Guava Kumagai’s Health Benefits

Originally from the tropical areas of America, guava has spread around the world and is in the taste of most people, who import this fruit for fresh consumption or in juices, cakes, sweets and other ways, in addition to the famous guava. And in each place, new varieties are developed that seek to improve the fruit in order to produce it more and sell it for better prices, among other reasons. And in Brazil this is no different. An example of this is the guava Kumagai , a type of the fruit that was created in the district of Pedra Branca, region of Valinhos, near Campinas, in the interior of São Paulo.

The fruit’s name refers to the last name of the Japanese family that developed this variety in the 1970s. After the death of the family’s patriarch, the children got together, divided the land evenly and decided to continue the production of Kumagai guava. In a short time, the fruit began to be exported to other countries, making it a real success.

The Kumagai guava has a smooth skin and a lighter green color than the others, corresponding to a yellowish-green when ripe. With firm consistency, its pulp is completely white, with a lot of filling and few seeds. Slightly acidic, it is a very tasty fruit with a strong taste. With a rounded shape, the fruit is larger than the conventional ones, being able to exceed 300 grams and reach approximately half a kilo. Thinking about commercialization, it is worth saying that the kumagai guava is very resistant to transport.


The Kumagai guava has properties that provide great well-being to those who consume them regularly. Firstly, this fruit is a great partner for those who want to lose weight, as the fibers present in it help the body to feel satisfied for longer, which will help to reduce food intake and, consequently, reduce the pounds in the balance. Fiber is also great for speeding up metabolism, another good point for weight loss. At the same time, guava provides energy and provides proteins and minerals that are essential for those who are exercising.

Another benefit of Kumagai guava provided from its fibers is the possibility that they contribute to the intestine, making its functioning more regulated, while cleaning the intestinal tract. Vitamin C and potassium, which are abundantly present in white guava, contribute to the health of the digestive system.

Antioxidants are great properties of the guava Kumagai, as they are strong allies in fighting free radicals that are responsible for the aging of the body and also usually cause the appearance of various types of cancer. Such antioxidants – in addition to vitamins A, C and manganese present in the fruit – also act against skin aging, preventing the appearance of new wrinkles and expression lines, making your complexion younger and healthier.

White guava is well known for having in its composition a substance called folate. It works in the body to maintain fertility in humans. Another positive point is the vitamin A and retinol present in guava, both of which help to keep your eyesight good for longer.

The Kumagai guava has the benefits of relaxing the nerves, calming the nervous system. This is due to the abundant presence of magnesium in the fruit. This substance contributes to the relaxation of nerves and muscles. In other words, consuming a white guava after a heavy and tiring day at work is a great way to calm the head and give an extra dose of energy, giving a new spirit to the person.

Rich in potassium, kumagai guava helps control blood pressure, which will positively impact the functioning of the heart, warding off possible heart disease. To give you an idea, a guava has about the same amount of potassium as a banana. Guava is also good for people with diabetes, as it helps to control the level of sugar in the blood, preventing the occurrence of spikes in blood glucose. By the way, drinking white guava juice is a good way to boost the effects against diabetes.


If you want to plant this variety of guava at home, be aware that you must first buy Kumagai guava seedling. As this variety is original from the region of Campinas (SP), it may be necessary to know how to buy Kumagai guava seedlings directly from producers. Another option is to search the internet for companies specialized in seedlings that may have them or know how to acquire them. It is important to remember that the use of seedlings is recommended, as they develop faster than cultivating them with seeds from the fruit itself.

With the Kumagai guava seedlings in hand, you should prepare the soil, making a deep hole in the yard, so that the seedling can grow and spread under the ground. If you prefer, spread limestone through the soil, which is positive for growing it. Then balance the soil pH, which should be between 5.5 and 6.8. If you live in a place that rains a lot, this process can be made easier. The terrain must necessarily be flat, at most with a slight slope. Remember that the land cannot be soaked, otherwise the guava tree will not develop satisfactorily.

If you intend to place more than one seedling, take into account the need to establish a space between them so that each one develops naturally, without any hassles. Consider at least three meters apart.

Guava production occurs all year round, but from January to April there is an even greater fruit production. Therefore, it is recommended that the guava tree be harvested three times a week. But beware: only remove guavas that are well developed. At the same time, make the prunings for the formation of new fruits, as well as guiding the branches and cleaning the guava tree. These actions will reduce the propensity for pests and diseases.
