Increasing Magnesium Intake may Delay Brain Aging

A study , which involved over 6,000 cognitively healthy participants aged 40 to 73 in the United Kingdom, found that consuming more than 550 milligrams of magnesium each day can lead to a brain age that is approximately one year younger by the time individuals reach 55, compared to those with a normal magnesium intake of about 350 milligrams a day.

Lead author and Ph.D. researcher Khawlah Alateeq from the ANU National Centre for Epidemiology and Population Health stated that a 41% increase in magnesium intake could result in less age-related brain shrinkage, which is associated with better cognitive function and lower risk or delayed onset of dementia in later life.

The study highlights the potential benefits of a diet high in magnesium and its role in promoting good brain health. In addition, the researchers believe that a higher intake of magnesium in our diets from a younger age may safeguard against neurodegenerative diseases and cognitive decline by the time we reach our 40s. The study suggests that individuals of all ages should pay closer attention to their magnesium intake.

Magnesium-rich foods such as leafy green vegetables, legumes, nuts, seeds, and whole grains are recommended to increase daily magnesium intake. The findings could inform the development of public health interventions aimed at promoting healthy brain aging through dietary strategies. The study also notes that as the number of people worldwide diagnosed with dementia is expected to more than double by 2050, greater attention should be directed towards prevention, including a focus on diet.
