Olive oil, vegetables, beans, whole grains, nuts and fish, with modest dairy and little red meat. Best known for its cardiovascular outcome trials.
LDL-C effect in studiesSmall: about 0 to 6 mg/dL lower LDL-C on average; strong data for fewer heart attacks and strokes
This section shares information about dietary patterns and the research on them. lipid.site doesn't recommend any particular diet, and nothing here is medical or nutrition advice for you. Talk with your clinician or a registered dietitian before making big changes, especially if you have diabetes, kidney disease, an eating-disorder history, are pregnant or breastfeeding, or take blood thinners or other daily medicines. Food changes can work alongside cholesterol medicines; they usually don't replace a medicine your clinician prescribed.
Eat more
- Extra-virgin olive oil as the main fat
- Vegetables, fruit, beans and lentils
- Whole grains
- Nuts and seeds
- Fish and seafood, at least twice a week
Eat less
- Red and processed meat

- Lunch: Greek salad with chickpeas, olive oil and whole-grain pita
- Dinner: baked fish with tomatoes, olives and greens, plus farro or white beans
Who it may suit
People who want a flexible, enjoyable pattern with outcome evidence, omnivores and pescatarians, and people who eat out often.
Things to watch
- Olive oil and nuts are calorie dense; portions matter if weight is a goal.
- Cheese and processed meats creep in on many 'Mediterranean' menus.
- Alcohol (red wine) is optional and is not needed for benefit; skip it with liver disease, pregnancy, some medicines or a history of alcohol problems.
- If LDL-C doesn't move much, that matches the trial data; rechecking labs shows your response.
Tell me more
Mediterranean diets have strong outcome data: in PREDIMED (primary prevention, re-analyzed in 2018) a Mediterranean diet with extra olive oil or nuts reduced major cardiovascular events by about 30% versus a reduced-fat diet, and in CORDIOPREV (people with coronary heart disease) it reduced major events by roughly 25 to 28% over 7 years versus a low-fat diet. The direct effect on LDL-C is small: a Cochrane review found about 6 mg/dL (0.15 mmol/L) lower LDL-C versus other diets (moderate certainty). Benefit likely comes through several pathways beyond LDL-C. Adding Portfolio foods or more fiber increases the LDL-C effect.
Evidence strength: strong means several good trials agree; moderate means trials agree but are small, short or varied; limited means a few small trials or mostly indirect evidence. LDL-C numbers are averages from studies. Your own result can be larger, smaller or zero.
- Cost: moderate. Olive oil, nuts and fish cost more; beans and canned fish keep it affordable.
- Effort: moderate home cooking; plenty of simple sheet-pan and salad meals.
- Eating out: easy at Greek, Italian, Lebanese and Turkish restaurants.
- Easy to make pescatarian or vegetarian.
People enjoy it and stick with it, though some report their LDL-C barely moved until they added more fiber or cut cheese.

Your results will vary
Diet affects LDL-C differently from person to person. Two people on the same plan can see very different results, and genetics (including familial hypercholesterolemia and Lp(a)) set a floor that food alone may not move. The only way to know what a change does for you is to recheck your labs, usually after 6 to 12 weeks of sticking with it. Log your results here to see the trend.
Medicines still matter
If your clinician has recommended a statin or other medicine, changing your diet works together with it. Many people need both to reach their goal.
