Sweeteners are used to improve the taste of foods and beverages by adding a sweet flavor. They can be natural or artificial, and some have the added benefit of containing fewer calories compared to refined sugars. Stevia (Stevia rebaudiana) is a popular natural sweetener, derived from the leaves of the stevia plant, and is up to 200 times sweeter than sugar while being virtually calorie-free. It is often used as an alternative for those looking to reduce sugar intake or maintain stable blood sugar levels.

Another natural sweetener is licorice root (Glycyrrhiza glabra), which has a naturally sweet flavor that can be used in herbal teas or formulations. Monk fruit (Siraitia grosvenorii), also known as luo han guo, is another low-calorie natural sweetener that is becoming increasingly popular due to its sweetening power without impacting blood sugar significantly.

Some herbs, like fennel (Foeniculum vulgare) and anise hyssop (Agastache foeniculum), have a naturally sweet flavor that can be used to enhance the taste of teas or culinary dishes without adding concentrated sugars.

Natural sweeteners offer a more wholesome alternative to refined sugar and artificial sweeteners, making them a great choice for those looking to maintain a healthy diet while still enjoying sweetness.
