A superfood refers to nutrient-rich foods considered beneficial for health and well-being. Examples include blueberries, known for their high antioxidant content; quinoa, a complete protein source; and kale, which is packed with vitamins and minerals. These foods are often associated with various health benefits, such as reduced risk of chronic diseases and improved overall health. While no food alone can cure ailments, incorporating superfoods into a balanced diet can be a valuable strategy for overall health enhancement.
