Processed foods tend to have a negative impact on health and fitness due to their high content of added sugars, unhealthy fats, and sodium. These ingredients can lead to weight gain, increased inflammation, and a higher risk of chronic diseases such as diabetes and heart disease. Furthermore, processed foods are often lower in essential nutrients and fiber, leading to poor dietary quality. Reducing the consumption of processed foods in favor of whole, nutrient-dense options can improve overall health and enhance fitness outcomes.
