Energiaértékére

Energiaértékére translates from Hungarian to "energy value" or "caloric value" and refers to the amount of energy that a food or substance provides when consumed. This energy is typically measured in kilocalories (kcal) or kilojoules (kJ). The energy value of food is derived from its macronutrient content, primarily carbohydrates, fats, and proteins.

Carbohydrates and proteins each provide approximately 4 kilocalories per gram. Fats, on the other hand, are more energy-dense, offering about 9 kilocalories per gram. Alcohol also contributes energy, with approximately 7 kilocalories per gram. Water, vitamins, and minerals do not contain energy. Understanding the energy value of foods is crucial for managing dietary intake and maintaining a healthy weight. Nutritional labels on food packaging usually display the energy content per serving, allowing consumers to make informed choices. For example, a person aiming to lose weight might choose foods with lower energy values, while an athlete might require foods with higher energy values to meet their increased energy demands.
