Could Eating More Than 6 Bananas In A Go Kill You?

Sure you want to go bananas?

We can hear a bunch of minions protest against the very existence of this question.

Everyone loves a banana once in while – be it the fruit or a person acting like one. They are one of the world’s most popular fruits, stuffed with vitamins and minerals. On the face of it they are good for you, so why do some people think they could be fatal?Despicable-Me-Minion-Saying-What


Pilkington Picking On Bananas

One well-known figure who has spread this idea around is Karl Pilkington, the grumpy friend of comedian Ricky Gervais.

“Before when you were talking about bananas. I had that fact, about if you eat more than six, it can kill you,” he said in one of his conversations with Gervais and fellow comedian Stephen Merchant.

“It is a fact. Potassium levels are dangerously high if you have six bananas. I saw a bowl of bananas. There are six bananas there. You know why there’s only six? Seven would be dangerous.”_85501492_banana-truck-kolkata-getty


Poisonous Potassium?

So how dangerous is potassium? Essentially, it is crucial for survival and can be found “within every single cell of the body,” says Catherine Collins, a dietitian at St George’s Hospital in London.

“We use it to help generate an electrical charge which helps the cell function properly. It helps keep your heart rate steady, it helps trigger insulin release from the pancreas to help control blood sugars, and more importantly keeps blood pressure in check.”_85500702_bunch-of-seven-think-976

On the other hand, if the level of potassium in the body is too low or too high it can result in an irregular heartbeat, stomach pain, nausea and diarrhea. In fact, Potassium chloride is even one of the chemicals used in lethal injections in the US, as extremely high doses can cause cardiac arrest. Whoa!


Talking Healthy Tho

For a healthy person, “it would be impossible to overdose on bananas,” says Collins. “You would probably need around 400 bananas a day to build up the kind of potassium levels that would cause your heart to stop beating. Bananas are not dangerous – and in fact they are, and always have been, very good for you.”

Adults should consume about 3,500mg of potassium per day, according to the UK’s National Health Service. The average banana, weighing 125g, contains 450mg of potassium, meaning a healthy person can consume at least seven-and-half bananas before reaching the recommended level.BananaPEels


But But!

There are some people who should steer clear of foods that are high in potassium though – those with kidney disease.

“These patients have a very low kidney function which can potentially see a build-up of harmful potassium levels in their blood stream because they can’t get rid of the mineral when they pass urine,” Collins says. “So in theory it is possible for someone with kidney disease to die of a high blood potassium level if they decided to consume lots of different food types rich in the mineral.”fruits-grocery-bananas-market


Toxic Bananas

Another thing that could cause some to worry about bananas is radiation.

Like many foods, bananas naturally contain some radioactive isotopes – enough for the US-based think tank, Nuclear Threat Initiative, to warn that they can trigger sensors used at US ports to detect smuggled nuclear material. Wait, what?

But relax. You’re not consuming toxic ish. A typical banana contains 0.1 micro Sieverts of radiation. To give you a better perspective, a typical CT scan in a hospital exposes humans to between 10 and 15 milli Sieverts – about 100,000 times more.bananas

“The levels of radioactivity are negligible,” says Collins. “Bananas are not as radioactive as Brazil nuts and they are safe to eat in moderation.”

Brazil nuts are radioactive?!
