Protein Bars nutrition

Hi guys

Normally when looking at foods and the macronutrient breakup it is

1g protein = 4 calories
1g carbs = 4 calories
1g fat = 9 calories

I noticed that with alot of protein bars it always doesnt quite add up

Example:

BSc-Hydroxyburn-Protein-Balls-Nut-Panel.JPG


BSC Protein Balls

25g Protein
3.5g carbs
8.4g Fat

Approx 190 cals on the above but it is 270cals


Can someone explain to me what makes up the residual cals? And is this a good or bad thing of which components make up the residual?

you will notice that the total carb count in that protein bar does not include the dietary fibre count,which is added separately.
This happens a lot with Australian products. They often report Net Carbs in the total carb count.

Fibre can account for anywhere between 2 to 6 kcal per gram of fibre depending on the type of fibre. I usually average it out to 4kcal.
If you include this, it should add up.

There is also the presence of naturally occurring alcohols which may or may not add further kcals per gram.

hope that helps :)
 
Thanks Chocchillimango

That clears it up a bit!

That's a bit deceiving then that they market it as low carb when they are just really reporting net carbs to other products who report total carbs!
 
I've also noticed that the numbers on nutrition panels often don't add up. I think they often are just inaccurate.

But there are food items that have no fat, protein, or carbs yet they have energy value. consider alcoholic spirits - while the alcohol is a carbohydrate in the chemical sense its not a sugar / starch in the way carbs are defined in food circles. So rum has 212 cals per 100g yet will be listed as having zero fat, protein and carb.

Maybe your example has a lot of compounds that have energy value but no nutritional value like the rum. Sorry but I have no idea what they could be in your case.
 
How is it misleading to leave out firbe? Polydextrose is indigestible. It forms part of the calorific content, but the body can't use it.
