It would be ideal to feed oneself by eating, but for this to happen one must have food awareness. Nutrition is a voluntary act and therefore food education can be decisive in choosing one’s own food; nutrition is an involuntary act constituted by a series of physiological processes by which our body is programmed. History, culture, traditions and habits influence our food choices by determining the nutritional status, so being aware and knowing how to choose your own food becomes essential to guarantee the body the nutrients it needs for its correct functioning in the various stages of life. Food contains nutrients, substances that we need to live in good health: carbohydrates, proteins, lipids, vitamins, mineral salts and water. Vitamins and mineral salts are micronutrients (the body needs low amounts), while proteins, lipids or fats, and carbohydrates or carbohydrates are macronutrients (the quantities we need are greater). The human body uses micro and macronutrients to perform the following functions: plastic or builder; energy, regulatory or protective. A healthy and correct diet guarantees optimal growth and development, preserving the state of health, reducing the risk of contracting disorders and pathologies typical of incorrect nutrition. Three words must always be kept in mind: moderation, variety, balance. So we learn to eat not to satisfy the appetite, neglecting what we bring to the mouth, but being aware that food becomes an integral part of us.
