Yes, lime juice has sugar, but its sugar content is less than 0.5g per 1 oz.
Limes are better known for their tart flavor, which is mainly due to the presence of citric acid rather than sugar.
Variables in the Sugar Content of Limes
Limes are delicious and easy to grow in tropical climates because they are the most cold-intolerant of all citrus fruits. Persian limes and Tahitian limes are the most popular varieties cultivated in the warmer climates of Florida, California, Arizona, and Texas, with the Key lime produced in smaller quantities.
Each of these species has unique characteristics and varying sugar content. The sugar content in limes is influenced by factors such as the lime variety, growing conditions, and maturity at harvest.
For example, Persian limes are typically less acidic and slightly sweeter compared to the more common smaller, more acidic, and more aromatic Key limes. Key limes are known for their tartness and are often used in dishes like Key lime pie.
How Much Sugar in Lime Juice?
While limes do contain some sugar, it is much less than other fruits such as oranges and grapes.
A 1-ounce serving of pure lime juice only contains around 0.5 grams of sugar, compared to an ounce of orange juice, which contains around 2.9 grams, and pure grape juice, which contains about 4.75 grams of sugar per ounce.
It's important to note that the sugar in pure lime juice is naturally occurring and not added sugar, which might not be true for some commercially produced lime juice brands.
The 4.09 grams of sugar in an 8-ounce serving of 100% lime juice comprise 1.16 grams of sucrose, 1.45 grams of glucose, and 1.46 grams of fructose.
As such, lime juice is an excellent choice for those looking to limit their sugar intake. Furthermore, limes are rich in vitamin C, antioxidants, minerals, and other nutrients. They may help boost immunity, reduce the chance of heart disease, prevent kidney stones, aid iron absorption, promote healthy skin, and lower the risk of certain cancers.
