The Mediterranean diet regularly ranks at or near the top of expert reviews of eating patterns. Unlike many diets, it doesn’t cut out food groups, count points or require special products. It’s a pattern based on how people traditionally ate in countries such as Greece, southern Italy and Spain — and it has a substantial body of research behind it.
What it looks like
Eat plenty of:
- Vegetables and fruit
- Whole grains — oats, brown rice, whole-wheat bread, barley
- Beans, lentils and chickpeas
- Nuts and seeds
- Extra-virgin olive oil as the main fat
- Herbs and spices
Eat regularly:
- Fish and seafood, ideally at least twice a week
- Yogurt and cheese in moderate amounts
- Eggs and poultry in moderation
Eat less often:
- Red and processed meat
- Sweets and refined grains
- Ultra-processed foods
The traditional pattern also includes meals shared with others, unhurried eating and daily movement — aspects that are easy to overlook but may matter.
What the research shows
Heart health
The PREDIMED trial in Spain randomly assigned around 7,500 people at high cardiovascular risk to a Mediterranean diet supplemented with extra-virgin olive oil or nuts, or to a reduced-fat control diet. The Mediterranean groups had roughly 30% fewer major cardiovascular events — heart attacks, strokes and cardiovascular deaths. The original 2013 paper was retracted and republished in 2018 after problems with randomisation at some sites were identified; the reanalysis reached similar conclusions.
Longevity in women
A 2024 study in JAMA Network Open followed more than 25,000 initially healthy women in the US for up to 25 years. Women with the highest adherence to a Mediterranean-style diet had about 23% lower risk of death from any cause than those with the lowest adherence, with lower risk of both cancer and cardiovascular death. Researchers linked part of the benefit to lower inflammation, better insulin sensitivity and healthier body weight.
Other outcomes
Mediterranean-style eating has also been associated with lower risk of type 2 diabetes, better blood sugar control, and slower cognitive decline in some studies. Evidence for effects on menopause symptoms specifically is limited, though some observational studies link plant-rich diets with fewer hot flashes.
As with most nutrition research, much of the evidence is observational, so it shows associations rather than proof of cause. But the consistency across many populations, plus trial evidence for heart outcomes, makes it one of the best-supported dietary patterns.
Why it suits midlife
Several features line up with the needs of women after 40:
- Fiber from plants and whole grains supports gut health, cholesterol and blood sugar.
- Unsaturated fats from olive oil, nuts and fish help counter the rise in LDL cholesterol after menopause.
- Plant proteins and fish support muscle when combined with enough total protein.
- Calcium from yogurt and cheese, plus leafy greens, supports bone health.
Making it practical
You don’t need to cook Greek food every night. Some easy shifts:
- Swap your cooking fat to extra-virgin olive oil.
- Add a portion of beans or lentils to soups, salads and sauces several times a week.
- Make vegetables half the plate at lunch and dinner.
- Snack on nuts instead of crisps or biscuits.
- Have fish twice a week — canned salmon and sardines count.
- Treat red meat as a side rather than the centrepiece.
What about wine?
Traditional descriptions of the Mediterranean diet include moderate red wine. Newer evidence suggests there’s no level of alcohol that improves health, and alcohol raises breast cancer risk even at low intakes. If you don’t drink, there’s no reason to start — the benefits of the Mediterranean pattern come from the food.
The bottom line
The Mediterranean diet works less like a diet and more like a set of defaults: more plants, better fats, fewer processed foods. That flexibility is probably why people can stick with it — and sticking with it is where the benefits come from.
