Guava must be eaten at any time except on an empty stomach. This goes for bananas too. This is because, if your body needs to reap the benefits of these fruits, there must be some food in your stomach for it to digest and mix along with. Also, keep in mind that this must be consumed 30 minutes after you finish eating.
Guava fruit, as well as its leaves, have medicinal properties that can heal certain health problems. However, make sure that you do not consume it in excess.
Just like the old-fashioned saying, ”An apple a day keeps the doctor away”, similarly, guavas have better healing properties than an apple. But, if you’re allergic to guavas, then you need to consult a doctor and ask him/her for a solution.
