I would recommend recording your normal food intake very carefully for a two or three days and carefully entering this into a nutrient tracking software program. Then you would have an idea of how much potassium you are actually consuming.
It seems unlikely that you are consuming too much potassium unless you are really eating a great deal of potassium rich plants.
A potassium level of between 5 and 6 is classed as mild and is unlikely to have any symptoms.
There are a variety of medical issues that can lead to high potassium levels. Any of these are something to talk to a doctor about. Your kidneys usually maintain the level of potassium in the blood over a wide range of intakes.
It is less likely to be directly caused by potassium in your food unless you are also taking potassium supplements.
You can try reducing the amount of potassium in your diet but you can only really do this if you know how much you are currently eating.
everything good has potassium in it!
This may be a clue. I'm not concerned that potassium intake is too high. I'm certainly not going to try and artificially counteract it. Maybe someone else has more info, but I've not heard that this is an area to be worried about. At best there may be some issues with salt balance.
How on earth have you got so much potassium??!! According to FitDay, I rarely get 30% of my RDA - and I eat really well. Kidneys, liver, lots of veg, the occasional banana - but so rarely over 30%.
Or is Fit Day just utterly inaccurate?
Seeing as how increasing your potassium to sodium ratio is one of the ways of lowering your blood pressure, the ideal ratio of K:Na is in the range of 2:1, and the average ratio in the US is 1:2, I don't see this as much of an issue, even if you are VLC and your body is potassium sparing.
Yes, high serum potassium is a real concern. My guess is that you don't need to worry about it as long as you aren't supplementing with it as we've been eating a high potassium diet for a long time. That's not the case with sodium, which is why our kidneys have to actively pump it out.
