What happens when you take a shot of olive oil before you drink? Separating Myth from Fact

3 min read

While the theory of 'lining your stomach' with olive oil has been around for decades, science confirms that only about 20% of alcohol is absorbed through the stomach lining, with the rest entering the small intestine. Taking a shot of olive oil before you drink might delay some absorption, but it won't prevent a hangover entirely.

Quick Summary

Drinking olive oil before alcohol can slightly delay absorption by slowing gastric emptying, but it does not prevent hangovers, which are caused by alcohol metabolism, dehydration, and inflammation.

Key Points

  • Delayed Absorption, Not Prevention: Taking a shot of olive oil before drinking can slightly slow alcohol absorption by delaying gastric emptying, but it will not prevent intoxication or a hangover.

  • Hangovers Are Complex: Hangovers are primarily caused by dehydration, inflammation, and toxic byproducts of alcohol metabolism, not just fast absorption.

  • A Full Meal is Better: A balanced meal with protein, fats, and carbohydrates is significantly more effective at slowing alcohol absorption than a shot of olive oil alone.

  • Placebo Effect is Real: Anecdotal evidence for the olive oil trick often comes from the placebo effect, where believing a remedy works can lead to perceived benefits.

  • Hydration is Key: The most effective strategies for preventing a hangover involve drinking water alongside alcohol to combat dehydration.

  • Moderation is the Only Cure: The best way to avoid a hangover is to drink in moderation and not rely on unproven hacks to mitigate the effects of excessive consumption.

The Mediterranean Myth: Understanding the 'Coating' Theory

For years, a folk remedy suggested that a shot of olive oil before drinking could help prevent a hangover. The idea is that the oil would coat the stomach lining and slow alcohol absorption. However, this overlooks the complexities of digestion and alcohol metabolism.

The Reality of Alcohol Absorption

Alcohol absorption is a multi-step process, with most occurring in the small intestine, not the stomach. While some absorption happens in the stomach, the 'coating' effect of olive oil is minimal and temporary due to the stomach's natural digestive processes.

  • Gastric Emptying Delay: Consuming fatty food like olive oil before drinking can delay gastric emptying, meaning alcohol reaches the small intestine slower, resulting in a more gradual rise in blood alcohol concentration (BAC).
  • Not an 'Absorption Stopper': This delay does not prevent absorption; all alcohol will eventually enter the bloodstream. Relying on olive oil might lead to drinking more and a worse hangover later.

The True Causes of Hangovers and What Actually Helps

Hangovers result from dehydration, inflammation, and toxic byproducts like acetaldehyde, not just rapid alcohol absorption. Effective prevention addresses these root causes.

Comparison: Olive Oil vs. A Balanced Meal

Feature Shot of Olive Oil Balanced Meal (Protein, Fats, Carbs) Outcome
Slowing Absorption Minor and temporary delay in gastric emptying due to fat content. Significant delay due to fat, protein, and fiber. A balanced meal is more effective at slowing absorption.
Nutrient Support Provides healthy fats and antioxidants. Replenishes vitamins, minerals, and electrolytes depleted by alcohol. A balanced meal offers far more nutritional support.
Stomach Irritation May soothe the stomach lining slightly. Can help line the stomach with complex nutrients, reducing irritation. Both offer some benefit, but a meal is more substantial.
Dehydration Counteraction Does not directly address dehydration. Does not directly address dehydration. Must be paired with water. Neither is a solution for dehydration alone.
Overall Effectiveness Limited and based on anecdotal evidence or placebo effect. Scientifically proven to mitigate some alcohol effects. A balanced meal is the superior choice for preparation.

Evidence-Based Alternatives for Mitigation

Focus on these scientifically supported methods instead of an olive oil shot:

  1. Eat a Substantial Meal: A meal with protein, fats, and carbohydrates is more effective at slowing absorption than oil.
  2. Stay Hydrated: Alcohol is a diuretic, causing dehydration, a major hangover cause. Drink water between alcoholic drinks.
  3. Drink in Moderation: Limiting intake is the most reliable way to prevent a hangover, as the body can only metabolize a certain amount of alcohol per hour.
  4. Supplement Electrolytes: Electrolyte-rich drinks or foods can replenish those lost due to alcohol.

Conclusion: Responsible Drinking, Not Quick Fixes

The idea that olive oil prevents hangovers is largely a myth. While it may slightly delay alcohol absorption, a balanced meal is much more effective. Hangovers are caused by dehydration, inflammation, and toxins, which olive oil doesn't address. The best prevention involves eating before drinking, staying hydrated, and drinking in moderation. Olive oil offers health benefits as part of a healthy diet, not as a pre-drinking remedy. Read more on the Mediterranean diet for overall health benefits.

How Olive Oil Contributes to Well-being (Separately)

Extra virgin olive oil is beneficial in a healthy diet due to antioxidants and healthy fats that support heart health and reduce inflammation. Incorporating it into meals offers genuine health benefits, separate from its ineffective use as a pre-party remedy. Focusing on long-term wellness and responsible choices is key.

Frequently Asked Questions

No, the theory that olive oil can 'coat' the stomach to block alcohol absorption is a myth. The stomach's acidic environment and digestive processes quickly disperse the oil. While the fat can slightly slow gastric emptying, it does not form a protective, impenetrable layer.

No, a shot of olive oil does not prevent a hangover. Hangovers are caused by multiple factors, including dehydration, inflammation, and the toxic effects of acetaldehyde. Delaying absorption does not prevent these biological processes.

Yes, eating a full, balanced meal with protein, fats, and carbs is more effective than just drinking olive oil. This is because a full meal significantly slows the rate of gastric emptying, thereby delaying alcohol absorption more effectively and providing more nutrients.

The most reliable way to prevent a hangover is to drink in moderation, stay well-hydrated by drinking water throughout the night, and eat a substantial meal beforehand. Avoiding excessive consumption is key.

Yes, it could be dangerous. Relying on this trick may give you a false sense of security, leading you to drink more than you normally would. When the delayed alcohol eventually hits your bloodstream, the effects could be much more intense and unexpected.

While extra virgin olive oil has general health benefits due to its antioxidants and healthy fats, these benefits are not potent enough to counteract the massive oxidative stress caused by excessive alcohol consumption. There is no specific, scientifically-proven benefit for this use case.

If you still choose to try it, understand its limitations. A small dose might slightly delay the initial feeling of intoxication, but it is not a fail-safe. You must still adhere to proper hydration and moderation to avoid a severe hangover.
