According to a new Australian study, a diet rich in magnesium is associated with less age-related brain shrinkage.

Yes magnesium is recognized for its virtues on our mental well-beingthis essential mineral salt would also be beneficial for our brain organ. Indeed, according to the findings of researchers from the Neuroimaging and Brain Lab from the Australian National University (ANU), a higher daily magnesium intake would improve our brain health as we age. Published in the journal European Journal of Nutrition, their recent study was conducted on over 6,000 cognitively healthy people in the UK, aged 40-73. Participants completed five questionnaires regarding their diets over a 16-month period to calculate their daily dietary intakes of magnesium. Brain scans were then taken and compared.

The results revealed that people who consumed more magnesium maintained a larger brain volume over the long term than those which were limited to the recommended intakes (i.e. 320 mg for women and 400 mg for men). However, with age, and this is normal, our brain atrophies. It can then lose up to 10% of its normal size. ” Our study shows that a 41% increase in magnesium intake might therefore reduce age-related brain shrinkage, which is associated with better cognitive function and lower risk, or later onset , dementia said lead author and researcher Khawlah Alateeq. More concretely, the researchers evaluated that the participants consuming more than 550 mg of magnesium per day had, when they turned 55, a brain age regarding a year younger at their expected biological age. On the other hand, these effects neuroprotectors seem to benefit women more than men, and even more so menopausal women than pre-menopausal women. This is perhaps due to the anti-inflammatory effect of magnesium say the researchers.

However, for the Australian team, it is essential to pay attention to our magnesium consumption, from an early age, by integrating foods rich in this mineral into our usual diet. Among those cited by scientists, we find leafy greens, legumes, nuts, seeds and whole grains. Enough to do a real preventive makeover.
