The Gut-Brain Axis
In the evolving landscape of healthcare, the relationship between our gut health and mental well-being—colloquially known as the “gut-brain axis”—is rapidly garnering attention. Researchers are uncovering a fascinating web of communication between the billions of bacteria residing in our gut (collectively termed the “gut microbiota”) and our brain. This bidirectional relationship suggests that what we eat may profoundly impact not only our physical health, but our mental health as well.
Understanding the Gut-Brain AxisIn simple terms, the gut-brain axis refers to the complex communication network that exists between the central nervous system (the brain and spinal cord) and the enteric nervous system (the “mini-brain” in our gut). This connection ensures the proper functioning of digestive processes, immune responses, and even emotional regulation. The role of the gut microbiota in this process cannot be overstated. These trillions of microorganisms, including bacteria, viruses, and fungi, influence the gut-brain axis through various mechanisms, such as influencing the body’s immune response, producing neuroactive substances, and directly interacting with nerve cells in the gut.
Nutrition and Mental Health
Dietary patterns can significantly influence the composition of the gut microbiota. A diet rich in fruits, vegetables, whole grains, and lean proteins, for example, supports a diverse microbiota linked to positive health outcomes. On the contrary, diets high in processed foods, saturated fats, and sugars can disrupt the gut microbiota, contributing to “dysbiosis,” an imbalance associated with various health issues, including mental health disorders.
Research shows a potential link between gut dysbiosis and mental health disorders such as anxiety, depression, and autism spectrum disorder. Although the precise mechanisms are not fully understood, evidence suggests that alterations in the gut microbiota may influence mood and behaviour through the gut-brain axis.
Promoting Gut and Mental Health Through Nutrition
Given the potential influence of diet on the gut microbiota and, subsequently, mental health, promoting a balanced, nutritious diet could be a strategic approach to bolster mental well-being.
Emphasizing a diet rich in prebiotic and probiotic foods is one approach. Prebiotics, found in foods like onions, garlic, and bananas, provide nourishment for beneficial gut bacteria. Probiotics, present in fermented foods like yogurt, kefir, and sauerkraut, directly contribute beneficial bacteria to our gut. However, it’s not only about adding beneficial foods to our diets; reducing intake of foods that can harm our gut microbiota, like highly processed foods or those high in saturated fat and sugar, is equally crucial.
Looking Forward
As our understanding of the gut-brain axis deepens, it’s becoming evident that a paradigm shift in healthcare may be on the horizon—one where diet and nutrition could play a central role in managing mental health. Still, it is important to remember that while nutrition is a powerful tool, it is not a cure-all. Comprehensive mental healthcare should be a holistic endeavour, incorporating psychological, social, and biological aspects.
In the meantime, as researchers continue to unravel the complexities of the gut-brain axis, individuals can still reap the benefits of a healthy, balanced diet on both gut and mental health. After all, as the old adage goes, we truly might be what we eat.

Traumatic Brain Injuries
Traumatic Brain Injury (TBI) remains a crucial issue affecting millions of people worldwide each year. With an annual incidence rate of approximately 500 out of every 100,000 individuals, this translates into an estimated 165,000 new TBI cases in Canada alone each year. While the scale of the problem is staggering, the impacts and the available treatments for TBI are also areas that warrant extensive exploration. TBI is a complex injury with a broad spectrum of symptoms and disabilities. It often results from a violent blow or jolt to the head or body. An object penetrating the skull, such as a bullet or shattered piece of skull, can also cause TBI. The severity of these injuries can range from a brief change in mental status to an extended period of unconsciousness or amnesia after the injury.
The Impact of TBI
The consequences of TBI are immense and can affect all aspects of an individual’s life, including physical and mental health, family life, employment, and social relationships. It is a leading cause of death and disability among young adults, and survivors often face lasting challenges, including physical impairment, cognitive deficits, emotional and behavioral changes.
Physical impairments after a TBI may include weakness, coordination issues, difficulty speaking, hearing loss, or vision problems. Cognitive deficits can affect memory, attention, information processing speed, and executive functions that allow for planning and organization. Emotional and behavioral changes can include depression, anxiety, aggression, impulse control problems, and personality changes. These changes can create significant challenges in social interactions, both within the family and in broader social contexts.
Side Effects of TBI
The side effects of TBI can be life-altering and may continue long after the initial injury. These may include sleep disorders, mental health issues like depression and anxiety, alcohol or substance abuse, and other health issues such as seizures. Post-traumatic headache is the most common side effect of TBI, and other chronic pains are also common.
