Whole grains (like rye, oats, and whole wheat) have a strong history in traditional Scandinavian cuisine, but as in other regions, the food landscape is changing and reﬁned grains have replaced some traditional foods. To see how eating whole grains relates to mortality, researchers analyzed the diets of over 120,000 people in Denmark, Norway, and Sweden. The scientists found that those who ate the most whole grains had signiﬁcantly lower risk of death from all causes. When analyzing individual whole grains, the researchers found signiﬁcantly lower mortality rates in those who ate the most whole grain breakfast cereals, whole grain bread, oats, rye (only statistically signiﬁcant for men), and whole wheat. These ﬁndings support existing evidence that whole grains may contribute to longevity.
