Side Effects of Guava

There are no serious side effects of guava fruits and leaves for those who take it in moderate amounts. However, eating too much can lead to digestive issues like constipation. Though the chances are low, studies show that it’s also possible to develop an allergy to some of the chemicals in guava.

Apart from the fruit, the chemicals used to store it could also pose some health risks for you. These chemicals have the potential to cause different types of infections. This is why you should thoroughly wash guavas before eating them.

1. It can make you feeling frequently bloated.

Like other fruits, guavas are a classic trigger for bloating, as it is rich in a type of sugar, known as fructose. Unfortunately, our body is not well equipped to digest and absorb huge amounts of fructose. In fact, researchers believe that up to 40% of people are suffering from a condition referred to as fructose malabsorption, where this sugar is inefficiently absorbed in the small intestine. So, overconsumption of this fruit will make it just sitting in our stomach and cause bloating, which is caused by the gas produced by bacteria feasting on the fructose.

2. It can cause diarrhea or irritable bowel syndrome.

Due to fructose malabsorption, you would also experience diarrhea or messed-up digestion issues. As guavas carry seeds to make new plants, it is natural for them not to be fully digested by humans, as seeds are designed to survive transit and get deposited in new locations to grow new plants or trees.

3. It will cause you to always crave for sugar.

Overconsumption of this fruit will not only spike your blood sugar, but it will also make you unable to sustain it for very long. As you may have notice, your stomach would start growling again not long after you get a fill of this fruit. The reason for this is that it is not packed with much fat or protein that keeps us sated. While it helps us with fiber, it is not sufficient to prevent a crash in our blood sugar after eating it.

4. It is prone to bacterial contamination.

Like other fruits on display, guavas could be exposed to a plethora of bacteria, such as listeria, E. coli and salmonella, which can attach to the fruits from the wind, water and soil. While they may have a tough exterior to keep bacteria out, it can be penetrated and contaminated if the skin is broken. And for the case of the guava, you would eat it raw with the skin, so your chance of ingesting bacteria can be high.

5. It is not always available.

According to experts, many people eat sufficient amounts of fruits in their daily diets to reduce their risk of developing certain health conditions, with the help of their healthy contents. Unfortunately, fresh fruits, including guavas, are not always available in many places, and if they are, they would be expensive to buy. This is especially true for guavas, considering that they are only grown in tropical and sub-tropical regions, making them scarce in other parts of the world.

As with many other fruits, eating guava fruit in its natural form is very healthy, though it also comes with some risks. With these lists, you will be able to build a well-informed opinion whether the fruit is entirely good for you, or not.
