The homemade dictionary of ingredients supermarkets keep quiet about
Every time we pick up a processed product, the ingredient list reads like an alchemist's incantation. But someone has decided to decipher it. A systematic compilation effort has gathered the most controversial additives —from sweeteners to preservatives— with data that makes you think twice before filling your cart. Neither the food industry nor governments seem in any hurry to clarify what lies behind each E-number.
Aspartame, saccharin and the myth of "sugar-free"
Aspartame tops the list. This sweetener, found in light drinks and chewing gum, was subjected to a study involving 1,800 rats over eight years. According to some sources, the results pointed to cancer risks. The official version declares it harmless at normal doses, but the controversy persists. Saccharin (E-954) is no better: research links it to bladder cancer at high doses and warns of its danger for pregnant women, as it crosses the placenta. The debate over artificial sweeteners remains open, while the industry keeps adding them to "diet" products.
Fluoride: a rat poison turned toothpaste
One of the most striking findings is fluoride. According to the compiled documentation, this compound is a byproduct of the aluminium industry that was originally sold as an insecticide. A 1930 study, funded by the industry itself, allegedly spread its supposed anti-cavity benefits. However, alternative research indicates that fluoride does not prevent cavities but rather causes dental fluorosis (brittle, discoloured teeth) and precipitates calcium, damaging bone structure. The presence of fluoride in drinking water and toothpastes is one of the most controversial topics.
EDTA and fructose syrup: what the label doesn't show
EDTA (ethylene-diamine-tetraacetate) is a sequestrant used in canned foods and alcoholic beverages. In medicine it is used to remove heavy metals from the body, but what is it doing in a jar of chickpeas? Although authorities consider it safe, it can cause diarrhoea, vomiting and hinder the absorption of minerals such as zinc. Meanwhile, fructose syrup, omnipresent in processed foods, is linked to hypertension and obesity. Most alarming: according to analyses cited, up to 45% of products containing it show traces of mercury, a neurotoxin that damages the kidneys and nervous system.
The dihydrogen monoxide wink
Amid so much alarm, there is no shortage of irony. A recurring online comment reminds us that dihydrogen monoxide (DHMO) —that is, water— is responsible for thousands of deaths a year by inhalation and causes a lethal addiction. A way of saying that, with a bit of rhetoric, any substance can seem dangerous. But the difference lies in the dose: water is essential, while many additives are not. The DHMO joke serves as a reminder that scepticism should also apply to sources of information.
The underlying message is clear: the less processed, the better. Reading labels and avoiding unnecessary additives can be cheaper and healthier. But industry pressure and the lack of regulatory transparency force consumers to do their own research. And that, in a supermarket full of fine print, is no easy task.
