A year of a supported Mediterranean diet slightly lowered systolic pressure

Among people who completed the year and had valid data, systolic pressure fell modestly. Diastolic pressure showed no firm difference.

How we make these readings

The study, in plain language

Following a diet also depends on the support received. In a trial called NU-AGE, people aged 65 to 79 at five European centers were randomized: some received personalized guidance and food to adopt a Mediterranean pattern adapted to this stage of life, while others followed their country’s nutrition guidelines.

After a year, among people with data for the final analysis, systolic pressure was modestly lower with the intervention. Diastolic pressure showed no firm difference. In a smaller group at one center, one measure of arterial stiffness improved and another did not clearly change. Results varied by which aspect of pressure or arteries was measured, and stiffness was measured in only some participants. A sex-specific analysis found a favorable systolic difference among men but not women. Participants were not blinded to assignment.

The key idea

After a year of a supported Mediterranean diet, systolic pressure was slightly lower among people with valid final-analysis data. Other measures showed no firm difference.

Something to think about

When a diet works in a study, how much is due to the food and how much to the support for following it? Here, support included guidance and food, not just a list.
