The Tannin Connection: How Olives Address Motion Sickness
For those who experience motion sickness, a common and unpleasant side effect is the overproduction of saliva, which can intensify feelings of nausea. This is where the tannins in olives come into play. Tannins are naturally occurring compounds known for their astringent properties, meaning they have a drying effect. When consumed, the tannins in olives can help dry out the mouth, counteracting the excess salivation and potentially reducing the sensation of nausea before it escalates. It's a simple, biological mechanism that explains why this remedy has been passed down for generations as a quick fix for queasiness on a boat, plane, or in a car.
More Than Just Tannins: The Role of Salty Flavor
The salty flavor of brined olives can also offer a psychological and physiological benefit. When feeling nauseous, bland, salty, and crunchy foods like crackers are often recommended to help settle the stomach. The intense, briny flavor of olives can provide a sensory distraction from the queasy feeling and may help reset the palate. This aligns with why other salty foods are suggested to help manage nausea, particularly after vomiting has led to a loss of electrolytes.
Aiding Morning Sickness and Electrolyte Imbalance
Morning sickness during pregnancy is another common cause of nausea, often accompanied by vomiting that can deplete the body's store of sodium and other electrolytes. In these cases, olives can serve a dual purpose. Their high sodium content can help replenish electrolytes lost through fluid expulsion, assisting the body in rebalancing itself. While helpful, this should be done in moderation, as excessive sodium intake is not recommended during pregnancy. However, a few olives as a snack can be a good way to address both the queasiness and electrolyte imbalance at the same time.
Digestive Health Benefits for Nausea Prevention
Beyond immediate relief, the broader digestive health benefits of olives can also play a role in preventing nausea. Some olives are produced through natural lactic acid fermentation, a process that creates probiotics beneficial for gut health. A balanced and healthy gut microbiome is crucial for proper digestion and can indirectly help reduce the frequency of digestive upset. Olives also contain dietary fiber, which aids in digestion and helps regulate the digestive system, further promoting overall gut health.
Potential Probiotic Power
- Support for the gut microbiome: Certain varieties of olives, particularly those preserved in salt brine, may contain probiotic bacteria that support healthy digestion.
- Improved regularity: The fiber in olives helps regulate bowel movements, preventing constipation which can sometimes be a contributing factor to nausea.
- Reduced inflammation: Compounds in olives have anti-inflammatory properties that can help soothe an inflamed gut, which is a potential source of digestive discomfort.
Is It the Olive or the Salinity?
To understand if the olive itself or its preparation is the key to alleviating nausea, it's useful to compare it with other remedies.
| Feature | Olives | Saltines/Crackers | Ginger | Lemons | Sports Drinks | 
|---|---|---|---|---|---|
| Primary Mechanism | Tannins, salt, distraction | Absorb stomach fluid, blandness | Anti-inflammatory, gingerols | Inhaled scent, acid, distraction | Electrolyte replenishment | 
| Active Compounds | Tannins, sodium | Bicarbonate of soda | Gingerol, shogaol | Citric acid | Sodium, potassium, sugar | 
| Effect on Salivation | Reduces it | Absorbs excess fluid | Indirectly calms stomach | Dries the mouth | Replenishes fluids | 
| Target Nausea Type | Motion sickness, morning sickness | Empty stomach, general | Pregnancy, general | Motion sickness | Vomiting-related | 
| Sodium Content | High (especially brined) | Moderate | Low | Low | Moderate to high | 
Considerations and Precautions
While olives can be a helpful and easy remedy for some, they are not a universal cure and should be consumed in moderation. As mentioned, the high sodium content of brined olives is a significant factor. For individuals with high blood pressure or other salt-sensitive conditions, an excessive intake could be problematic. It is also important to choose the right kind of olive. Some canned or highly processed varieties may contain less of the beneficial compounds and more artificial additives. Naturally brined, fermented olives tend to be the most beneficial for digestive health due to their potential probiotic content.
What to Know Before You Try
When using olives to combat nausea, timing and quantity are important. Many proponents of the remedy suggest eating just a couple of olives at the very onset of the nauseous feeling. Eating too many could potentially backfire due to the high fat and sodium content, which could further upset a sensitive stomach.

Conclusion
For certain types of nausea, particularly motion sickness and morning sickness, olives can offer a surprising and simple form of relief. Their tannins can help combat excessive salivation, and their salt content can aid in restoring electrolyte balance lost from vomiting. While not a guaranteed fix for all causes of nausea, and certainly not a replacement for medical advice for severe or chronic symptoms, incorporating a few olives into your routine at the first sign of discomfort is a low-risk folk remedy worth considering. Like any dietary change for a health issue, consulting a healthcare provider is always recommended, especially for pregnant individuals or those with pre-existing health concerns.
