For meget sukker i kosten kan lede til hjernesvind, indikerer et studie.
En mindre hjerne er også knyttet til problemer i alderdommen, så som demens.
Alle de 249 mennesker i studiet havde blodsukkerniveauer i normalområdet.
Imidlertid havde dem med højere blodsukkerniveauer større sandsynlighed for at have mindre hjernevolumen i nøgleområder som hippoocampus (hukommelse) og amygdala (følelser og kognition).

Shrinkage in both of these areas is also linked to developing Alzheimer's disease or another type of dementia.
Dr Nicolas Cherbuin, the study's first author, said:
"Numerous studies have shown a link between type 2 diabetes and brain shrinkage and dementia, but we haven't known much about whether people with blood sugar on the high end of normal experience these same effects."The researchers controlled for other factors that might have affected the relationship including smoking, high blood pressure and alcohol use.

Dr Cherbuin said:
"These findings suggest that even for people who do not have diabetes, blood sugar levels could have an impact on brain health.
More research is needed, but these findings may lead us to re-evaluate the concept of normal blood sugar levels and the definition of diabetes."
