Clear brain fog and improve cognitive function with beta glucans and by incorporating these top brain-boosting foods into your diet.
Omega-3 fatty acids have incredible anti-inflammatory properties, which can help reduce brain fog.
Omega-3 fatty acids are essential fats our bodies need but can't produce on their own.
This means we need to obtain them through our diet.
They’re essential for building brain and nerve cells and play a crucial role in improving learning and memory. (1)
Fatty fish like salmon, mackerel, tuna, herring, and sardines are your best sources of omega-3 fatty acids, particularly EPA and DHA.
These two types of omega-3s play a vital role in maintaining optimal brain health.
Low levels of EPA and DHA have been linked to mood disorders, memory problems, and an increased risk of Alzheimer's disease. (2)
Leafy greens such as spinach, kale, and collards deserve a standing ovation when it comes to brain food for brain fog.
They're nutritional powerhouses packed with vitamins (especially Vitamin K, which is vital for brain cell activity), minerals (like folate and magnesium), and antioxidants like lutein. (3)(4)
Research suggests that just one serving of these leafy greens every day can have a profound impact.
That’s because leafy greens contain important compounds, like folate, that support healthy brain cell function and protect your brain from damage. (5)
We sometimes overlook one of the easiest ways to combat brain fog – staying well-hydrated.
The human brain is about 75% water. Dehydration can significantly impact your cognitive performance. (6)
Think of your brain cells like plump, juicy grapes. When you're dehydrated, those grapes start to resemble raisins.
They shrivel up, affecting their ability to function correctly.
Studies show losing as little as two percent of the water in your body negatively affects thinking and memory. (7)
It also impacts decision-making ability. Staying adequately hydrated helps keep those brain cells working at their best.
So, how much water should you drink? Up to 60% of the adult human body is made of water.
That’s why guidelines from the Eatwell Guide in the UK say to drink six to eight glasses of fluids a day, which includes things like unsweetened drinks, tea, coffee, and of course, water. (8)
Make it a habit to carry a water bottle.
Berries are brimming with antioxidants. These are vital for protecting your brain from oxidative stress. (9)
This refers to cell damage caused by free radicals – think of it like rust forming on your brain cells, impairing their function. (9)
This stress plays a role in brain aging and contributes to cognitive decline and neurodegenerative diseases. This can also be the culprit of experiencing symptoms of brain fog.
Blueberries get their vibrant color from flavonoids, particularly a group called anthocyanins, which research says keeps us hydrated like water.
Blueberries can enhance memory, improve learning, and even delay age-related cognitive decline. (10)
Add a handful of blueberries to your breakfast cereal or oatmeal.
Enjoy them as a snack, or blend them into a delicious smoothie. You can also incorporate them into baked goods.
When it comes to food for brain fog, eggs are a true nutritional superstar, often praised for their versatility and affordability.
But beyond these attributes lies an unsung hero: choline. Choline is an essential nutrient that plays a vital role in brain health.
Here’s why choline is so important. Your brain uses it to produce acetylcholine, a neurotransmitter essential for memory, learning, and muscle control.
Adequate choline intake helps support healthy brain development, improves memory, and may even protect against age-related cognitive decline. (11)
Many of us aren’t getting enough of it, which can significantly impact our cognitive function and overall brain health.
Mushrooms are a fantastic addition to a brain-healthy diet, particularly for combatting brain fog.
Rich in beta glucans, mushrooms help reduce inflammation and oxidative stress, which are often culprits behind cognitive issues. (12)
These fungi contain bioactive compounds such as ergothioneine and glutathione, known for their neuroprotective properties. (13)
Regular consumption of mushrooms has been linked to improved cognitive function and a reduced risk of neurodegenerative diseases. (14)
By incorporating a variety of mushrooms into your meals, you can enhance both flavor and brain health, making them a top choice for those seeking clarity and focus.
Oats are another powerhouse food for alleviating brain fog, thanks to their high content of beta glucans.
These soluble fibers help reduce inflammation and promote a healthy gut microbiome, which is closely linked to cognitive function. (15)
Oats provide a steady release of glucose, ensuring a consistent energy supply to the brain, which helps maintain mental clarity throughout the day.
Starting your day with a bowl of oatmeal or adding oats to smoothies and baked goods can be a simple yet effective way to support brain health.
By including oats in your diet, you provide your brain with the essential nutrients needed to stay sharp and focused.
Let’s start with the main offenders, processed foods.
We live in a fast-paced world, making ultra-processed foods so convenient and tempting.
Think fast food meals, packaged snacks, sugary drinks, and ready-to-eat meals – they might save time, but they wreak havoc on your brain.
Processed foods contain artificial sweeteners, preservatives, added sugars, unhealthy fats, and a long list of ingredients that are difficult to pronounce.
These components often contribute to inflammation in the body, including the brain.
This inflammation can disrupt brain cell communication and lead to cognitive issues like brain fog. (16)
These types of foods lack the essential nutrients your brain needs and can even hinder the absorption of vital vitamins and minerals.
They can cause blood sugar spikes and crashes that can trigger brain fog, fatigue, and difficulty concentrating.
White bread, pastries, and sugary cereals – these common culprits might give you a quick energy burst, but what goes up must come down.
They also lack fiber, so they’re quickly absorbed by your body.
These foods cause rapid spikes in blood sugar, which can lead to that all-too-familiar sugar crash, leaving you feeling foggy, fatigued, and mentally drained. (17)
Research even suggests a correlation between those blood sugar spikes in children and adults with memory impairment. (17)
The journey towards banishing brain fog begins with nourishing your body with the right foods.
It’s often easily corrected by incorporating simple food changes into your daily routine.
Start by focusing on a diet rich in whole, unprocessed foods. Avoid the obvious offenders. Remember that a healthy brain is key to a happy, fulfilling life.
Unfortunately, there's no "quick fix" when it comes to brain fog. It's usually a sign that something is out of balance in your body. Often this is our diet. The best way to get rid of brain fog is to identify the underlying cause, address it, and adopt a holistic approach to brain health.
Start your day by reaching for a large glass of water. Staying properly hydrated is crucial for optimal brain function. Other excellent choices are herbal teas like peppermint tea (which aids in digestion) and green tea, known for its cognitive-boosting properties.
Bananas can provide a quick energy boost and may temporarily improve cognitive function. But they’re not necessarily a magic cure for brain fog. While they provide some potassium (linked to cognitive function) and vitamin B6 (supporting brain health), they also contain relatively high amounts of natural sugar (fructose) compared to some other fruits.
