Although it brings many benefits to healthy people, kiwi can pose certain risks for people with impaired kidney function.
One of the important reasons why people with kidney failure should limit kiwi is due to the high potassium content. Potassium is a mineral necessary for the body's activities, but when the kidneys function poorly, the ability to excrete potassium is reduced. This leads to hyperkalemia - a dangerous complication that can cause heart rhythm disorders, even life-threatening. Kiwi, along with some fruits such as bananas or oranges, belongs to the group of potassium-rich foods, so it is not suitable for regular consumption in people with kidney failure.
Besides, kiwi also contains a certain amount of phosphorus. Under normal conditions, the kidneys help regulate phosphorus levels in the blood. However, when kidney function declines, phosphorus can accumulate in the body, adversely affecting bones and the cardiovascular system. Eating a lot of kiwi, although not a high source of phosphorus, but if combined with other foods rich in this mineral, can still contribute to making the situation more serious.
Kiwi is mildly acidic and rich in fiber. For people with kidney failure, especially in severe stages, the digestive system may function worse. Consuming too much fiber or acidic foods can cause bloating, indigestion or stomach irritation. This makes the body more tired, affecting the quality of life.
However, this does not mean that people with kidney failure must completely eliminate kiwi from their diet. In some mild cases and with the guidance of a doctor or nutritionist, patients can still eat in small amounts, strictly control their diet and monitor biochemical indicators.
Although kiwi is a nutritious food, people with kidney failure need to limit consumption due to the risk of increased potassium, phosphorus accumulation and digestive effects. Building a suitable diet, personalizing it according to each stage of the disease is an important factor to protect kidney health and improve quality of life.
