About Lemon
Lemons are citrus fruits that originate from South Asia, particularly northeastern India, and are now widely grown in Mediterranean regions, the Americas, and parts of Asia. Known for their tangy, acidic flavor and bright yellow color, lemons are a staple in many cuisines worldwide, from Mediterranean dishes to Asian recipes. Nutritionally, lemons are low in calories (29 calories per 100g) and rich in vitamin C (53 mg per 100g), making them a powerful source of antioxidants. They also provide dietary fiber (2.8g), small amounts of essential minerals like calcium (26 mg) and iron (0.6 mg), and very little fat (0.3g). Due to their invigorating taste and health-enhancing properties, lemons are often used in beverages, dressings, baked goods, and marinades, adding both flavor and nutrition to meals.
