Health Benefits of Guava

in Fruit

The health benefits of guava include the treatment of diarrhea, dysentery, constipation, cough, cold, skin care, high blood pressure, weight loss and scurvy.

Many of you may have tasted this mouth-watering treat, or have at least seen or heard about it. Guava is very common in Asian countries, but is increasingly available in the western world, particularly as more of its health benefits are revealed. It is a somewhat round or pear-shaped seasonal fruit, and is light green, yellow, or maroon in color on the outside when it is ripe. Guava also has white or maroon flesh and lots of small hard seeds enveloped in very soft, sweet pulp. It is eaten raw (ripe or semi-ripe) or in the form of jams and jellies.

This popular fruit is a powerhouse of nutrients. If the traditional adage says that “An apple a day keeps the doctor away” in Europe and Americas, the phrase is probably changed to “A few guavas in the season keeps the doctor away for the whole year” in the Indian Subcontinent and places where guavas typically grow. Its scientific name is Psidium Guajava.

What makes guava special is that protecting the fruit does not require excessive use of chemical pesticides as in the case of grapes, apple, and other so-called “exotic” fruits. It is one of the least chemically treated and sprayed fruits.

Health Benefits of Guava

Some of the surprising and brilliant health benefits are listed below.

Weight loss: Guava is very helpful for those who want to lose weight without compromising their intake of proteins, vitamins and fiber. Guava is very high in roughage and rich in vitamins, proteins and minerals, but it has no cholesterol and a low number of digestible carbohydrates. It is a is very filling snack and satisfies the appetite very easily. Guava, especially raw guava, also has far less sugar as compared to apples, oranges, grapes, and other fruit. Adding a medium-sized guava to your lunch and you will not feel hungry again until the evening. Ironically, it can also help with weight gain in lean, thin people. This is probably due to its wealth of nutrients, which keep the metabolism regulates and helps to promote the proper absorption of nutrients.

Guava2Diabetes: In a related benefit to blood pressure mentioned above, an intake of guava can also help those patients who suffer from diabetes. The high level of dietary fiber in guava helps to regulate the absorption of sugar by the body, which decreases the chances of major spikes and drops in insulin and glucose in the body. Studies have shown that consuming guava can help prevent the appearance of type-2 diabetes.

Eyesight: Guavas are extremely good sources of vitamin-A, which is well known as a booster for vision health. It can help slow down the appearance of cataracts, macular degeneration, and general health of the eyes. It can not only prevent degradation of eyesight, but even an improvement in eyesight once it has begun to degrade.

Cancer Prevention: One of the most celebrated and important benefits of adding guava to your diet is its ability to inhibit the growth and metastasis of cancerous cells. There have been numerous studies done in recent years on guava’s effects primarily on prostate cancer, breast cancer, and oral cancers. Guava leaf oil is extremely successful as an anti-proliferative substance, and has actually been shown to be more effective than some leading modern medicines in reducing cancerous growth. Guavas are also rich in lycopene, a powerful antioxidant that has been shown to be wildly successful in reducing prostate cancer risk. That same antioxidant has also shown to inhibit the growth of breast cancer cells, although further human trials need to be done.

Finally, the naturally high levels of vitamin-C in guavas, which are four times higher than the levels found in oranges (the traditional vitamin-C powerhouse), provides the immune system a huge boost in antioxidants. Antioxidants are the major lines of defense against the proliferation of free radicals in the body, which are one of the main causes of serious conditions like cancer and heart disease. Therefore, adding guava to your diet has numerous ways in which it helps you stay health and cancer-free.

Scurvy: Guava can outdo many other fruits, including orange and other citrus fruits, in terms of its concentration of vitamin-C. A  deficiency of vitamin-C can cause scurvy, and proper intake of vitamin-C is the only known remedy for that dangerous disease. In fact, guavas contain 5X more vitamin-C than oranges, which are often heralded as the absolute best source of that beneficial vitamin.

Diarrhea & dysentery: Guava is very rich in astringents (compounds that make your gums feel tighter and fresher).  After you chew guava leaves, eat a raw guava, or use some guava-based toothpaste), your mouth feels healthier, and the astringent qualities also add substance to loose bowels and reduce symptoms of diarrhea. These astringents are alkaline in nature and have disinfectant and anti-bacterial properties, thus helping to cure dysentery by inhibiting microbial growth and removing extra mucus from the intestines. Furthermore, other nutrients in guava such as vitamin-C, Carotenoids and potassium, strengthen and tone the digestive system while simultaneously disinfecting it. Guava is also beneficial in treating gastroenteritis for the same reasons stated above.

Thyroid Health: Guavas are a good source for copper, which is an important part of regulating thyroid metabolism by helping to control hormone production and absorption. The thyroid gland is one of the most important glands in the body for regulating hormones and organ system function, so guava can help balance your health in many ways.

