About Lemon juice
Lemon juice is the liquid extract from the pulp of lemons, a citrus fruit native to northern India. It holds a prominent place in culinary traditions across the world, particularly in Mediterranean, Middle Eastern, and Southeast Asian cuisines. Known for its tangy flavor and high acidity, lemon juice is a versatile ingredient used in beverages, dressings, marinades, and desserts. Nutritionally, it is low in calories (about 4 calories per tablespoon) and provides small amounts of essential nutrients, including vitamin C, potassium, and trace amounts of B vitamins. Its antioxidant properties and citric acid content also contribute to its health benefits and culinary uses, such as tenderizing meats and preventing enzymatic browning in fruits and vegetables.

Common Questions About Lemon juice Nutrition
What is the nutritional content of lemon juice?
Lemon juice is low in calories, with about 6 calories per ounce (approximately 30 mL). It contains minimal protein and fat but is a good source of vitamin C, providing about 18 mg per ounce, which is roughly 20% of the recommended daily intake. It also contains small amounts of potassium and calcium.
Can I drink lemon juice on a keto or low-carb diet?
Yes, lemon juice is compatible with both keto and low-carb diets as it is very low in carbs. One ounce of lemon juice contains around 1-2 grams of carbohydrates, most of which come from natural sugars. It can be used to add flavor to meals and beverages without significantly affecting carb intake.
What are the health benefits of consuming lemon juice?
Lemon juice is rich in vitamin C, which supports immune health, skin health, and antioxidant protection. It may also aid digestion due to its acidity and potential to stimulate stomach acid production. However, its high acidity can be harsh on tooth enamel if consumed in excess or undiluted, so rinsing your mouth afterward is recommended.
How much lemon juice should I consume daily?
There is no strict guideline, but consuming up to 2-4 tablespoons (1-2 ounces) per day, either in water or cooking, is generally safe and offers health benefits. Drinking lemon juice diluted in water is a popular way to enjoy it without overexposure to its acidity.
How does lemon juice compare to lime juice in nutrition and flavor?
Lemon juice and lime juice have similar nutritional profiles, both being low in calories and rich in vitamin C. Lemon juice has a slightly sweeter and less tart taste, making it more common in beverages, while lime juice is tarter and more acidic, often used in savory dishes and cocktails. Both can be substituted for one another in most recipes, depending on flavor preference.
