Processed (refined) foods are products that have been altered from their original form through methods like cooking, canning, freezing, or adding preservatives. This process often enhances flavor, extends shelf life, and improves convenience. Common examples include white bread, sugary cereals, and canned vegetables. While processed foods can be convenient, they often contain added sugars, unhealthy fats, and sodium, which may contribute to health issues when consumed in excess. It's important to read labels and choose options that are less processed, such as whole grains and fresh fruits, to maintain a balanced diet and overall health.
