13 Wonderful Benefits of Grapefruit

The health benefits of grapefruits are many and nearly unmatched by any other fruit. A glass of chilled grapefruit juice, especially in summer, helps to boost levels of vitamin C in your body, which makes grapefruits the most nutritious fruit amongst various citrus fruits. Grapefruits are packed with the benefits derived from various nutrients and vitamins, including potassium and lycopene. Along with these, they also contain calcium, sugar, and phosphorous. In terms of culinary value, these fruits are considered a wonderful appetizer and are regularly included for breakfast as a refreshing and energizing start to the day.

What are Grapefruits?

Grapefruits are fruits that are high in fiber and low in calories, and they contain bioflavonoids and other plant chemicals that protect against serious diseases like cancer, heart disease, and the formation of tumors. Grapefruits increase the body’s metabolic rate, lower insulin levels, and give you a feeling of fullness. They assist the human body in fighting various conditions like fatigue, fever, malaria, diabetes, constipation, indigestion, urinary problems, excess acidity, and many more.

There are plenty of health benefits grapefruits have, which are also known to be powerful drug/poison eliminators. These fruits work as a natural antiseptic for external wounds and also function as a liver tonic. They contain a high amount of water, which helps in changing the complexion of the skin and increasing the body’s metabolic rate. The pulp and fiber of grapefruits have a healthy bulking action to our food intake, which aids in bowel movements and reduces chances of colon cancer. Grapefruits also help to quench thirst and thus, reduce the burning sensation that arises during fever. The Asia Pacific Journal of Clinical Nutrition suggests that the intake of grapefruit reduces the risk of developing prostate cancer.

Health Benefits of Grapefruits

The health benefits of grapefruits are as follows:

Suppress Appetite

Grapefruit works as an excellent appetite suppressant as compared to many other foods. It is said that smell of the grapefruit reduces the feeling of hunger, which is the reason why people often include grapefruits in their weight loss programs. The high amounts of fiber in these fruits can also satisfy hunger and help people avoid overeating, and stimulate cholecystokinin to be released, a hormone that regulates digestive juices and acts as a hunger suppressant.

Treat Influenza

Grapefruit is a valuable remedy for influenza since it helps to minimize acidity in the system. The bitter properties arising from an essence called ‘naringin’ in grapefruits tone up the system and the digestive process. Naringin is also considered a flavonoid, which is a powerful antioxidant. Antioxidants have antiviral, antifungal, antibacterial, anti-cancer, and anti-inflammatory qualities, making them one of the most important lines of defense in the immune system, protecting against influenza as well as many other serious conditions.

Treat Malaria

The juice or grapefruit itself contains valuable and natural ‘quinine’, which is advantageous for the treatment of malaria. Quinine is an alkaloid with a long history of treating malaria, as well as lupus, arthritis, and nocturnal leg cramps. It is not an easy component to find in many foods, so grapefruits are a beneficial and rare example. The quinine can be easily extracted from the fruits by boiling a quarter of grapefruit and straining the pulp.

Cure Fever

The pulp or the juice of grapefruit helps patients recover quickly from fever, and it reduces the burning sensation that occurs when the body reaches a high temperature. It is also known as a way to boost the immune system against cold and other common illnesses. Grapefruit juice, when combined with water, can quench thirst very quickly and can keep you hydrated for longer. Most of these benefits come from the high content of vitamin C in grapefruits, which acts as a general immune system defense system and can help the body in fighting against fever.

Reduce Fatigue

Grapefruits are beneficial in the treatment of fatigue as they can help you dispel your tiredness caused by routine or boring work. Drinking grapefruit juice can be a refreshing and delicious way to quickly boost your energy levels. Nootkatone is a very rare and important compound found within grapefruits and is probably its most valuable component in terms of extracting as an aromatic substance. Nootkatone improves energy metabolism in the body through AMPK activation. This results in higher endurance and boosted energy, increased weight loss, and a reduction in the chances of developing diabetes.

Treat Indigestion

Grapefruit is useful for indigestion. It is very light as compared to other foods and thus, acts immediately on indigestion by easing the heat and irritation caused in the stomach. It improves the flow of digestive juices, which eases the movement of the bowels and keeps your excretory system regulated. This is due to the presence of fiber and vegetative pulp in grapefruits that adds bulk to the bowels and regulates your excretory schedule, and grapefruit extract is also often used in modern medicine for these same reasons.

Promote Sleep

A glass of grapefruit juice, if consumed before going to bed, can promote healthy sleep and alleviate the irritating symptoms and repercussions of insomnia. This is due to the presence of tryptophan in grapefruits, the chemical we often associate with becoming sleepy after big meals. The levels of tryptophan in grapefruit juice enable us to nod off peacefully.

