Human health refers to the total state of social, physical as well as mental well-being rather than just the absence of illness, infirmity or disease. Nutrients are components found in food that drive biological activity and are therefore necessary for human health. Good nutrition is required for a person to develop physically and maintain proper health. Nutrients can be classified as carbohydrates, proteins, minerals, lipids as well as vitamins, which are helpful in performing essential functions of the body. They are helpful in growth and maintenance of body parts like teeth, bone and muscle, as well as the generation of energy. Nutrition also has a significant impact on the safety, metabolism and effectiveness of a drug. The interactions between food and drugs are studied within pharmacology under the sub-discipline of nutritional pharmacology. It also studies the effect of different micronutrients on the pharmacodynamics and pharmacokinetics of drugs. This book explores all the important aspects of pharmacology and nutrition in the modern day. It aims to shed light on the role of nutrition and pharmacology in human health. Researchers and students in this field will be assisted by this book.
