Lemon Juice Benefits & Uses
Lemon juice is good for you because it can help boost your immunity, improve skin and hair health, and aid digestion. It is an effective fat burner and has anticancer potential. Let us look at the health benefits and uses in detail.
Treats Respiratory Infections
Lemon juice diluted in warm water, sweetened with honey, is an age-old remedy for sore throat. A 2017 study published in the Advances of Biotechnology and Microbiology journal found that lemon juice with honey can be used as alternative medicine in the treatment of respiratory tract infections. It inhibits the activity of Streptococcus pneumoniae and Streptococcus pyogenes, two kinds of bacteria that cause severe infections. Also, vitamin C in the freshly squeezed juice strengthens the immunity system.
Pure lemon juice may be too harsh on the skin due to its acidic nature, but a mixture of honey and lime juice is a hydrating and safe face mask with a natural bleaching effect on the skin. The blend is effective against Candida albicans and has a strong antibacterial and antifungal profile. You can use this face mask for an instant glow! For a simple homemade body scrub, mix this juice with sea salt and sugar.
Lemon juice is a natural astringent with antimicrobial properties. Research published in the International Journal of Science Inventions Today reveals that lemon juice contains L-ascorbic acid which helps fight acne. It is highly effective against Propionibacterium acnes. Furthermore, it helps remove excess oil while also exfoliating the skin. The best way to use the juice for acne is to dip a Q-tip in the liquid, apply it on the acne-affected area, and leave it overnight. The juice, with its skin lightening properties, can also help lighten acne scars.
Lemon juice can be used to reduce grey hair, according to a report in the International Journal of Ayurvedic and Herbal Medicine. Coconut oil and lemon juice is a popular remedy for grey hair; however, grey hair is caused due to a lack of pigment. Nevertheless, the citrus juice acts as a natural antiseptic and helps keep hair and the scalp clean.
Citrus limonoids, present in lemon juice, are rare natural compounds that have anticancer potential. According to a study published in the American Chemical Society journal, limonoids slow down cell proliferation and induce apoptosis. In animal studies, these powerful compounds were shown to stop cell metastasis. Another 2017 animal study found that a blend of garlic and lemon juice extract had an anti-cancer effect. Further human studies are required to explore the therapeutic potential of the juice against cancer.
Lemon juice has antibacterial properties, as proven by a study published in the Journal of Oral Hygiene Health. The study evaluated the effectiveness of the juice as an oral rinse as compared to a commercially available mouthwash. The citric acid in it significantly helped suppress bacterial growth. In calibrated quantities, the juice can also be used as a disinfectant, inhibiting Vibrio cholerae in drinking water. Vibrio cholerae is a gram-negative bacterium that can cause cholera.
Prevents Kidney Stones
Drinking the juice of two lemons diluted in water daily can potentially reduce the risk of kidney stones. According to the National Kidney Foundation, the stone formation is inhibited due to the presence of citrate, a salt in citric acid, which binds with calcium. However, other citrus juices like orange juice can also work. Furthermore, a 2015 study reveals that lemon juice thins the bile produced by the liver and helps it flow more easily, allowing the body to detox in a more efficient manner. In turn, this improves hepatic enzyme action and prevents gallstone formation.
Aids Weight Loss
Lemon juice diluted with water, also known as lemon water, is well-known as a fat burner. The results of an animal study, published in the Journal of Clinical Biochemistry and Nutrition, revealed that the polyphenols in the juice inhibited weight gain and fat accumulation. An ancient Ayurvedic recipe for obesity calls for drinking a glass of warm water with 10 ml of honey and 5 ml of lemon juice early in the morning.
Helps Manage Cholesterol
Lemon juice is used in folk medicine to improve heart health, due to its lipid-lowering properties. In an animal study reported in the Comparative Clinical Pathology 2015, laboratory rats fed with a high-cholesterol diet were administered the juice. There was a significant reduction in plasma total cholesterol, triglyceride levels, and LDL (bad) cholesterol levels. It also helped increase HDL (good) cholesterol levels.
