- The fruit is a very rich source of soluble dietary fiber (5.4 g per 100 g of fruit, about 14% of DRA), which makes it a good bulk laxative. The fiber content helps protect the colon mucosa by decreasing exposure time to toxins as well as binding to cancer-causing chemicals in the colon.
- Guava-fruit is an excellent source of antioxidant vitamin-C. 100 g fresh fruit provides 228 mg of this vitamin, more than three times the required DRI (daily-recommended intake). Flesh just underneath its thick outer rind composes exceptionally higher levels of vitamin-C than its inner creamy pulp.
- Scientific studies suggest that regular consumption of fruits rich in vitamin-C helps the human body develop resistance against infectious agents and scavenge cancer causing harmful free radicals from the body. Further, it is essential for collagen synthesis within the body. Collagen is one of the chief structural protein in the human body necessary for maintaining the integrity of blood vessels, skin, organs, and bones.
- The fruit is a very good source of Vitamin-A, and flavonoids like beta-carotene, lycopene, lutein and cryptoxanthin.

- 100 g of pink guava fruit provides 5204 µg of lycopene, nearly twice the amount than in tomatoes. (100 g tomato contains 2573 µg of lycopene). Studies suggest that lycopene in pink guavas prevents skin damage from UV rays and offer protection from prostate cancer.
- Fresh fruit is a very rich source of potassium. It contains more potassium than other fruits like banana weight per weight. Potassium is an important component of cell and body fluids that helps controlling heart rate and blood pressure.
