From the study you cited: "Under the same assumptions, the 12% increase caused by switching to organic fruits and vegetables would correspond to an increase in life expectancy of, on average, 17 days for women and 25 days for men." This is 1) all based on a very tenuous model, not on a study of actual health outcomes ("The calculations behind these estimates depend on estimates of the relative risks of disease incidences according to fruit and vegetable consumption, most of which are known only with substantial uncertainty (Veerman et al., 2006).") 2) assumes a linear response (if a 1% increase in vitamins increases life expectancy by X, a 10% increase will increaes it by 10X), which also seems dubious 3) assumes that the input data about the nutritiousness of organic food is correct. And it's still a tiny effect. The life expectancy at birth for men in the Netherlands (the source of the model) is 81 years, or 29565 days, so it's a claimed 0.08% increase in life expectancy. Moreover, if organic food had a large effect on health we would expect today's rich kids to be substantially healthier than those of my generation, who ate Wonder Bread and Jif, but I have seen no such evidence. But then I am deeply skeptical of nutrition science in general.