Control Diabetes

Diabetics can eat grapefruits as they can reduce the level of starch in the body. Intake of grapefruits can help them regulate the flow of sugar in their body, effectively handling the disease. Recent studies have shown this beneficial relationship between diabetes and grapefruits due to the flavonoid content of grapefruits, along with a number of other health benefits.

Reduce Acidity

Fresh grapefruit juice creates an alkaline condition in the intestines for proper digestion. The citric acid of the fruit is contained in the human body and thus it increases the efficiency of the alkalinity reaction after digestion. The juice extracted from the grapefruit is beneficial in preventing acid formation and many other diseases that arise due to the presence of excess acidity in the body.

Eliminate Constipation

A glass full of freshly squeezed grapefruit juice in the morning is a great remedy to control constipation. The juice stimulates the colon and other parts of the body relating to the digestive system. This is due to the stimulating effect of fiber on the secretion and stimulation of gastric juices that ease the constriction of the digestive tract and induce a bowel movement.

Remove Flatulence

10 to 20 drops of grapefruit juice, taken before all three meals of the day, can work as an appropriate pro-biotic and digestive enzyme and will relieve excess flatulence and stomach discomfort. Further research needs to be done on the exact mechanism behind this phenomenon, but again, people believe it relates to flavonoid content in citrus fruits like grapefruits.

Treat Urinary Disorders

Grapefruit juice is quite rich in potassium and vitamin C, so it is one of the best treatments for issues related to urination often caused by liver, kidney or heart problems. Furthermore, its high potassium content works as a vasodilator, meaning that blood vessels and arteries relax, reducing blood pressure and lessening the risk of heart attack and stroke. Also, increased levels of potassium have been associated with higher cognitive function because of increased blood and oxygen flow to the brain!

Other Benefits

Grapefruits are natural sources of medicine that help the body fight off various diseases. They are better than artificial pharmaceuticals to relieve your most basic health conditions. They enable the human body to regulate cholesterol, which means that they minimize the risk of cardiovascular diseases caused by high cholesterol. The Journal of Agricultural and Food Chemistry shows that consumption of grapefruit can reduce LDL cholesterol (bad cholesterol), as well as hazardous triglycerides.

Word of Caution: Despite all of these health benefits and the fact that sometimes grapefruits can be superior to other medicines in their efficacy, you must be very careful while taking medicines and consuming grapefruit juice at the same time. Certain chemicals in grapefruits, like naringin, and other less common compounds can negatively interact with various drugs and cause damage to your organ systems. Be sure to consult your doctor in terms of drug interactions with grapefruit juice in your diet before beginning any new treatment. You want to improve your health but sometimes doing it in too many different ways can hurt you!

I used to think grapefruit needed sugar until I learned to peel it and eat it in sections like an orange. Now I get all the fiber and don't have to fight it with a spoon.

I love the pink grapefruit as it is sweeter than the yellow one. I also love pomelos and I usually eat a whole one for breakfast whenever they are in season. They are very filling and taste great.

Grape Fruit is a great way to start the morning.
I love the taste and love the benefits.

Good morning, hope somebody can answer this for me. If a person who have heart conditions eat grapefruit, will that cancel the medication he took out?

It can seriously increase the level of certain meds in your body, leading to toxic reactions. Unfortunately I haven't seen anything that tells a person how to regulate their grapefruit-medication ratios. Maybe some grapefruit several times a year is okay, but you should at least alert your doctor that you plan to dabble with grapefruit if your prescriptions tell you not to consume it.

Hey Andriesa, please consult your doctor regarding the same.

I used to have kidney stones....especially when I eat a handful of cashew nuts. Immediately if I eat a grape fruit for couple of days, this pains go away....and no stone at all.....

Thank you for sharing that it is very valuable to me. I am 52 and have had two separate occasions when I had kidney stones. One was 2 weeks after a tripe by pass. As you can imagine, I was in agony. I couldn't do anything about it because they would not give me anestesia to take it out because it was so close to surgery they thought there would be a high chance of a heart attact so I had to live with the pain. It kept coming back for a couple of days for three months in a row. One doctor recommended getting a vibrating massage hand held and put it right where the stone was. He had a patient that did that and it worked. It didn't work on me, but, still thought it was a good idea. If they come back, I will surely try grapefruit juice.

Red grapefruit juice has done more for me than pharmaceutical medicines. It has relieve constipation. It has lowered blood pressure and ,yes, it has helped me to lose weight. I drink a lot of it!, it realty does suppress appetite. LOVE IT!

I use to not be able to eat grapefruits because I was on lipitor. But I found out that the whole cholesterol thing is bogus. I haven't had lipitor in 4 or 5 years now & I have been enjoying as many grapefruits as I want.

well done mate for seeing through the statin scam...unfortunately 4 of my relatives and friends have had strokes being on statins...its a ticking timebomb
