(Uma Naidoo) In my work as a nutritional psychiatrist, I support people with a variety of neurological and psychiatric concerns, ranging from pervasive conditions like depression and anxiety to day-to-day issues such as poor sleep, difficulty focusing, and, you guessed it — brain fog. While brain fog can be a symptom of many different diseases and syndromes, it can also be a result of foods in our diet that affect our blood sugar levels, oxygen supply to the brain, or inflammation anywhere along the process of thought and mood formation.

What Is Brain Fog?
What Causes Brain Fog?
The causes of brain fog can range from fairly benign to quite serious. On the dangerous end of the spectrum, it can be a symptom of serious conditions, like hypoglycemia, nutrient deficiencies, impaired blood glucose control, viral infections, or even stroke. If you find yourself with a sudden onset of brain fog, especially alongside symptoms of dizziness, a sudden fall, or weakness in your limbs/drooping of your face, please seek emergency medical care immediately.
Other causes of brain fog can include chronic conditions like fibromyalgia or chronic fatigue syndrome, or a transient response to food or environmental triggers. These include a “crash” after ingesting high amounts of sugar or caffeine, or as part of the symptoms reflecting an underlying food intolerance. Of note, long COVID syndrome is now also being associated with brain fog.
What Does Brain Fog Feel Like?
While there is no clinical diagnosis for brain fog, it is reported that symptoms of brain fog may include:
- slow thinking
- difficulty focusing
- confusion
- lack of concentration
- forgetfulness
- haziness in thought processes
Other than the cognitive symptoms, brain fog generally doesn’t feel like much — perhaps it may be associated with a headache, in the case of a hangover, but if any other physical symptoms present alongside it, this is also a reason to seek medical care.
Why Brain Fog Is Harmful
Short-Term Consequences of Brain Fog
In an immediate sense, the most pressing consequences of brain fog may be slowed productivity, thinking, or decision-making, which may negatively impact your ability to complete work or tasks at home. If your work involves operating heavy machinery, for example, not being at your cognitive best can be particularly risky.
Long-Term Consequences of Brain Fog
Long-term consequences of brain fog are numerous. Continuing from the above example, lost productivity over a long period of time can have deleterious impacts on one’s career or work output.
From a “root cause” perspective, repeated episodes of blood sugar “crashes” can precipitate or worsen an underlying metabolic syndrome, contributing to conditions like diabetes, obesity, or high cholesterol.
Relying on caffeine to “fuel up” for the day and then “reboot” after an inevitable crash can also contribute to feelings of anxiety in those predisposed to it and poor sleep over a long period of time. In turn, chronic insomnia is implicated in many physical and psychiatric conditions, from diabetes and hypertension to depression, anxiety, and even dementia.
In terms of recovery from long COVID or long haulers syndrome, research is ongoing but we know that a sound diet rich in anti-inflammatory foods is always helpful in cases of neuroinflammation. Starting there is a good first step.
How Food Can Make Brain Fog Better or Worse
Plainly speaking, avoiding foods that may contribute to brain fog and choosing foods that prevent it provide us with tangible means of optimizing our personal and professional performance. Using foundational principles of nutritional psychiatry, when we tap into our body’s own intelligence and mindfully add foods to our plate which truly nourish the brain, we unlock the potential to be our best selves — with every bite we take.
Worst Foods for Brain Fog
Here are some of the ways diet can contribute to brain fog, as well as some tips on how you can optimize with better choices.
- Too many simple, refined, and processed carbs: Foods like pastries, cookies, crackers, and white bread/grains can throw your blood glucose out of whack. Instead, choose foods rich in fiber to reduce sugar cravings, and opt for low-glycemic fruits like berries.
- Too much caffeine: This is especially true if consumed in combination with refined sugars, flavorings, and processed creams. Focus on tapping into your body intelligence to choose foods that bring you sustained energy.
- Alcohol, especially in excess: While low to moderate alcohol consumption may be fine in some cases, it is best to examine this choice on an individual basis — perhaps with the help of a doctor or mental health professional. If you notice that you crave alcohol, or ever drink more than you intended, it might be time to reconsider your relationship with drinking. You probably know this already, but it bears repeating: excessive alcohol consumption is literally poison for your brain.
