Dementia is an incurable, debilitating illness that impacts millions of persons worldwide. Though science continues to search for answers to treat the illness, there has been a shift toward prevention. The study supplied new proof for a hyperlink among magnesium intake and brain wellness.

Earlier research have shown that dietary magnesium intake is involved in biological processes related with brain aging and could enable avert neurodegeneration that at some point leads to dementia.

The precise mechanisms underlying magnesium’s neuroprotective effects have not been clearly identified, specifically at what point magnesium intake starts to influence brain wellness. Simply because life-style and diet plan are modifiable danger variables for dementia, it is essential to know much more about the function of magnesium as a preventative agent.

A new study by researchers at the Australian National University looked at brain volume and white matter lesions (WML) and their association with dietary magnesium. They also examined the connection among blood stress and magnesium and regardless of whether there have been variations in these relationships among males and ladies.

Brain volume is an essential element to think about for the reason that brain shrinkage (atrophy) in persons diagnosed with Alzheimer’s illness precedes the onset of clinical symptoms. Atrophy of the hippocampus, a complicated brain structure that plays a function in finding out and memory, is an early function of Alzheimer’s illness.

White matter is identified all through the central nervous method, but mainly in the interior of the brain. It consists of bundles of millions of nerve fibers that connect to the gray matter of the brain. VMLs are abnormalities that seem as vibrant spots on an MRI scan of the brain. They could reflect standard aging and have no clinical significance, or they could indicate inflammation and harm to myelin, the insulating sheath about nerves. VMLs are believed to be an early sign of neurodegenerative circumstances such as Alzheimer’s illness and stroke.

The existing study integrated six,001 participants drawn from the UK Biobank. The participants, aged among 40 and 73, had no proof of neurological issues. Participants have been asked to comprehensive an on the internet questionnaire 5 instances more than 16 months, and their responses have been utilised to calculate their everyday magnesium intake primarily based on 200 foods of varying portion sizes.

Researchers have identified for the initially time that dietary magnesium is related with higher brain volume and reduced VML, specifically in gray and white matter. They identified that the neuroprotective impact of magnesium was substantial but varied in distinctive brain regions, specifically powerful for the gray matter and hippocampus.

Compared to an individual with a standard magnesium intake of about .1 oz (350 mg) per day, these who consumed much more than 550 mg of magnesium per day had a brain age about a year younger than their “physique age” by the time they reached 55.

“Our study shows that a 41% raise in magnesium intake could lead to significantly less age-connected brain shrinkage, which is related with much better cognitive function and a reduced danger or delayed onset of dementia in later life,” stated Khavlah Alateek, lead author of the study. .

Though the information showed a powerful association among dietary magnesium and brain volume and VML in each males and ladies, the doable neuroprotective effects of magnesium reached significance only in ladies. The impact was stronger in postmenopausal ladies than in premenopausal ladies, but the researchers point out that this could be due to magnesium’s anti-inflammatory properties. Unexpectedly, the study identified no association among dietary magnesium intake and blood stress.

Primarily based on the outcomes of their study, the researchers suggest escalating magnesium intake from a young age to defend against neurodegenerative illnesses.

“The study shows that larger dietary magnesium intake could contribute to neuroprotection earlier in the aging approach, and the preventive effects could commence in our 40s or even earlier,” Alateek stated. “This suggests persons of all ages ought to spend much more focus to their magnesium intake.”

So it appears like bananas, green leafy vegetables, avocados, cashews and almonds, legumes, tofu, fatty fish, seeds and complete grains are on the menu. But do not neglect dessert: dark chocolate is also really wealthy in magnesium.

The researchers hope that their findings will produce additional investigation on the advantages of magnesium on brain wellness and will be utilised to guide public wellness methods aimed at prevention.

“Our investigation could inform the improvement of public wellness interventions aimed at advertising wholesome brain aging by means of dietary methods,” stated Erin Walsh, co-author of the study.

The study was published in European Journal of Nutrition.
