Understanding the Science Behind Why do I feel better after drinking olive oil?

4 min read

An estimated 25% of adults over 60 suffer from constipation, and a 2014 study found that just one teaspoon of olive oil daily was as effective as mineral oil for relief. So, why do I feel better after drinking olive oil? The reasons are multifaceted, involving its healthy fats, anti-inflammatory compounds, and digestive benefits.

Quick Summary

The feeling of improved well-being from consuming olive oil stems from its anti-inflammatory effects, digestive aid, rich antioxidant content, and heart-healthy monounsaturated fats.

Key Points

  • Reduces Inflammation: Olive oil contains oleocanthal, a compound with anti-inflammatory properties similar to ibuprofen, which combats chronic inflammation.

  • Aids Digestion: It acts as a natural lubricant and stool softener, promoting smoother bowel movements and alleviating constipation.

  • Supports Gut Microbiome: The polyphenols in extra virgin olive oil act as prebiotics, nourishing beneficial gut bacteria for improved digestive health.

  • Boosts Nutrient Absorption: The healthy fats in olive oil enhance the body's ability to absorb essential fat-soluble vitamins, including A, D, E, and K.

  • Promotes Satiety: Rich in monounsaturated fats, olive oil helps you feel full longer, which can aid in appetite regulation and weight management.

  • Protects Heart Health: Its monounsaturated fats help lower LDL cholesterol, reducing the risk of heart disease.

The Anti-Inflammatory and Antioxidant Power of Olive Oil

One of the most significant reasons people report feeling better after consuming olive oil is its potent anti-inflammatory and antioxidant properties. Chronic, low-level inflammation is a known contributor to numerous health problems, including heart disease, arthritis, and metabolic syndrome. High-quality extra virgin olive oil (EVOO) contains compounds that help combat this. The primary anti-inflammatory agent is oleocanthal, which research shows works similarly to the nonsteroidal anti-inflammatory drug ibuprofen. Additionally, olive oil is rich in powerful antioxidants, such as polyphenols, which fight oxidative stress by neutralizing harmful free radicals. This protective effect not only reduces inflammation but also benefits cardiovascular and neurological health.

The Digestive and Gut Health Connection

Olive oil has been used for centuries as a natural remedy for digestive issues, and modern science supports this tradition. Its effect on the digestive system is a key factor in feeling better. It acts as a lubricant, smoothing the intestinal tract and softening stools, which can be very effective in relieving constipation. Unlike harsh laxatives, it provides a gentle, non-stimulant effect. Moreover, olive oil stimulates bile production, which helps the body efficiently break down and absorb fats and other nutrients. A healthier digestive process reduces issues like bloating and general discomfort. EVOO's high polyphenol content also functions as a prebiotic, feeding beneficial gut bacteria (probiotics), which leads to a more balanced and diverse gut microbiome. A healthy gut is linked to better overall wellness, mood, and immunity.

The Role of Healthy Fats in Satiety and Energy

Olive oil is predominantly made up of monounsaturated fatty acids (MUFAs), particularly oleic acid. These healthy fats play a crucial role in overall well-being. Unlike saturated fats, MUFAs can help improve cholesterol levels by lowering LDL ('bad') cholesterol while potentially increasing HDL ('good') cholesterol. This contributes to better heart health, a foundational component of feeling well. Beyond heart health, the healthy fats in olive oil promote a sense of fullness and satiety. This can help regulate appetite and prevent overeating, which often leads to discomfort and sluggishness. By providing sustained energy and improving metabolic function, olive oil can contribute to a feeling of vitality and lightness throughout the day.

Drinking vs. Incorporating: A Balanced Approach

While some cultures practice drinking olive oil, particularly on an empty stomach, to maximize benefits, there is limited evidence to suggest this is more effective than including it in meals. In fact, consuming olive oil with food, like tomatoes, can significantly increase the absorption of disease-fighting antioxidants. Drinking too much olive oil can also lead to digestive issues like diarrhea due to its laxative properties. The most sustainable and enjoyable way to reap the benefits is to integrate it into a balanced diet. The Mediterranean diet, rich in vegetables, fruits, whole grains, and olive oil, is a prime example of a successful and healthy dietary pattern.

Ways to Incorporate Olive Oil into Your Diet

  • Dressings and Drizzles: Use a high-quality EVOO as a finishing oil for salads, roasted vegetables, grilled fish, or soups.
  • Cooking and Sautéing: Use olive oil for low-to-medium heat cooking. It is more stable than many other oils due to its monounsaturated fat content.
  • Baking: Substitute olive oil for butter or other oils in baking recipes for a healthier alternative.
  • Spreads: Drizzle olive oil on toast instead of butter for a flavorful and healthier start to your day.
  • Smoothies: A tablespoon of olive oil can add a boost of healthy fats to your morning smoothie.

Comparison: Olive Oil vs. Common Refined Oils

Feature Extra Virgin Olive Oil (EVOO) Refined Oils (Vegetable, Canola)
Extraction Process Cold-pressed; no heat or chemical solvents used. Extracted using heat and chemical solvents (e.g., hexane).
Antioxidant Content High in antioxidants like polyphenols and Vitamin E. Low, as most are removed during the refining process.
Anti-Inflammatory Properties Strong due to compounds like oleocanthal and oleic acid. Minimal, often pro-inflammatory if high in Omega-6s.
Fatty Acid Profile High in monounsaturated fats (oleic acid) and low in polyunsaturated fats. Higher in unstable polyunsaturated fats (Omega-6).
Flavor Distinct, robust, and fruity with peppery notes. Mild, neutral, and bland taste.
Smoke Point Suitable for moderate heat; stable up to 200°C/390°F. High smoke point, but less stable due to lower antioxidant content.

Conclusion: The Holistic Approach to Well-Being

Ultimately, the feeling of improved well-being from consuming olive oil is not a magical effect but a result of its scientifically-backed nutritional profile. The combination of anti-inflammatory compounds, healthy fats that aid digestion and satiety, and potent antioxidants creates a holistic positive effect on the body. Whether drunk directly in moderation or, more commonly, incorporated into a balanced dietary pattern like the Mediterranean diet, olive oil offers tangible benefits. The key is to choose high-quality extra virgin olive oil and use it as a part of a wider healthy eating strategy, rather than viewing it as a cure-all. Moderation is vital, as excessive intake can lead to unwanted weight gain and digestive discomfort. By understanding the 'why' behind feeling better, you can make smarter dietary choices and unlock the full potential of this liquid gold for your health.
