Default Validity of 1 and 2 hour tests

I have a serious potassium absorption problem so drink lots of V8 and OJ. Also eating potatoes, bananas and dried apricots are gone. But trying to get my potassium, my low sugar [50%] OJ produces a terrible one hour reading: 170 but only 115 at two hours. [pre drink was 105]

Do I need to panic about that one hour number [170] or does the two hour number [115] indicate my body is handling it?

[I'm also going to have 1/2 glass twice a day to see if that helps]

We know that organ damage starts to occur at BG levels above 140, so the 170 is of a little concern. As you state, though, your body is responding by reducing BG to a level within the standards of your meter. And potassium is critical to cardiac function.

I'm guessing from your continued use of OJ that supplemental (tablet) forms of potassium either are not well-absorbed or -tolerated? In that case, I would say it's worth trying to split up the doses. If that doesn't improve things, though, my non-medical $.00 opinion is that healthy potassium levels are worth a short hit on your BG. My opinion; that's how I would handle it. (Full disclosure: I am taking a potassium supplement [tablet] without much issue that I can trace to the supplement.)

Thanks. V8 is 850mg per glass and I often had three a day. [no longer] OJ is around 200 and I'm trying to balance that.

Pills are only 99 and wont take more than one without doc's okay. Bottle says only one per day, but I'm sure that's not a hard rule.

It's an issue because I've been rushed to ER twice from feinting from serious potassium problems. Time to see the doc.

Should have asked: how much potassium supp a day are you taking?

I'm taking 200 mg (okay, 198 mg) daily plus whatever I get in food (which is limited as I don't eat fruit, V8 juice, or that much of the more keto-friendly sources of K [spinach, avocados, tomatoes]). If it's a sweaty day of work, I might add another 99 mg; if I eat a spinach salad that day I'll likely skip one. I'm also on a blood-pressure medication that tends to keep K levels high. The RDA for potassium is 4,700 mg for adults so I don't think I'm going over even with this level of supplementation. It seems to be the amount that works for me.

I've found several potassium sources that I'd not considered so now have to go shopping. It's amazing how much is in nuts and above ground veggies.

I seriously doubt if many people get 4,700 mg / day.

I do, too. However, I know in eating keto I'm not eating several of the most popular sources, so I'm probably even further away from that 4,700 mg than most people.

I'm interested in some of the research I've come across indicating that the ratio between sodium intake and potassium intake is more critical than pure potassium intake, but I haven't had time to dig into those studies yet.

News to me. Let us know if you learn something we should know.

If you buy a Salt Substitute product like NuSalt or NoSalt, they are actually potassium chloride instead of sodium chloride.

Also, cream of tartar is very high in potassium.

Spinach is higher in potassium than a banana but most of us don't know how to fit enough spinach into our diets. I like to shred a pinch of spinach leafs into my meals, it will disappear into most. This is not enough but it gets me closer.

The ingredient charts show spinach have about 170 mg / cup, but how do you measure a cup when it can be very loose or kinda compressed. Best measure for 170 mg is 30 grams.

My fave K snack is PB [120 mg / Tbsp] and celery [160 mg per average 11-12 stalk] That's about two 5-6" long pieces and I use more like 2 Tbsps of PB on three stalks, or about 450-500 mg K.

Perfect for me.

I found way to increase spinach intake - I make a lc smoothie in AM and add around 2 cups of spinach leaves - it's quick and tasty...
