Artificial
sweeteners are in thousands of products that we consume everyday, especially
when selecting diet products. Most commonly, sweeteners like Splenda and Equal are used to replace sugar in people's every day coffee dose. But before you rip open that sachet, you may want to know a few more of the facts.
Some people
can be sensitive to artificial sweeteners and experience symptoms such as
headaches and upset stomach, but otherwise, there is no credible information
that aspartame — or any other artificial sweetener — causes brain tumors, or
any other illness, says registered dietitian Wendy Vida. In saying that, there is no credible research to support these are safe for your body either. Artificial
sweeteners are made with chemicals and researchers still don't know what
effects these chemicals have on our bodies long term.
Since artificial
sweeteners are so much sweeter than sugar, a very small amount is needed to
achieve the same sweetness one gets from sugar. The theory is, if used normally,
the amounts you take in of these sweeteners is so minuscule it cannot cause
harmful effects.
Splenda
Splenda was invented by scientists trying to find a better pesticide.
Splenda is "made from sugar" because the manufactuers take a sugar
molecule and substitute three of its atoms with chlorine. Chlorine when
ingested in your body turns to methanol then in turn gets absorbed as
formaldehyde, which is the same kind of stuff used to embalm and preserve
bodies or to make nail polish. Slightly alarming.... However, the FDA confirms
Splenda is safe to for human consumption. There are many arguements against the
FDA's standpoint, as can be imagined when looking at Splenda's origins and the
lack of research or studies on its effects on humans.
The manufacturer's own short-term studies showed that very high doses of
sucralose (far beyond what would be expected in an ordinary diet) caused
shrunken thymus glands, enlarged livers, and kidney disorders in rodents. The
FDA decided that because these studies weren't based on human test animals,
they were not conclusive. However, rats had been chosen for the testing
specifically because they metabolize sucralose more like humans than any other
animal used for testing. Hmm.
Aspartame
About 6000 products, including diet soft-drinks, gum, candy, yoghurt
and Equal all contain aspartame. It's 200 times sweeter than sugar, and is
the most sweet tasting of any artificial sweetener. It's a synthetic
chemical combination that is comprised of approximately 50% phenylalanine,
40% aspartic acid, and 10% methanol.
Current evidence does not support this idea that aspartame could cause
cancer, or that it is unsafe. According to the American Dietetic Association,
aspartame’s safety is documented in more than 200 objective scientific studies.
The FDA has concluded that aspartame is safe, and that there is no strong data
to say otherwise.
In 2007, the most comprehensive look at the
research was conducted, and the conclusion was, again, that aspartame is safe.
An important caveat to that research – it was paid for by the company
Ajinomoto, which makes aspartame. This question of bias results is a common
issue in the studies of artificial sweeteners. There is a lot of scary evidence
out there to report the harmful effects of aspartame, including headaches,
birth defects, cancer, brain tumours, digestive problems and more.
When a product is so widely used, it often happens
that there is some scientific scrutiny. So I would imagine this debate and
these studies will continue for quite a while. With any artificial sweeteners,
the best approach is to use in moderation. The FDA recommends a daily intake of
no more than 50 mg of aspartame per kilogram of body weight. That amounts to 22
cans of diet soda for a 175-pound man, and 15 cans for a 120 pound woman.
