Current life circumstances allow a long lasting life and so, the group of elderly people is growing constantly. Unfortunately, aging and chronic diseases are closely related. An important factor contributing to the development of chronic diseases such as cardiovascular diseases (CVD) and cancer is diet. We studied whether a healthy diet followed later in life (age 60 years and above) prevents the occurrence of chronic diseases and increase life expectancy in elderly people from Europe and the United States. The results showed that greater adherence to a healthy diet based on globally applicable dietary guidelines (WHO and WCRF/AICR) decreased the risk of premature death, death from CVD and total cancer risk in a large proportion of elderly participants from Europe and the United States. Eating according to the recommendations extended the life span by 2 years and the risk for the diagnosis of cancer was postponed by about 1.5 years, while adhering to a healthy diet. These results show that one is never too old to eat healthy.
