I went to the store last night with my grandma as she was nice enough to buy me groceries. My cart was half full of bananas, when she saw this, she started commenting to me about how "too many bananas" and there is a possibility I could overdose on potassium. She is a registered nurse and I know conditioned from medical training. I don't buy into this one bit and just shrugged it off, but I wish I had a knowledgable response for when she makes these comments. Can you help me out? And while I'm here I guess I will also throw out there, "is it possible to overdose on potassium from too many bananas?"
You can only overdoze on potassium if you have kidney failure, overwise kidney should be able to remove all access potassium from the body and maintain the homeostasis. Most ppl on SAD diet do not get enough potassium and take way too much salt/sodium?
I think potassium overdose claim is in the same league as Where do you get your protein from :D
Potassium overdose can happen through synthetic chemicals sure.
It doesn't work this way with fruit though because of all the fiber, nutrients and water content slowly being released instead of it all instantly being released.
If you take a shot of synthetic potassium you can die depending on the dose.
If you take a shot of natural extracted potassium, you can die, but it would need to be a MUCH higher dose than synthetic.
Just get all of your potassium from fruit, and you will be okay.
Tell them to show you somebody who got a potassium overdose from bananas. They can't.
It is possible to overdose tho if you eat about 250 bananas in one sitting..:)
give her a copy of the GERSON therapy against cancer and to cure cancer.
The first thing he did was put his patients on a diet super high in potassium and super low in sodium.
There's a thread in here on potassium somewhere if you want to learn more but yes,
basically impossible to overload unless you have kidney problems, that's what i've
been reading over and over again too. :) Plus, our need for potassium is a lot higher than they tell us
and even just 5 bananas barely cover the minimum amount described by the RDA...
Potassium is water soluble so any excess you consume from fruits and vegetables will be excreted when you pee. It is essential for nerve and muscle activity so if I were you I'd turn the tables on them and ask them where they get their potassium from as you don't want them to suffer from hypokalaemia (Low potassium). (;
There are people on this forum who have been eating this way for 10 years and more. If there was a real possibility of getting potassium overload don't you think it would have happened by now?
One would have to eat about 440 bananas to come close to overload. Most potassium is excreted in the urine.
I found this on a website:
"The normal level of potassium in the bloodstream is in the range of 3.5-5.0 mM, while levels of 6.3-8.0 mM (severe hyperkalemia) result in cardiac arrhythmias or even death due to cardiac arrest. Potassium is potentially quite toxic, however toxicity or death due to potassium poisoning is usually prevented because of the vomiting reflex. The consumption of food results in mild increases in the concentration of potassium in the bloodstream, but levels of potassium do not become toxic because of the uptake of potassium by various cells of the body, as well as by the action of the kidneys transferring the potassium ions from the blood to the urine. The body's regulatory mechanisms can easily be overwhelmed, however, when potassium chloride is injected intravenously, as high doses of injected potassium can easily result in death."
