Splenda Could Destroy Algae's Ability to Eat CO2 PDF Print E-mail

People who want to avoid genetically engineered sugar this year should think twice about one of the alternatives. Sucralose, or Splenda, is reportedly pervasive in Norway and Sweden's wastewater, leaving some scientists worried about the sugar-like substance's effect on the environment.

Data shows that Splenda is excreted by humans nearly 100 percent unchanged, and can persist in the environment for years. Some scientists say the substance could change organisms' feeding behaviors and interfere with plant photosynthesis. They report, for example, that it could possibly shut down CO2 uptake in algae.

Splenda was approved in the 1990s for human consumption in Canada and the US, followed by EU countries. None of these countries thought it necessary to conduct an environmental impact assessment since the chemical wasn't considered toxic in any way.

Now, as questions about the unintended consequences of the chemical's persistence in the environment mount, testing for such impacts may be tricky. As one scientist reported, testing methods for potential impacts of a sugar-like substance on ecosystems don't exist.

Sweden has started discussions with the EU about other food additives on the market that may warrant environmental review, citing the lack of inquiry into potential impacts of these substances on the environment.

Interesting. It seems like it would be a fairly simple matter to subject algae to Splenda in a lab and observe the effects.

i hate splenda because it doesn't taste right and i don't see anything wrong with the yummy cane sugar i get ... BUT i wont believe there is anything ells wrong with it until i see a study to prove it... just because someone thinks it and says is and puts it on paper doesn't make it true... give me proof

Citation Needed!
I'm assuming you made this up and I'm giving you a stumbleupon thumbs down!
Photosynthesis is a well known reaction, If you think sucralose can interfere with it, show me how.

Here's the citation you were probably looking for.

Amazing that we continue to come up with new chemicals and start using them with very little testing of their long term effects in the environment.

Responsible Sewage Disposal
written by Uncle B, December 01, 2009
Norway bio-gasses sewage and runs city busses on the gas! The question is:"Does Splenda hurt, in any way the responsible disposal of sewage?" Does Splenda show up in the fertilizer sludges so desperately needed? Does Splenda show up in the effluents from responsible sewage treatment? Can we ban Splenda save for diabetic use - by perscription? Is Splenda a necessity for life or a passing dietary fad? Splenda upsets my digestion and gives me gas! Is it really more healthy than sugar? Can wieght loss be achieved in environmentally safe ways? Does Splenda affect dry composting of humanure? What types of Algae are affected? is this environmentally significant or a moot point? Are smaller organisms like fish affected? More on this fascinating subject, Please!

Sugar is an informal term for class of edible crystalline substances, mainly sucrose, lactose, and fructose.They have characteristically a sweet flavor. In food, sugar almost exclusively refers to sucrose, which primarily comes from sugar cane and sugar beet. Excessive consumption of sucrose has been associated with increased incidences of type 2 diabetes, obesity and tooth decay.Sugar consumption varies by country depending on the cultural traditions. Brazil has the highest per capita production and India has the highest per-country consumption.

Are you an Envirovore?

It's true what our moms said...we are what we eat. In fact, it's truer than they thought. What I eat doesn't just affect me anymore, it affects all of us.

Unfortunately, the story of food can sometimes be complicated. But envirovores help each other out...which is why this blog will be bringing you news, tips, and information about food and the environment every step of the way.
