Superfoods play a significant role in modern nutrition due to their nutrient density and health benefits. These foods, such as berries, quinoa, and kale, are rich in antioxidants, vitamins, and minerals that support overall health and combat chronic diseases. They are often praised for their ability to enhance energy levels, improve digestion, and boost the immune system. While "superfood" is a marketing term, including a variety of these nutrient-rich foods in a balanced diet can lead to improved well-being and lower the risk of illness, making them popular choices for health enthusiasts.
