I’d like to start off the day with a real sweet post. Today, sugar gets its time in the spotlight as I present the facts on the effects of sugar and its artificial twin in regards to safety and weight gain. Are artificial sweeteners safe? Should I use them? Let’s shed some light on this very controversial topic and try to set the record straight.
In recent history, people’s penchant for the sweet stuff (sugar) has garnered enormous profit to industry producers as well as the medical community that treats the illness and diseases it creates. This makes finding accurate information on the effects of artificial sweeteners dubious at best. At least we can all agree that sugar, as it is typically presented, is highly addictive, destroys insulin metabolism, corrupts the immune system and is arguably the single greatest cause of health impairment and degenerative disease on the planet. So why all the fear mongering over artificial sweeteners? Why aren’t we more concerned about getting rid of sugar itself?
Artificial sweetners certainly have their share of critics in the health industry but what is the source of their bias? Can they lay claim to supportive scientific research? Usually these critics fall short in that regard and fail to weigh the facts thouroughly before offering their judgment. Their arguments tend to be based on hearsay and conjecture, rather than on an actual experience of intolerance or scientific fact. Certainly some people may be to intolerant to some of these substances, but we shouldn’t jump to conclusions without weighing the evidence first.
Why don’t we just eat natural whole foods?
Many opponents of artificial sweeteners will claim they are unnatural and therefore unsafe. However, they are often much safer than many common natural foods, and are definitely safer than luncheon meat, refined breakfast cereals, pasteurized milk and 99% of most sugar sweetened junk food. It is certainly not biologically necessary to consume artificial sweeteners but if you include high levels of “natural” sugars in your diet, such as fructose and sucrose, you may consider replacing them with artificial options from time to time.
Consuming too many refined sugars contributes to the formation of Advanced Glycation Endproducts (AGEs), which are known to accelerate aging in the body and increase biological age. Artificial sweeteners do not. AGEs produce free radicals, deplete glutathione, damage mitochondria, stiffen arteries and damage proteins such as albumin, collagen and hemoglobin.
Examples of Common Articial Sweetners
- Sucrolose (Splenda)
Sucrolose is calorie-free and 600 times sweeter than sugar (sucrose), which is why a little goes a long way as a sweetener. The body cannot break down or absorb sucrolose. Thus, around 98% of it exits the body (via urine) and the remaining 2% is “biotransformed” into other substances by the body and quickly eliminated. More than one hundred studies have been conducted to determine the biological fate of sucrolose in animals and humans, all of which demonstrate its safety. An additional 40 environmental studies show it is safe for plant and aquatic life. It is not carcinogenic and has no negative effect on reproductive performance or the nervous system. The Allowable Daily Intake (ADI) of sucralose is 15 mg/kg of bodyweight/day.
- Acesulfame Potassium
Acesulfame Potassium is a non-caloric sweetener and is approximately 200 times sweeter than sugar. It is often combined with other sweeteners to enhance flavor. Although it is absorbed from the GI tract into the bloodstream, it is not metabolized and is excreted from the body unchanged within 24 hours. Numerous studies have confirmed the safety of its use. It is not carcinogenic, is safe to consume during pregnancy and is not damaging to DNA structures. The ADI is 15 mg/kg of bodyweight per day.
- Aspartame (NutraSweet, Equal)
Aspartame is around 20 times sweeter than sugar. Unlike sucrolose, aspartame can be absorbed into the bloodstream. Its broken down into 3 constituents: aspartic acid, methanol and phenylalanine and provides 4 cal/g. The main concern with aspartame surrounds methanol. Our bodies produce methanol naturally when we digest food, at about 10 mg daily. Most aspartame sweetened beverages contain about 55mg/liter. In detailed studies conducted to determine how ingestion of aspartame influences plasma levels of methanol, it failed to alter blood levels or produce any adverse effect.
If aspartame is exposed to heat, it is broken down into a substance called diketopiperazine. Animal toxicity studies show that even if all the aspartame were converted to diketopiperazine in a beverage, the amount would be well below the established ADI for this substance (3,000 mg/kg). However, this metabolic by-product still remains suspect as a causative agent for adverse reactions in a small percentage of aspartame consumers.
Conclusion
At the end of the day, you need to decide if artificial sweeteners are right for you. This post was only intended to open your eyes to some of what’s out there. There are many more sweeteners and many more in development. There will no doubt be many more studies regarding their use and safety. Keep up to date, stay informed and always weight the facts. In a nutshell, if you don’t want to use artificial sweeteners, then don’t. Personally, I use them almost daily to help control my sugar intake and satisfy my insatiable craving for Diet Coke. I’ve never had any adverse reactions and am currently enjoying the peak of health and fitness in my own life.
