Ideal blood sugar levels

by 169 · September 21, 2012 at 1:39 AM

I got a blood sugar tester for free, so due to curiosity I decided to measure some pre and post meal levels. But I can't seem to find anywhere what the ideal numbers are. I've looked through some of the big paleo-type blogs but it's like looking for a needle in a haystack. The westonaprice blog has a big fat article about ideal blood sugar but doesn't give any actual numbers anywhere.

Can anyone tell me more? What else is interesting about blood sugar levels?

Thank you!

Here's what Dr. Davis says on his blog (emphasis mine):

What are ideal blood glucose levels? From the above discussion, you can see that a perfect consensus does not exist. It is also clear that risks from both fasting and postprandial glucose are continuous with no clear cutoff between no risk and the beginning of risk. However, for our working purposes, the data suggest that ideal fasting blood glucose is 90 mg/dl or less; one-hour postprandial 100 mg/dl or less. At the start of your program, before weight loss, exercise, and the improved insulin responses of the Track Your Plaque diet have taken hold, one-hour postprandial blood glucose of ≤110 mg/dl is a good starting point. Long-term, ≤100 mg/dl is a better target that likely provides maximum plaque control and reduction of risk.

My fasting level is about 90; when I eat paleo, my post-meal bg stays about the same. Then there was the time I ate a Big Mac and fries right after the holiday and spiked a 157. Yeah, sometimes this testing can be useful even for the non-diabetic!

I'm going mostly low-carb now, but plan to see how I respond to starchier veggies soonish.

I've found the following graph from Wikipedia to be pretty helpful:

However, keep in mind that people who have been on Paleo for a while tend to have lower insulin levels and slightly higher fasting blood glucose--but with a lower HbA1c (glycylated hemoglobin), which is a much better predictor of long-term health than cholesterol levels, even in non-diabetics.

www.bloodsugar101.com is the website that can answer this question and more - like how to adjust your at home OGTT to compensate for eating low carb

http://chriskresser.com/how-to-prevent-diabetes-and-heart-disease-for-16 heck out Chris Kressers website for how he monitors blood glucose and what levels he recommends. I found it very helpful.

At wakeup and after exercise, my BG is 5.5 mmol/L (100 mg/dL), otherwise it seems to keep at a steady 3.8 mmol/L (68 mg/dL). Anything between 72 and 108 mg/dL is considered healhty.

Out of curiosity, I did an OGTT (75g dextrose dissolved into 300 mL water). One hour later I had 7.5 mmol/L (135 mg/dL). You're supposed to get under 8.6 mmol/L (154 mg/dL) after two hours, so I passed it.

If you read Swedish (or care to run it through Google Translate), http://kostdoktorn.se/blodsocker is an excellent resource.

According to this article from the Life Extension Magazine, the "optimal" fasting level is 70-85 mg/dL. I have seen other bloggers/commenters say "optimal" is <85 or <80.

Recommended levels are 72-100 mg/dL, fasted. Mine was 85 mg/dL. What does that tell me? I'm...not sure.

i am also wondering what ideal fasting bg should be. i recently tested at 92. is that slightly above what it should be?
