A "superfood" is a term used to describe foods that are particularly nutrient-dense and beneficial for health. These foods are often rich in vitamins, minerals, antioxidants, and other compounds that can help improve overall well-being. Common examples of superfoods include blueberries, kale, and quinoa, which are known for their high nutritional value. While the term "superfood" is popular in health and wellness discussions, it is not a scientific classification. Many foods can contribute to a healthy diet, and no single food can provide all the nutrients the body needs. A balanced diet that includes a variety of foods is essential for optimal health.
