"We began our analyses with the expectation that aculturation might be a risk factor for poor cognitive function in late life and that traditional Japanese lifestyle, culture and diet might be protective.

As this finding was explored it became evident that the relationship with oriental diet could be attributed almost entirely to a single food item: tofu."
