does not matter which came first but we know for sure that human being needs food and he or she needs everyday and throughout his or her life. In other words, a human being cannot survive without food indicating permanent unbreakable bondage between food and human being. It supports the basics of human civilization-food, agriculture and humanity.

1.    I deem it a singular honour to deliver Dr. Sen Memorial Lecture. Dr. Sen, who was both an administrator and a visionary, was instrumental for:

SYNOPSIS Food is an essential element without which human being cannot survive. We need it for our maintenance and growth everyday and through the longevity of our life. As we understand food, it is a bunch of essential elements which is essentially needed for the engine of human body to run non-stop. The understanding of food is much required by masses who consume it every day. The present paper attempts to describe the knowledge on food, feeling on food by consumers, prevailing food, hunger and malnutrition, healthy food and studies required on consumable foods.

SYNOPSIS We lag in nutritional awareness. The therapeutic values of plant foods, such as vegetables, fruits, grains, legumes, nuts, seeds, herbs, spices and other foods like dairy products, fluids and meats are to be brought to light. The values of important nutrients, may lead to the basis for nutritional education lacking at present. There is need to bring awareness and add to the knowledge of the younger generation. A food is something that provides nutrients. Nutrients are substances that provide: energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.

SYNOPSIS The availability of food is of paramount importance without which it is hard for human beings to survive. The recognized way of making food available is to produce but it is also equally important that food produced is utilized well without loss of edible food materials. The paper discusses on unused food, under- utilized food within and across countries, and puts emphasis on utilization and handling of food. In perspective, the paper highlights the steps to be taken up to save and utilize the food already produced.

SYNOPSIS In all probability the ancient farmer’s market originated on the streets of villages and later on, on the streets of towns. The street food survived through decades and centuries and now it has assumed its new role in fulfilling the readymade food demand of the working people of mega cities. The street food has now more relevance to the growing urban population. With the lapse of time and migration people to the cities, the business and activities of street food got expanded in qualitative and quantitative terms worldwide.

SYNOPSIS With the change of time, and the progressive development in life-style, the menu of food has undergone significant changes in communities, countries, regions and worldwide. This is influenced by the travel, migration of the people, and enhancement of the socio-economic status among the masses.

SYNOPSIS Nature produces plants with healing properties. Hundreds of phytochemicals and antioxidants have been identified in various food plants. Many plants or plant parts are eaten as food. There are several plant species which are cultivated for food, and many have several distinct cultivars. Seeds of plants are a good source of food for animals, including humans, because they contain the nutrients necessary for the plant’s initial growth, including many healthful fats, such as Omega fats. In fact, the majority of foods consumed by human beings are seed-based foods.

SYNOPSIS Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal or fish origin. Plant foods are the most abundant sources of nutrition on earth. Only plants contain powerful substances called phytochemicals, which protect us from cancer, heart disease, and an array of other serious illnesses.

SYNOPSIS Many plants or plant parts are eaten as food. In addition to essential vitamins, minerals, and fibers, plant foods contain phytochemicals and antioxidants, which actively provide protection against diseases. Several studies carried out all over the world have demonstrated the protective values of fruits. Fruits are the ripened ovaries of plants, including the seeds within. Many plants have evolved fruits that are attractive as a food source to animals, so that animals will eat the fruits and excrete the seeds some distance away.

SYNOPSIS Animal source foods (ASF) include any food item that comes from an animal source such as meat, milk, fish, eggs, cheese and yogurt. Many individuals do not consume ASF or consume little ASF by either personal choice or necessity as ASF may not be accessible or available to these people. Animals are used as food either directly or indirectly by the products they produce. Animal source foods (ASF) include any food item that comes from an animal source such as meat, milk, fish, eggs, cheese and yogurt.

SYNOPSIS Fish has now become an important animal protein for mankind. It is a rich source of essential amino acids, vitamins and minerals. Fish meat is easily digestible compared to other animal meat and has a higher Protein Efficiency Ratio when compared to casein, the milk protein. Fish oils like body oils of fishes like sardine, mackeral, anchoviella, herring, salmon etc. are the richest source for Omega-3 long chain poly unsaturate fatty acid like Eicos- pentanoic acid (EPA) and Docosahexaenoic acid (DHA) having therapeutical applications for man. A number of fishery products and by-products like squalene, chitin, chitosan, oyster meat, mussel meat, shark bones etc.

SYNOPSIS Flavor is the sensory impression of a food or other substance, and is determined mainly by the chemical senses of taste and smell. The flavor of the food, as such, can be altered with natural or artificial flavorings which affect these senses. Smell is the main determinant of a food item’s flavor. While the taste of food is limited to sweet, sour, bitter, salty, umami (savory), pungent or piquant, and metallic – the seven basic tastes – the smells of a food are potentially limitless.

SYNOPSIS Vegetables are essential for well-balanced diet since they supply phytonutriceuticals. About 3 billion people in the world are malnourished due to imbalanced diets. Regular consumption of a vegetable rich diet has undeniable effects on health since they have been strongly associated with improvement of gastrointestinal health, good vision, and reduced risk of heart disease, stroke, chronic diseases such as diabetes, and some forms of cancer.

