A study conducted in a test tube found that guava leaf extract could have a positive effect on blood sugar levels. It is believed that the compounds in guava leaves may interfere with sugar absorption in the blood, which could be beneficial for people who need to control their glucose. Additionally, research suggests that guava leaf tea may reduce blood sugar levels after meals, maintaining this effect for a period of two hours.
Despite the potential benefits, it is important to consume guavas in moderation, as no significant adverse effects have been identified in their consumption. Specialists suggest avoiding excessive consumption of this fruit to prevent any negative reactions, especially in people taking diabetes medications, as it could interact with them.
On the other hand, guava and guava leaf tea have been shown to have benefits for stomach and heart health. Guava is rich in fiber, promoting a healthy digestive system and helping to prevent constipation. Studies have found that guava leaf infusion can be effective in reducing the intensity and duration of diarrhea.
Furthermore, guava has been found to have properties that could benefit heart health. One study revealed that guava leaf extract had an antihypertensive effect on rodent tissues, suggesting that this ingredient could help lower blood pressure, a risk factor for heart disease.
Although there has been debate about the supposed benefits of consuming guavas on an empty stomach, there is no scientific evidence supporting this practice. The idea that eating fruit on an empty stomach provides additional health benefits is considered a myth. The nutrients in fruit are absorbed the same way regardless of whether consumed on a full or empty stomach.
In summary, consuming guavas in moderate amounts can be a healthy option, as it is a fruit rich in nutrients such as vitamin C, potassium, magnesium, and fiber. Although there are no specific benefits to consuming it on an empty stomach, including guavas in the daily diet can contribute to promoting a healthy lifestyle and strengthening the immune system.
