Are you tired, run down, or depressed all of the time? Your brain fog and diet may be more closely linked than you think.

That cloudy feeling in your mind could be caused by a host of things, but diet plays a massive role. Brain fog and diet are connected, and changing what you put into your body can have a drastic effect on how you feel.

Ahead, we’ll take a look at some of the foods you can eat that may clear your brain fog, as well as foods to avoid to prevent it from occurring in the first place.

Symptoms of Brain Fog

Before we get into diet recommendations, let’s go through a brief rundown of brain fog. You might be experiencing brain fog on a daily basis without even knowing it.

Brain fog is a general term, and it refers to feeling run down, tired, irritable and depressed. You may notice a lack of clarity in your thoughts and general confusion.

People experiencing brain fog often have difficulty concentrating on a task, and might just feel a bit off. You may also have trouble remembering things during brain fog periods.

Brain fog can also lead to more serious mental conditions like anxiety and depression, especially when it surrounds your work habits. You might begin to feel like you’re not working to your full potential, which can be aggravating.

There are several culprits when it comes to brain fog. Not getting enough sleep, for instance, is a recipe for experiencing brain fog throughout the day.

Brain Fog and Diet: Foods and Supplements

Diet plays a massive role in how you feel, so there’s no wonder brain fog and diet are closely related. Here are some alterations you can make to your diet to avoid feeling the fog.


Yogurt is a great brain fog antidote because of its probiotic content. We receive the bulk of or serotonin from our stomach, and probiotics are traditionally associated with improving gut health.

Those who don’t like yogurt or don’t get enough probiotics from their diet can turn to supplements. Of course, supplements may not be as effective as the real thing.

Vitamins and Minerals

Brain fog and diet are strongly related to insufficient vitamins and minerals. Many people don’t get enough vitamin D, C, and B in their diet, and need to take supplements to get the proper amount.

Vitamin C and D, specifically, help regulate your mood and improve your brain health. You may begin to feel better once you start taking more vitamins, if you’re not getting enough from what you eat.

Minerals like zinc are also extremely important to brain development, and can improve your overall brain health.


Celery is fantastic brain food and can help protect you from long-term brain deterioration. This is due to its luteolin content, a plant compound believed to reduce brain inflammation. It may also help with your memory, depth perception, and your ability to learn new things.

Celery isn’t the only vegetable that can help you in this way. Green capsicum and chamomile tea are also sources of luteolin.

Foods to Avoid

Now that we’ve given you a few foods and supplements to help clear brain fog, we’ll advise you on what you should stay away from if you want to keep brain fog at bay. Problems with brain fog and diet can compound over time, so the earlier you can change your habits, the better.


Caffeine is a fantastic way to clear short-term brain fog, but it can add to the problem if you’re a regular coffee drinker.

Research on the benefits of black coffee is plentiful, but that doesn’t mean it will work well for everyone. Those who overindulge may develop a dependence on caffeine, leading to increased brain fog after the caffeine wears off.

More brain fog leads to more caffeine to get you through the day, and your dependence grows stronger. Eventually, you might even start to lose sleep from having too much caffeine, which leads to more brain fog the next day.

This doesn’t necessarily mean you have to give up caffeine entirely: drink coffee and other caffeinated beverages in moderation.


Sugar is delicious, and like coffee, it can temporarily allow you to escape the brain fog feeling. Unfortunately, your brain fog can come back with a vengeance if you eat sugar too often.

If you’re craving the sweet stuff, try to get it from natural sources like fruit or honey. It may not be as exciting as a scoop of ice cream, but your brain will thank you.


Although celiac disease is relatively rare, some people might have an undiagnosed gluten intolerance. Eating gluten, in these cases, leads to the cloudy feeling we’re trying to avoid.

Additionally, eating gluten can lead to increased inflammation over time, which affects how the brain operates. If you regularly experience brain fog, try avoiding gluten for a few weeks and see if you notice a difference.
