La nutrición es un tema fundamental para la salud y el bienestar de todos los seres vivos. Aunque many of us think about alimentación (feeding) as simply eating, nutrition goes beyond that. It involves the processes by which our bodies take in and process food to sustain life, grow, and maintain overall health. This article explores the meaning and definition of nutrition, its importance, and how it impacts our daily lives.
¿Qué es la Nutrición?
Nutrición refers to the scientific study of the nutrients in food and how they affect the body. It encompasses the processes by which organisms ingest, digest, absorb, and utilize nutrients from their diet. These nutrients, such as proteins, carbohydrates, fats, vitamins, and minerals, are essential for energy production, growth, and the repair of body tissues.
Historically, ancient civilizations recognized the importance of diet in maintaining health, even without the scientific understanding we have today. For example, Hippocrates, the father of medicine, emphasized the role of diet in health and disease.
