Life span is increasing very marginally. You are probably referring to life expectancy, which has been increasing.

Life span is how old a human is capable of living. This number has not changed much in hundreds or thousands of years. Life expectancy is how many humans reach any specific age. Life expectancy increases are primarily driven by decreases in infant deaths (which bring down the averages), and secondarily by better diagnosis and treatments of disease in older humans.

In any case, the existence of better medicine is not predicated on the development or consumption of ultra processed foods. There is no “same package”.
