Default question about NET carbs!

ok I am slightly confused...I know if a label has carbs, then fiber, then sugar alcohols you subtract fiber and sugar alcohols from the carbs...but on most of my labels I don't see sugar alcohols..they look like this for example:
Carbs 6
Fiber 1
Sugars 2

But I think the sugars are sugar alcohols, since they are under the carbs, like the fiber and sugars are both indented under the carbs...so are these sugars really sugar alcohol? Just need some clarification! thanks

Hi Breakfastsurreal,

Here's a little info about sugar alcohols (its in FAQ's here on the boards)

ALL ABOUT SUGAR ALCOHOLS (MALTITOL, SORBITOL, ISOMALT , etc..)

These sweeteners are neither sugars, nor alcohols, but they are carbohydrates nonetheless. They are sometimes called POLYOLS, to avoid confusion. At the present time, they have not been legally classified for product labelling purposes, as are sugars, starch and fiber. So, some manufacturers are choosing to omit them from the total carb count in the nutrient data panel of the label (they MUST however declare the amount of sugar alcohol in the ingredient list). Because they aren't actually SUGAR, products that contain them may use the term "sugar free" on the label. Some manufacturers and distributors (esp. in Canada and Europe) are choosing to declare the full carbs in the nutrient data panel, and some diabetes associations and consumer groups are pressuring for gov't legislation to make this a legal requirement.

There are some claims that sugar alcohols don't have carbs, and therefore don't count; that they can be completely subtracted if listed on the label. This statement is not entirely "false" but it is misleading. Sugar alcohols do have carbs, and approx. 1/2 to 3/4 the calories of regular sugar. They are more slowly and incompletely absorbed from the small intestine than sugar, thus producing a much smaller and slower rise in blood sugar ... and consequently insulin. But this is a YMMV thing. Some Type 1 diabetics have reported that they sense an immediate "sugar rush" from eating even a small amount. Others notice no change, and absolutely no effect on ketosis.

Sugar alcohols do have carb calories, and the body will use these as fuel, or store as fat, whether or not insulin is involved. You need to look at the total CALORIES for one serving of the product. Subtract from this total the number of calories from any protein in the product (prot = 4 cal. per gm), then subtract the calories from any FAT in the product (fat = 9 cal. per gm). What's left is the calories from carbohydrate ... divide this remainder by 4 (carbs = 4 cal. per gm). If the number you get is bigger than the number of carbs declared on the label, the product has hidden carbs, and it's most likely the polyol. Calories do not just disappear into thin air!

The "laxative effect" happens for two reasons. First, because the sugar alcohols are not completely absorbed, they hold on to a lot of water in the bowel. This causes diarrhea. Another consequence is that when undigested carbs reach the colon, the normal bacteria present there go WILD --- resulting in unpleasant gas, and bloating. Sorbitol and mannitol are the worst offenders in this department, maltitol less so. The effect is dose-related -- you would be wise to pay attention to the serving size listed on the product label. This amount would be considered "safe" for the average adult -- make note of this before giving to a smaller child! Nothing like watching your kid doubled over with cramps and diarrhea because they ate too many "sugar free" sweets. To the best of my knowledge, sugar alcohols ARE safe for children, and pregnant/nursing mothers ... just keep an eye on the dose.

There are some newer sugar alcohols slowly making their way on the market, which have less laxative effect, and even less blood sugar and insulin consequence. Erythritol, isomalt and inulin are a few to watch for. There's another called HSH (hydrolyzed starch hydrolysate) also called maltitol syrup. The thing is, the different sugar alcohols have different properties, and can't be used for all things. Sorbitol is used in hard candies ... it produces a nice, clear candy that doesn't crystalize, and stays hard and dry in a humid environment. Because it doesn't crystalize, sorbitol is used in ice cream to help it stay creamy. Mannitol also can absorb a lot of moisture before it gets damp and sticky, therefore it's used to "dust" sticks of gum, to keep them dry. Maltitol and erythritol provide smooth bulk, and are ideal for chocolates and soft candies to give a creamy "melt in the mouth" quality.

