There is no food that stops ageing. There are eating patterns that can support health, and there is a difference between a plausible theory and a trial measuring clinical outcomes. A Mediterranean-style, plant-rich diet is useful to discuss because researchers have tested it in people, not just in cells or advertisements.
What PREDIMED actually measured
The corrected 2018 PREDIMED report involved 7,447 adults aged 55–80 at high cardiovascular risk, without cardiovascular disease at enrolment. Participants received advice for a Mediterranean diet with extra-virgin olive oil, a Mediterranean diet with nuts, or a control diet with advice to reduce fat. Follow-up lasted a median 4.8 years.
Major cardiovascular events occurred in 3.8% of the olive-oil group, 3.4% of the nut group and 4.4% of the control group. Adjusted hazard ratios were 0.69 and 0.72 for the two Mediterranean groups. Those relative estimates should not be confused with 31 or 28 percentage points fewer events. The absolute group proportions help show the size of the difference.
Why we cite the corrected paper
The original 2013 report was withdrawn after randomisation irregularities were identified. The 2018 analysis addressed those problems, including sensitivity analyses. Participants received education and supplied foods, which may affect how readily the results transfer to an unsupported diet change. Public funding and food-industry contributions or author relationships also require consideration. Calling the study completely unbiased would be misleading.
What this can look like on your plate
- Build meals around vegetables, fruit, beans, lentils and whole grains.
- Include suitable sources of protein, rather than treating all protein foods as interchangeable.
- Use nuts and unsaturated fats where appropriate, with attention to allergies and overall needs.
- Choose changes you enjoy and can afford, not a long list of forbidden foods.
This trial does not establish that everyone must become vegan, that a particular oil cures disease or that eating well replaces prescribed treatment. Kidney disease, gastrointestinal conditions, food allergies and medication can change what is appropriate. A restrictive plan that compromises protein or energy intake may undermine strength rather than protect it.
Nutrition support at Zhen
Nutrition coaching can help translate broad evidence into repeatable meals and habits. The aim is to support your health and activity goals, not to sell a detox or promise disease reversal. More specialist dietary needs may require a registered dietitian or your medical team. A personalised discussion is more useful than assuming that the same menu fits everyone.
Your next step in Onchan
At Zhen Wellness, 5c Village Walk, Onchan, the starting point is your body and your priorities, not a package chosen before an assessment. The £97 Longevity MOT is a standalone 60-minute appointment covering history and goals, pain mapping where relevant, posture, body composition and mobility. It helps inform practical next steps; it is not a medical diagnosis or a test that predicts how long you will live. Any later programme is separate, with options and costs discussed before you decide.
Evidence and scope
Sources checked on 12 October 2026. The research below examines specific interventions and populations, not Zhen programmes. No study is free of possible bias, and an average trial result is not an individual guarantee. This is general education, not personal medical advice. Advice for adults should not be applied unchanged to children; younger clients need age-appropriate support and consent arrangements. Seek professional advice for new or worsening symptoms, existing medical conditions or changes to exercise and nutrition that could affect treatment. Do not stop prescribed medication.
