Guava is one of the most nutrient-dense tropical fruits, widely known for its exceptional vitamin C, fiber, and antioxidant content.

Often called a “Superfruit” by food experts, it not only supports immunity but also aids your digestion, heart health, and weight management.

With its sweet aroma and versatile culinary uses, guava is often enjoyed fresh, in juice/smoothies, or even as a base for jams.

Let’s explore what makes guava so special, its nutrition facts, health benefits, and the best ways to enjoy it.

What is Guava?

Guava (Psidium guajava)^[1] is a tropical fruit native to Central and South America, but it is now widely grown in Asia, Africa, and the Caribbean.

Belonging to the myrtle family, it comes in several varieties. Some have green or yellow skin with pink, red, or white flesh.

In India, it is popularly known as Amrud and Guyabano in the Philippines (though this often refers to soursop).

Guava also holds cultural importance in many countries.

For instance, in Mexico, guava is a key ingredient in ponche navideño^[2], a traditional Christmas punch.

What Does Guava Taste Like?

A ripe guava has a unique balance of sweetness and tartness, often described as a cross between a strawberry and a pear.

The texture is soft and juicy, with tiny edible seeds inside it. Some varieties of guava will have a mild and sweet taste, while others can have a sharp tang.

The aroma is often very strong and fruity in the open air, making guava very easy to recognize even before tasting.
