Why are processed foods often considered unhealthy?

Processed foods are often considered unhealthy primarily because they may contain high levels of sodium, sugar, and unhealthy fats. These ingredients are commonly added during the processing to enhance flavor, extend shelf life, and improve texture, but they can contribute to various health issues when consumed in excess.

For instance, high sodium intake is associated with increased blood pressure, leading to cardiovascular problems, while excessive sugar consumption is linked to obesity, type 2 diabetes, and dental issues. Unhealthy fats, particularly trans fats and certain saturated fats, can raise bad cholesterol levels, further increasing the risk of heart disease.

In contrast, options focused on fiber, caloric content, or essential nutrients do not capture the fundamental concern with processed foods. Processed foods can vary widely in their fiber content, caloric density, and nutrient profile, making those factors less definitive in assessing their healthfulness.