Lowers Blood Pressure
A study conducted in Japan on middle-aged and older women showed that consuming lemon juice daily, coupled with walking, helped lower systolic blood pressure.
Lemon juice cleanses are known to help detox the system and keep the liver, gut, and kidneys healthy. In her book “The Lemon Juice Diet“, health writer Theresa Cheung says the juice’s low glycemic index helps keep energy levels stable while firing up the body’s metabolism.
Enhances Nutrient Absorption
A squeeze of lemon on your salad greens or meat helps the body absorb nutrients, especially iron. Also, a 2016 report published in the Natural Science journal found that green tea, with lemon, has a greater phenolic content than just the tea alone. Free radical scavenging activity was also shown to have increased.
Lemon juice can help protect the liver from the damage caused by chronic alcohol consumption. According to the BioMed Research International 2017 issue, the flavonoids in it aid in detoxing harmful metals from the blood. Additionally, the lemon essential oils and pectin have an insulating effect on the stomach and intestine.
It works can be effective to clean grout, wooden surfaces, as well as grease stains from clothes. To make a handy household cleaner, mix the juice of a medium-sized lemon with water in a spray bottle. It helps remove food odors from the refrigerator and oven too.
You can use lemon juice or lemon peels to repel ants and mosquitoes. Sponging your pet with water mixed with the freshly squeezed juice of the lemon can help get rid of fleas and give them a lovely fresh fragrance.
How to Juice a Lemon?
You may require lemon in many preparations like juices or soups and in DIY skincare routines. It is great to know how to juice it so that you do not have to wait for your next grocery trip to shop for a bottled version. Here are the steps to juice a lemon:
- Take the lemon and roll it under your palm while it is on the table. This will ensure that the juice capsules open up and you get the most out of this citrus fruit.
- Once, that is done, cut the lemon into two halves lengthwise.
- Now put one half of the lemon on a mesh strainer in such a way that the lemon rind is facing you. Make sure to keep a cup or a bowl beneath the strainer.
- Holding the same position, take the lemon half a bit above the strainer and squeeze it. You will see the juice pouring into the bowl.
- Now, toss it wherever you like and enjoy it!
Note: If you have kept your lemon in the refrigerator, then remove and keep it at room temperature for about 15 minutes. alternatively, you can microwave the lemon for about 15 seconds to bring it to normal temperature if you are in a hurry.
How Much Juice is in One Lemon?
A lot of recipes call for the juice of a lemon. However, lemons differ in size depending on the region they are produced in. There are 4 to 5 medium-sized lemons in 1 pound. On average, 2-3 tablespoons of lemon juice equals one lemon. A bigger lemon will give a 1/4 cup (60 ml) of lemon juice, about 4 tablespoons. If a recipe calls for the juice of 1 lemon, you can substitute it with 2 tablespoons of bottled lemon juice as it has a concentrated flavor. Also, 1 lemon has 1 tablespoon (15 ml) of lemon rind or lemon zest in it.
Older lemons may not give as much as juice as they dry up. To get the maximum juice from a lemon, microwave it for 10-20 seconds. This will help loosen the lemon and you can squeeze out the juice more easily. But make sure to not overdo as the bitter residue may also get squeezed out with the juice and make your recipe taste bad.
Does Lemon Juice Go Bad?
Lemon juice can go bad if it is not stored properly. Freshly squeezed juice can go bad in a day if stored at room temperature. You can tell if it has gone bad if it tastes or smells extremely sour or if it appears dark yellow. While the citric acid in it can inhibit bacteria growth, it will eventually spoil and get mold.
How to Store Lemon Juice?
Freshly squeezed juice of the lemon can last for up to a day in the refrigerator. The best way to store the juice is to freeze it in ice cube trays. You can remove the ice cubes and store it in a freezer bag, and pop an ice cube whenever you need it. This way your juice can last longer.
For store-bought lemon juice, it is advisable to stick to the expiry dates to be safe. Once opened, it usually lasts for 6 to 12 months in a refrigerator or the pantry cupboard, unless mentioned otherwise. However, before using an opened lemon juice bottle for baking, it is best to check it for spoilage.
