The Truth About Drinking Oil for Health
While some wellness trends suggest drinking oil straight for a “health shot,” this practice is not supported by scientific evidence as providing greater benefits than standard culinary use. All oils are calorie-dense, and consuming them in large amounts can easily lead to excessive calorie intake and digestive issues, including diarrhea. The key to benefiting from healthy fats is moderation and incorporating them into a balanced diet where they can aid nutrient absorption from other foods.
The Healthiest Oils and How to Use Them
Extra Virgin Olive Oil (EVOO)
When considering what is the healthiest oil to drink? (or, more accurately, to consume), extra virgin olive oil consistently tops the list. A cornerstone of the heart-healthy Mediterranean diet, EVOO is the least processed type of olive oil and is rich in beneficial compounds. Its main benefits come from:
- Monounsaturated Fats (MUFAs): EVOO is high in oleic acid, a MUFA that can help lower LDL ("bad") cholesterol while maintaining or raising HDL ("good") cholesterol levels, protecting against heart disease.
- Antioxidants and Polyphenols: EVOO is packed with powerful antioxidants and anti-inflammatory compounds like oleocanthal and polyphenols. These compounds protect cells from oxidative damage caused by free radicals, a major driver of chronic diseases like cancer and heart disease.
- Flavor Profile: EVOO offers a distinct, peppery flavor that enhances dishes. It's best used for dressings, finishing dishes, and low-to-medium heat cooking to preserve its delicate compounds.
Avocado Oil
Avocado oil has a nutritional profile similar to olive oil and is another excellent choice. It is high in monounsaturated fats and boasts a very high smoke point, making it versatile for both low- and high-heat cooking methods like sautéing and searing. Its mild flavor makes it a good substitute for other oils in baking or general cooking.
Flaxseed Oil
Flaxseed oil is a potent source of alpha-linolenic acid (ALA), an omega-3 fatty acid that the body converts into other beneficial omega-3s. Omega-3s are crucial for reducing inflammation, supporting brain health, and lowering the risk of heart disease. Due to its very low smoke point, flaxseed oil should never be used for cooking. Instead, it is best added to cold dishes like smoothies, salad dressings, or drizzled over grains.
Oils to Consume in Moderation or Avoid
Not all oils are created equal, and some, particularly those high in saturated fats or heavily processed, should be consumed sparingly or avoided altogether for optimal health.
- Coconut Oil: Despite its popularity, coconut oil is around 90% saturated fat. While some studies suggest it may raise HDL cholesterol, it also raises LDL cholesterol more than unsaturated vegetable oils. The American Heart Association advises limiting saturated fat intake, placing coconut oil in the category of oils to use in moderation.
- Highly Refined Oils: Some refined vegetable and seed oils, like corn, soybean, and safflower, are high in omega-6 fatty acids. A balanced ratio of omega-6 to omega-3 is important for controlling inflammation. Over-reliance on omega-6-heavy oils can skew this ratio, potentially contributing to inflammation.
A Comparison of Popular Oils
| Feature | Extra Virgin Olive Oil (EVOO) | Avocado Oil | Coconut Oil |
|---|---|---|---|
| Fat Profile | High in MUFAs, some PUFAs | High in MUFAs, some PUFAs | High in Saturated Fats (MCTs) |
| Antioxidants | Very High (Polyphenols, Vitamin E) | High (Vitamin E) | Moderate (Polyphenols) |
| Smoke Point | Medium (approx. 350°F / 175°C) | Very High (approx. 520°F / 270°C) | Medium (approx. 350°F / 175°C) |
| Best Culinary Use | Dressings, finishing, low-medium heat cooking | High-heat cooking, baking | Moderate heat cooking, baking, moderation |
| Anti-Inflammatory Properties | Strong, due to oleocanthal and polyphenols | Moderate to Strong | Less evidence, potential for mixed effects on cholesterol |
| Heart Health | Strongly associated with reduced risk | Strong evidence | Conflicting evidence, limit due to saturated fat |
Healthy Ways to Incorporate Oils into Your Diet
Instead of drinking oil, integrate it into your food to enhance flavor and nutrient absorption. Here are some simple, healthy ways to use oil daily:
- Salad Dressings: Create your own vinaigrettes with EVOO, vinegar, and herbs for a fresh, nutrient-rich topping.
- Drizzle over Dishes: Add a finishing drizzle of high-quality EVOO or walnut oil over soups, pastas, or roasted vegetables to boost flavor and healthy fats.
- Sautéing and Roasting: Use avocado or refined olive oil for sautéing or roasting vegetables and lean proteins.
- Marinades and Sauces: Incorporate oil into marinades for meats or blend it into homemade sauces and dips like hummus.
- Smoothies: Add a teaspoon of flaxseed oil to smoothies for a boost of omega-3s.
- Baking: Substitute butter or other fats with oils like canola or avocado oil in baking recipes.
Conclusion
While the search for a single, definitive answer to what is the healthiest oil to drink? is understandable, the approach itself is misguided. The goal should be to incorporate the healthiest oils into a balanced diet in moderate amounts, rather than consuming them by the spoonful. Extra virgin olive oil stands out for its high content of monounsaturated fats and potent antioxidants, offering substantial benefits for heart health and inflammation. Paired with versatile options like avocado oil and omega-3 rich flaxseed oil, you can build a robust dietary strategy that maximizes wellness without the risks associated with excessive, direct consumption. The safest and most effective path to reaping the rewards of healthy oils is through mindful culinary use, not liquid shots.
