Regular ginger ale is generally not low FODMAP. Most commercial brands are sweetened with high fructose corn syrup, which contains excess fructose, a key FODMAP trigger. However, the answer changes depending on the type of sweetener used, whether the drink is diet or regular, and how much you consume.
Why Regular Ginger Ale Is Problematic
The main issue with standard ginger ale isn’t the ginger. It’s the sweetener. In the United States, most major ginger ale brands (think Canada Dry, Schweppes) use high fructose corn syrup. This sweetener delivers fructose in excess of glucose, which is exactly the type of sugar the low FODMAP diet restricts. Fructose in excess of glucose is poorly absorbed in the small intestine, and for people with IBS, that unabsorbed fructose gets fermented by gut bacteria, producing gas, bloating, and discomfort.
The Canadian Digestive Health Foundation specifically lists ginger ale alongside cola, Sprite, and energy drinks as beverages that contain problematic fructose levels. Even a single can could push you past the low FODMAP threshold for fructose, particularly during the elimination phase of the diet.
Cane Sugar Brands: A Better Option
Ginger ales sweetened with cane sugar (sucrose) are a different story. Sucrose breaks down into equal parts fructose and glucose, so there’s no excess fructose to trigger symptoms. Several brands use cane sugar instead of high fructose corn syrup:
- Bruce Cost Ginger Ale uses just carbonated water, organic cane sugar, fresh ginger, and citric acid
- Reed’s Ginger Ale uses pressed organic ginger and cane sugar
- Fever-Tree Ginger Ale is made with real sugar
- Boylan Ginger Ale uses cane sugar instead of high fructose corn syrup
These brands are more likely to be tolerated on a low FODMAP diet, though portion size still matters. A standard serve (around one glass) is a reasonable starting point. Always check the ingredient list, because formulations change and some products vary by region.
What About Diet Ginger Ale?
Diet ginger ales sweetened with aspartame or sucralose are generally considered low FODMAP. These artificial sweeteners don’t contain fermentable sugars, so they shouldn’t trigger the same gut response as fructose. The Canadian Digestive Health Foundation notes that diet sodas using sucralose and aspartame are low to moderate FODMAP and should not trigger IBS symptoms.
The sweeteners to watch out for in sugar-free drinks are sugar alcohols (polyols), the “P” in FODMAP. Sorbitol and xylitol sometimes show up in sugar-free beverages marketed to people with diabetes. If you see these on a diet ginger ale label, that product would not be low FODMAP. Stick to versions sweetened with aspartame or sucralose.
Carbonation Can Still Cause Symptoms
Even if you choose a FODMAP-friendly ginger ale, the bubbles themselves may be a problem. Monash University, the team behind the low FODMAP diet, notes that carbonated drinks can distend the stomach and intestines, leading to bloating and discomfort in people with IBS. At least one major IBS guideline recommends reducing fizzy drink intake to help manage symptoms. This isn’t a FODMAP issue per se, but it’s a practical one. If you already deal with bloating, carbonation can add to it regardless of the sweetener used.
Drinking smaller amounts, sipping slowly, and letting the drink go slightly flat before consuming it can all help reduce the amount of gas reaching your gut.
Don’t Count on Ginger Ale for Digestion
Many people reach for ginger ale hoping the ginger will settle their stomach. Real ginger does have some evidence behind it. Research published in the World Journal of Gastroenterology found that ginger can enhance stomach contractions and speed up gastric emptying, possibly through its interaction with serotonin receptors in the gut. That’s the basis for ginger’s reputation as a nausea remedy.
The problem is that most commercial ginger ales contain very little to no actual ginger root. They’re flavored with ginger extract or artificial ginger flavoring at concentrations far below what’s been studied for digestive benefits. If you want the gut-soothing properties of ginger on a low FODMAP diet, fresh ginger steeped in hot water (ginger tea) is a more reliable choice. Fresh ginger in small amounts is considered low FODMAP, and you’ll get a much higher concentration of the active compounds than any commercial soda provides.
Quick Guide to Choosing Ginger Ale on Low FODMAP
- Avoid: Regular ginger ale made with high fructose corn syrup (most major U.S. brands)
- Better: Ginger ale made with cane sugar (Bruce Cost, Reed’s, Fever-Tree, Boylan)
- Also fine: Diet ginger ale sweetened with aspartame or sucralose
- Avoid: Sugar-free ginger ale containing sorbitol, xylitol, or other sugar alcohols
Read the ingredient label every time. “Natural flavors” won’t tell you much, but the sweetener listed will tell you almost everything you need to know about whether that particular ginger ale fits your low FODMAP plan.
