Check this out:
Serving Size: 1 Tbsp (9g)
Calories: 8
Fat: 0g
Protein: 0g
Carbs: 8g
…Fiber: 9g
What’s wrong with this picture?..
just some rounding down
could be non-usable carbs.
I’m confused? How the hell did they work that out?!
Hmmm…
9g serving, 9g of fiber, 8g of which are carbs.
Still…thinking…of…explanation!
Okay. Got it. This isn’t gum. It’s compressed psyllium husk, masquerading as gum, but as you chew it, exactly 1g gets caught in your teeth…hence, only 8g carbs.
Evidently, the fiber in your teeth is passed on to your toothbrush, or failing that your girlfriend during a smootch.
Any takers? No? Okay, it’s a friggin typo! Not that one? Hmmm…how about more BULLSHIT labeling? Yeah, that’s works!
Just thought I’d point that out; something I found funny 
fiber is undigestible. the calories from it arent counted because we cant break it down. so thats 4 calories from carbs and probably a minute amount from fat and protein to equal 8 calories. its not rocket surgery.
omg, seriously, dudes…they rounded down the other macronutrients!
calculate calories if there’s 0.4g of fat and 0.4g of protein. see what happens.
0.4<0.5 so they can round down to zero. it’s sooo simple.
0.4g fat = 3.6 cals
0.4g protein = 1.6 cals
Total = 5.2 calories
And what about the fiber? Fiber is a type of carbohydrate, right? So how can there be MORE fiber than carbs? Rounding or not…
oops! hhaha, didn’t catch the fiber thing smack forehead doh!
btw, what IS that stuff?
It is used as a thickening agent. Guar Gum is another that can be used. I use them to thicken broth or pan juices from roasted meat to make low carb gravy.
Also used to add a creamy texture to homemade ice cream.