Constipation: Guava is one of the richest sources of dietary fiber in terms of fruit. Its seeds, if ingested whole or chewed, serve as excellent laxatives. These two properties of guava help the formation of healthy bowel movements, and aid the body in retaining water and thoroughly cleaning your intestines and excretory system. It is said that constipation alone can lead to 72 different types of ailments, so any help with constipation is beneficial. Your total health is undeniably affected by proper digestion, and more importantly, proper excretion. Frequent consumption of guava can ensure both.

Brain Health: Another of the tremendous positive benefits of guavas is the presence of B3 and B6 vitamins. B3 (also known as niacin) can increase blood flow and stimulates cognitive function. B6 is a great nutrient for brain and nerve function. Therefore, eating guava can help you increase brain function and sharpen you focus.

Cough & cold: Juice of raw and immature guavas or a decoction of guava-leaves is very helpful in relieving coughs and colds by  reducing mucus, disinfecting the respiratory tract, throat and lungs, and inhibiting microbial activity with its astringent properties. Guava has one of the highest quantities of vitamin-C and iron among fruits, and both are proven to be preventive against colds and viral infections. In some areas of India, roasted ripe guava is used as a remedy against extreme cases of cough, cold, and congestion. Ripe guava should be avoided by people who are suffering from cough and cold, as it can exacerbate the problem, and one should also avoid drinking water immedaitely after eating guava as it can lead to a sore throat.

guava_1Skin care: Guavas can improve the texture of your skin and help you to avoid skin problems more than even the highest ranked beauty creams or skin toner gels. This is chiefly due to the abundance of astringents in the fruit (more astringent is present in immature guavas) and in its leaves. Your skin can benefit from either eating the fruits (this helps tighten your muscles apart from your skin) or by rinsing your skin with a decoction of its immature fruit and leaves. It will tone up and tighten the area of loosened skin where you apply it. In addition to the astringents, guava is very rich in vitamin-A, B, C and potassium which are  good antioxidants and detoxifiers, which keep your skin glowing and free from signs of premature aging, wrinkles and other dermal disorders.

High blood pressure: Guava helps reduce cholesterol in the blood and prevents it from thickening, thereby maintaining the fluidity of blood and reducing blood pressure. Studies have shown that food lacking fiber (such as refined flour) add to blood pressure, due to its quick conversion to sugar. Guava, being very rich in fiber and hypoglycemic in nature, helps reduce blood pressure.

Other benefits:  There are so many health benefits of guava, it is hard to know where to begin. It is important to know that guava helps control diabetes and protects the prostate.  The juice of guava leaves has been known to cure toothaches, swollen gums & oral ulcers, and the juice speeds up the healing process of wounds when applied externally. Finally, it reduces the frequency of convulsions, epilepsy, and bacterial infections.

As with many alternative foods and supplements, there is little risk in eating them in natural form, but you must do your due diligence when taking it in medical forms. Be cautious when adding any new medicinal form of guava into your diet, and it is better to stick to eating guava in its natural form as a raw fruit.

    Guava leaves are excellent in treating skin rashes as well. Base on my own experienced, I have skin rashes all over my arms, tummy and thighs. I tried using hydrocortizone for couple days and hoping my rashes would go away, but it didn’t. My skin rashes got worst, so I decided to see a doctor. My doctor prescribed me some antihistamine pills and some steroidal cream. I used this for a week, but it doesn’t do anything. I went back to my doctor again and then she gave me another prescription (more doses). I used it for 2 weeks and my skun rashes starting to heal. I stop using the medicine coz I thought my skin rashes are gone. Then, a couple days after, my skin rashes are back and it become worst that it peeled my thighs skin. I rushed to the doctor again and they said they don’t know what’s going on. They told me to see a dermatologist. I said, it’s gonna be hard on my part because I am a student and don’t have health insurance yet. Then, I called my mom and told her what’s goin on and told me to try boiling a young guava leaves and apply it on affected areas. I told to myself, “okay, I’m going to give myself 2 weeks to use this and if I’m not healing, -suck it, I’m going to see a dermatologist. I boiled young guava leaves, let the temperature cool down and I applied it religiously on my skin. I would say, it is a miracle! A week and a half, my skin went back to normal again! It’s amazing how the creation of God heals us in a very mysterious ways.

  8. I’m a Diabetic patient though I’m taking my maintenance medications my blood sugar reaches to 200 – 215 two hours after eating, I’ve been eating Guava since a long time its one of my favorite fruit! But lately, I noticed that even after eating a heavy meal the level of my blood sugar was 96 or 106. I really don’t know if it’s from guava. As of now I’m still observing my blopd sugar level in relation to Guava but I’m happy for the result.

      Guava is seasonal, late spring, summer and early fall…..seeing as you posted this in January I can see why you had trouble finding it. As for where almost any grocery store should have them in season.
