Showing examples that refute people hypotheses is so valuable.
Reminds me of the Israeli paradox, Israel has very low saturated fat intake but high heart disease rates. This information on it's own completely disproves any claim that high saturated fat could be the sole cause of heart disease. There must be either an underlying or parallel mechanism that explains Israel.
Any "sole cause" claim about health/diet stuff seems highly suspect at best, I can scarcely imagine anything such a claim could be true for. You can't even say that cigarettes are the sole cause of lung cancer; the link between the two is incontrovertible but there are still many other ways to get lung cancer (asbestos, radon, bad luck, etc..)
Maybe a result of an higher than usual endogamy in the population.
In biology is called effect of the founder, and explain why Jews of german origin have a higher incidence of several recessive genetic diseases than other groups. Many of the survivors moved probably in mass to Israel after the war.
