So, a few weeks ago, I received my latest shipment of chocolate Chip Cookie Dough Quest Bars. I noticed they had a slightly different taste and texture, but didn't think much of it, because I've noticed some variation in batches of Quest Bars before. But then I started getting really gassy in the past two weeks or so. Like really gross smelling gas and loose stool. After talking to a coworker who also eats Quest Bars, I realized that Quest Nutrition has been phasing out Isomalto-Oligosaccharide in all of their bars and replacing it with Soluble Corn Fiber. Now both of these are "fake" fiber and have their various issues, but at least the former didn't make me horribly gassy. I've now been soluble corn fiber free for a day and a half and the gas has stopped, so I know that was the issue.

I managed to find one more box of the old version of Quest Bars, but I'm very sad to have to be switching away from them. I loved them SO much. Now I'm trying Muscle Pharm's Combat Crunch bars and they are tasty, but very candy bar like, which can be cloyingly sweet. The also have slightly more calories and more net carbs than the Quest Bars. I guess I will have to keep searching for something that tastes good, has plenty of Protein, has few carbs, and doesn't make me sick.

Does anyone know if this is going to be used in all the flavours?

Oh, now I am depressed. I only have 4 bars left, checked the ingredients and they are the previous fiber ingredients. I was going to buy another box this week. Do I dare try the new soluble corn fiber ones? Maybe I can still find a box with the old formula, if not I guess I will buy one bar and try it to see how my body reacts. Thanks, @JamieLogical for the alert.

It is. I found a press release about it in my searching last week. But now I can't find it again. It started with any NEW flavors they were making (the first was S'mores), but now they are going back and converting all the old flavors.

Here's the blog post on the Quest Nutrition site about why they claim to have made the switch:

Well thats a downer for sure

It's definitely going to be in all be new ones and has been in the S'mores and chocolate Mint since they introduced them.

After researching both types of Fiber I am actually thinking I like the change in theory... But I have yet to try one to see if it agrees with me. Sorry it didn't with you!

And yeah @@CowgirlJane is right they can be a trigger for many, but I successfully used them throughout my losing phase and use them in maintenance now.

@@jess9395 Yeah. Clearly the change won't have a physical effect on everyone. Some people's bodies tolerate some things better than others. Like, the Chocolate Chip Cookie Dough bars have always had Erythritol in them and some people have digestive issues with that. It was never a problem for me. Just bad luck for me that they decided to make this change and soluble corn fiber seems to be something my body can't handle.

@@JamieLogical If you could STOP trying to ruin my life that would be great!

Ha! The good news is, not everyone has an adverse reaction to the soluble corn fiber, so you might be fine!

_{Thank you for the heads up. I love these bars and haven't had any issues with them. I just bought one yesterday and ate it for Breakfast this morning and haven't had any issues yet. Lets hope for the best}

I knew of the change and have been so sad.....but I did not connect the dots to figure out why my gas has been so horrible!! So sad. :-(

For several weeks now, I've been trying a variety of the Quest bar flavors. I had not paid much attention to the ingredients label until I read this post. My most recent order of bars does have the soluble corn fiber, but I can't say I've noticed any difference digestively That being said, because I read the ingredients label today, I see that these bars also have Stevia in them, and not just sucralose. I've never had any problems with sucralose and am a fan, but have had problems in the past when using Stevia as a sweetener. Could it be that for some people it's the Stevia that's causing the problems? Just wondering out loud.

@@MrsSugarbabe There are a variety of ingredients in Quest Bars that may or may not sit well with certain people. Some of the flavors use Erythritol, a sugar alcohol that has been known to cause diarrhea and bloating in some people. Some use artificial sweeteners including Stevia and Sucralose, which many people have issues with. For me, none of those ingredients had caused any problems. I've been eating the Chocolate Chip Cookie Dough bars for almost a year now. It was just the switch over from IMO to soluble corn fiber that started causing me problems. I imagine it will be just fine for a lot of people. I know that for many people, the S'mores flavor has been their favorite and that's one that's been using soluble corn fiber since the beginning.

sure enough, checked my smores quest bars and they have the corn fiber but my box of cookies and cream doesn't. Thankfully I have only one smores bar left. Quest bars are the only ones that taste good to me.

Thanks for posting this. I just bought a box of Quest double-chocolate chunk bars at GNC yesterday. I'm going to check the ingredients when I get home, if it's got it, I'll return the box, and then try a single bar (on a day I don't have anywhere to go! haha) to see if I have the same reaction. I'm hoping not! I don't eat Protein bars much, but they are good to have around sometimes!

Funnily enough I just tried the quest pumpkin flavor yesterday. Brand new flavor that was just released today. I split the bar with my roomie so I didn't eat the whole thing, but I didn't notice any reaction. Maybe that's a good sign.

ETA: I just read the part about them already being in the s'mores flavor. I have never had a problem with the s'mores flavor so I think I should be good.
