Fluorstoffer og hjerneskade

Lars Rasborg

(See the English translation of this newsletter below the Danish newsletter)

Regeringen har besluttet at indføre forbud mod en række fluorstoffer i pesticider, der anvendes i landbruget. For det fleste midlers vedkommende træder forbudet i kraft i slutningen af 2026, så det bliver først i 2027 at landbrugsafgrøder i Danmark skal dyrkes uden disse pesticider. Det er dog ikke alle fluorstoffer, der forbydes, og fødevarer fra andre lande kan fortsat være behandlet med fluorstoffer. Derfor må man stadig vælge økologiske fødevarer for at undgå disse fluorstoffer. PFAS er en gruppe fluorstoffer, der kan trænge gennem blod-hjerne barrieren og ophobes i hjernen. PFAS er forbundet med ADHD, Parkinsons og Alzheimers sygdom. Det er derfor et skridt i den rigtige retning, at nogle af disse stoffer udfases.

Pesticider er dog langtfra den eneste kilde til skadelige fluorstoffer. Der er stadig mange, der bruger tandpasta med fluor, typisk i form af natriumfluorid. Dette er en anden type fluorforbindelse, end den man finder i pesticider, men den er stadig skadelig. Forskning har vist, at den kan give fosterskader og reducerer intelligensen.

Selvom man spytter tandpastaen ud, så kan fluor stadig optages gennem mundens slimhinder. Tandpastaen skader ikke kun brugeren, men forurener også vandmiljøet, når den ledes med spildevandet ud i havet. Der er heldigvis mange tandpastaer uden fluor på markedet. De sælges især i helsebutikker.

Der er meget man kan gøre for at undgå huller i tænderne i stedet for at anvende den giftige fluor. Især kan det anbefales at undgå stærke syrer på tænderne. Cola er særligt slem. Juice bør blandes med vand for at gøre den mindre syrlig. Se pH-værdien for forskellige almindelige drikkevarer her: Acidity (pH) of Common Drinks

En del medikamenter indeholder også fluorstoffer. Det gælder bl.a. antidepressiv medicin. Som beskrevet i et tidligere nyhedsbrev, så øger antidepressiv medicin risikoen for demens: Antidepressiv medicin fremmer demens. Desuden er antidepressiv medicin katastrofalt ineffektiv til behandling af depression, og der findes bedre alternativer som beskrevet i dette nyhedsbrev: Svindel med forsøg med antidepressiv medicin. Det er ikke kun skidt for brugerne af denne medicin. Rester og nedbrydningsprodukter ledes med spildevand ud i havet. I indre farvande som Østersøen er koncentrationen af medicinrester efterhånden blevet så stor, at det påvirker fiskene i havet.

Teflon, der anvendes som belægning i “non stick” køkkengrej, er også et skadeligt fluorstof. Det blev opfundet af kemivirksomheden Dupont i 1938. Fødevarer, der kommer i kontakt med teflon, kan blive forurenet med dette fluorstof. Det må derfor anbefales at undgå køkkengrej (f.eks. stegepander) med teflonbelægning.

Fluorine compounds and braindamage

The Danish government has decided to ban the use of a number of fluorine containing pesticides used in agriculture. For most of those pesticides the ban will go into effect towards the end of 2026, so it will not be until 2027, that crops in Denmark have to be grown without those pesticides. However, not all fluorine containing pesticides will be banned, and crops from other countries may still be treated with fluorine containing chemicals. Therefore you still have to choose organic food to avoid those chemicals. PFAS is a group of fluorine compounds, that can penetrate the blood-brain barrier and accumulate in the brain. PFAS is linked to ADHD, Parkinson’s and Alzheimer’s disease. It is therefore a step in the right direction that some of those chemicals are taken out of use.

However, there are many other types of harmful fluorine compounds. There are still many people, who use toothpaste with fluoride, typically in the form of sodiumfluoride. This is another type of fluorine compound than the one found in pesticides, but it is still harmful. Research has shown that it may cause embryo damage and reduce intelligence.

Even though you spit out the toothpaste, some of it can still be absorbed through the mucous membranes in the mouth. The toothpaste does not only harm the user, but it also contaminates the waterways and the sea when it is discharged with the wastewater. Fortunately there are many types of toothpaste without fluoride on the market. They are mainly found in health food shops.

You can do many things to prevent cavities instead of using toxic fluoride. One recommendation is to avoid strong acids on the teeth. Cola is particularly harmful. Juice should be mixed with water to reduce the acidity. You can see the pH-value for various common drinks here: Acidity (pH) of Common Drinks

Several types of medication also contain fluorine. One such type is antidepressant medication (SSRI medication). As described in an earlier newsletter, antidepressant medication increases the risk of dementia: Antidepressant medication promotes dementia. It is also horribly ineffective for treating depression, and there are better alternatives as described in this newsletter: Fraudulent trial of antidepressant medication.

It is not only bad for the users of such medication. Residues and metabolites are discharged with the wastewater into the sea. In inner waters such as the Baltic Sea, the amount of medical residues has become so big, that it affects the fish living there.

Teflon, which is used as coating in non stick cookware, is also a harmful fluorine compound. It was invented by the chemical corporation Dupont in 1938. Foods, that come into contact with teflon, may be contaminated with this chemical. It is therefore recommended to avoid cookware such as frying pans with teflon coating.
