New research suggests that consuming more foods rich in magnesium could improve brain health, particularly in women. The study, published in the European Journal of Nutrition, involved over 6,000 adults aged 40 to 73 in the UK. Participants completed an online survey multiple times over 16 months, which allowed researchers to calculate their average daily magnesium intake based on their consumption of various magnesium-rich foods such as leafy greens, legumes, seeds, nuts, and whole grains. MRI imaging was used to measure participants' brain volumes. The findings revealed that individuals who consumed more than 550 milligrams of magnesium per day had larger brain volumes, equivalent to a brain age approximately one year younger by the age of 55, compared to those who consumed about 350 milligrams of magnesium daily. These effects were more pronounced in women compared to men. The researchers noted that less age-related brain shrinkage is associated with better brain function and a reduced risk of dementia in the future
