Eating Soda bread and no spikes?

My fasting and PP figures are pretty good these days (low-carb diet, exercise and 2x 250ng Met).

Today, since the weather (unusually for a bank holiday weekend!) was quite fine, we had a picnic style lunch out in the garden.

Bread spiked me pretty badly when I first tested, but I figure I can withstand that very occasionally, so we had some lean chicken and just a tiny amount of several types of cheddar on soda bread (minimal fat, so I don't expect any 'pizza effect') also some pickled onions, celery, drank only orange juice.. Had some chili marmalade on the bread too.

Due to a sudden wasp invasion, we ended up scoffing the food pretty quickly.

According to online sources, I probably ate 80-90g of carbs in the bread and yet here's what happened:

before eating: 4.2
30 mins after : 5.4
60 mins after : 4.6
90 mins after : 4.5
120 mins after : 4.3

I'd not done any exercise, so I'm at a loss to understand why I didn't spike - is soda bread (small local bakery, rather than supermarket fare) substantially lower GI or otherwise better for BG?

Rankin Irish Brown Soda Bread 400g shows a carb content 161.2g per loaf !!! The figures just don't seem to add up ??

It was an irish brown soda bread, and I ate around two thirds of the loaf - once I got started, it turned into one of the 'yummy can't stop' moments... so you can see why I'm puzzled.

Not that I'm unhappy, mind - just puzzled!

To reah it's highet Bg in 30 minutes, the GI must be quite high. You obviously didn't eat too much of it.

But that's why I'm puzzled, since I ate around two thirds of the entire loaf!

Hi Markd. If you have this again, try testing after 3 hrs. It may well be that it is very slow to be absorbed in the bloodstream ? I couldn't get anything like those numbers after eating that ?

Great for you though if the numbers are all correct.

I did do a final test at two and a half hours - and it was 4.2 - couldn't do a three hour test as I was heading out to the pub!

Seems a bit unlikely that it would trend up again that late?

Three pints of real ale later and it is soon time for bed...

A bit of a long shot but could the vinegar in the pickled onions have anything to do with it?
