Although food traditions vary from country to country, many traditional healthy diets are rooted in wholesome plant foods like fruits, vegetables, and whole grains. In a study of 1404 people who had been diagnosed with colorectal cancer at least six years prior, researchers analyzed their eating patterns based on how closely they aligned with a Mediterranean diet (fruits, vegetables, grains, unsaturated fats, legumes, moderate alcohol) and a healthy Nordic diet (ﬁsh, root vegetables, whole grain bread and oatmeal, apples, pears, cabbage). Those who most closely followed a Mediterranean diet were signiﬁcantly less likely to die during the study period than those not following a Mediterranean diet. Similarly, each 1-point increase on the Modiﬁed Mediterranean Diet Score or the Healthy Nordic Food Index was linked with improved survival.
