Brazilian guavas may be small in size (they are usually no larger than golf balls) but they are big in health benefits. Just like regular guavas, these tropical treats are phenomenal sources of vitamin C. Indeed, their addition to your diet on a regular basis can make your body less vulnerable to disease-causing microbes. Commonly, Brazilian guavas are consumed as they are, their fleshy pulp with very hard tiny seeds often scooped out with a spoon. However, they are also used for baking and turned into jams and jellies. In Brazil, they are made into a paste called “goiabada” which is exported to neighboring countries.

Plant Description

Brazilian guava is a relatively slow-growing, evergreen erect shrub or small tree that grows about 1.5–6 m high with smooth, greyish bark, hairy young shoots, and cylindrical branchlets. The plant is found growing in disturbed areas, such as old pastures, abandoned agricultural areas along roadsides, wet to dry thickets, open forest, often in oak or pine forest, frequently on rocky open hillsides or plains. The plant prefers a wide range of soil types but does best on well-drained, moist, fertile loamy soils up to medium elevations. It tolerates poor soils such as light-textured sandy soils but abhors water-logged and saline soils.

Leaves

The evergreen, greyish leaves, 3.5-14 cm long and 2.5-8 cm wide, are stiff, oblong, elliptic, ovate (egg-shaped with the broad end at base) or obovate (egg-shaped leaf with the narrower end at the base), sometimes finely toothed; scantily hairy on the upper side but coated beneath with pale or rusty hairs and distinctly dotted with glands.

Flower

Flowers are white, regular, and bisexual, borne singly or in clusters of three in the axils of leaf on 1–2.5 cm long terete pedicels. The calyx is splitting into irregular, pubescent, pale green lobes, corolla with five white spreading concave obovate lobes, stamens numerous 150- with bilocular anthers, ellipsoid to globose, three to five locular with numerous ovules and style subulate.

Fruit

Fertile flowers are followed by round or pear-shaped fruit 1.5– 2.5 cm wide, with persistent calyx. The fruit is initially green turning to yellow when mature with pale-yellowish-white flesh and numerous small, hard, kidney-shaped, flattened seeds 5–8 mm diameter. The fruit has an acid, resinous, slightly strawberry-like flavor.

Health benefits of Brazilian Guava

It’s because the said mineral has vaso-dilating properties. It can cause the blood vessels to widen. As a result, blood can flow through them without any trouble. Keeping your blood pressure normal, experts say, can help in lowering your risk of ending up with the cardiovascular disease.

Another vitamin that you can obtain from Brazilian guavas is vitamin A. Just like vitamin C, it’s actually a powerful type of antioxidant. However, vitamin A is more associated with the maintenance of healthy eyes.

5. Lovelier Skin

Vitamin C found in abundance in Brazilian guavas is also important for making your skin look beautiful and youthful.

As a result, it becomes less susceptible to wrinkling as the years pass by.
