How Much Olive Oil Per Day? What the Studies Actually Used
How much olive oil per day makes sense when one study mentions half a tablespoon and another asks people to use four? Those figures describe different research questions, diets and participants. They are not competing prescriptions. A spoonful on lunch may be enough to make olive oil a regular part of your meals; four tablespoons was a target inside a much broader Mediterranean diet trial. The EU's 20 g figure belongs to the conditions for a particular polyphenol health claim, not to a universal daily dose. This guide puts the amounts side by side, translates them into kitchen measures, and shows how to think about the calories and the fats you replace. Olive oil is a food, and the rest of your plate matters.

The Short Answer
- No study establishes one daily dose for everyone; a tablespoon is a useful kitchen measure, not a prescription.
- Guasch-Ferré and colleagues' 2022 observational study of 92,383 US adults found an association above 7 g daily, without proving causation.
- Estruch and colleagues' corrected 2018 PREDIMED trial of 7,447 high-risk adults advised at least four tablespoons within a Mediterranean diet, not as an isolated dose.
- The EU's 20 g condition belongs to a specific polyphenol claim for qualifying oil; our untested batch does not carry that claim.
- A tablespoon is roughly 13–14 g and 120 calories, so consider what other fat it replaces in a meal.
- Use our separate guides for choosing a daily bottle or for the experience of taking oil neat.
Start With the Unit: Tablespoons, Grams and Calories
A standard tablespoon holds 15 ml. For olive oil, that is approximately 13.5 g and around 120 calories; a teaspoon is approximately one third of it. These are useful conversions, not a promise that every free pour is exactly the same. Use a measuring spoon or a kitchen scale when you want to understand your usual amount. The British Heart Foundation's nutrition guidance likewise puts a tablespoon at about 120 calories and advises sensible amounts within a balanced diet.
Two tablespoons therefore add roughly 240 calories, and four roughly 480. The arithmetic matters because a tablespoon looks small in a bowl. It is easier to judge a dressing made with a measured spoon than a long pour directly from a bottle. The point is awareness, not treating every gram as a rule to obey.
What the Large US Cohorts Measured: More Than 7 g
In a 2022 Journal of the American College of Cardiology paper, Guasch-Ferré and colleagues followed 60,582 women and 31,801 men in two US prospective cohorts for up to 28 years. People reporting more than 7 g of olive oil a day—just over half a tablespoon—had lower all-cause mortality than those reporting rare or no use. Diet was estimated repeatedly by questionnaire, not assigned as a dose; unmeasured habits may still explain part of the association.
The same analysis modelled substitutions. Replacing 10 g per day of margarine, butter, mayonnaise or dairy fat with olive oil was associated with lower mortality; comparing olive oil with other vegetable oils combined did not show a significant difference. That is a useful distinction for the kitchen: the replacement may matter at least as much as the number on the spoon.
What PREDIMED Asked People to Eat: At Least Four Tablespoons
Estruch and colleagues' corrected 2018 New England Journal of Medicine report described a Spanish trial of 7,447 adults at high cardiovascular risk. One group received advice on a Mediterranean diet supplemented with extra virgin olive oil and was encouraged to consume at least four tablespoons daily. A second Mediterranean diet group received nuts, while a control group received advice to reduce fat. The olive oil group also changed its wider eating pattern; the trial did not randomise four tablespoons against one tablespoon while keeping everything else identical.
The original 2013 report was withdrawn and reanalysed after deviations from individual random assignment were found at some sites. The corrected report addresses those irregularities, but the trial still answers a question about dietary patterns in a particular high-risk Spanish population. It does not establish that everyone should add four tablespoons to the meals they already eat.
A Small Direct Comparison: Four Tablespoons Versus Less Than a Teaspoon
A different perspective comes from the Recipe for Heart Health trial by Krenek and colleagues, published in 2024 in the Journal of the American Heart Association. Forty adults at elevated cardiovascular risk followed two whole-food plant-based vegan diet phases for four weeks each, in random order: one included four tablespoons of uncooked extra virgin olive oil daily, the other less than a teaspoon. Both patterns improved several measured markers from their own baselines. The low-oil phase showed a more pronounced LDL-cholesterol reduction, with diet-order effects complicating the comparison.
Forty participants and short phases cannot settle long-term clinical outcomes. Nor is an oil-light vegan diet the same comparator as a Mediterranean diet rich in butter or other saturated fats. The trial is still a useful challenge to the idea that more olive oil must always produce more benefit, whatever it displaces.
What the EU's 20 g Figure Actually Means
Commission Regulation (EU) No 432/2012 permits the wording “Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress” only for an oil containing at least 5 mg of hydroxytyrosol and its derivatives per 20 g of olive oil. To carry that claim, information must also tell consumers that the effect is obtained with a daily intake of 20 g. Twenty grams is around one and a half tablespoons.
That figure is a condition attached to a specific claim on a qualifying oil. It is not an official recommendation that every person needs 20 g, and 20 g of any olive oil does not automatically qualify. We do not have a batch certificate establishing hydroxytyrosol content for Sidr & Stone's oil, so we do not apply the claim to our bottle. The distinction between a legal claim condition and a personal eating target is essential.
Does One Tablespoon a Day Have a Special Effect?
One tablespoon is a convenient measure, not a switch that turns a biological effect on. The Guasch-Ferré 2022 cohorts found an association above 7 g daily, but their 92,383 participants were observed rather than assigned to exactly one tablespoon, and residual confounding remains possible. PREDIMED's corrected 2018 trial involved a much larger target inside a Mediterranean diet, but its 7,447 high-risk participants were not assigned to different olive-oil doses. The two designs cannot identify a universal one-tablespoon threshold.
