Guavas are often considered super fruits, being rich in vitamins A and C, and especially high levels of pectin and dietary fiber. A single Guava contains over four times the amount of vitamin C as a single orange, and also has good levels of the dietary minerals, potassium, magnesium, and an otherwise broad, low-calorie profile of essential nutrients. Studies show that guavas are the great source of vitamin C (185 ml-190 ml/ 100 g of edible parts). Guavas contain both major classes of antioxidant pigments; carotenoids and polyphenols, giving them relatively high dietary antioxidant value among plant foods.
