What type of foods are generally classified as "processed foods"?

Packaged snacks and fast food are generally classified as processed foods because they undergo various manufacturing or preparation techniques that significantly alter their natural state. This includes the addition of preservatives, flavor enhancers, and other ingredients that extend shelf life or enhance palatability. Processed foods are typically characterized by their convenience and ready-to-eat nature, but they may also contain higher levels of sodium, sugar, and unhealthy fats compared to whole foods.

In contrast, options such as fruit and nuts, whole grains and legumes, and fresh vegetables are typically considered whole or minimally processed foods. These are closer to their natural state with little to no alteration, preserving their nutrient content and health benefits. Whole foods generally contain fewer additives and are associated with a healthier diet, while processed foods are often linked to negative health outcomes when consumed in excess. Understanding this classification helps in making informed dietary choices and recognizing the impact of food processing on overall nutrition.
