The Dietary Guidelines for Americans include a "Healthy Mediterranean-Style Dietary Pattern" as one healthy option [1]. In a large Harvard study of nearly 48,000 men, the pattern was not linked to the risk of advanced prostate cancer, but among men already diagnosed it was linked to lower death from all causes [2].
What's on the plate
| Eat often | Eat moderately | Eat less |
|---|---|---|
| Vegetables, fruit | Fish and seafood (2+ times a week) | Red and processed meat |
| Beans, lentils, chickpeas | Poultry, eggs | Sugary drinks and sweets |
| Whole grains | Yogurt and cheese | Refined grains |
| Nuts, seeds, olive oil |
What the research in men shows
The Health Professionals Follow-up Study tracked 47,867 men from 1986 to 2010 [2]:
- A higher Mediterranean diet score was not associated with the risk of advanced or lethal prostate cancer.
- Among 4,538 men diagnosed with prostate cancer that hadn't spread, the diet after diagnosis was not linked to prostate cancer death, but closer adherence was linked to a 22% lower risk of death from any cause (hazard ratio 0.78).
These are observational findings. They suggest the pattern is a sensible overall choice, not a prostate treatment. NCI does not list any diet as a proven way to prevent prostate cancer [3].
A sample day
- Breakfast: oats with walnuts and berries, or shakshuka.
- Lunch: chickpea, tomato and cucumber salad with olive oil.
- Dinner: baked salmon with lemon and dill, roasted vegetables, barley.
- Snack: fruit and a small handful of nuts.
Good olive oil makes the pattern easy to stick with: this Colavita extra-virgin olive oil is a good everyday bottle.
