Diabetes Treatment Using Olive Oil

Could something as simple as a tablespoon of the right olive oil, taken morning and evening, make a meaningful difference to blood sugar regulation and diabetes management? The science — and over 50 years of clinical experience at Planet Wellness — suggests it absolutely can. But only if you choose the right type, and understand why it works.

Why Quality Fats Are Essential for Diabetics

One of the most damaging myths in modern nutrition is that fat is the enemy. For people with diabetes, this misconception can actively worsen their condition. The truth is that your body needs high-quality fats — not to be avoided, but to function correctly.

Here is why this matters particularly for diabetes: the pancreas, which produces insulin and digestive enzymes to break down sugars, works in close partnership with the liver and gallbladder. The liver and gallbladder process fats and oils, producing bile to emulsify them. These two systems — one for sugar regulation on the left side of the body, one for fat processing on the right — are deeply interdependent.

When you deprive your body of quality fats, or worse, supply it with poor-quality processed oils, you impair the function of both the pancreas and the liver simultaneously. This creates a double burden for the diabetic body. Conversely, when you supply the right fats in the right amounts, you actively support both organs.

In this video, we share exactly how to use olive oil as part of a natural approach to diabetes management, drawing on our decades of experience with diabetic patients.

What the Science Says About Olive Oil and Blood Sugar

Extra virgin olive oil is one of the most thoroughly researched foods in the world, and its benefits for people with diabetes are well established:

• Reduces post-meal blood glucose: Studies consistently show that including olive oil in a meal significantly lowers the blood glucose response. The healthy monounsaturated fats slow glucose absorption and improve insulin sensitivity.
• Rich in polyphenols and antioxidants: High-quality extra virgin olive oil contains powerful antioxidant compounds including oleocanthal and oleuropein, which combat the oxidative stress caused by chronically elevated blood sugar — one of the primary mechanisms through which diabetes causes long-term damage.
• Strongly anti-inflammatory: Chronic inflammation is both a cause and a consequence of Type 2 diabetes. Olive oil’s anti-inflammatory properties directly address this underlying driver of the condition.
• Supports healthy cholesterol: Diabetic patients are at significantly elevated risk of cardiovascular disease. Olive oil raises HDL (“good”) cholesterol and reduces LDL oxidation, providing meaningful cardiovascular protection.
• Supports liver and gallbladder function: Quality fats stimulate healthy bile production and flow, supporting the liver’s detoxification functions and the gallbladder’s role in fat digestion — both frequently compromised in diabetic patients.

How to Choose the Right Olive Oil — This Is Critical

Not all olive oil is equal, and for therapeutic purposes the distinction matters enormously. Here is exactly what to look for:

• Extra virgin, cold-extracted: Only cold extraction preserves the full spectrum of polyphenols and antioxidants. Heat processing destroys these beneficial compounds.
• Organic: Pesticide residues in conventional olive oil add to the toxic load on the liver — counterproductive when you are trying to support liver function.
• Stored in dark glass (amber bottle): Light degrades olive oil rapidly. Clear plastic bottles are completely unsuitable — they allow oxidation and light damage that renders the oil pro-inflammatory rather than anti-inflammatory.
• Fresh and ideally single-origin: Olive oil from a single estate or region (Greece, Spain, Italy) is less likely to be blended or adulterated. Check the harvest date — freshness matters.
• The throat-bite test: Good quality, polyphenol-rich extra virgin olive oil produces a distinct peppery bite at the back of the throat when tasted neat. This sensation is the oleocanthal at work. If your olive oil tastes bland and neutral, it lacks the therapeutic compounds you need.

We specifically recommend organic, cold-extracted extra virgin olive oil produced and grown in Greece. Avoid cheap vegetable oils in clear plastic bottles entirely — these industrially processed oils are actively damaging to both the pancreas and the liver.

How to Use Olive Oil for Diabetes Management

• Morning and evening dose: Take one tablespoon of high-quality extra virgin olive oil in the morning and one tablespoon in the evening. This consistent daily intake helps regulate blood sugar and supports liver function throughout the day.
• Drizzle on salads and cooked foods: Use it liberally over vegetables, legumes, and salads — this is how the Mediterranean populations who inspired olive oil research consume it naturally.
• Low-heat cooking: Olive oil can be used for gentle sautéing. Avoid high-heat frying — high temperatures degrade the fats and destroy the beneficial compounds. For high-heat cooking, coconut oil or butter is preferable.
• As a bread dip: A far healthier alternative to butter, particularly with a squeeze of lemon and a pinch of quality sea salt.

Olive Oil for Type 1 and Type 2 Diabetes

Whether you have Type 1 or Type 2 diabetes, quality olive oil has a role to play. In Type 2, where insulin resistance and lifestyle factors are central, olive oil’s impact on glucose response and inflammation can be particularly significant. In Type 1, where the pancreas produces little or no insulin, supporting the liver and reducing oxidative burden remains highly valuable for overall health and long-term complication prevention.

As with all nutritional interventions, olive oil works best as part of a comprehensive, personalised approach — not in isolation. At Planet Wellness, with over 50 years of experience working with diabetic patients, we combine nutritional guidance, Iridology assessment, and natural supplementation to create a plan that addresses the whole person, not just the blood sugar number.
