New Splenda Studies Confirm Its Dangers

New Splenda Studies Confirm Its Dangers

Urine and feces were collected daily from each rat, and were analyzed using ultrahigh performance liquid chromatography tandem mass spectrometry (UHPLC–MS/MS), which “revealed two new biotransformation products that have not previously been reported.”

Research Calls for New Safety Review of Sucralose

The two metabolites are acetylated forms of sucralose that are lipophilic, meaning they dissolve in and combine with fats. Sucralose itself is far less lipophilic, which has been part of the safety argument. According to the authors:

“These metabolites were present in urine and feces throughout the sucralose dosing period and still detected at low levels in the urine 11 days after discontinuation of sucralose administration and six days after sucralose was no longer detected in the urine or feces.

The finding of acetylated sucralose metabolites in urine and feces do not support early metabolism studies, on which regulatory approval was based, that claimed ingested sucralose is excreted unchanged (i.e., not metabolized).

The historical metabolic studies apparently failed to detect these metabolites in part because investigators used a methanol fraction from feces for analysis along with thin layer chromatography and a low-resolution linear radioactivity analyzer.

Further, sucralose was found in adipose tissue in rats two weeks after cessation of the 40-day feeding period even though this compound had disappeared from the urine and feces.”

So, not only is sucralose metabolized, these metabolites accumulate in your fat tissues, where they remain for “an extended period of time” after you stop consuming sucralose. In all, these findings led the authors to conclude:

“These new findings of metabolism of sucralose in the gastrointestinal tract and its accumulation in adipose tissue were not part of the original regulatory decision process for this agent and indicate that it now may be time to revisit the safety and regulatory status of this organochlorine artificial sweetener.”

Sucralose Is Not an Inert Compound

Previous research has also noted that sucralose is not a biologically inert compound, as claimed. In the 2013 paper,6 “Sucralose, a Synthetic Organochloride Sweetener: Overview of Biological Issues,” the authors state, in part:

“Sucralose and one of its hydrolysis products were found to be mutagenic at elevated concentrations in several testing methods … Both human and rodent studies demonstrated that sucralose may alter glucose, insulin and glucagon-like peptide 1 levels. Taken together, these findings indicate that sucralose is not a biologically inert compound.”

Importantly, the study also notes that “Cooking with sucralose at high temperatures … generates chloropropanols, a potentially toxic class of compounds.” Yet, Splenda is frequently recommended for cooking and baking,7 and is often used in processed foods in which high heat was involved.

Chloropropanols, which are still poorly understood, are thought to have adverse effects on your kidneys and may have carcinogenic effects.8 However, it’s worth noting that chloropropanols are part of a class of toxins known as dioxins, and dioxins are known to cause cancer and endocrine disruption.

Sucralose May Cause Liver Damage With Regular Use, and More

Another study9 published online August 2, 2018, in the journal Morphologie, found sucralose caused “definite changes” in the liver of treated rats, “indicating toxic effects on regular ingestion.” According to these researchers, their findings suggest “sucralose would be taken with caution to avoid hepatic damage.”

In other words, regularly using Splenda could damage your liver. Here, adult rats were given a much higher (yet nonlethal) oral dose of sucralose — 3 grams (3,000 milligrams) per kilo body mass per day for 30 days, after which the animals’ livers were dissected and compared to the livers of unexposed controls. According to the authors:

“Experimental rats showed features of patchy degeneration of hepatocytes along with Kupffer cells hyperplasia, lymphocytic infiltration, sinusoidal dilatation and fibrosis indicating a definite hepatic damage on regular ingestion of sucralose. Sinusoidal width was also found to be increased in experimental animals as compared to controls.”

Studies have also linked sucralose consumption to:

Genotoxicity (DNA damage) and potentially adverse epigenetic effects.10 According to this paper, the acceptable daily intake set for sucralose may in fact be hundreds of times too high to ensure safety
Shrinkage of the thymus, up to 40 percent11,12
Enlargement of the liver and kidneys13,14
Calcification of the kidneys15,16
Increased leukocyte populations (immune system cells) in the thymus and lymph nodes17
Migraines18
Altered glucose, insulin and glucagon-like peptide-1 levels and responses,19 which raises your risk for Type 2 diabetes.

