Potassium question

in Food and Nutrition
I just started tracking about a week ago and am doing pretty well at hitting calorie and nutrient targets. However I did notice that I never hit my target for potassium. Every day this past week it was low - not even close to the recommendation. I feel ok without it - I don't have any of the symptoms of a low potassium level that I found on Dr. Google...

Should I really be worried about this? Has anyone else who had a low potassium level found good foods to eat for this?

    Eat a couple bananas, tons of potassium in them.

    If you are concerned, ask your doctor to run lab work to check your potassium levels. Potassium is not required on nutritional labels and is therefore missing for many entries in the database. You are likely getting more than what is showing on your diary entries.

    In summary, unless lab work confirms hypokalemia, I wouldn't worry about it.

    Get a blood test and have your doctor test your potassium levels. If you are low you can supplement with Potassium supplements or a multi-vitamin for women with Potassium. It is almost impossible to get enough Potassium from food if you are on a calorically restricted diet.

    There are plenty of other foods which contain more potassium. I like bananas, but they pack a calorie punch when someone is trying to lose. I still fit them in occasionally, but there are many other options which (for me) work into my goals better.

    Bananas are calorically dense? That's a first I've heard of that.

    The bold above is most likely why OP is not hitting her potassium levels. Very few nutritional labels show it and very few entries in the database have it. You're probably getting much more than your food log is showing.

    I see what you are saying about the banana, but they have about 400mg each. Two would give me about 800 mg more. I have been about 2000 mg short each day. So even two extra bananas on top of what I already eat wouldn't put me all that close to the rec daily value.

    It would make sense if some of the dietary potassium wasn't in the data base so wasn't counted. It's the only nutrient that I am really low on and it doesn't make sense otherwise.

    Looking strictly at potassium versus calories, broccoli or potato are a better option. Depending on the OPs daily calorie goals, it could be difficult for her to eat a couple bananas each day, feel full, and still meet her nutritional requirements. It is an individual choice.

    Look at your entries and see how many of them have a zero or no value in the potassium entry. I'd be willing to bet it's the vast majority of them.

    Thanks everyone- I feel much more at ease about why the levels might be showing up as low even if they aren't. I might have my doctor check my blood level at my next checkup, but until then I won't worry about it so much.

    Good plan. This comes up a lot, so you are certainly not the only one surprised by it! :smile:

    The target is way too high. Shoot for less.

    Same thing happens to me. Logging shows I am way under RDA for potassium so I had blood work last week and it shows my potassium at normal level. Not sure why nutrition chart is so off in MFP. Now I never rely upon it.

    Try increasing your overall vegetable and fruit intake. It's not just about potassium. There are thousands of nutrients in whole foods that you won't get from a pill.

    Eggs, milk, fish and meat are also good potassium sources. Double whammy - you get your protein and potassium at the same time!

    I just ran into this same issue. In my case it might be a little more serious because I'm a ketogenic T2 diabetic who suffers from leg cramps. Leg cramps are usually caused by a lack of magnesium, and people in ketosis often have a hard time retaining magnesium and potassium. So the most popular solution, in our case, is to eat 1-2 cubes of bouillon per day, which adds enough sodium (1-2g) to retain the magnesium. On top of that, many of us supplement magnesium just to be sure. Those leg cramps in the middle of the night can be horrific!

    So what does this have to do with potassium? Even before I became ketogenic I would occasionally get leg cramps. When I did, I would take a single potassium capsule, only 99mg, and the cramp would go away instantly. The single capsule doesn't do anything when I'm in ketosis. But feeling that potassium has a roll in this leg cramp thing, seeing that I'm only getting about 2/3 of the RDA, and understanding that it would be very difficult to bring myself up to 100% by eating real foods with my restrictive diet, I've decided to supplement.

    Unfortunately, the RDA for potassium is 4700mg. Those 99mg capsules are a joke. So I've resorted to pouring 1/4 tsp Nu-Salt in with my daily bouillon broth. I also add seaweed for iodine, but that's another story.

    Tomato soup and baby russet potatoes. Banana too. But, potatoes are the best source (the skin). That's what I'm eating to hit my target. I don't recommend supplements.

    Yes, yes. Ding ding, winner. Nu Salt is the real potassium supplement.
