What is Diabetes, and How Does It Affect Blood Sugar?

Diabetes is a metabolic disease where the body struggles to regulate blood sugar, or glucose, effectively. In type 1 diabetes, the body cannot produce insulin, a hormone needed to help cells absorb glucose. People with type 2 diabetes, the more common form, may produce insulin, but their bodies have difficulty using it properly, often leading to higher glucose concentrations in the bloodstream.


Managing blood glucose levels is essential for people with diabetes because uncontrolled blood sugar can cause severe health complications. Keeping glucose levels within a healthy range helps protect against issues like cardiovascular disease, impaired fasting glucose, and other cardiometabolic risk factors associated with diabetes. Monitoring and balancing blood sugar is a daily focus for diabetics to prevent complications and improve overall well-being.

Is Olive Oil Good for Diabetics?

Yes, olive oil, especially extra virgin olive oil or EVOO, can be beneficial for diabetics. Its healthy fats, particularly monounsaturated fats, and bioactive compounds support blood sugar control and promote cardiovascular health, which is vital for managing diabetes.

How Does Olive Oil Affect Blood Sugar Levels?

Olive oil has a low glycemic index and contains healthy fats that help slow down the absorption of glucose, preventing sudden spikes in blood sugar. The monounsaturated and polyunsaturated fatty acids in olive oil contribute to stable blood glucose levels, which is essential for people with diabetes. Including olive oil in meals can help manage blood sugar and support metabolic control, benefiting those with impaired glucose regulation.

Olive Oil and Insulin Sensitivity

Olive oil, particularly its high oleic acid content, is known to improve insulin sensitivity, reducing insulin resistance risk. The dietary polyphenols in extra virgin olive oil promote better glucose metabolism, supporting insulin target tissues to work more effectively. By enhancing insulin sensitivity, olive oil helps people with diabetes manage their blood glucose levels and maintain a healthier balance in glucose concentration over time.

The Health Benefits of Olive Oil for Diabetics

Olive oil offers unique health benefits for diabetics, making it an ideal addition to a balanced diet. Its powerful antioxidants, anti-inflammatory properties, and heart health benefits support diabetes management and overall wellness.

Rich in Antioxidants

Olive oil, especially extra virgin olive oil, is packed with antioxidants like polyphenols, which are essential for combating oxidative stress, a condition that is particularly common in people with diabetes. Oxidative stress occurs when free radicals damage cells, which can contribute to complications associated with impaired glucose regulation.


The phenolic compounds in olive oil provide a natural defense against these free radicals, helping to protect cells and improve metabolic control. By supporting glucose metabolism and cellular health, olive oil’s antioxidants promote better blood sugar control and overall diabetes management.

Anti-Inflammatory Properties

Chronic inflammation is a common issue for individuals with diabetes and can worsen insulin resistance. Olive oil contains powerful anti-inflammatory compounds that help lower inflammation throughout the body, which benefits insulin-target tissues.


Olive oil intake supports insulin sensitivity, aiding in better blood glucose control and reducing the risk of complications linked to diabetes. Lowering inflammation with the help of dietary fats like olive oil also contributes to overall metabolic health, helping to keep blood glucose levels stable.

Heart Health and Diabetes

Maintaining heart health is crucial for those managing diabetes, as they face a higher risk of cardiovascular disease and other cardiometabolic risk factors. Olive oil supports cardiovascular health by lowering LDL (bad) cholesterol while increasing HDL (good) cholesterol.


This balance is essential for reducing cardiovascular risk factors and blood lipids. By improving blood pressure, blood lipids, and overall endothelial function, olive oil contributes to better heart health, which is vital for diabetics aiming to prevent further complications.

Olive Oil Intake: How Much Olive Oil Should Diabetics Consume?

For people with diabetes, a recommended intake of one to two tablespoons of olive oil daily can provide substantial health benefits. This portion delivers healthy fats, such as monounsaturated and polyunsaturated fats, and an optimal amount of bioactive compounds without adding too many calories. Extra virgin olive oil is ideal, as it has a high concentration of beneficial dietary polyphenols and fatty acids that support insulin sensitivity and metabolic control.


Using moderation is essential, as olive oil, like other dietary fats, is calorie-dense. Balancing olive oil consumption with other healthy fats, such as fish oil, nuts, or vegetable fats, can provide a well-rounded source of dietary fats for diabetics. This variety helps manage body weight and offers a wide array of nutrients essential for stable blood glucose and metabolic health.

Practical Tips to Use Olive Oil for Managing Diabetes

Incorporating olive oil into your diet can support diabetes management and help control blood sugar. Here are some simple, practical ways to use olive oil in a diabetic-friendly way.

Cooking with Olive Oil

Cooking with olive oil is an excellent way to enjoy its health benefits, but there are some tips to get the most from it:

  • Use it in salads and dressings: Drizzle extra virgin olive oil over salads to enjoy its antioxidants and healthy fats in their purest form.

  • Cook at moderate temperatures: EVOO has a smoke point of about 375°F (190°C), making it suitable for most cooking methods except high-temperature frying. Olive oil retains its benefits best at low to medium heat.

    Add it to finished dishes: Stirring a spoonful into soups, vegetables, or pasta after cooking preserves more of its bioactive compounds.


Using Olive Oil in the Mediterranean Diet


The Mediterranean diet, rich in olive oil, is well-known for supporting heart health and managing diabetes. Here’s how to adopt this style:


  • Use olive oil as a primary fat: Substitute other fats like butter with olive oil for cooking and flavor.

  • Pair with vegetables and whole grains: Enjoy olive oil with fiber-rich foods that support glucose control.

  • Include lean protein sources: Fish, legumes, and poultry combined with olive oil make a well-rounded, blood sugar-friendly meal.

Research on Olive Oil and Diabetes

Research has shown promising results in linking olive oil consumption with better blood sugar management, adding evidence to its value for diabetics.

Studies on Blood Sugar and Olive Oil

Several studies highlight how olive oil positively affects blood sugar control. For instance, a meta-analysis and systematic review conducted in the study titled  Olive oil in the prevention and management of type 2 diabetes mellitus: a systematic review and meta-analysis of cohort studies and intervention trials has shown that olive oil intake can help stabilize plasma glucose values and improve insulin sensitivity.


This study reveals that the unique fatty acid composition and polyphenols in olive oil enhance glucose metabolism, making it a valuable dietary fat for diabetics.

Future Research and What We Still Need to Know

Although research supports olive oil’s benefits for blood sugar and insulin resistance, there are still gaps to fill. Researchers continue to explore olive oil’s exact impact on insulin target tissues and other cardiometabolic risk factors in diabetic patients, such as in the study called Olive oil has a beneficial effect on impaired glucose regulation and other cardiometabolic risk factors.
