Reacción a "Diet improvement at age 45 can extend life by two to three years, says study"

This study analyses the association between different dietary patterns and longevity. It is not a novel study. Much research has been done on this topic, and it is already known that healthy diets, such as the Mediterranean diet, contribute to a longer life expectancy. The most important thing today is that we can have a disease-free life expectancy, meaning that older people are healthy, do not have diseases, and do not consume high levels of medication. A healthy diet contributes to this, as do physical activity, healthy sleep, not smoking, and other healthy lifestyle choices.

The article reinforces what we already knew about the subject. It is not an experimental study that would provide a higher level of evidence. The advantage is that the sample size studied from the UK Biobank is large.
