Canada Dry ginger ale is not good for you. A 12-ounce can contains 130 calories and 33 grams of sugar, nearly all of it from high fructose corn syrup. Despite its reputation as a stomach settler, it contains so little actual ginger that it offers no meaningful health benefit over any other sugary soda.
What’s Actually in a Can
The ingredient list is short: carbonated water, high fructose corn syrup, and then “less than 2%” of ginger extract, natural flavors, citric acid, sodium benzoate (a preservative), and caramel color. That “less than 2%” is doing a lot of heavy lifting. The ginger extract is so far down the list, and present in such small quantities, that it’s essentially a flavoring agent rather than a functional ingredient.
This became a legal issue. A class action lawsuit alleged that Dr Pepper Snapple Group marketed Canada Dry as containing “real ginger” when the beverage actually relies on chemical flavoring that mimics ginger taste without providing any of the root’s health properties. The company settled the case.
Why It Won’t Help Your Nausea
Reaching for ginger ale when you feel nauseous is one of those habits passed down through generations, but the science doesn’t support it. Real ginger does work for nausea. Fresh ginger root contains a compound called gingerol that reduces inflammation and has antioxidant properties. Clinical studies show it helps with morning sickness, motion sickness, and chemotherapy-related nausea at doses typically around 1,000 milligrams per day, which is roughly equivalent to one teaspoon of freshly grated ginger.
Canada Dry doesn’t come close to that threshold. The trace amount of ginger extract in the formula is nowhere near the 600 to 2,500 milligrams used in clinical trials. As the Cleveland Clinic puts it, most commercial ginger ales either don’t contain natural ginger at all or don’t contain enough to offer significant relief. The carbonation and sugar can actually make bloating, gas, and indigestion worse.
The Sugar Problem
At 33 grams of sugar per can, Canada Dry is in the same ballpark as Coca-Cola (39 grams) and Pepsi (41 grams). The American Heart Association recommends no more than 25 grams of added sugar per day for women and 36 grams for men. One can of Canada Dry pushes you to (or past) that limit before you eat anything else.
The sweetener is high fructose corn syrup, which your liver processes differently than other sugars. Fructose is metabolized almost entirely in the liver, where it promotes new fat production and can impair the liver’s ability to burn existing fat. Chronic consumption of high fructose from soft drinks has been linked to insulin resistance, fatty liver disease, and obesity. One study found that participants who drank sugary beverages containing high fructose for six months showed measurable increases in liver fat. Over time, this fat accumulation can progress to chronic liver disease, with severity tied directly to how much fructose a person consumes.
Fructose also triggers a drop in cellular energy and a rise in uric acid, which creates oxidative stress and blunts your body’s sensitivity to insulin. This cascade can contribute to metabolic syndrome, a cluster of conditions that raises your risk for heart disease and type 2 diabetes.
Carbonation and Digestion
Some people worry that the carbonation itself causes digestive problems. The evidence is more nuanced than you might expect. Carbonated beverages do cause a brief dip in the pH of your esophagus and can temporarily relax the valve between your esophagus and stomach. But a systematic review of the available research found no direct evidence that carbonated drinks promote or worsen acid reflux disease. Plain sparkling water, without the sugar and additives, is largely harmless for most people’s digestive systems.
That said, if you’re already dealing with bloating or gas, the combination of carbonation and 33 grams of sugar is more likely to make things uncomfortable than to calm your stomach.
The Preservative Question
Sodium benzoate, the preservative in Canada Dry, prevents bacterial and mold growth. It has FDA “generally recognized as safe” status, and your body doesn’t store it. Your liver converts it into a compound called hippurate, which gets filtered out through your kidneys. The permissible daily intake is up to 5 milligrams per kilogram of body weight, and the amount in a can of ginger ale falls well within that range.
There is one caveat worth knowing: sodium benzoate can react with vitamin C (citric acid is present in Canada Dry, though it’s not the same as vitamin C) to form benzene, a known carcinogen. This reaction happens primarily under heat and light exposure, and regulatory agencies monitor benzene levels in beverages. At normal consumption levels, the preservative is not a meaningful health concern for most people.
Better Ways to Get Real Ginger
If you’re drinking Canada Dry because you like the taste, that’s fine in moderation, the same way any soda is fine occasionally. But if you’re drinking it because you think it’s healthier than other soft drinks or because you want ginger’s actual benefits, you have much better options.
- Fresh ginger root: Grate about half an inch into hot water for a simple tea, or add it to sparkling water with a small amount of honey. One teaspoon of freshly grated ginger delivers roughly 1,000 milligrams, the dose shown to help with nausea.
- Ginger capsules: Available at most pharmacies, these deliver standardized doses (typically 250 to 500 milligrams per capsule) without any sugar.
- Reed’s Extra Ginger Brew: Contains 25 grams of fresh ginger per bottle, enough that you can taste the burn. Still contains sugar, but delivers actual ginger.
- Ginger beer (craft varieties): Brands like Bundaberg use real ginger root in their brewing process, though sugar content varies and can still be high.
The simplest approach is the DIY route: grate fresh ginger into sparkling water and sweeten lightly to taste. You get real gingerol, minimal sugar, and carbonation if you want it.
