The diet plan lowered the chances of early death in almost 70,000 people by 18 per cent, a study claimed.
Their risk of cardiovascular death was lowered by 20 per cent.
There was also a 13 per cent lower risk of cancer death.
People that smoke were even more likely to benefit from the anti-inflammatory diet, the scientists said.
Researcher Dr Joanna Kaluza, from Warsaw University, said: “Our dose-response analysis showed that even partial adherence to the anti-inflammatory diet may provide a health benefit.”
