The Claim
Between 1979 and 1992, the annual percentage decline in ischemic heart disease mortality among men aged 30–49 years in Tokyo and Osaka prefectures was 0.05%, and this rate was similar to the decline observed across all age groups in the rest of Japan.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
From 1979 to 1992, the rate at which deaths from ischemic heart disease decreased each year among men aged 30–49 in Tokyo and Osaka was 0.05%, which was the same as the rate of decline for all age groups in the rest of Japan.

When people eat less saturated fat, their blood cholesterol drops, which causes less fatty buildup in the heart arteries. This keeps blood flowing better to the heart muscle and prevents heart attacks.
What the research says
1 studyIn Tokyo and Osaka, heart disease deaths among young men barely went down from 1979 to 1992, while in the rest of Japan, they dropped steadily across all ages — and the study proves this exact pattern with real numbers.
