Whole foods differ from processed foods primarily in their nutritional value and retention of natural nutrients. Whole foods are minimally altered and include fruits, vegetables, whole grains, nuts, and seeds. These foods retain their natural structure and are rich in essential vitamins, minerals, and fiber, promoting overall health. In contrast, processed foods are often high in added sugars, unhealthy fats, and preservatives, which can lead to various health issues. Focusing on whole foods supports better dietary habits and overall wellness, while limiting processed foods can reduce the risk of chronic diseases.