Treatments for TBI
The treatment for TBI is multifaceted and depends on the severity of the injury. For mild cases, rest and medication to relieve headache might be enough. However, more severe cases may require emergency care to ensure the person has enough oxygen, maintains adequate blood flow, and controls blood pressure. Surgery may be required to minimize additional damage to brain tissues. This might involve repairing skull fractures, bleeding, or removing clotted blood. After the initial treatment, rehabilitative care will help the individual regain daily functional ability, which may include physical therapy, occupational therapy, speech and language therapy, and psychological support.

Brain Tumour Awareness
The human brain, with its intricate networks and innumerable connections, is an organ of staggering complexity. It is the command centre of our bodies, responsible for our thoughts, emotions, memory, and the essential functioning of all other organs. But like all parts of the body, it can also be affected by disease – including brain tumours. Recognizing May as Brain Tumour Awareness Month, this article seeks to raise awareness about this serious health issue, its types, symptoms, treatments, and the importance of research and support for those living with brain tumours.
What is a Brain Tumour?
A brain tumour is a mass or growth of abnormal cells in the brain. There are many types of brain tumours. Some are benign, meaning they are non-cancerous and do not spread. Others are malignant, or cancerous, and can invade nearby tissues and spread to other parts of the body. Brain tumours can start in the brain (primary brain tumours), or they can begin in other parts of the body and spread to the brain (metastatic or secondary brain tumours).
Symptoms of Brain Tumours
The symptoms of a brain tumour can vary greatly, depending largely on the tumour’s size, type, and location. Common symptoms may include new or changed pattern of headaches, unexplained nausea or vomiting, vision problems, loss of balance, speech difficulties, and seizures. In some cases, there may be no symptoms until the tumour has become quite large.
It’s important to note that these symptoms can also be caused by conditions other than brain tumours. However, anyone experiencing such symptoms should consult a healthcare professional for evaluation.
Diagnosis and Treatment
A neurologist typically diagnoses brain tumours using a combination of neurological examination, imaging tests such as MRI or CT scans, and sometimes biopsy.
Treatment for a brain tumour depends on its type, size, and location within the brain, as well as the patient’s age and overall health. Options may include surgery, radiation therapy, chemotherapy, targeted therapies, or a combination of these. In some cases, when the tumour is slow-growing and not causing symptoms, watchful waiting may be recommended.
Awareness and Research
Despite advances in medical science, brain tumours remain a challenging condition to diagnose and treat. They can affect people of all ages, genders, and ethnicities, and their impact can be profound – causing physical, cognitive, and emotional changes that can significantly affect quality of life.
Raising awareness about brain tumours is crucial to improving outcomes for those affected. Greater awareness can lead to earlier diagnosis, access to better treatments, and more funding for research.
Research is the key to unlocking new treatments and, ultimately, a cure for brain tumours. It spans a wide range, from studying the genetics of brain tumours to developing and testing new drugs and improving surgical techniques. Clinical trials are a critical part of this research process, offering patients access to the latest experimental treatments and contributing to the broader understanding of brain tumours.
Supporting Those Affected
Living with a brain tumour can be a daunting experience, often accompanied by fear and uncertainty. People with brain tumours and their families need extensive support. This can include information and resources to understand and manage the disease, psychological and emotional support, help with coordinating care and navigating the healthcare system, and opportunities to connect with others in similar circumstances.
There are numerous organizations and support groups, both online and offline, that offer help. These can be invaluable sources of support and understanding.

A New Hope for Alzheimer’s Patients
Alzheimer’s disease is a debilitating neurodegenerative disorder that affects millions of people worldwide. This progressive illness causes memory loss, cognitive decline, and eventually, the inability to perform daily activities. The exact cause of Alzheimer’s is still unknown, but it is believed to involve a combination of genetic, environmental, and lifestyle factors. Researchers have identified two proteins, amyloid and tau, that play a crucial role in the disease’s development. Amyloid proteins clump together to form plaques, while tau proteins form tangles, both of which disrupt communication between brain cells and trigger inflammation, ultimately leading to cell death.
Despite ongoing research efforts, finding an effective treatment for Alzheimer’s has been an uphill battle. However, recent findings from a late-stage trial conducted by Eli Lilly and Co (LLY.N) have brought new hope for Alzheimer’s patients and their families.
