Health benefits of lemons

Lemons are citrus fruits that offer a wide range of health benefits. Some of the health benefits of lemons may include, but are not limited to,

High in Vitamin C: Lemons are an excellent source of vitamin C, a powerful antioxidant that helps boost the immune system, fight infections, and protect against the damaging effects of free radicals. According to a study, lemons are rich in vitamin C which aids in enhancing various health benefits including fatigue and lowering cholesterol.1

Promotes Digestive Health: The citric acid in lemons helps to stimulate the production of digestive juices, which can aid in digestion and alleviate symptoms of indigestion.

Supports Heart Health: The potassium in lemons can help control  blood pressure, reduce the risk of heart disease, and improve cardiovascular health.

Anti-inflammatory Properties: Lemons contain flavonoids and other compounds that have anti-inflammatory properties, which can help reduce inflammation throughout the body.

Good for Skin Health: The vitamin C and antioxidants in lemons help to reduce the signs of ageing, promote healthy skin, and protect against damage caused by free radicals.

Helps to Detoxify the Body: Lemon juice has a natural water-balancing effect, which can help flush out toxins from the body and promote healthy liver function.

Controls weight gain: Small amounts of lemon juice mixed in a glass of lukewarm water can work wonders in helping you lose a few pounds. Lemons can aid in controlling weight loss because they contain a compound called pectin. Pectin is a type of fibre that helps keep you full for a long period of time and prevents you from unhealthy snacking. Some animal studies showed that lemon polyphenols can have an effect on suppressing diet-induced obesity and improving insulin resistance and lipid metabolism. Though these studies were only conducted on animals, clinical trials are still required to acquire more information related to their effectiveness in humans.2

How much is enough?

Side effects and how much to consume or other information you can add

Lemons are generally considered safe for consumption and have very few side effects when consumed in moderation. However, excessive consumption of lemons or lemon juice may lead to some potential side effects, which may include:

Tooth erosion: Lemons are highly acidic, and frequent consumption of lemon juice can erode tooth enamel (a thin outer layer that lines the tooth). Excessive intake may cause tooth sensitivity and decay. To prevent tooth erosion, doctors recommend limiting the amounts of acid-containing foods and beverages and waiting at least an hour before brushing your teeth, so the enamel can re-harden.

Gastrointestinal issues: In some individuals, consuming large amounts of lemon juice can cause gastrointestinal problems like acid reflux, heartburn, and stomach cramps.

Skin irritation: Since the nature of lemon juice is acidic, it may cause skin irritation and dryness in some people.

Kidney stones: Consuming excessive amounts of lemon juice may increase the risk of developing kidney stones, especially in individuals who are prone to developing them.

Allergic reactions: Some individuals may be allergic to citrus fruits such as lemons. Consuming them may trigger allergic reactions in them like hives, itching, and sometimes swelling.

May trigger headaches: Lemon juice is considered to contain high amounts of tyramine. It is best to limit lemon juice consumption if you are sensitive to tyramine, as drinking lemon juice may trigger migraines and headaches.
