Sweet and sour sauce is a Chinese-American style sauce made with sugar, vinegar, and fruit juices. It is extremely high in carbohydrates due to added sugars and starch thickeners. Sweet and sour sauce is not keto-friendly and is not suitable for diabetic-friendly eating. Sugar-free versions or vinegar- based sauces are preferred alternatives.
