Sweetener 101: Know your Sugar
Substitutes, part 1: Sugar Alcohols
Today, the
sugar substitute market continues to grow exponentially. Sugar
substitutes are commonly
used to control and regulate blood sugar levels in diabetics (as well as
pre-diabetics). They are also are very common for weight
loss and obesity prevention. As the regular sugar markets
continue to be vilified by the mass media outlets
as the cause of obesity in the US (believe me, high sugar
diets are definitely top contributors,
however, they are many other responsible
variables for the obesity crisis), sugar substitutes,
especially the natural ones, are growing as household
names. So what exactly are these sweeteners and where do they come from?
Sugar Alcohols
Sugar alcohols aka polyols (can commonly be identified
by the “ol” at the end ) are
naturally occurring carbohydrates that cannot
be completely absorbed by the small intestine into
the blood . Note: not to be
confused, sugar alcohols do not contain the ethanol that is found in alcoholic beverages. They come
from plants, typically fruits. When metabolized,
they require the use of little or no insulin. Sugar alcohols contribute
fewer calories than other sugars about 2 kcal/ g compared
to 4 kcal/g from regular sugars.
The USDA classified sugar alcohols as nonnutritive sweeteners (NNS) as opposed to regular sugars as nutritive
sweeters. They are regulated by the FDA as food additives or generally
recognized as safe (GRAS).
Here is a list of the most common sugar alcohols: mannitol, sorbitol, xylitol, lactitol, isomalt, maltitol and
hydrogenated starch hydrolysates (HSH). With its growing popularity,
xylitol is the most common due to its similarities to sucrose.
Pros:
- Reduced
carbohydrate content.
-Reduced
caloric content (compared to regular sugar).
-Has been
shown to prevent dental carries (does not cause cavities, but in fact, help
prevent them).
Cons:
-Can potentially
cause adverse GI affects (including boating and diarrhea).
-Tend to be
more expensive than regular sugar products.
-Many foods
that contain sugar alcohols tend to have a higher fat and/ or sodium content to
make up for lost flavor.
-May not be
able to completely curve sugar cravings (besides, our bodies need some glucose
to function optimally).
-Xylitol has
been shown to be fatal to
canines. Although research is not extensive, there have been studies that linked
xylitol consumption to liver failure in dogs. Please be mindful!
