More magnesium in our daily diet leads to better brain health as we age, according to scientists from the Neuroimaging and Brain Lab at The Australian National University (ANU).
The researchers say increased intake of magnesium-rich foods such as spinach and nuts could also help reduce the risk of dementia, which is the second leading cause of death in Australia and the seventh biggest killer globally.
The study of more than 6,000 cognitively healthy participants in the United Kingdom aged 40 to 73 found people who consume more than 550 milligrams of magnesium each day have a brain age that is approximately one year younger by the time they reach 55 compared with someone with a normal magnesium intake of about 350 milligrams a day.
“Our study shows a 41 per cent increase in magnesium intake could lead to less age-related brain shrinkage, which is associated with better cognitive function and lower risk or delayed onset of dementia in later life,” lead author and PhD researcher Khawlah Alateeq, from the ANU National Centre for Epidemiology and Population Health, said.
“This research highlights the potential benefits of a diet high in magnesium and the role it plays in promoting good brain health.”
It’s believed the number of people worldwide who will be diagnosed with dementia is expected to more than double from 57.4 million in 2019 to 152.8 million in 2050, placing a greater strain on health and social services and the global economy.

That is great news! Thank you, Tony! I:m going to add spinach more often to a daily diet and boost the nutrients. It reminds me of the Popeye character who transformed into action after eating his spinach! Cheers!
