Lime juice contains approximately 1 gram of sugar per tablespoon (15 ml), making it a low-sugar option for flavoring drinks and dishes.
Lime juice is a popular citrus ingredient used in drinks, marinades, and recipes worldwide. But how much sugar does it actually contain? The answer might surprise you. Fresh lime juice contains minimal natural sugars – about 0.7g per ounce (30ml) – making it an excellent low-sugar alternative to sweetened beverages.
The Sugar Content of Lime Juice
Pure lime juice from fresh limes contains very little sugar naturally. Here’s the breakdown:
| Measurement | Sugar Content |
|---|---|
| Per 1 oz (30ml) | ~0.7g sugar |
| Per medium lime (2 tbsp juice) | ~1.1g sugar |
| Per 100g | 1.7g sugar |
Compared to other citrus juices, lime juice is significantly lower in sugar:
- Orange juice: ~9g sugar per 100g
- Grapefruit juice: ~6g sugar per 100g
- Lemon juice: ~2.5g sugar per 100g
Why Lime Juice Has Minimal Sugar
Limes contain less sugar than other citrus fruits because:
- They’re more acidic (pH 2.0-2.4)
- They have higher concentrations of citric acid
- They develop less sugar during ripening
Nutritional Benefits Beyond Sugar Content
While low in sugar, lime juice packs impressive nutritional benefits:
Vitamin C Powerhouse
One medium lime provides 22% of your daily vitamin C needs. This antioxidant supports immune function and skin health.
Other Key Nutrients
Lime juice contains small amounts of:
- Iron (helps oxygen transport)
- Potassium (supports heart health)
- Vitamin B6 (aids metabolism)
Antioxidant Properties
Limes contain flavonoids like hesperidin and naringenin that fight inflammation and may reduce disease risk.
Commercial Lime Products vs. Fresh Juice
While fresh lime juice is low in sugar, commercial products often add significant sweeteners:
Lime Cordials and Mixers
Products like Rose’s Lime Cordial contain up to 30g sugar per 100ml – nearly 50 times more than fresh juice. These often use high fructose corn syrup and artificial flavors.
Sparkling Lime Waters
Some brands like Spindrift use real lime juice with minimal added sugar, while others add significant sweeteners.
Bottled Lime Juice
Check labels carefully – some contain added sugars or preservatives that increase the sugar content.