Eli Lilly and Co’s experimental drug, Donanemab, has shown promising results in a closely watched late-stage trial involving 1,734 participants. The drug met all goals of the trial, slowing the progression of Alzheimer’s by 35% to 36% compared to a placebo in 1,182 people diagnosed with early-stage disease based on brain scans showing deposits of amyloid protein and intermediate levels of tau protein. The remaining 552 patients in the trial had high levels of tau protein, suggesting a lower likelihood of responding to the treatment. When combining both groups, donanemab demonstrated a 22% slowing of Alzheimer’s progression using a Lilly-developed scale to measure cognition and activities of daily living. The drug also showed a 29% slowing of progression based on a more commonly used scale of dementia progression. According to Maria Carrillo, Chief Science Officer for the Alzheimer’s Association, these findings represent “the strongest phase 3 data for an Alzheimer’s treatment to date.”
The positive results from the Donanemab trial offer hope for the development of a second effective treatment for Alzheimer’s disease. With its robust phase 3 trial data, Donanemab could potentially provide an alternative option for patients and medical professionals seeking more effective treatment options. However, it is important to note that Donanemab is not a cure for Alzheimer’s, but rather a treatment that slows the progression of the disease. Further research and trials are necessary to better understand the drug’s long-term effects, potential side effects, and optimal dosing strategies. If approved, Donanemab could significantly improve the quality of life for Alzheimer’s patients and their families, providing a valuable tool in the ongoing fight against this devastating disease.

Purple Day: A Global Movement for Epilepsy Awareness
Every year, people around the world come together to celebrate Purple Day in support of epilepsy awareness. This global initiative was founded in 2008 by Cassidy Megan, a young girl from Nova Scotia, Canada, who wanted to dispel myths surrounding epilepsy and encourage people to learn more about the condition. Purple Day aims to foster understanding, reduce the stigma associated with epilepsy, and support the millions of individuals affected by it. Epilepsy is a neurological disorder characterized by recurrent seizures, which are sudden, uncontrolled electrical disturbances in the brain. These seizures can manifest in various forms, ranging from brief moments of unconsciousness to convulsions and muscle spasms. Epilepsy affects people of all ages, genders, and ethnicities, and it can be caused by genetic factors, brain injuries, infections, or other underlying medical conditions. Proper diagnosis and treatment are crucial to help manage the symptoms and improve the quality of life for those living with epilepsy. Raising awareness about epilepsy is of vital importance because it is a condition that remains misunderstood by many. Public misconceptions and a lack of knowledge can lead to social isolation, discrimination, and reduced opportunities for people with epilepsy. By educating society and promoting conversations about the disorder, Purple Day aims to create a more inclusive and supportive environment for those affected.
In Canada, it is estimated that around 300,000 people, or approximately 1 in 100 Canadians, live with epilepsy. This makes it one of the most common neurological disorders in the country. Despite its prevalence, funding for epilepsy research and support programs is often limited. Purple Day serves as an opportunity to rally communities, health professionals, and policymakers to recognize the importance of addressing epilepsy and the challenges faced by those living with it.
On Purple Day, individuals and organizations worldwide participate in various activities and events to raise awareness about epilepsy. People are encouraged to wear purple clothing or accessories to show their support, while schools, businesses, and landmarks often light up in purple hues. These collective actions help to create a sense of unity and bring attention to the cause.
Social media platforms also play a significant role in amplifying the message of Purple Day, as participants share their stories, experiences, and educational resources using hashtags like #PurpleDay and #EpilepsyAwareness. These digital campaigns help to spread information, foster empathy, and create a global support network for those affected by epilepsy.

What is Frontotemporal Dementia?
Bruce Willis (Alberto E. Rodriguez/Getty Images) It was recently announced that Hollywood actor Bruce Willis had been diagnosed with frontotemporal dementia (FTD), an uncommon form of dementia. This has brought attention to a condition that is not as widely known as Alzheimer’s, the most common type of dementia. In this article, we will delve into the complexities of frontotemporal disorders, discuss their impact on those affected and their families, and explore the symptoms, diagnosis, and current treatment options.
What is Frontotemporal Dementia?
Frontotemporal dementia is a group of progressive neurological disorders that primarily affect the frontal and temporal lobes of the brain. These areas are responsible for various cognitive functions, including decision-making, behavior, emotion, and language. As the disease progresses, these regions of the brain shrink, leading to a decline in cognitive abilities and, eventually, severe impairment.
