Why shouldn’t kidney patients consume star fruit?

Browse By

Star fruit is a fruit that is both beneficial and can cause toxicity to the body. This is because star fruit is high in potassium, which affects kidney function. Oxalate binds with calcium and crystallizes in the kidneys, resulting in kidney failure. Oxalic acid makes symptoms of kidney disease worse and is a risk factor for urinary stones. This is why kidney disease patients should not consume star fruit.

Starfruit toxicity

Star fruit toxicity does not only affect the kidneys. Consuming star fruit in large quantities can affect various systems in the body.

1. Kidney toxicity

  • Patients will experience acute kidney failure several hours after eating star fruit, including high blood pressure, pulmonary edema, and little urine output because waste products that are stuck in the kidneys cannot be excreted. They may need to undergo dialysis, which takes 3-4 weeks for the kidneys to function normally.

2. Neurotoxicity

  • It often occurs in patients who eat a lot of star fruit. They will experience cerebral edema and meningitis due to the formation of calcitum oxalate crystals that stick to the blood vessel walls in the meninges. However, neurotoxicity caused by eating star fruit is rare.

3. Toxicity to the digestive system

  • Star fruit contains oxalic acid, which is acidic. Eating star fruit in large quantities can cause irritation in the digestive system. In severe cases, symptoms include nausea, vomiting, stomach cramps, and reduced food and water intake.

Factors influencing disease caused by star fruit consumption

  • Star fruit varieties: Star fruits with sour taste contain more oxalic acid than star fruits with sweet taste, so consumers of star fruits with sour taste are at higher risk of disease.
  •  Quantity: Eating star fruit in large quantities will result in higher levels of oxalate.
  •  How to consume If you eat star fruit that has been processed, such as pickled, candied or dried, the oxalate content will be reduced. The risk of various diseases will be less than consuming fresh star fruit.
  •  Absorption: Eating star fruit on an empty stomach, oxalate is freely absorbed and excreted by the kidneys. However, if combined with calcium, it crystallizes as calcium oxalate in the kidney tissue, which can result in kidney failure.
  •  Dehydration: If star fruit juice is consumed after exercise or after a lot of sweating, calcium oxalate crystals can easily form in the kidney tissue, leading to kidney failure.
