Summary:

The present prospective study examined the association between adherence to the Japanese diet and risk of all-cause and cause-specific mortality in a large, middle-aged Japanese cohort.
Diet was assessed using 8-item Japanese Diet Index score (0 to 8).
It was reported that individuals with the highest Japanese Diet Index score had a reduction of all-cause mortality by 14% and cardiovascular mortality by 11% in comparison the lowest Japanese Diet Index score group.
They concluded that adhering to a Japanese diet was associated with a decreased risk of all-cause and CVD mortality among adults living in multiple areas across Japan.

Discussion:

However, it is important to note that dietary intake was assessed at only one time point, therefore variations in dietary habits were not considered.
Also, although the researchers adjusted for many confounding factors, residual confounding including socioeconomic status can not be ruled out.

Question:

Do you think these findings will be reproducible other populations? What would be the challenges in following a Japanese diet in your country?
