Guava is a sweet and delicious fruit cultivated in tropical climates. This seasonal fruit, scientifically known as Psidium guajava, is round or pear-shaped and is light green, yellow or maroon in color when it ripens. It has a white or maroon flesh, depending on its type, and has small hard seeds enveloped in its soft, sweet pulp. The common types of guava include apple guava, yellow-fruited cherry guava, strawberry guava, and red apple guava. It is mostly eaten raw (ripe or semi-ripe) or consumed in the form of juice, jams, and jellies.
One of the most 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, breast, and oral cancers. Guava leaf oil acts as an antiproliferative and has actually proven to be more effective than some leading modern medicines in reducing cancer cell growth. Guavas are also rich in lycopene, a powerful antioxidant that can reduce prostate cancer risk. The same antioxidant has also shown its efficacy in inhibiting the growth of breast cancer cells, though more tests are to be done to support this finding.
The naturally high content of vitamin C in guavas, which is four times higher than the content found in oranges (the traditional vitamin C powerhouse), helps boost the immune system. 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 diseases. Therefore, adding guava to your diet helps you stay healthy.
