Magnesium is a mineral that is essential for many processes in the body, including nerve function, muscle contraction, and bone development.
It is found naturally in many foods, such as leafy green vegetables, whole grains, nuts, and seeds.
Magnesium has been linked to various health benefits, including a reduced risk of heart disease, type 2 diabetes, and migraine headaches. It may also play a role in brain health.
A recent study at Australian National University has found that people who consume more magnesium in their diet may have healthier brains as they age.
The study, conducted by Khawlah Alateeq et al and published in the journal BMC Medicine, looked at the relationship between dietary magnesium intake and brain health in middle-aged and older adults.
The study used data from the UK Biobank, which includes health information from over 500,000 people across the UK.
The researchers analyzed data from over 6,000 participants between the ages of 40 and 73.
They looked at the participants’ dietary magnesium intake, brain volumes, and white matter lesions (WMLs), which are changes in the brain that are associated with aging and cognitive decline.
The researchers found that participants who had higher levels of magnesium in their diet had larger brain volumes than those who consumed less magnesium.
Specifically, higher levels of magnesium intake were associated with larger gray matter volumes and larger hippocampal volumes, which are important for memory and learning.
The study also found that magnesium intake was particularly important for women’s brain health.
Women who had higher levels of magnesium in their diet had larger brain volumes than women who consumed less magnesium.
Additionally, women who had decreasing levels of magnesium intake over time had smaller brain volumes and larger white matter lesions than women who had stable magnesium intake.
The study’s findings suggest that consuming more magnesium in the diet may be beneficial for brain health, particularly as people age.
Foods that are high in magnesium include leafy green vegetables, nuts, seeds, and whole grains.
The researchers note that further research is needed to confirm their findings and to explore the potential mechanisms behind the relationship between magnesium intake and brain health.
However, their study adds to a growing body of evidence suggesting that a healthy diet is important for both physical and cognitive health.
For middle-aged and older people, there are several ways to protect brain health:
Eat a healthy diet: Consuming a diet rich in fruits, vegetables, whole grains, lean protein, and healthy fats can help support brain health. In particular, foods high in omega-3 fatty acids, such as fish and nuts, have been linked to better cognitive function.
Exercise regularly: Regular exercise has been shown to improve brain function and protect against cognitive decline. Aim for at least 150 minutes of moderate-intensity exercise per week.
Get enough sleep: Lack of sleep can have negative effects on cognitive function and memory. Aim for 7-8 hours of sleep per night.
Manage stress: Chronic stress can damage brain cells and impair cognitive function. Finding healthy ways to manage stress, such as exercise, meditation, or spending time in nature, can help protect brain health.
Stay socially active: Maintaining social connections and engaging in social activities has been linked to better cognitive function and a reduced risk of cognitive decline.
Challenge your brain: Engage in mentally stimulating activities, such as reading, puzzles, or learning a new skill, to help keep your brain active and healthy.
Avoid smoking and excessive alcohol consumption: Both smoking and excessive alcohol consumption have been linked to cognitive decline and an increased risk of dementia. Avoiding these behaviors can help protect brain health.
If you care about brain health, please read studies about how the Mediterranean diet could protect your brain health, and blueberry supplements may prevent cognitive decline.