- Foods that trigger unknown allergies: If you have chronic fatigue, joint aches, muscle pains, headaches, memory problems, or other persistent brain fog symptoms, this is something that certainly warrants a thorough medical evaluation and your doctor may need to check some blood work.
- Foods that trigger undiagnosed digestive troubles, including SIBO, ulcerative colitis, or Crohn’s disease: Common trigger foods for digestive issues include dairy, fried or processed foods, sugar, refined grains (especially ultra-processed wheat), carbonated sodas, caffeine, and alcohol. Large meals can also disrupt your gut-brain balance — it’s best to listen to your body’s needs and eat in a way that leaves you feeling nourished and not sluggish.
Top 5 Food Tips For Getting Rid of Brain Fog
On the other hand, nutritional psychiatry teaches us that we can take advantage of the properties of brain foods to boost our energy and clarity. The following pearls of advice are my fundamentals when it comes to optimizing cognition.
1. Beat brain fog with colorful fruits and veggies.
Fiber-rich, plant-based foods are packed with antioxidants, polyphenols, flavanols, vitamins, and minerals that help reduce inflammation in the brain and resist the effects of oxidative stress (the kind that damages cells, and even leads to premature aging). These superfoods can help improve focus, reduce fatigue, and enhance cognition for optimal performance.
I encourage you to try this out as a game with your family and friends: see how many new colors you can add in a day or a week to enhance the biodiversity in your diet. And another plus — eating the rainbow has also been linked to improved gut health!
2. Cook with herbs and spices.
Cooking with herbs and spices adds a delicious punch of brain-boosting molecules to food! For example, turmeric has an active ingredient called curcumin which has potent anti-inflammatory and antioxidant properties supporting positive moods and sharper focus. When you add turmeric with a pinch of black pepper to your cooking, the black pepper enhances curcumin absorption twentyfold. It’s also easy to add a teaspoon (with a pinch of black pepper!) to a warm tea, nourishing soup, or fresh smoothie.

3. Follow your body intelligence surrounding caffeine and alcohol.
Many of us “power up” in the morning and throughout the day with the help of caffeine, and then wind down in the evening with wine or cocktails. While both of these substances may have some health benefits when consumed in moderation, their effects are also highly specific to each individual and their microbiome. This is where I suggest tapping into your body intelligence, one of the pillars of nutritional psychiatry.
Pay close attention to whether caffeine helps you improve focus, or is actually overstimulating and causes uncomfortable jitteriness. Similarly, it’s important to gently recognize if, after a wine or cocktail, you toss and turn at night and wake up feeling poorly rested. This awareness can guide you to potentially adjust your consumption — I believe in balance! — to resist any negative impact on mental health and work productivity.
4. Stay hydrated for brain health.
Remaining properly hydrated is key for optimal brain health and function! Many symptoms of poor mental health and cognitive function are tied to dehydration. Dehydration can worsen or even precipitate anxiety, while conversely, staying hydrated is associated with decreased depression and anxiety.
Sipping on water throughout the day and including hydrating fruits and vegetables in the diet, such as cucumber and leafy greens, help maintain a steady supply of water within the body. Keep a stainless steel or glass water bottle on your work desk and remember to refill it a few times every day, or set a reminder on your phone to keep sipping!
5. Snack on nutrient-dense brain foods.
When hunger pangs strike between meals, or when you’re in need of a “pick-me-up,” opt for brain foods that help keep your cognition tip-top and sharp. Due to the location in the brain, hunger and thirst signals are sometimes confused, so try sipping on some hydrating water to overcome hunger pangs until you can reach out for a healthy, brain-food-filled snack.
Some of my favorite focus-enhancing snacks are a small square of extra dark (80%+) natural chocolate, a handful of walnuts, or a dish of berries, all of which contain fiber, antioxidants, vitamins, and minerals that enhance our brainpower.
Or you can combine all of these foods into one superfood snack like this creamy and dairy-free chocolate mousse:
