Lemons can also be used for cleaning. The citric acid in lemon juice can kill bacteria and other germs.
Exactly where lemons came from isn't known. But there's documented evidence of its value from almost 2,000 years ago. The lemon tree grows in subtropical and tropical areas and can grow 10-20 feet tall. Most are grown in Mediterranean countries, as well as China, India, Mexico, Argentina, and Brazil. They also grow in California, Arizona, Texas, and Florida in the U.S. You can find fresh lemons year-round in supermarkets.

Are lemons a fruit?
Yes. In biology, a fruit is the part of a plant with seeds.
Types of Lemons
The most commonly grown lemon in the U.S. is the Eureka lemon. The Lisbon lemon is also popular.
You may also come across the Meyer lemon, a smaller, sweeter lemon that may have gotten its start as a cross between a lemon and a mandarin orange. These can make good house plants, but you'll need to bring them inside in the winter if you're not in a tropical climate.
When you buy lemons, look for those that are bright and have an even color and a smooth, blemish-free surface. Lemons should be firm but not too hard. Those with thinner skin tend to be juicier. You can tell if your lemon is ripe by checkingits weight. It's ripe when it feels heavy for its size.
While you can find lemons year-round at your grocery store, peak seasonalityin the U.S. is late winter to early spring and summer depending on the variety and the climate where they're grown. Store them in the refrigerator so they'll last longer than at room temperature.
Health Benefits of Lemons
The vitamins, fiber, and plant compounds in lemons can be part of a healthy diet. It's not common to actually eat a fresh lemon--they're too sour for most people's tastes--unless you're using preserved lemons. But you can also eat lemons with a variety of foods.
Lemons can also provide important health benefits like:
Vitamin C
Lemons contain about 35 milligramsof vitamin C, which is over half the amount ofvitamin C needed in your daily diet. Vitamin C is an antioxidant, which helps protect cells from damage. Vitamin C also helps your body make collagen for your skin, helps your body absorb iron, and supports your immune system. Citrus fruits are some of the best food sources of vitamin C.
Lemon also contains a high level of dietary fiber, but you don't get fiber from juice.
Weight management
The pectin fiber found in lemons expands once it is ingested, making you feel full sooner and longer. Lemon water is often touted as an effective tool in weight loss andweight management.While there's nothing wrong with drinking water, there's nothing magical about adding lemon to water for weight control. Also, drinking water may keep you full and help you avoid snacking as effectively as sipping lemon water.
Anemia prevention
Lemon can help your body absorb more iron from plant-based foods in your diet. Maintaining proper iron levels helps preventanemia. Anemia is a lower-than-average number of red blood cells, which often happens as a result of iron deficiency.
Kidney stone prevention
Lemons get their sour taste from their abundance of citric acid. Some studies show that citric acid may help prevent the formation ofkidney stones.
Enhances your complexion
The vitamin C in lemons helps to form collagen, a protein that supports your skin. The vitamin C, folic acid, vitamin B, and minerals in lemonmay helpto improve your acne, oily skin, blackheads, and dandruff.
Vitamin C is also a powerful antioxidant. Antioxidants help to prevent cell damage caused by oxidative stress, which can enhance skin health.Early research suggests that drinking a beverage made with lemon juice may improve your complexion and slow the aging of your skin.

Antibacterial effects
Lemon juice has antibacterial and antifungal properties. The plant compounds in lemon juice concentrate effectively inhibited the growth of salmonella, staphylococcus, and candida infections in one study. It was also effective against one particular antibiotic-resistant bacteriathatcauses pneumonia and blood infections.
Cancer prevention and treatment research
Lemon juice is a valuable source of nutrients called flavonoids. These are antioxidants, which help protect cells from damage that could lead to cancer. But lemon juice hasn't been studied for cancer prevention in people. While a healthy diet may help lower the risk of cancer, no one food has been shown to prevent cancer.
Lemon juice is not part of cancer treatment. But scientists have found tiny nanoparticles in lemon juice that--in lab tests on cells--inhibited cellreproduction and activated cancer cell death. This is extremely early research that's more about searching for new cancer treatments and isn't based on the lemon juice you'd get in your diet.
Immune system support
One lemon can offer about half of yourrecommended daily value of vitamin C, which contributes to immune system defense and may help the body fight infection. Lemons also contain citrusflavonoids. These antioxidants fightfree radicals, haveanti-inflammatory effects, and can reduce your risk of brain disease and other degenerative diseases.
