A glass of Coke, on the other hand, contains 35g - that's about seven teaspoons. But ginger beer's cousin, ginger ale, was found to be the fizzy drink with the lowest amount of sugar on average. A glass contains around 22.9g, according to the findings - but that's still 4.9 teaspoons.
While eating ginger is healthy, the ginger in ginger ale is just flavoring. Not even close. Non diet ginger ale has a ton of sugar, over 10% by weight. The diet ginger ale is better than diet coke, it has fewer chemicals in it, or atleast some less harmful chemicals over diet coke.
Despite the health benefits of ginger, ginger ale still falls into the category of soft drinks or sodas, so it's not a health food. If you choose to consume ginger ale, it's best to do so in moderation as part of an overall healthy diet. Many commercial ginger ale drinks use artificial ginger flavoring.
