"I'll have the pink one." That's what my mom always says
when she is making her coffee. Of course she is referring to Sweet 'N Low, one
of several brands of artificial sweeteners. I have never liked the weird tangy
after-taste of artificial sweeteners, which has led to me using Stevia or agave
in my coffee.

These new low-cal sweeteners are derived from natural
substances but their newness on the market means they haven't
been well-studied for safety. According to Barry Popkin, a professor of
nutrition at the school of public health at the University of North Carolina at
Chapel Hill, even though the base comes from a nature, some sweeteners may have
undergone chemical processing to extract them from their original sources. This
process may affect their healthfulness.
Few details about the extraction process are provided by
manufacturers, but the FDA has reviewed data and considers most of them to be
generally safe. And the Center for Science in Public Interest (CSPI) believes
the natural sweeteners are safer than aspartame and saccharin (the chemicals
found in artificial sweeteners). The exception is Nectresse, a monk fruit extract.
CSPI says it has been poorly tested for safety but since it's derived from a
fruit, it is probably safe.
Don't get too excited about them being low calorie. There
has been very little research done about how these sweeteners affect weight
loss.
"Our research shows that artificial sweeteners do
appear to reduce the risk for weight gain when combined with a healthy,
well-balanced diet," Popkin says. The risk for weight gain and diabetes
with artificial sweeteners is because they may interfere with the physiological
responses that help regulate body weight and control sugar.

When we taste something sweet, our bodies expect actual
calories to hit our stomachs and we release insulin to prepare. But in the
absence of actual calories, the insulin and other hormones cause your blood
sugar to plunge and make you crave more sweets (i.e. overeat).
Experts think natural low-calorie sweeteners will have
the same effect since the sweetness will jump-start the chain reaction. They
may not be the best tool for weight management.
There is one tip - the overeating effect can be countered
if you consume food that contains fiber. The fiber keeps insulin levels steady
so blood sugar doesn't plunge.
