💎 Key Nutrients
Raw Lemon Juice Nutrition per 100g
The USDA record uses 1 cup (244 g) as its serving: 61 calories, 0.9 g protein, 0.6 g fat, 21.1 g carbohydrate, 5.9 g total sugar, 1 g fiber and 94.4 mg vitamin C. Dividing those values by 2.44 gives a calculated 100 g reference of about 25 calories, 0.37 g protein, 8.65 g carbohydrate, 2.42 g sugar, 0.41 g fiber and 38.7 mg vitamin C. The calculation is for raw, unsweetened juice.
Juice, Lemon Flesh and Lemonade Are Different Entries
This page describes juice squeezed from raw lemons. It should not be used for a lemon segment with pulp, lemon peel, concentrate or prepared lemonade. Pulp and peel change the water, fiber and nutrient amounts; sugar or syrup changes the carbohydrate value. Match the database item to what you actually weigh or pour.
How to Use the Numbers in a Recipe
For a smaller amount, scale the cup values by weight. For example, 15 g of raw juice is approximately 3.8 calories and 5.8 mg vitamin C using the calculated per-100 g reference. Juice, oil, salt and sweeteners added to a dressing or drink must be counted separately. A kitchen scale is more reproducible than estimating a lemon by size.
Storage and Practical Uses
Use raw juice in dressings, marinades, sauces and drinks. Keep freshly squeezed juice covered and refrigerated, and discard it when it develops mold, gas, an off odor or an unusual appearance. Bottled products may contain preservatives or added ingredients, so their label is the better source for that product. Lemon juice is acidic; avoid treating it as a substitute for medical care.
