Élelemforrás, or food source, refers to any organism, substance, or material that provides nourishment for living beings. In the context of human nutrition, food sources are categorized into macronutrients and micronutrients. Macronutrients include carbohydrates, proteins, and fats, which provide energy and essential building blocks for the body. Micronutrients, such as vitamins and minerals, are required in smaller quantities but are crucial for various physiological functions.

Food sources can be derived from various origins, including plants, animals, and fungi. Plant-based food sources are abundant and diverse, ranging from grains and vegetables to fruits and nuts. Animal-based food sources include meat, dairy products, and eggs. Fungi-based food sources, such as mushrooms, are also consumed by some cultures.

The quality and nutritional value of food sources can vary significantly. Factors such as soil quality, growing conditions, and processing methods can influence the nutrient content of plant-based food sources. Similarly, the diet and living conditions of animals can affect the nutritional profile of animal-based food sources.

In recent years, there has been a growing interest in sustainable and ethical food sources. This includes a focus on locally sourced, organic, and minimally processed foods, as well as a shift towards plant-based diets and reduced meat consumption. Additionally, there is a recognition of the importance of food security and ensuring that everyone has access to safe, nutritious, and sufficient food.
