Human nutrition is a complex, multifaceted scientific domain indicating how substances in foods provide essential nourishment for the maintenance of life. It is a process by which substances in food are transformed into body tissues and provide energy for the full range of physical and mental activities that make up human life.
The study of human nutrition is interdisciplinary in character, involving not only physiology, biochemistry, and molecular biology but also fields such as psychology and anthropology, which explore the influence of attitudes, beliefs, preferences, and cultural traditions on food choices.
Human nutrition further touches on economics and political science as the world community recognizes and responds to the suffering and death caused by malnutrition. The ultimate goal of nutritional science is to promote optimal health and reduce the risk of chronic diseases such as cardiovascular disease and cancer as well as to prevent classic nutritional deficiency diseases such as kwashiorkor , pellagra etc. Numerous disorders ranging from protein energy malnutrition to the specific micronutrient deficiency prevailed in Pakistan. Nutritional deficiencies have resulted in growth retardation, mental disorders and various types of physical disabilities. Beside, the incidences of cardiovascular diseases, diabetes, cancer, obesity, hypertension with kidney and liver problems are increasing day by day due to unsafe and poor quality diets. This alarming situation demands to cure diseases with food, realizing the importance of human nutrition in daily life and emergencies like earthquake, drought, famine and man-made disasters.
