That's not a data point. That's a broad statement that generalizes about a population, and yes: It would be a good to see a source that indicates that an entire generation is "falling apart at the seams" either as a result of their preference for "fair trade free range organic" food or their avoidance of fat and sugar -- if, indeed, that is even true of the population in question.
It is a data point because it is the same family, similar genetics, similar upbringing, similar socioeconomic status. One generation ate crap and did okay. Another was more cautious, but to no avail. As to whether or not that diet is causal, I made no statement or suggestion. I don't even have an opinion on it. I am merely stating that, according to the science of the day, they did "the right thing", but the situation did not improve.
That's a data point.
