Food sources refer to the various origins from which we obtain our food. These can include plants, animals, and fungi. Common plant-based food sources are fruits, vegetables, grains, and legumes, while animal-based sources include meat, dairy, and eggs. Each type of food source provides different nutrients essential for human health. In addition to natural food sources, processed foods are also available, which are made from raw ingredients. These can include snacks, canned goods, and frozen meals. Understanding food sources helps individuals make informed choices about their diets and nutrition, contributing to overall well-being.
