This citrus fruit originated in Southeast Asia but is now grown in tropical and temperate climates all over the world. California is the leading producer in the United States. Acidic, with a sour or tart flavor, lemons are used to flavor both sweet and savory dishes, as well as candy and drinks.
Lemons are rich in vitamin C, a powerful antioxidant that offers health benefits including promoting a healthy immune system and reducing the risk of heart disease, hypertension, cancer, and other degenerative diseases. To provide greater nutritional value, lemon juice can be added to processed foods, beverages, packaged desserts, and other food products.
