The effect of processed foods on nutritional health is largely negative, as these products often contain high levels of sugars, salts, and unhealthy fats. Regular consumption can lead to increased risks of chronic health issues, such as obesity, diabetes, and heart disease. Processed foods also tend to be low in nutrients and fiber, which are essential for overall health. Learning to read food labels and reducing intake of highly processed items can promote better nutritional choices and enhance long-term health outcomes.
