The person that kidney function is not complete, had better not eat carambola

Investigation found that many people with renal dysfunction, because of the consumption of carambola poisoning symptoms, life threatening. Although most of these unfortunate people survived the rescue, but people who love to eat carambola can not help but have the heart of the question: is carambola poisonous? Can I have a good time with carambola?


Is carambola poisonous?

Carambola is abundant in Southeast Asian countries and China’s Guangdong, Guangxi, Hainan Island and other places. For most people, carambola is a kind of delicious tropical fruit, deeply loved by men and women, young and old.

But for people with kidney disease, carambola can be deadly.

People with chronic kidney disease who eat carambola can have toxic symptoms such as hiccups, vomiting, confusion, disturbance of consciousness, shock and epilepsy. In severe cases, they can even lead to death.

Because fewer people affected by carambola, kidney disease patients eat carambola before these obvious symptoms of poisoning, so, before the “carambola toxic” problem has not caused concern. It wasn’t until 1998, when a doctor in Brazil observed that six dialysis patients had symptoms of poisoning from eating carambola, which could lead to poisoning, that attention was paid to it.

Since then, every year there are a few to more than a dozen cases of kidney disease patients because of carambola vomiting, epilepsy or poisoning cases of delirium. From boys in their twenties to aunts and aunts in their sixties and seventies, some people have been poisoned by carambola.

Why do delicious fruits become “lethal poisons”?

Carambola contains a neurotoxin that affects the central nervous system of the human body.

A study from Brazil showed that the culprit causing poisoning was a previously unknown compound named caramboxin. The researchers extracted the substance from carambola and analyzed its structure and found that its structure is similar to phenylalanine, one of the essential amino acids. The brain of the experimental animal was then injected with the toxin caramboxin, and the experimental animals were found to have the same epileptic symptoms as when the carambola extract was injected. Further research has found that this toxin affects the glutamate neurotransmitter receptors in the brain, causing abnormal brain excitation, which can lead to symptoms of poisoning.

In people with normal kidney function, if a small amount of carambola is eaten, the toxin will pass through the kidney to filter urine and finally excreted.

However, in patients with impaired renal function, this neurotoxin is left in the body due to the filtration of the kidneys, resulting in various symptoms of poisoning. Once these patients have poisoned reaction with carambola, general peritoneal dialysis has no effect on carambola poisoning. Most patients need daily intensive hemodialysis to return to normal, but there may still be sequelae.

Can you still eat carambola?

Patients with renal insufficiency must fasten fresh carambola and freshly squeezed carambola juice to prevent symptoms of poisoning.

In addition, because there are cases in the country where people with no history of kidney disease have eaten too many cases of acute renal failure caused by carambola, even healthy people, especially the elderly, who can excrete toxins normally should be as few as possible. Eat carambola, one or two a day, just fine.

Perhaps, in the future, the neurotoxins in the carambola juice can be separated by the separation technique, so that everyone can enjoy the sweet and sour taste brought by the carambola.
