What I'm saying is that this purported food safety isn't manifesting itself through superior life expectancy, burden of disease or IQ measurements. Why do you think that is?

Because food safety is one of thousands of factors that affect life expectancy, burden of disease and IQ metrics?

So what do you think these other factors are?

For life expectancy - genetics, traffic safety, drug use, suicide rate, healthcare, how the data is categorized, etc, etc, etc
