A laboratory test reveals that all analyzed soda cans, with brands such as Coca Cola or Pepsi, contain hormonal contaminants. Yet another reason to discourage the consumption of this type of beverage.
The inner lining of the cans releases small amounts of toxins that interrupt the functioning of the hormonal system, without any label reporting their presence.
We know that soft drinks are not a healthy alternative to quench thirst due to their high sugar content. But now a laboratory test adds another reason, less known, to avoid this type of drink: the coating of the cans releases toxins to the content, which add to the cocktail of substances that, daily, alter the correct functioning of the hormonal system.
Lab test results
The Danish Consumer Council THINK Chemicals, author of the study, classifies each product into three categories according to its toxic content: the green label means that the product is not dangerous, the yellow label implies that it has some hormonal toxin and the red label means that it is not recommended for use. consumption for its content of hormonal pollutants. The results of this study are as follows:
- 8 of the 14 cans analyzed obtain the RED label: 7 of them for containing Bisphenol-A and the other for containing Bisphenol-F, both endocrine disruptors.
- The remaining 6 cans get the YELLOW label because they contain the substance called BADGE (diglycidyl ether of bisphenol-A), a substance that, by the way, appears in all the cans analyzed.
The amounts found of Bisphenol-A, the best known of these toxins, vary between 1.7 and 3.5 micrograms per can. The Bisphenol-F content found was 1.6 micrograms per can. These amounts are within legal limits, excessively high according to the Technical University of Denmark.
The danger of the "cocktail effect"
A can of soda, by itself, is not a problem. But scientists worry about the so-called"Cocktail effect", that is, the combined effect of exposure to various toxins found in a wide variety of sources (food, water, household products, cosmetics, etc ...).
No experiment can assess the synergistic effect (the effect of the mixture is greater than the sum of the effects of each individual toxicant) of joint exposure to such a large and varied mixture of toxicants.
Bisphenol A, Bisphenol F and BADGE
After years of struggle, today it is recognized that Bisphenol A is a dangerous poison due to its effects on the endocrine system. Studies link it to breast cancer, damage to human reproduction and the immune system.
Bisphenol-A or BPA was created in the middle of the last century as a synthetic hormone for pharmaceutical purposes, but the disastrous laboratory results advised against its commercialization. Despite the serious effects that they detected then, it was marketed as a raw material for products for daily use and in contact with food, such as polycarbonate for baby bottles or the coating of tin cans.
It is currently included in the REACH candidate list for being toxic for reproduction and, in February, France will request its inclusion in the same list for endocrine disruptor.
Less is known about Bisphenol-F and BADGE, but the latest research shows that they can also have endocrine disrupting effects, like Bisphenol-A.
The presence of endocrine disruptors in soft drink cans has prompted the Danish Food Safety Agency to advise both pregnant women and children to avoid products in this type of packaging.
What to do?
The solution against hormonal pollutants is political.
This February, European states will decide whether to ban endocrine disruptors in pesticides, which would result in their prohibition in other uses, such as food packaging. It is essential that Spain maintain its position against these toxins.
Here you can add your signature to those of others and other Europeans, against hormonal pollutants.