SYNOPSIS There is an increasing awareness about quality of food among consumers all over the world. Organically produced food is considered to be nutritionally superior, but the available information is not conclusive.

SYNOPSIS There have been conflicting practices, recommendations regarding a healthy diet in human beings. Unscientific food habits are limitation to good health and active life. Because of various social, cultural, religious and economic factors human beings in the same climatic conditions and living situations, have been practicing different food habits leading to many health problems. What to eat, how much to eat and when to eat are not clear with the masses. This paper attempts to throw light on these aspects.

SYNOPSIS Human health is defined as a state of physical, mental, physiological and social well being. It is also considered as a state of body and mind, where there is a balance of body humors or secretions. The paper introduces the readers to common diseases caused through various agents like deficiency disorders, food and water, air-borne, vector, viruses, and life-styles. It also describes healthy food, health management, food management, and healthy life style.

Note: With my personal experience, I have learnt many lessons during the course of my journey of life. The reader should ponder over it and prepare own food profile and menu for the benefit of maintaining good health. My paper does not provide any prescription but provides illustration of my experiences only, which may be of some use in knowledge and practice of food. The medical and health experts need to be consulted as appropriate.

Synopsis If the human being was born first, he or she needed food immediately to survive. Thereafter, human beings continued to need food and continued to eat food throughout his or her life. Hence, the relationship between human being and food is permanent and the requirement of food for the human being to be alive is everlasting. The paper provides the background, definition of right to food, and adequate food, historical events, legal perspectives, operational guidelines, and advances in its application and derives conclusion.

SYNOPSIS Inspite of the fact that governments in various food summits and conferences have made commitments on food and nutrition security, presently more than a billion people are suffering from hunger and malnutrition worldwide. The food and nutrition policies need to be revisited and updated to address both man-made food scarcities and natural disasters of present and future to mitigate hunger and malnutrition.

On different occasions I have expressed my views on hunger and food security. Here are some of the views published earlier. 1. Food Security bill: Why it is an opportunity lost Several years ago I and Dr M S Swaminathan were speaking at a conference on hunger at Rome. Also speaking at one of the sessions was the Brazilian Minister for Zero Hunger Programme, the dream programme of ex-President LuizInácio Lula da Silva. After he had listened to us, he sat down with us to know of how India was battling hunger, specially the way India was managing its food self-sufficiency and the massive food procurement programme.

SYNOPSIS Urban and rural agriculture are different entities in terms of stakeholder involvement and enabling environment for farming but they are dialectically interlinked in providing food and nutrition security of any country. Urban agriculture is more suitable on the production of nutritious crops, while rural agriculture’s first priority is to produce more food from staple. Attaining nutrition security is more complex than it is previously thought. However, while existing systems of production should continue at field levels by developing more nutritionally rich cropping patterns, its integration with farmers’ farming systems remains more important.

Synopsis Food safety has become increasingly important with globalization due to various factors such as increased volume and diversity of trade in foods, greater public demand for health protection, changing hazards e.g., resistant microbes, more sophisticated methods for detection of hazards, changes in production and consumption pattern, etc. Food safety contributes significantly to food security as unsafe and poor quality food leads to illnesses as well as food wastage. This leads to a strong need to emphasize not only on availability of food but also ensure that the same is safe.

SYNOPSIS Food security is a complex issue, linked to availability and access to food, malnutrition in the population, economic development, environment, and local and global trade. Malnutrition hinders healthy growth and proper development of the human immune system affecting neurological and cognitive development especially in children.

SYNOPSIS India has been conspicuous as one of the most malnourished nations, as every child out of two is malnourished. Moreover, the levels of under nourishment is substantially high among tribal communities. The present investigation has been made to examine the levels of food insecurity at the micro level in four regions identified in the tribal dominated areas of Maharashtra on the basis of macro level indicators. A comparison of food insecurity between the two communities reveals a high incidence of food insecurity among the tribal as compared to that of non-tribal. The nutritional status of tribal children is much lower than that of their non-tribal counterparts.

SYNOPSIS Food and nutritional challenges continue to be tackled in East and Southern African countries. Prevailing rates of high malnutrition among children and often in adults in vulnerable geographical locations do suggest the need for appropriate interventions. Of several global nutrition interventions during the 1980s, successful implementation of nutrition programmes in Tanzania, Uganda, Malawi and Ethiopia have established strategies / approaches that are promising.  In Tanzania, the Iringa nutrition programme (WHO/UNICEF Joint Nutrition Support Programme) was implemented during 1983-1988.

SYNOPSIS After the break-up of the Soviet Union in 1992, the countries of Central Asia and the Caucasus (CAC) began making the transition from controlled to market economies. All of the countries have programs for economic and social development as well as food security. Over the last decade, the regional population increased 11%, from 72 million in 2002 to 79 million in 2012. Agricultural production has increased throughout the region. For example, vegetable production per decade has nearly doubled due to an increase in the area of the crops grown and to increased yields, and was more than 19 million t in 2011.

The present publication has highlighted the issues on different aspects of food sector expressed by very distinguished authors. The issues have been discussed and illustrated how we conceive food as an item, what and how much food is known to consumers, what are common food sources, the relationship between food and health, food and nutrition security programmes in different regions of the world and how do we perceive food and nutrition policy challenges?