FTD is different from other forms of dementia, such as Alzheimer’s, in that it tends to affect younger individuals, typically between the ages of 40 and 65. While FTD is less common than Alzheimer’s, it is a significant cause of dementia in younger people, accounting for an estimated 10-20% of all dementia cases in this age group.
Symptoms of Frontotemporal Dementia
The symptoms of FTD can vary significantly, depending on the areas of the brain affected. They generally fall into three main categories:
- Behavioural variant FTD (bvFTD): The most common form of FTD, bvFTD primarily affects personality, behavior, and emotions. Symptoms may include:
- Disinhibition: Acting impulsively, engaging in inappropriate or risky behaviours, and a lack of social tact.
- Apathy: Loss of interest in activities, withdrawal from social interactions, and reduced emotional responsiveness.
- Compulsive behaviors: Repetitive actions or routines, and fixation on particular topics or activities.
- Changes in eating habits: Overeating or a sudden preference for specific types of food, often sweet.
2. Primary progressive aphasia (PPA): This form of FTD affects language abilities and is divided into two subtypes, semantic variant PPA and nonfluent/agrammatic variant PPA. Symptoms may include:
- Difficulty with speaking, understanding, reading, or writing.
- Loss of word meaning and impaired word recognition.
- Struggling to form grammatically correct sentences or difficulty pronouncing words.
3. Disturbances in motor function: Some people with FTD experience movement-related symptoms, such as muscle stiffness, tremors, or balance problems. This is due to the overlap between FTD and other neurodegenerative conditions, such as motor neuron disease or progressive supranuclear palsy.
Frontotemporal dementia affects the frontal and temporal lobes of the brain, leading to changes in behavior, language, and personality. Diagnosis and Treatment
Diagnosing FTD can be challenging, as its symptoms can overlap with other neurological disorders or psychiatric conditions. A thorough evaluation typically involves medical history, neurological exams, cognitive testing, and brain imaging. There is currently no cure for FTD, but some medications may help manage symptoms, such as antidepressants for mood changes or antipsychotics for agitation. In addition, speech therapy, occupational therapy, and physical therapy may help improve function and quality of life.
The Impact on Families
Frontotemporal dementia not only affects the individual diagnosed but also takes a significant toll on their families. The early onset of the disease means that those affected are often still in the workforce, raising children, or caring for elderly parents. As FTD progresses, caregivers may face unique challenges due to the behavioral and personality changes associated with the disease, as well as the need to provide increasing levels of support for everyday tasks.
Support groups, respite care, and counselling services can help families navigate the challenges of FTD and provide invaluable emotional support. Educating oneself about the disease and connecting with others facing similar situations can help reduce feelings of isolation and stress. It is essential for caregivers to prioritize self-care and seek assistance when needed, as caregiving can be physically and emotionally demanding.
Raising Awareness and Future Research
The recent news about Bruce Willis’ diagnosis has cast a spotlight on frontotemporal dementia, raising awareness about this lesser-known form of dementia. Increased public understanding can lead to earlier diagnosis and better support for those affected and their families. Continued research is also crucial to improving our understanding of the disease and developing more effective treatments. Scientists are always investigating the underlying genetic, cellular, and molecular mechanisms of FTD, as well as exploring potential therapeutic targets; while clinical trials are conducted to evaluate the efficacy of new medications and interventions.

Understanding the Spectrum of Neurodivergence
Neurodiversity is a term that has gained significant attention in recent years, particularly in the realms of mental health and education. At its core, neurodiversity is the recognition and acceptance that human brains function and develop in a variety of ways. It celebrates the idea that cognitive differences are a natural part of human variation rather than deficits or disorders. Neurodivergence refers to individuals whose cognitive functioning deviates from what is considered typical or neurotypical. In this article, we will explore some common types of neurodivergence and discuss their unique features.Autism Spectrum Disorder (ASD)
Autism Spectrum Disorder is a neurodevelopmental condition characterized by differences in social communication, interaction, and restrictive or repetitive behaviors. The term “spectrum” acknowledges that ASD encompasses a wide range of abilities and challenges. People with ASD may experience difficulties in understanding social cues, maintaining eye contact, and recognizing facial expressions. However, they may also have exceptional skills in areas like memory, problem-solving, or attention to detail.
Attention Deficit Hyperactivity Disorder (ADHD)
ADHD is a neurodevelopmental disorder marked by persistent inattention, hyperactivity, and impulsivity. Those with ADHD may struggle with organizing tasks, following instructions, or remaining focused on a single activity. On the other hand, they may exhibit creativity, adaptability, and excel in high-energy environments. ADHD can be managed with behavioral therapy, medication, and environmental adaptations.
