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, canned vegetables, and frozen meals. While processed foods can be convenient, they may also contain added sugars, unhealthy fats, and sodium, which can impact health if consumed in excess. It's important to read labels and choose options that are lower in these additives. Whole foods, like fruits, vegetables, and whole grains, are generally considered healthier alternatives.
