Ginger ale has long been considered the go-to beverage for a queasy stomach, often reached for when battling motion sickness or general digestive upset. The widespread belief is that the ginger flavor alone is enough to soothe internal turmoil. To understand the effectiveness of this common remedy, it is necessary to separate the medicinal properties of the natural root from the ingredients found in the mass-produced soft drink.
The Science of Ginger and Nausea Relief
The anti-nausea power of the ginger plant, Zingiber officinale, comes from its active compounds known as gingerols and shogaols. These compounds are concentrated in the fresh or dried root and are responsible for the distinct flavor and therapeutic benefits. Gingerols and shogaols exert their effect by interacting with specific receptors in the body that control the vomiting reflex.
These compounds act as antagonists, blocking the action of serotonin on the 5-HT3 receptors found in the gut and the central nervous system. When the body senses distress, it releases serotonin, which triggers the nausea sensation by activating these receptors. By blocking this activation, ginger directly interrupts the signal traveling from the digestive tract to the brain’s vomiting center.
Beyond the nervous system, ginger also works directly on the digestive process. Studies show that these compounds can modulate gastrointestinal motility and stimulate gastric contractions, accelerating the rate at which the stomach empties its contents. This dual action—calming neurological signals and moving stomach contents along—is the proven mechanism behind ginger’s ability to settle the stomach.
Decoding Commercial Ginger Ale
The issue with relying on typical store-bought ginger ale is its fundamental composition, which often contains minimal to no therapeutic ginger extract. Most mainstream brands primarily consist of carbonated water, high-fructose corn syrup or sugar, and “natural flavors.” These flavors provide the ginger taste without the medicinal compounds, and the small amount of flavoring included is not the concentration required to elicit biological effects observed in clinical studies.
The high sugar content in these sodas can work against the goal of settling the stomach. A typical can of ginger ale contains around 30 to 40 grams of sugar, which can trigger an osmotic effect in the digestive system. This process pulls water into the intestines to dilute the sugar, potentially leading to bloating, cramping, and diarrhea, which can worsen existing digestive upset.
Furthermore, the rapid intake of a high-sugar beverage can cause a spike in blood sugar, followed by a drop, which can induce feelings of nausea and lightheadedness. While the carbonation might provide a brief, temporary sense of relief by encouraging a burp that releases trapped gas, the gas itself can also contribute to bloating and discomfort in a sensitive stomach.
The Verdict: Real Ginger Versus the Soda
Most commercial ginger ales do not contain a sufficient quantity of gingerols and shogaols to be considered a therapeutic anti-nausea remedy. Any relief experienced from drinking a standard ginger ale is most likely a combination of the placebo effect and the temporary calming sensation of the cold, carbonated liquid. For true relief based on the physiological mechanisms of the root, the ginger must be present in a concentrated, active form.
Effective delivery methods include steeping fresh, grated ginger root in hot water to make tea, or consuming high-concentration ginger chews or capsules. Some artisanal or craft ginger ale brands do contain measurable amounts of real ginger extract, often between 0.5% and 1.2%, which is closer to a beneficial dose. Consumers should check the ingredient label for “ginger root extract” rather than relying on generic “natural flavors” to ensure they are getting the active compounds.
Practical Alternatives for Settling the Stomach
When dealing with a sensitive stomach, focusing on bland, easily digestible foods and proper hydration is a more reliable approach than relying on sugary sodas. The BRAT diet, which stands for bananas, rice, applesauce, and toast, is often recommended because these foods are low in fat and fiber. These starchy foods are gentle on the digestive tract, helping to bind loose stools and avoid irritating the stomach lining.
Hydration is particularly important, and clear liquids like oral rehydration solutions or plain broth help replace lost water and electrolytes without overwhelming the digestive system. While ginger ale is acceptable as a clear liquid, consuming electrolyte solutions is a superior choice because they replenish essential minerals lost during illness.
Non-dietary methods, such as controlled deep breathing exercises, can help manage the sensation of nausea by calming the nervous system. When eating, it is helpful to consume small, frequent meals. Avoid foods that are greasy, spicy, or have strong odors, as these factors can often trigger or worsen feelings of queasiness.
