Guava (Psidium guajava L.) fruit is generally ovoid or pear shaped
native to Mexico and it is available throughout South America,
Europe, Africa and Asia. It also grows in all subtropical areas [1].
Guava is often marketed as ‘‘super-fruits’’ which has a considerable
nutritional importance in terms of vitamins A and C with
seeds that are rich in omega-3, omega-6 poly-unsaturated fatty
acids and especially dietary fiber, riboflavin, as well as in proteins,
and mineral salts. The vitamin C in guava makes absorption of vitamin
E much more effective in reducing the oxidation of the LDL
cholesterol and increasing the (good) HDL cholesterol. The fibers
in guavas promote digestion and ease bowel movements. The high
content of vitamin A in guava plays an important role in maintaining
the quality and health of eye-sight, skin, teeth, bones and the
mucus membranes [2]. The anti-oxidant virtue in guavas [3] is
believed to help reduce the risk of cancers of the stomach, esophagus,
larynx, oral cavity and pancreas.
