I
started out with the more familiar ones. Sucralose is the most recently
approved sugar substitute and is made from a process that begins with sugar. It
is about 600 times sweeter than sugar and extremely stable, which is why it is
used in so many packaged foods, including dairy foods. Acesulfame-K is 200
times sweeter than sugar and is often used in combination with another sugar
substitute. It, too, does not break down during cooking. Aspartame is 200 times
sweeter than sugar. It contains the two amino acids, phenylalanine and aspartic
acid. Aspartame, however, is not stable at extreme temperatures. And the last
of the FDA-approved sugar substitutes is saccharin. It is 200 times sweeter
than sugar and very stable in foods. Unfortunately, it had received so much
negative press in earlier years that many consumers are saccharin phobics,
including the mom I was talking to, as she quickly informed me.
I talked about sugar alcohols or polyols. I emphasized how many occur naturally
in fruits. She interjected with: I hear they cause bloating, gas and laxation.
I promptly responded with an everything-in-moderation comeback. I pointed out
that erythritol is recognized by the natural foods community as being an
all-natural polyol, unlike many of the others. And, because erythritol is
absorbed by the bloodstream before it enters the large intestine, it does not
normally cause the undesirables she mentioned.
A glance at the time clock told me I had only a few more minutes to try and get
her to think like a food scientist and not a stay-at-home mom who reads way too
many articles on rights and wrongs. So, I brought up stevia. This natural
alternative sweetener comes from the plant Stevia rebaudiana and has been used
as a sweetening ingredient in foods and drinks by South Americans for
centuries. There are no reports of any plant toxicity to the consumers.
Stevia has been added to a number of food products in Japan since the mid
1970s. No indications of any significant side effects have yet been reported
after more than 20 years of use. Similarly, no reports of any adverse reactions
to stevia have been reported in the United States.
Stevia is 300 times sweeter than regular sugar, with minimal aftertaste. Stevia
extract has no calories. Stevia extract is suitable for diabetics and those
with high blood pressure. Stevia does not cause tooth cavities, it is heat
stable and readily blends with other sweeteners.
The stevia story gets even better. Independent researchers’ preliminary
scientific studies show stevia may improve the function of cells required for
insulin production in the pancreas. It may also improve glucose tolerance in
people with diabetes. Unlike any other sweeteners, stevia has been reported to
possess anti-viral properties. Preliminary evidence also suggests stevia
possesses blood pressure lowering properties and may be a useful treatment for
hypertension.
FDA does not allow stevia to be called a “sweetener” and be used as such, since
sweeteners are food additives and stevia is not an approved food additive. It
must be classified as a “dietary supplement” and the application must call
itself a supplement, even if it resembles a food. I told her she can expect to
find it in more and more products in the near future. It’s even sold by itself
at natural foods stores.
As the buzzer rang, she appeared to be stumped by this news of stevia. When we
got up to reclaim our sons, she said: Well, I am still not going to buy
anything with high-fructose corn syrup. I sighed.
