Chai is traditionally made with black tea and spices such as cinnamon, ginger, cardamom, and cloves.
Because of this, many people assume it is always a healthy choice. However, that depends on what else is added to the drink.
That is according to Verywell Health, citing findings from several research studies.
Many chai lattes sold in cafés contain large amounts of sugar, syrup, and milk.

According to NutritionIX and Starbucks, a large chai latte can contain between 30 and 40 grams of added sugar. This can cause blood sugar levels to rise quickly.
Spices may have an effect
Research suggests that black tea contains compounds that may help the body use insulin more effectively.
A study published in Antioxidants also found that cinnamon and ginger may, in some cases, contribute to more stable blood sugar regulation in people with type 2 diabetes.
However, the findings are not consistent across all studies.

At the same time, caffeine may cause blood sugar levels to rise in some people.
According to DiaTribe, this is because the body can release stress hormones that increase the amount of sugar in the bloodstream.
Preparation makes the difference
People with diabetes can still enjoy chai, but it is important to choose an unsweetened version without syrup or large amounts of added sugar.
Verywell Health also recommends choosing a milk option that is low in carbohydrates.

Ultimately, it is not the chai tea itself that determines whether the drink is a healthy option.
When prepared without excessive added sugar, the black tea and spices may help support healthy blood sugar regulation.
