Guava is rich in calcium, iron, magnesium, phosphorus, zinc and potassium.
A large numbers of minerals are essential for human body and have a wide variety of roles in the human body. Bones and teeth are mainly made up of calcium, magnesium and phosphorus.
Minerals like zinc are activators of certain enzymes.
Calcium, associated worth cell wall structure, is important in fruit softening. Guava is a slightly acid forming food, with a calcium (23mg/100 g) – phosphorus (42 mg/100 g) ration of 0.55 and is in this regard similar like soya milk, which is ration 0.51. Calcium also plays a vital role in blood clot formation, muscle contraction, cell membrane permeability, signal transduction and activation of enzymes.
Guava are the major dietary source of potassium, the most abundant mineral in fruits. Many studies show that people who eat potassium-rich fruits have lower rates of heart related disease and high blood pressure. It helps maintain normal fluid balance in the body.
While for magnesium, it is essential for strengthening bones, making new cells, activating B vitamins, relaxing nerves and muscles, clotting blood, and building DNA and protein.
Guava is very good source of iron. Iron is an important constituent of blood. It is a component of heme pigments and of some enzymes.
Zinc is the second most important of the essential trace elements for humans, it is a constituent of some enzymes, such as carbonic anhydrase.
