Guava is a fruit that is highly appreciated for its rich content of vitamin C, fiber and antioxidants. Many people choose guava juice as a nutritious daily drink.
In terms of nutrition, guava juice provides vitamin C, potassium, folate and many plant compounds with biological activity such as carotenoids and polyphenols. These antioxidants help reduce oxidative stress - one of the factors that can contribute to cell damage in the body, including kidney cells.
A diet rich in fruits and vegetables can support cardiovascular health and metabolism, thereby indirectly helping to protect kidney function.
For people with healthy kidneys, drinking guava juice in a reasonable amount can be part of a balanced diet. The water content in this drink helps support the process of excreting waste through the urinary tract.
Vitamin C in guava also helps strengthen the immune system and support the body against harmful agents from the environment.
However, it should be noted that when juiced, a significant part of the fiber in guava is removed. Fiber plays an important role in controlling blood sugar and supporting gut health. Therefore, eating guava whole often brings more benefits than just drinking juice. If making juice, you should keep the flesh or blend it to maximize the amount of natural fiber.
A point that needs special attention is the potassium content in guava. For people with progressive chronic kidney disease, the ability to excrete potassium may be reduced. At that time, consuming too many potassium-rich foods, including guava juice, can increase blood potassium, affecting cardiovascular health and overall health.
People who are being treated for kidney disease should consult a doctor or nutritionist before regular use.
In particular, do not add too much sugar to guava juice. Excess sugar can increase the risk of overweight, obesity and diabetes - the top risk factors leading to long-term kidney damage.
Guava juice can bring benefits to kidney health in healthy people thanks to containing many vitamins and antioxidants. However, it should be used in moderation, limiting added sugar and prioritizing eating whole guava to maximize nutritional value. For people with kidney disease, use needs to be individualized according to the doctor's instructions.
