The 1 Food You MUST Avoid If You Have Kidney Disease
As a renal dietitian, I’m a big fan of allowing as many foods as possible in each of my client’s diets.
I never want to tell them to not eat something, especially since food is such a big part of our lives and enjoyment. Almost all foods can be included, no matter the health conditions.
But this is a hard rule for me.
Averrhola carambola, commonly known as star fruit, is a MUST to avoid if you have any sort of kidney disease or damage.
Star fruit contains a neurotoxin called caramboxin that can be filtered by fully-functioning kidneys, but can cause further kidney damage and other health issues if you have any kidney damage. If it cannot be filtered by the kidneys, the toxin collects in the blood stream and results in neurological issues.
Symptoms may include:
DEATH in serious cases
While star fruit is not a common part of the American diet, it is more prevalent in the Asian, Filipino, and other tropical diets. Consuming the fruit whole or as a juice is not recommended at all as it cannot be safely processed and eliminated for those with kidney disease or damage.
Some cases have even shown those with fully functioning kidneys develop acute kidney damage/failure after drinking or eating star fruit. If you have a higher risk of kidney disease, it may be in your best interest to limit or avoid star fruit.
What puts you at higher risk of kidney disease?
Over age of 65
Family history of kidney disease, diabetes, or hypertension
