Why have manufact ured food portions increased?

Manufactured food portions have increased primarily due to consumer demand for convenience and value, leading companies to offer larger sizes at competitive prices. Additionally, marketing strategies often promote larger portions as a better deal, encouraging bulk purchases. Changes in dining habits, such as the rise of fast food and ready-to-eat meals, have also contributed to this trend, as consumers seek quick and satisfying options. Consequently, these factors have combined to normalize larger serving sizes in the food industry.