A measured tablespoon can still be a sensible starting point if you enjoy the flavour and want to replace another added fat at a meal. Whether that fits depends on the rest of your diet, energy needs and preferences. Someone already using olive oil to cook and dress food may be eating it regularly without creating a separate daily ritual.
How Much Is Too Much?
There is no universal upper limit. Four tablespoons provide roughly 480 calories, a substantial addition to unchanged meals. The British Heart Foundation recommends considering olive oil alongside the rest of the diet and using it to replace fats high in saturated fat, with portion size in view. A larger amount may fit one person's eating pattern and not another's; it is not a contest to reach the highest number in a paper.
If a large pour makes a meal uncomfortable, reduce it and use the oil across food instead. People managing a medical condition or a prescribed diet should ask a qualified clinician or dietitian for individual advice. Our guide to drinking olive oil covers the separate question of taking it neat; no shot is required by these studies.
Put the Amount on a Plate, Not a Calendar
Think in meals. A teaspoon can dress a plate of vegetables; a tablespoon can make a vinaigrette for a salad or finish beans and grains; oil used in cooking also counts toward the day's total. Measure the oil going into a shared dish and divide by the portions if you need an approximate per-person amount. This is more informative than measuring a spoonful at breakfast while overlooking the oil in dinner.
The substitution matters. In Guasch-Ferré and colleagues' 2022 observational cohorts of 92,383 adults, replacing specified solid or dairy fats with olive oil was associated with lower mortality, while the comparison with other vegetable oils combined was not significant; observational modelling cannot prove a personal outcome. In practice, a dressing in place of a buttery sauce is a clearer swap than adding a second fat to the same meal. For a broader cooking context, see our heart-health evidence guide.
Choose the Bottle for Daily Use
Amount and quality are separate decisions. The EU's 20 g polyphenol claim requires a qualifying measured composition, not just the words “extra virgin” on the label. For general cooking, flavour and freshness also determine whether you will actually use an oil on vegetables, pulses and salads. Our daily-use bottle guide goes into the choice of oil for someone who prefers it neat; the research on amounts does not require that method.
We would rather have you use an amount that fits a good meal than chase an unsupported number. A bottle should make ordinary food more enjoyable, and its product page should state what is known about origin, processing and the current batch. For a fuller buying checklist, see our guide to choosing quality olive oil.
Why Sidr & Stone
Sidr & Stone's current olive oil is an extra virgin food from our own single-estate farm near Marrakech. The points below describe its sourcing and packaging; they are not a claim that our untested batch satisfies the EU polyphenol threshold or reproduces a study outcome.
- Sidr & Stone sources from one family-owned single estate on the plains outside Marrakech, without blending origins.
- The grove is rain-fed and organically grown without synthetic fertilisers, pesticides or herbicides; certification is in progress, as disclosed below.
- The oil comes from a limited single-harvest batch, with fruit picked when it is ready and cold-pressed within hours of harvest.
- It is unfiltered extra virgin olive oil, 100% natural with one ingredient and no additives; natural sediment may settle.
- The 500 ml dark glass with gold label helps shield the oil from light.
- Sidr & Stone commits 10% of profits to charity, with fulfilment in the UK, EU, and US.
We do not have a published batch polyphenol, acidity or peroxide figure and do not attach an EU health claim to this oil. The single estate and method are concrete reasons to consider the bottle; your own meals determine how much you use.
Frequently Asked Questions
How much olive oil per day should I eat?
There is no universal study-proven dose. A measured tablespoon is a practical amount to try in food while considering the fats it replaces and your overall energy intake; individual dietary advice belongs with a qualified professional.
Why do studies give different daily amounts?
They ask different questions. Guasch-Ferré and colleagues' 2022 observational cohorts of 92,383 US adults described an association above 7 g daily but could not establish causation; Estruch and colleagues' corrected 2018 PREDIMED trial assigned 7,447 high-risk adults to whole diet patterns, not isolated oil doses.
How do I measure 20 g of olive oil?
It is roughly one and a half standard tablespoons, although a kitchen scale is more accurate. The EU's 20 g figure is tied to the conditions for a qualified polyphenol claim, and measuring that amount alone does not establish that an oil meets the chemical threshold.
Is four tablespoons better than one?
Not necessarily. Krenek and colleagues' 2024 four-week crossover trial in 40 adults compared four tablespoons with less than a teaspoon within a whole-food vegan diet; its short duration, small size and diet-order effects limit what it says about long-term outcomes.
Does Sidr & Stone's oil meet the EU polyphenol claim?
We have not published a batch certificate for hydroxytyrosol and its derivatives. The EU claim requires at least 5 mg per 20 g of the qualifying oil, so we do not claim that our bottle meets it.
Do I need to drink olive oil to reach a daily amount?
No. Oil in a dressing, dip or cooked meal counts as food intake. Our separate guide examines taking it neat, while the named studies here concern dietary intake or whole eating patterns rather than a required shot.
Where can I buy the Marrakech oil?
Our cold-pressed organic Marrakech olive oil is on pre-order, with estimated shipping from November 2026. Check the product page for current batch and fulfilment information.
Is olive oil a medicine?
No. Olive oil is a food, not a medicine. It has a long traditional history — including being honoured in the Prophetic Sunnah — and a substantial body of modern research, particularly around polyphenols, cardiovascular health, and the Mediterranean diet pattern. It can be a worthwhile part of a healthy routine, but it does not cure diseases and is not a substitute for medical care. Be cautious of any olive oil marketed with specific disease-cure claims.
Final Thoughts
Seven grams in an observational cohort, 20 g in a conditional EU claim, and four tablespoons within a Mediterranean diet trial belong in different columns. None is a universal instruction for tomorrow's spoon. The useful question is where the oil goes in a meal and what it replaces.
