The Claim
In Korean adults, adherence to a high-quality plant-based diet, defined as being in the top 40% of the healthy plant-based diet index (hPDI), is the single most protective lifestyle factor against type 2 diabetes, as evidenced by the strongest attenuation of protective effect when excluded from the composite score (hazard ratio = 0.42 compared to 0.44 for the full score).
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People in Korea who eat a lot of healthy plant foods like vegetables, beans, and whole grains are less likely to get type 2 diabetes than others—and this way of eating is the biggest protective factor compared to other lifestyle choices.

What the research says
1 studyThe study shows that people who live healthily — including eating good plant foods — have much lower diabetes risk. But it doesn’t prove that eating plants is more important than the other healthy habits like exercise or not smoking.