A study20 published in the journal Diabetes Care confirmed that, compared to controls, obese patients using sucralose experienced a greater incremental increase in peak plasma concentrations of glucose, a greater incremental increase in insulin and peak insulin secretion rate, along with a decrease in insulin clearance.

According to the authors, “These data demonstrate that sucralose affects the glycemic and insulin responses to an oral glucose load in obese people who do not normally consume non-nutritive sweeteners”

Alterations in P-glycoprotein (P-gp) levels, which could result in medications used in chemotherapy, AIDS treatment and treatments for heart conditions being shunted back into the intestines, rather than being absorbed by your body21

Commonly Reported Side Effects of Splenda

If you start searching for adverse events reports, you’ll find scores of people reporting a variety of side effects from using Splenda. The following are common symptoms, usually noticed within a 24-hour period following consumption of a Splenda product:

Skin — Redness, itching, swelling, blistering, weeping, crusting, rash, eruptions or hives (itchy bumps or welts)
Lungs — Wheezing, tightness, cough or shortness of breath
Head — Swelling of the face, eyelids, lips, tongue, or throat; headaches and migraines (severe headaches)
Nose — Stuffy nose, runny nose (clear, thin discharge), sneezing
Eyes — Red (bloodshot), itchy, swollen or watery
Stomach — Bloating, gas, pain, nausea, vomiting, diarrhea or bloody diarrhea
Heart — Palpitations or fluttering
Joints — Joint pains or aches
Neurological — Anxiety, dizziness, spaced-out sensation, depression

Are You Having a Reaction to Splenda?

To determine if you’re having a reaction to artificial sweeteners — be it Splenda, aspartame or any of the others — take the following steps:

  1. Eliminate all artificial sweeteners from your diet for two weeks
  2. After two weeks, reintroduce your artificial sweetener of choice in a significant quantity (about three servings daily)
  3. Avoid other artificial sweeteners during this period
  4. Do this for one to three days and take notice of how you feel, especially as compared to when you were abstaining from artificial sweeteners
  5. If you don’t notice a difference in how you feel after reintroducing your primary artificial sweetener for a few days, it’s a safe bet you’re able to tolerate it acutely, meaning your body doesn’t have an immediate, adverse response. Just know that this doesn’t mean your health won’t be damaged in the long run
  6. If you’ve been consuming more than one type of artificial sweetener, repeat steps 2 through 4 with the next sweetener on your list

If you do experience side effects from an artificial sweetener (or any other food additive for that matter), please report it to the FDA (if you live in the U.S.). It’s easy to make a report — just go to the FDA Consumer Complaint Coordinator page, find the phone number for your state, and make a call to report your reaction.

Keep in mind that some medications may contain sucralose as well, even if it’s not listed on the label. If you continue to experience any of the symptoms above even though you’re avoiding Splenda and other artificial sweeteners, then it may be worth investigating whether any of the medications you’re taking contain artificial sweeteners.

Splenda Has Never Been Proven Safe for Human Consumption

The FDA claims they reviewed over 100 studies conducted on Splenda. What they don’t tell you is that a) only six of these studies were human trials — and only two of them were published before the FDA approved sucralose for human consumption — and b) the remaining animal studies actually revealed potential health problems, including:22

  • Decreased red blood cells (a sign of anemia) at levels above 1,500 mg/kg/day
  • Increased male infertility by interfering with sperm production and vitality, as well as brain lesions at higher doses
  • Spontaneous abortions in nearly half the rabbit population given sucralose, compared to zero aborted pregnancies in the control group
  • A 23 percent death rate in rabbits, compared to a 6 percent death rate in the control group

What’s more, the two human trials had a grand total of 36 subjects, only 23 of whom were actually given sucralose, and the longest of these trials lasted just four days and looked at sucralose in relation to tooth decay, not human tolerance.23

Even more shocking, the absorption of Splenda into the human body was studied on a grand total of six men. Based on that study,24 the FDA allowed the findings to be generalized as being representative of the entire human population, including women, children, the elderly and those with any chronic illness — none of whom were ever examined.

Healthier Sugar Substitutes

Two of the best sugar substitutes are from the plant kingdom: Stevia and Lo Han Kuo (also spelled Luo Han Guo). Stevia, a highly sweet herb derived from the leaf of the South American stevia plant, is sold as a supplement. It’s completely safe in its natural form and can be used to sweeten most dishes and drinks.
