Food additives can significantly affect the nutritional profile of processed foods. They are often used to enhance flavor, texture, or shelf life, but may also contribute empty calories and unhealthy substances, such as excess sugar, sodium, or unhealthy fats. Some additives can have adverse health effects, leading to increased caloric intake and a higher risk of obesity and chronic diseases. Understanding food labels and the potential risks associated with these additives is crucial for making healthier dietary choices and maintaining overall nutritional quality.
