Side effects and other concerns

Allergic reactions

Allergies to guava rarely occur, but they can occur in people who are sensitive to the fruit or have a history of allergies.

The most common symptoms of a guava allergy include itching, swelling, and redness in the mouth and throat after eating the fruit. Some people may also experience hives or rashes on their skin, difficulty breathing, and gastrointestinal symptoms such as nausea, vomiting, and diarrhoea.

In rare cases, a severe allergic reaction called anaphylaxis may occur, which can be life-threatening. Symptoms of anaphylaxis include difficulty breathing, rapid heartbeat, low blood pressure, and loss of consciousness. If you do experience any of these symptoms after eating guava, you should seek medical help immediately.

It is also important to note that some people may experience cross-reactivity with other fruits, such as kiwi or papaya, if they are allergic to guava. This means that if you are allergic to guava, you may also be allergic to other fruits in the same family.

Interference with certain medications

While it is a good source of dietary fibre, which can help regulate blood sugar levels, it can also lower blood sugar levels, which can be problematic for people taking medications such as insulin or oral hypoglycemic agents to manage diabetes. If you are taking these medications, it is important to monitor your blood sugar levels closely and consult with your healthcare provider before adding guava to your diet.

In addition, guava can also interact with medications used to manage blood pressure, such as ACE inhibitors and beta-blockers. Guava contains high levels of potassium, which can cause potassium levels in the blood to rise. This can be dangerous for people taking medications that increase potassium levels, as it can lead to hyperkalemia (high levels of potassium in the blood). If you are taking medications for high blood pressure, it is important to monitor your potassium levels closely and consult with your healthcare provider before consuming guava.

Risks associated with consuming unripe guava

While ripe guava is safe and healthy to eat, consuming unripe guava can pose several risks and health concerns.

One of the main risks associated with consuming unripe guava is the presence of high levels of tannins. Tannins are compounds found in certain plants and fruits that can cause digestive problems such as nausea, vomiting, and diarrhoea. Unripe guava has high levels of tannins, which can be difficult for the body to digest and lead to gastrointestinal discomfort.

Another risk is its high concentration of latex. Guava latex is a sticky, milky substance that is released from the fruit when it is cut or bitten. While small amounts of latex are generally considered safe, consuming large quantities can cause allergic reactions and other health concerns. Symptoms of a latex allergy can range from mild itching and swelling to more severe reactions such as difficulty breathing or anaphylaxis.

In addition, unripe guava contains a high level of pectin, a soluble fibre that can slow down digestion and cause constipation. This is particularly problematic for people who are already prone to constipation or have digestive issues.

To minimise the risks associated with consuming unripe guava, it is important to only eat ripe guavas. Ripe guavas are soft and have a sweet, aromatic smell. Unripe guava, on the other hand, is hard and has a sour taste. 

Myths and misconceptions about guava

There are several myths and misconceptions associated with eating guava, and some of the common myths include:

Guava causes colds and coughs

This is a common myth, especially in some cultures. However, this claim has not been scientifically proven. In fact, guava is rich in vitamin C, which can boost the immune system and help prevent colds and coughs.

Guava seeds are harmful

Some people believe that the seeds are harmful and can cause digestive problems if consumed. However, this is not true. Guava seeds are edible and are a good source of dietary fibre. They can also help improve digestion and prevent constipation.

Guava causes weight gain

Another common myth is that guava can cause weight gain. However, guava is a low-calorie fruit that is rich in fibre, which can help promote feelings of fullness and prevent overeating. Including guava in a balanced diet can help with weight loss.

Guava is not safe during pregnancy

Some people believe that guava is not safe for pregnant women to consume. However, guava is a safe and nutritious fruit that can provide several health benefits during pregnancy. It is rich in folate, which is important for foetal development, and can help prevent anaemia in pregnant women.


In conclusion, guava fruit is a delicious and nutritious tropical fruit that is packed with health benefits. From boosting immunity to promoting healthy skin and hair, guava is a versatile fruit that can be enjoyed in a variety of ways. Whether you eat it raw, blend it into a smoothie, or use it in a recipe, guava is a great addition to any healthy diet.