Dyslexia
Dyslexia is a specific learning difference that affects an individual’s ability to read, write, and spell. It is not related to intelligence, but rather how the brain processes language. People with dyslexia may have difficulty recognizing words, decoding text, or understanding written language. However, they often possess strong problem-solving skills, creativity, and excel in areas like art or engineering.
Dyscalculia
Dyscalculia is a learning difference that affects an individual’s ability to understand and manipulate numbers. It may manifest as difficulty with arithmetic, grasping mathematical concepts, or estimating quantities. Like dyslexia, dyscalculia is not an indicator of low intelligence. People with dyscalculia may excel in areas unrelated to math, such as communication or visual arts.
Tourette Syndrome
Tourette Syndrome is a neurological condition characterized by involuntary movements or vocalizations called tics. These tics can range from simple (e.g., eye blinking) to complex (e.g., repeating words or phrases). Although Tourette Syndrome may cause social challenges, many individuals with the condition lead fulfilling lives and excel in various fields.
Neurodiversity is an essential concept for understanding the wide array of cognitive differences that make us human. By recognizing and embracing neurodivergence, we can create environments that allow everyone to thrive. Supporting neurodivergent individuals involves providing appropriate resources, accommodations, and understanding to help them achieve their full potential. In doing so, we can foster a more inclusive and compassionate society that values the unique contributions of everyone. To learn more about Neurodiversity, visit www.neurodiversityweek.com.

Brain-Boosting Foods
The human brain is the command center of the body, and it requires a significant amount of energy to function correctly. The brain is responsible for all the physical, mental, and emotional activities that we perform every day. Thus, it is essential to consume foods that help to boost the brain’s energy levels and avoid those that cause it to feel fatigued.
Foods that Boost Brain Energy:Fatty Fish: Fatty fish such as salmon, tuna, and mackerel are excellent sources of omega-3 fatty acids. These fatty acids are essential for brain health and can help improve memory and cognitive function. They also help to reduce inflammation in the brain, which can lead to improved mood and reduced risk of depression.
Berries: Berries, such as blueberries, strawberries, and raspberries, are rich in antioxidants that help to protect the brain from oxidative stress. Oxidative stress can damage brain cells, leading to cognitive decline and memory loss. Berries also contain flavonoids that help to improve cognitive function and protect the brain from age-related decline.
Nuts and Seeds: Nuts and seeds are excellent sources of vitamin E, which is essential for brain health. Vitamin E is an antioxidant that helps to protect the brain from oxidative stress and improve cognitive function. Nuts and seeds are also rich in omega-3 fatty acids, which help to improve memory and cognitive function.
Whole Grains: Whole grains such as brown rice, quinoa, and oatmeal are excellent sources of complex carbohydrates. These carbohydrates provide a steady supply of energy to the brain and help to improve cognitive function. Whole grains also contain B vitamins, which are essential for brain health.
Dark Chocolate: Dark chocolate is rich in flavonoids, which help to improve cognitive function and protect the brain from age-related decline. Dark chocolate also contains caffeine, which can help to improve alertness and concentration.
Foods that Cause Brain Fatigue:Processed Foods: Processed foods such as fast food, frozen meals, and packaged snacks are often high in sugar, salt, and unhealthy fats. These foods provide a quick burst of energy but can lead to a crash later on, leaving the brain feeling fatigued and sluggish.
Sugary Drinks: Sugary drinks such as soda, sports drinks, and energy drinks are often high in sugar and caffeine. While they may provide a quick burst of energy, they can lead to a crash later on, leaving the brain feeling fatigued and dehydrated.
Alcohol: Alcohol is a depressant that can impair cognitive function and lead to fatigue and difficulty concentrating. While small amounts of alcohol may have some health benefits, excessive drinking can be detrimental to brain health.
Fried Foods: Fried foods such as french fries, fried chicken, and onion rings are often high in unhealthy fats and calories. These foods can lead to weight gain and increase the risk of developing conditions such as diabetes and heart disease, which can lead to cognitive decline.
White Bread and Pasta: White bread and pasta are often made from refined grains that are stripped of their nutrients. These foods provide a quick burst of energy but can lead to a crash later on, leaving the brain feeling fatigued and sluggish.