Sugar alcohols are not acted upon by bacteria in the mouth, and therefore do NOT cause tooth decay. In fact, xylitol actually INHIBITS oral bacteria, and is often used in sugarless mints and chewing gum for this reason.

BOTTOM LINE

We are all individuals, and our bodies will react differently to these products. Depending on other factors, such as what else we've consumed along with it or on an empty stomach, we may even find ourselves having totally different reactions each time we eat it. So proceed with caution.

Be aware that there is potential to cause a rise in blood sugar and insulin ... although slower. Also the possibility to knock you out of ketosis, if you're following a ketogenic program such as Atkins. Pay attention to the serving SIZE. A 45-gram (1-1/2 oz) chocolate bar may state on the label that one serving is 15 grams (1/2 oz). That's only 1/3 of the bar, so keep that in mind when you're about to chow down.

If you are following Induction level low carb eating, it would be wise to avoid these products until at LEAST the 2 weeks are up, and your body's metabolism is settled well into ketosis and fat-burning mode. Same for other low carb programs, which may not be ketogenic, but do have strong effects on the metabolism (eg. Protein Power, Carb Addicts). Give your body the chance to adjust to the new WOE first, then cautiously add these products.

KEYWORD moderation. Most low carbers find they can indulge very occasionally in a polyol-sweetened treat without consequence to their weight loss effort, and perhaps a mild laxative effect or some gas. It's a trade-off, but helps to stave off cravings for high-sugar goodies. A problem could develop though, for someone with carb-addiction .... these candies just become a substitute addiction. Also, the sweet taste can trigger EMOTIONS (for an addict) that will result in a "rush" of hormones and enzymes in the body, ultimately leading to an insulin spike ... and fat STORAGE. And remember that candy is NOT a meal substitute. There's little or no protein, vitamins or essential fatty acids.

COUNTING NET CARBS:

Net Carbs: The Carbohydrates that can be Digested and processed by the body as dietary carbohydrate and therefore directly impact Blood sugar.

The figure for Net Carbs represents the total grams of carbohydrate minus grams of Fiber.

Net Carbs are the only carbs that you need to count when you do Atkins.

There are different theory's about sugar alcohols but your best route is to stay away from them.

Breakfast-I don't think anyone actually answered your question. If there are sugar alcohols in your food, they have to say "sugar alcohols". If it just says sugars, that isn't the same thing. You don't get to subtract those. Someone correct me if I'm wrong.

thanks petra, i asked the same question on another atkins forum and i was informed that they dont count...Oh well I screwed up...but at least I didn't do it on purpose, it wasn't like I was giving in to temptation or anything!
Just curious, have you guys ever "accidently" eaten the wrong things before? I like to eat a lot of easy meals so a lot of times its difficult for me to stay on a list of individual foods...it's a lot easier to buy premade things, or mixes (such as my marinera sauce I goofed up with today!)
It shouldn't stall me as long as I am staying under my 20 carbs today right?
Also, are we allowed any sugars? or should we just not eat things with sugars in the label at all? I have noticed a lot of things have sugars in them, but aren't something you would think of as a sugary food...green beans for example

You should be okay as long as you stay under your 20 grams of carbs. Some vegetables are naturally high in sugar like tomatoes and onions so you should eat those sparingly. Anything that has refined sugar in it you should definately avoid and somethings you would never imagine have refined sugar in them. Sometimes they go by other names like dextrose, corn syrup, fructose, etc. Anything that ends in "ose" is likely a sugar. The one exception you can consider is sucralose which is the name chemical name for splenda.

Some people can eat sugar alcohols w/out a problem. So those people can subtract them from the carb count. Some eat sugar alcohols and have weight stalls. So they have to count them. So it depends on your body whether you can eat them or not. If you're just starting out then it's best to stay away from them. And yup, it's easy to mistake something and eat the wrong thing. I've done it a lot

IMHO, sugar alcohols should be counted as a carb and not subtracted.

Brenda do you remember the thread we had on the sugar alchocols counting or not counting? I'm gonna see if I can find it.
