Lemons are a popular fruit that people use in small quantities to add flavour to food. However, they rarely consume them alone due to their intense, sour taste. Lemons give flavour to baked goods, sauces, salad dressings, marinades, drinks, and desserts. They are also a good source of vitamin C, fibre, and various beneficial plant compounds. These nutrients are responsible for several health benefits. In fact, lemons may support heart health, weight control, and digestive health.
