Litium i dricksvattnet

År 1817 upptäckte den svenske kemisten Johan August Arfwedson grundämnet litium, en metall som har visat sig effektiv mot bipolär sjukdom. Nu visar en ny studie, ”Lithium Levels in Drinking Water and Risk of Suicide”, publicerad i British Journal of Psychiatry, att tillsatser av litium i dricksvattnet har effekt på självmordsfrekvensen i populationen:

Although lithium is known to prevent suicide in people with mood disorders, it is uncertain whether lithium in drinking water could also help lower the risk in the general population. To investigate this, we examined lithium levels in tap water in the 18 municipalities of Oita prefecture in Japan in relation to the suicide standardised mortality ratio (SMR) in each municipality. We found that lithium levels were significantly and negatively associated with SMR averages for 2002–2006. These findings suggest that even very low levels of lithium in drinking water may play a role in reducing suicide risk within the general population.

Vill man förbättra tandhälsan tillsätter man fluor; vill man förbättra det mentala välmåendet tillsätter man litium. Varför inte lägga till lite oxytocin och oxerin A medan man ändå håller på?
