What are sugar alcohols in protein bars, and are they bad for you?
Sugar alcohols are carbohydrate sweeteners such as maltitol, erythritol, sorbitol, and xylitol that FDA permits as sugar substitutes; they contain no drinking alcohol. They are not banned, but FDA requires foods likely to supply large daily amounts of sorbitol or mannitol to state, “Excess consumption may have a laxative effect.” Tolerance varies by person and amount.
Protein bars use sugar alcohols to add sweetness and bulk while keeping the Total Sugars line low. FDA describes them as slightly lower in calories than sugar. On the Nutrition Facts panel they count toward Total Carbohydrate but not toward Total Sugars or Added Sugars.
How do you spot sugar alcohols on a protein bar label?
Read the ingredient list for erythritol, maltitol, sorbitol, xylitol, isomalt, lactitol, or mannitol. A separate Sugar Alcohol line on the Nutrition Facts panel is voluntary unless the label makes a claim about sugar alcohols or sugars, so a bar can contain them without that line. Allulose is classified as a rare sugar, not a sugar alcohol.
Why do protein bars say they contain alcohol?
The name describes chemical structure. FDA's nutrition labeling rule defines sugar alcohols as saccharide derivatives in which a hydroxyl group replaces a ketone or aldehyde group. They are not ethanol and do not make a bar an alcoholic product.
When does FDA require the laxative-effect statement?
Under FDA's food regulations, a food whose reasonably foreseeable consumption may result in a daily intake of 50 grams of sorbitol, or 20 grams of mannitol, must bear the statement “Excess consumption may have a laxative effect.” This page relies on that regulatory statement and does not rank sugar alcohols against each other.
Does Genesee use sugar alcohols?
No sugar alcohol is listed on Genesee's current labels. The bars are sweetened with raw honey, plus coconut sugar in Coffee Latte's chocolate chips and cane sugar in White Chocolate Toffee's white-chocolate chips. The tradeoff is real sugar: 12-14g total sugars and 11-13g added sugars per 60g bar, depending on flavor. Recipes and labels can change. Check the package you receive for the current ingredients, nutrition facts, allergens, and caffeine disclosure.
Common questions
Are sugar alcohols bad for you?
+
FDA permits them as sugar substitutes. Some people notice digestive effects at larger amounts, which is why FDA requires a laxative-effect statement on foods likely to supply 50g of sorbitol or 20g of mannitol a day. Individual tolerance varies.
Is erythritol a sugar alcohol?
+
Yes. FDA lists erythritol alongside sorbitol, xylitol, lactitol, mannitol, and maltitol as examples of sugar alcohols used as sugar substitutes.
Do sugar alcohols count as sugar on the label?
+
No. They count toward Total Carbohydrate but not Total Sugars or Added Sugars. A Sugar Alcohol line is required only when the label makes certain sugar or sugar-alcohol claims.
Is allulose a sugar alcohol?
+
No. Allulose is classified as a rare sugar. If you avoid it, read the ingredient list, because it will not appear on a Sugar Alcohol line.
