Hi Guys
I am on a mission to help you understand what is in your food is causing us and our children's health issues and we need to become educated.
Fraser my son announced he is going to Uni to study food technology and Nutrition. We went to the open day and were shown into a chemistry lab where I felt quite at home. Instead of making pharmaceuticals which is my background this lab investigated making food additives and emulsifiers. In the demo, they showed us how bubble tea is made. Well that doesn't occur naturally in nature. Tasty and sweet but those little bubbles are not naturally occurring so are chemically produced.
Good news is that the food technologists of the future will be trying to replace the risky chemicals they got away with in the past with more natural alternatives. However that's in the future so we have to still put up with aspartame and the emulsifiers that are not banned yet but animal studies are coming thick and fast that these chemicals disturb our microbiome, those trillions of bacteria that are the workings of our bodies extracting important vitamins that work our genes and stimulate immune cells. Disturb those workers and we are in trouble.
I have a lovely Podcast from ZOE to help you understand. Here are some extracts from that Podcast to summarise.
In the UK, as of last year, emulsifiers are present in more than half of all ultra-processed foods, including 95% of pastries, buns and cakes, ice creams and yogurts, and almost 80% of confectionery.
So let's say you've picked up a sandwich. The filling might contain an emulsifier called guar gum. A sandwich spread could have something called xanthan gum in it. Or you might pop some cereal in your basket and that might have stearoyl lactylates. Even the bar of chocolate you threw in at the till, that likely contains lecithin.
Some of these are more risky than others but it's a cocktail that builds up like glue in our systems that is the real issue.
One study really looked at the intake of some additives, including emulsifiers, in the U.K., France, and Ireland. And it found that children and adults did actually exceed what's called the acceptable daily intake of some emulsifiers.
Are these emulsifiers bad for us? most of the research we have on emulsifiers to date on the mechanism in which they work did come from animal studies.
They appear to cause an imbalance in the gut microbes, and this promotes metabolic syndrome and inflammation.
Another mouse study concluded that the emulsifier carboxymethyl cellulose, which is often seen as CMC on food packaging, and is really ubiquitous, is an ideal suspect to account for the rise of irritable bowel syndrome in the 20th century.
In 2017, there was a small randomized control trial in humans looking at the effect of emulsifier carrageenan, in this case, on patients who have ulcerative colitis, which is a type of irritable bowel disease. And it concluded that carrageenan intake increases the likelihood of ulcerative colitis relapse, which is really quite serious.
Emulsifiers are not a natural part of our diet, they're not something that you can make in the kitchen. It's therefore not something that we've ever sort of evolved to be exposed to in the sort of scale that we're seeing. And yet they're in most foods in the U.S and the UK. now, and an ever-increasing fraction of foods in the rest of the world.
So reducing your intake of ultra-processed foods generally will lead to cutting down on your intake of emulsifiers, as well as other additives, and make space for food that is better for you.
Get the Yuka APP and get scanning identify what's in your house and let's get back to the kitchen and start teaching our kids to cook.
