A medically reviewed health analysis indicates that chai tea may aid in maintaining healthy blood sugar levels when made with black tea and spices like cinnamon and ginger. Traditional unsweetened chai typically has under 2 grams of carbohydrates per serving, whereas many 16-ounce café-style chai lattes can contain 30 to 40 grams of added sugar. Experts emphasize the importance of preparation, particularly for individuals with diabetes, who must limit added sugars and be aware of potential interactions with diabetes medications when regularly consuming chai.
