Kvass is a traditional fermented drink that carries both potential benefits and certain risks, especially for people with specific health conditions. It is not advised for individuals with diabetes mellitus, chronic hypertension, or gastrointestinal disorders such as acute gastritis and peptic ulcers to consume kvass in large amounts or without medical supervision. This guidance comes from endocrinologists who emphasize careful consideration of how kvass might affect blood sugar, blood pressure, and stomach lining. The caution is particularly important when kvass is part of a broader dietary pattern that already demands careful nutrient management. For those living in Canada or the United States, discussing kvass intake with a healthcare professional can help tailor recommendations to personal health goals and medical history (Source: endocrinologist consultation).
