Monk fruit is a small, green fruit originally cultivated in Southeast Asia. It is a popular natural sweetener due to its extremely low calorie and high antioxidant content. Monk fruit is also known by several other names, including luo han guo, Buddha fruit, and longevity fruit. The Chinese call it "la han qua," while in Thailand it is referred to as "khan toi." The fruit's sweet components, known as mogrosides, are extracted and sold as a sweetener under the brand name Lakanto. Other names for monk fruit sweetener include Siraitia grosvenorii extract, monk fruit extract, and lo han kuo extract. Regardless of what it is called, monk fruit is a great alternative to processed sugars for those looking for a natural and low calorie sweetener.
