For those looking to reduce their sugar intake, jar sugar substitutes may be a helpful alternative. These products come in a variety of forms such as granulated, liquid, and powdered options. They are made from natural sweeteners such as stevia, monk fruit, or erythritol, and can be used in place of sugar in baking, cooking, or adding to drinks. While it is still advised to consume these substitutes in moderation, they can help stabilise blood sugar levels and reduce the risk of tooth decay compared to regular sugar.
