New Quest Bars and Blood Sugar

grim_traveller

Thanks again to garber6th for pointing out the change in formula for Quest bars.

One of the issues that always came up with the old formula was the sugar spike that diabetics and some others would see after eating these, so I thought I would test the old and new formulas to see if there was a difference.

I did a short experiment comparing the old Quest bars, with iso-malto-oligosaccharides as the fiber source, with the new bar, with soluble corn fiber as the fiber source. Both bars were chocolate brownie, and both were eaten for breakfast at 7 am.

Day 1, old formula iso-malto-oligosaccharides bar:

Fasting blood sugar - 65
1 hour after Quest bar - 109
2 hours after Quest bar - 79

Day 2, new formula soluble corn fiber bar:

Fasting blood sugar - 72
1 hour after Quest bar - 83
2 hours after Quest bar - 79

It's obviously not a very scientific test, so take it for what it's worth. But Quest claims that the formula change fixes the blood sugar issues that some people had with the old formula. But from this little experiment, it certainly seemed to.

Thanks, Grim!

I am one of those who consistently saw a blood sugar "spike" increase of 40 mg/dL (typically) from just one Quest Protein bar (old formula--same Chocolate Brownie flavor) & after eating one, felt compelled to have another & another and so on. I'm glad to see the new formulation appears to be better for diabetics. I'll have to try them again sometime but I think I'll wait until I loose more weight & get my binge eating under better control (I had no control over binge eating the prior formula Quest bars & finally got that "addiction" under control again & just don't want to risk it just yet).

That Quest bar flavor (Chocolate Brownie) along with PB&J are my favorite Quest Bar flavors. How did the taste compare between the two formulations you tried?

There is a difference in taste. I prefer the prior version, but there isn't much difference.

Yeah, it's tough to get the Quest bar monkey off your back. I'd pounce on a box of them like a monkey on a cupcake. And before you know it, I'd be out robbing gas stations and liquor stores to get more Quest bar money.
