A "superfood" is defined as a nutrient-rich food considered to be especially beneficial for health and well-being. These foods are typically high in antioxidants, vitamins, and minerals that provide various health benefits, such as reducing inflammation, improving heart health, and enhancing immune function. While the term is often used in marketing, it is essential to understand that no single food can guarantee health benefits. A balanced diet rich in various nutrient-dense foods is crucial for achieving overall health and longevity.