Leafy Greens Linked to Lower Alzheimer’s Risk
A new study has found that people who consume more green leafy vegetables had fewer brain proteins linked to Alzheimer’s disease. In the study, 581 individuals with an average age of 84 at the time of the dietary evaluation agreed to donate their brains upon death for the advancement of dementia research. To assess their food intake, participants completed annual questionnaires regarding the amount of food they consumed across various categories. The study investigated the adherence of individuals to the MIND and Mediterranean diets. Although these diets share similarities, such as the inclusion of vegetables, the Mediterranean diet additionally advises consuming fruits and three or more servings of fish per week. Conversely, the MIND diet emphasizes the consumption of green leafy vegetables such as spinach, kale, and collard greens, as well as other vegetables.
So, which green leafy vegetables are the best for brain health? Here are some top picks:
Spinach: Spinach is a great source of vitamins A and K, as well as folate and iron. It also contains high levels of antioxidants, which can help protect the brain from oxidative stress.Kale: Kale is another nutrient-dense leafy green, with high levels of vitamins A, C, and K, as well as calcium and potassium. It also contains sulforaphane, a compound that has been shown to improve cognitive function in animal studies.
Collard greens: Collard greens are a good source of vitamin K and also contain high levels of calcium and potassium. They are also rich in antioxidants and anti-inflammatory compounds that may help protect the brain.Swiss chard: Swiss chard is high in vitamins A and K, as well as magnesium and potassium. It also contains flavonoids, which have been shown to have cognitive benefits.
Broccoli: While not technically a “leafy” green, broccoli is still a great choice for brain health. It contains high levels of vitamin C and sulforaphane, and has been shown to improve cognitive function in animal studies.
Incorporating more green leafy vegetables into your diet is a simple and delicious way to support brain health. They can also be incorporated into your diet in a variety of ways. For example, try adding spinach to your morning smoothie, sautéing kale with garlic as a side dish, or using collard greens as a wrap for your favourite sandwich fillings. Your brain will thank you for it!

Going Green for Brain Power
Green leafy vegetables such as spinach and kale are not just great for your physical health, but they also have an abundance of brain-healthy nutrients that can help slow cognitive decline. Research suggests that including these plant-based foods in your diet can help improve brain function, memory, and overall cognitive health.
Vitamin K, Lutein, Folate, and Beta Carotene are some of the essential brain-healthy nutrients found in leafy greens like spinach and kale. Let’s take a closer look at each nutrient and how they benefit brain health.
Vitamin KVitamin K is a fat-soluble vitamin that plays a vital role in blood clotting and bone health. However, research shows that it may also have an essential role in brain health. Vitamin K helps to prevent the accumulation of calcium in the brain, which can lead to cognitive decline and dementia. In a study published in the Journal of Nutrition, researchers found that participants who had a higher intake of vitamin K had better verbal episodic memory than those who had a lower intake of the nutrient. Another study published in the Neurology Journal found that individuals with higher vitamin K levels had a slower rate of cognitive decline than those with lower levels.
LuteinLutein is a carotenoid that gives leafy greens their vibrant green color. It is also found in other yellow and orange fruits and vegetables, such as corn, carrots, and sweet potatoes. Lutein helps to protect the eyes from age-related macular degeneration, but it also has benefits for the brain. Studies show that lutein helps to improve cognitive function and memory in older adults. A study published in the Journal of the International Neuropsychological Society found that individuals with higher lutein levels performed better on tests of memory and executive function.
FolateFolate, also known as vitamin B9, is essential for brain development and function. It helps to produce DNA and RNA, which are crucial for the growth and repair of brain cells. Folate also helps to regulate the levels of homocysteine, an amino acid that can damage the brain at high levels. Several studies have found that low folate levels are associated with cognitive decline and an increased risk of dementia. A study published in the Journal of Nutrition, Health, and Aging found that individuals with higher folate levels had better cognitive function than those with lower levels.
Beta CaroteneBeta carotene is another carotenoid found in leafy greens, as well as other fruits and vegetables like carrots and sweet potatoes. It is converted into vitamin A in the body, which is essential for vision, immune function, and skin health. Beta carotene also has antioxidant properties that help to protect the brain from oxidative stress and inflammation. A study published in the Journal of Alzheimer’s Disease found that individuals with mild cognitive impairment who took a beta-carotene supplement had significant improvements in cognitive function compared to those who did not take the supplement.
In addition to these brain-healthy nutrients, leafy greens are also rich in other vitamins and minerals that are essential for overall health and wellbeing.
