Artificial sweeteners are typically off the list of foods recommended by holistic nutritionists for many reasons. Historically these have largely been to do with neurological, metabolic or carcinogenic concerns.
Here’s a new mouse study on Sucralose (trade names Splenda, Zerocal, Sukrana, SucraPlus, Candys, Cukren, Nevella) which says that it probably does cause or contribute to tumour growth. As we have been learning in recent years, gut bacteria in the human microbiome are instrumental in protecting us from pathogens, including carcinogens.
We’re also finding that artificial sweeteners are causing glucose intolerance – meaning they likely play a role in actually causing Type 2 Diabetes. This is due to their role in altering the gut microbiome. In a troubling irony, artificial sweeteners remain in the dietary recommendations of the Canadian Diabetes Association, declared safe by Health Canada.
Which is one of the problems with the speed of knowledge advancement in science. We’ve only been aware of the importance of the human microbiome for a matter of years, not even decades, so it’s no surprise that public health policy can’t keep up.
But it’s not just our health we’re risking. Some of these sweeteners pass through the human digestive system – which is one way they don’t affect our blood sugar – and end up in our water systems, through the wastewater treatment system, which doesn’t screen them out. This means they’ll also end up in soil and groundwater.
So really. If these synthetic substances are probable carcinogens, cause glucose intolerance, and are harmful to our own gut bacteria, it seems pretty irresponsible to be sharing them with the wild aquatic and bacterial populations in our environments. A failure of holistic thinking, as usual, at work here, as we also don’t know to what extent these substances will work their way through the food chain, or what effects there may be upon the ecosystems affected.
The only viable alternative to artificial sweeteners, so far, is stevia extract, but even here there are cautions. Avoid highly processed, flavoured or alcohol-based versions: go for the purest version you can find. You may even wish to grow it yourself, and dry and grind the leaves.
