This book is a compilation of such onset of adolescence and children brings with it many profound changes. The growth rate speeds up dramatically. This growth spurt occurs due to the activity of hormones that affect every organ of the body and this makes healthy eating very important. The nutrient needs rise throughout childhood, peak in adolescence and then level off or even diminish as the teenager becomes an adult. The saying "You are what you eat" seems to be proven true. We eat different kinds of food such as dal, chapatti, bread, rice, vegetables, milk, lassie, etc. All these different kinds of food provide us with nutrients to keep us healthy and active. It is important to know what food to eat in order to stay healthy. The science of food and nutrients and their action on our health is called Nutrition. Nutrition and health, in fact, are two sides of the same coin. They are, therefore, inseparable. Health depends to a large extent on nutrition, and nutrition depends on the food intake. So food is the most important single factor for health and fitness. According to World Health Organization (WHO) "Health is the state of complete physical, emotional, and social well-being, not merely the absence of diseases or infirmity." This definition has remained unchanged since 1948. All of us want to maintain positive health, a perfect blend of physical, social and mental. Taking adequate amounts of essential nutrients in our diet is necessary to maintain positive health. Physical health is probably the most easily understood aspect. Mental health can be defined as a state of emotional and psychological well-being in which an individual is able to use her or his cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life. We hope that after reading the book on food and nutrition in human science you will understand how to live a healthy life.
