Sweet Nothings: How Artificial Sweeteners Can Pack On The Pounds

We read it in newspapers, see it on the nightly news, even Hollywood is responding to it in various spin-offs of the NBC hit reality show “The Biggest Loser:” Obesity rates in both adults and children are reaching epidemic proportions. While the incidence of obesity and overweight Americans have spiked over the years, so has the trend of consuming ‘sugar-free’ foods. The number of Americans consuming sugar-free products increased from less than 70 million in 1987 to more than 160 million in 2000. Surprisingly, however, switching from sugar to an artificial, no-calorie sweetener may be thwarting your attempts to cut calories and actually cause your metabolism to slow down. And a slow metabolism can be a major factor in weight gain.

Do artificial sweeteners really cause weight gain?
A recent study by Purdue University found that rats given yogurt sweetened with saccharin (an artificial sweetener) consumed more calories and gained more weight than rats fed yogurt sweetened with glucose (a natural variety of sugar). This led researchers to believe that foods with artificial sweeteners, such as saccharin and aspartame. lead to greater weight gain than the same foods sweetened with high-calorie sugar.

How It Works
Artificial sweeteners may weaken the body’s ability to identify the delivery of calories into the stomach. When you consume glucose, found in foods and drinks, such as regular soda pop, your taste buds send a message to the brain that says sugar is on its way down to the stomach. Your brain then prepares your stomach to take in the sugar, while your metabolism prepares the body for the incoming calories. When the sugar is replaced by a no-calorie, artificial sweetener and the calories never reach the stomach, the body is left in a state of confusion. Over time, your body loses the ability to gauge caloric intake, which leads to a tendency to consume more food than needed and thereby gain more weight.

Of course, this doesn’t mean that you should always drink regular soda either, since the high-fructose corn syrup also packs a high-caloric punch. There are other healthier, more natural alternatives that are low in calories and just as sweet.

Artificial sweeteners to avoid:
Aspartame (NutraSweet/Equal)
Saccharin (Sweet’N Low)
Artificial sweeteners to use with caution:
Sucralose (Splenda ) –- chlorinated
Sucralose is 600 times sweeter than sugar on average and has no calories
Acesulfame K (Sweet One or Sunnette)


Switching to natural sweeteners:
Replacing artificially-processed sugars with natural sweeteners is the best solution, so consider adding one or more of the below to your diet:

Stevia -- extracted from a plant grown in South America

Does not raise blood sugar levels
Non-caloric
10 to 15 times sweeter than sugar
In cooking: 1 packet Stevia = one packet sugar, or 1/4 tsp. liquid Stevia = 2 tsp. sugar

Agave nectar -- juice is extracted from the core of the agave plant

Has minimal effects on blood sugar and insulin release
Contains calories
In cooking: 1/3 cup of agave syrup = 1 cup of sugar

Honey -- produced by honeybees
Contains a number of nutrients which include sugars, such as fructose, glucose, sucrose, maltose, lactose and other disaccharides and trisaccharides
Raises blood sugar levels
Honey may contain minute quantities of clostridium botulinum spores and should not be fed to children under one year of age
Raw: may contain bits of wax, insect parts and other small detritus
Filtered: This is raw honey that has been warmed to make it easier to filter out small particles and impurities. Other than being somewhat cleaner than raw honey, it is essentially the same. Most of the trace amounts of nutrients remain intact.

Sucanat -- organically grown, freshly-squeezed sugar cane juice, evaporated by a special Swiss process
In its natural state, it is highly nutritious, since the molasses has not been removed
Raises blood sugar levels
Use in place of brown sugar for an extraordinary flavor

Cane Sugar – produced from the sugar cane plant
Cane sugar does not go through the same refinery process as sugar, so it maintains it retains more of the nutritents.

Natural sweetener to avoid:
All natural sweeteners are not created equal and all though they are technically considered “natural”, they should be avoided.

High fructose corn syrup
The intake of soft drinks containing high-fructose corn syrup or sucrose has risen in parallel with the epidemic of obesity

“In 2000, the intake of added sugars for the average American was two and a half times that recommended by the Dietary Guidelines, and nearly half of the added sugars came from high fructose corn syrup,” according to the American Dietetic Association. These excess calories lead to obesity.

Table sugar (Sucrose) -- white table sugar is empty of all vitamins, minerals, fiber, amino acids and trace elements during the refining process


While all of us are in the need of something sweet once in awhile, the best suggestion is reaching for Mother Nature’s sweet bounty in the form of an apple, orange, peach, watermelon or any of the other tasty colorful fruit selections available.

Enjoy!
