What Research Shows
Effects on Blood Sugar
Recent studies highlight olive oil's role in managing blood sugar. A meta-analysis involving 15,784 cases of type 2 diabetes found that people who consumed the most olive oil had better control over their blood sugar levels. Extra virgin olive oil (EVOO), in particular, was shown to reduce post-meal blood sugar levels thanks to its natural compounds, making it a helpful choice for those keeping an eye on their glucose levels.
Better Insulin Response
Research also shows that EVOO helps improve how the body responds to insulin. According to findings published in Diabetes Care Journal, the monounsaturated fats in olive oil enhance the body's sensitivity to insulin. This means individuals experience more stable blood sugar levels throughout the day.
"Although both inclusion and exclusion of extra virgin olive oil within a whole food, plant-based vegan diet support cardiometabolic disease risk reduction compared with a standard omnivorous pattern, decreased intake of extra virgin olive oil may yield increased lipid lowering than relatively greater consumption."
Lower Type 2 Diabetes Risk
One of the most eye-opening discoveries is the link between olive oil consumption and reduced type 2 diabetes risk. Long-term research shows that regularly eating EVOO can lower the risk of developing type 2 diabetes by 16%, compared to those who consume little to none. This is largely due to the oleuropein and phenolic compounds in olive oil, which have anti-diabetic properties.
These benefits are most effective when EVOO is part of a balanced diet, making it an excellent choice for those aiming to prevent diabetes or keep their blood sugar levels in check through diet changes.
How Olive Oil Helps Control Blood Sugar
Healthy Fats and Natural Compounds
Olive oil's ability to help manage blood sugar lies in its unique blend of nutrients. A key player here is oleic acid, a type of monounsaturated fat that helps maintain stable blood glucose levels. Additionally, it contains natural compounds like oleuropein, which act as antioxidants, boosting the body’s ability to manage sugar more efficiently.
"The combination of varying types of saturated, mono-unsaturated, and poly-unsaturated fatty acids in olives provides a unique nutrient profile", says Monique Richard, MS, RDN, LDN, emphasizing how these elements work together to support blood sugar stability.
Fighting Inflammation
Chronic inflammation can lead to insulin resistance, but olive oil’s natural anti-inflammatory properties help address this issue. Extra virgin olive oil (EVOO) is packed with antioxidants that reduce inflammatory markers in the body, helping insulin work as it should. This benefit is particularly strong in high-quality EVOOs, where careful processing helps retain their nutrient-rich compounds.
Supporting Heart Health
Heart health and blood sugar management are closely linked, and olive oil benefits both. By helping to balance cholesterol levels, it promotes better cardiovascular health, which in turn supports how the body regulates glucose. Studies show people who regularly consume olive oil as part of a Mediterranean-style diet are 16% less likely to develop type 2 diabetes, highlighting the connection between heart wellness and blood sugar control.
Choosing the right olive oil is crucial for reaping these benefits. Ultra Premium Extra Virgin Olive Oil, such as those from Big Horn Olive Oil, preserves more beneficial nutrients because it is cold-pressed within two hours of harvest. This meticulous process locks in the bioactive compounds key to supporting blood sugar health.

Using Olive Oil for Blood Sugar Control
How Much Olive Oil Should You Consume?
Studies show that a consistent intake of extra virgin olive oil (EVOO) can help manage blood sugar levels effectively. Research highlights that consuming 2-4 tablespoons (30-60ml) of EVOO per day led to improvements in both hemoglobin A1c and fasting plasma glucose levels. But here’s the catch - olive oil is high in calories, so it’s best to factor it into your total daily caloric intake.
"Even healthy fats like olive oil should be consumed in moderation, particularly for those monitoring their caloric intake for blood sugar management." - Meta-analysis findings from diabetes management studies
Making the Most of Olive Oil in Cooking
For the best blood sugar benefits, focus on cooking methods that preserve EVOO's healthful compounds. Phenolic compounds in EVOO play an important role in slowing carbohydrate digestion and stabilizing blood sugar. Using it for low-temperature cooking or in uncooked dishes helps retain these compounds.
Here are a few ways you can effectively add EVOO to your meals:
| Method | Temperature | Best Uses | Blood Sugar Impact |
|---|---|---|---|
| Raw/Cold | None | Salad dressings, dips | Maintains all compounds for the maximum effect |
| Low-heat cooking | Below 320°F | Sautéing vegetables | Preserves most compounds for a high benefit |
| Medium-heat cooking | Up to 374°F | Light stir-frying | Retains some compounds for a moderate benefit |

Next Steps in Research
Current Study Limits
Although research suggests a connection between olive oil and improved blood sugar control, there are some clear limitations. Most studies so far have focused on short-term impacts, typically lasting only 3–6 months. To fully understand how olive oil affects blood sugar over the long haul or its potential in preventing type 2 diabetes, longer-term studies are essential.
"Although both inclusion and exclusion of extra virgin olive oil within a whole food, plant-based vegan diet support cardiometabolic disease risk reduction compared with a standard omnivorous pattern, decreased intake of extra virgin olive oil may yield increased lipid lowering than relatively greater consumption." - Monica Aggarwal, M.D.
While current statistics - like a 16% lower risk of type 2 diabetes in frequent olive oil consumers - are promising, they need validation through larger, more diverse studies. Greater variation in participants could help confirm these findings on a broader scale.
Future Research Needs
Several key areas require deeper investigation to better understand olive oil's potential benefits:
| Research Priority | Current Knowledge Gap | Impact on Understanding |
|---|---|---|
| Compound Mechanisms | How oleuropein and elenolic acid influence insulin sensitivity | More precise dosage recommendations |
| Population Differences | Effects across age groups and ethnic backgrounds | Tailored dietary advice for diverse groups |
| Food Interactions | How EVOO works with other foods or medications | Enhanced meal-planning strategies |
Scientists need to dive deeper into the mechanisms of olive oil’s active compounds, such as oleuropein, especially in combination with both food and diabetes medications. Another goal should be identifying whether certain types of olive oil or production methods offer better effects on blood sugar control.
Additionally, current intake recommendations are based on limited evidence. Pinpointing optimal daily amounts for different groups could help doctors and nutritionists offer more specific advice on using olive oil as part of a broader blood sugar management plan.
