Bad Brain Foods You May Be Surprised Should Be Eliminated

The Bad Brain Foods 

bad brain foods

Bad brain foods exist. I wouldn't exactly classify them as evil, but then again, it depends on the day of the week and the level of temptation to indulge in some of these.  

As you may already know, I am a big proponent of implementing brain foods as a part of your everyday diet.

I have written a lot about the many great benefits that some of these foods provide to our brains.

Many of these foods are an excellent way to supplement the natural treatment of ADHD in both children and adults.

I also talk about the incredible value many of these foods have to support overall brain health and cognitive functioning for everyone. 

Brain Foods are all great, right?

Brain foods are great, right?

However, bad brain foods can have the opposite effect on our cognitive abilities. 

Consuming many of the foods from the brain foods lists I have provided can support and improve the overall health and cognitive functioning of our brains.

It is a topic I frequently share because it is something that is fairly easy to work with our everyday routines, no matter how busy our lives may be.  

Many of the good brain foods I have shared with you at Focus Here and Now, support focus, memory, cognitive function and overall brain health.

I personally consume these foods to naturally supplement and treat my own ADHD disorder.

However, there are also foods that are bad for the brain.

Many of you, including myself, were consuming some of these bad brain foods on a regular basis because some are far less obvious than others. Today, instead of sharing another list of good brain foods you should be consuming, I am going to discuss the brain foods you should avoid. The foods that are quite frankly, bad for the brain.

Today, instead of sharing another list of good brain foods you should be consuming, I am going to discuss the brain foods you should avoid. The foods that are bad for the brain.

Fast Foods as Addictive as Hard Drugs?


Even though we may be in denial because that juicy bacon cheeseburger looks and smells so good, I can confidently surmise that the majority of us know that certain foods, especially fast foods, are not good for our overall health. 

Before I get into some of the bad brain foods, I want to address just how bad fast food can be for the brain.

Yes, we all know fast food is not “good for us,” but what kind of effect does it have on our brains? 

The fact is that they have addictive qualities and effects similar to that of certain illegal hard drugs.

A recent study in an article released by CNN found that certain foods can be just as addictive as certain narcotics.

This includes heroin, cocaine, and opiates. 

Studies about Bad Brain Foods

These studies showed that these foods had very powerful effects that left consumers with a similar euphoric feeling as these drugs.

The article discusses the correlation and specifics of the study. This can be very concerning, especially for those who suffer from ADD or ADHD, who are prescribed stimulant medications like Adderall and/or Ritalin.

I know from personal experience, my appetite would get so suppressed throughout the day, I found myself with few options other than late night fast food runs.

The addictive qualities of these foods are alarming and contribute to negative brain health, as much as the rest of the body. This fact is often overlooked.

Digest what will help our minds, not hurt it. This site provides very simple suggestions, information, recommendations, and options to supplement healthy brain foods into your daily routine. However, there are other lesser-known foods that are bad for your brain. 

Today, we will examine a list of some of the bad brain foods, you should consider removing from your diet.


The NOT Top 5 Brain Foods List – Bad Brain Foods You Should Avoid (Part 1)

egg yolk brain food

       1. Egg-White Omelette

Removing the yolk from the eggs is also eliminating some important nutrients that are very beneficial to the brain. 

Alternative: Include the Yolk, as it contains the neuroprotective nutrient: choline. Research shows that adults who received more choline in their diets performed better on verbal and visual memory tests and may be less likely to suffer from cognitive decline later in life.

Research shows that adults who received more choline in their diets performed better on verbal and visual memory tests and may be less likely to suffer from cognitive decline later in life.

Choline is an essential nutrient and a natural nootropic that we had discussed when defining nootropics functions in an earlier article I shared called, Do Nootropics Work? Choline is also an essential ingredient found in some of the higher quality nootropic supplements, commonly hyped in the media as “smart drugs.

Some of the higher quality nootropic supplements, such as OptiMind, which I recently reviewed, discusses not only the supplement, but also provides more detailed information about the choline nootropic supplement and its benefits.

bad brain food tuna

       2. Tuna

Listen, I like Tuna and it is a great source of protein and can be a fairly healthy food in small doses and without globs of fattening mayonnaise mixed into it. 

However, it considered a bad brain food. Tuna has higher than average amounts of mercury, especially in the typical canned tuna that many of us buy from the grocery store.

It is a bad brain food. Tuna has higher than average amounts of mercury, especially in the typical canned tuna that many of us buy from the grocery store.

The brain, the heart, kidneys, lungs, and nervous system can all be susceptible to the harmful effects of mercury. Check the labels, especially if you are buying tuna for children with or without ADHD, as they are more commonly affected. 

Many recent studies have shown that those consuming higher amounts of mercury in foods, such as tuna, had scored 5% lower in cognitive tests.

Alternative:  Choose a Low-mercury seafood, such as salmon, sardines, and whitefish.



bad fried brain food

       3. Fried Foods  

This one may sound a little more obvious in terms of it not being an ideal healthy food source for your daily diet.

However, do you know the effects that fried foods have on your brain? Almost all processed foods contain chemicals, dyes, additives, artificial flavors, preservatives and such – these can affect behavior and cognitive functioning, due to the chemical that causes hyperactivity, both in children and in adults.

Meaning, fried foods are especially bad for ADHD children and ADHD adults.

Fried or processed foods slowly destroy the nerve cells located in the brain. However, some oils are more dangerous than others – sunflower oil is considered to be among one of the most toxic. Fried foods contain chemicals called, advanced glycation end products, or AGE’s.

These can advance cell aging and inflammation and have been known to be responsible for compounding and developing degenerative diseases. Scientific research has found that people with high levels of AGE are more likely to have complications with their mental process and memory.


Bake or broil food instead. This includes meats, chicken, and especially fish. The omega 3 fatty acids found in fish have multiple benefits not only for the brain but positively support your overall health.

So, avoid those unhealthy fried foods because they are having just as much of a negative effect on your mental health, as they are to your physical health.



processed bad brain food

       4. Processed Or Pre-Cooked Foods

Just like fried foods, processed or pre-cooked foods also impact your central nervous system and they also increase the risk of developing a degenerative brain disorder later in life (such as Alzheimer’s disease).

These foods lose all their nutrients while they are being processed. They also contain so many sugars, various additives, and artificial flavors that have been linked to other brain disorders, including, dementia.

Additionally, many of these foods contain a high level of trans fats. Trans fats interfere with our metabolism, denying essential fatty acids to brain cells that can cause harm to neurotransmitters. 


Find a farm, farmers market, or join a CSA. Purchase food that is both local and organic. Ask friends, family members, and co-workers for referrals to green markets or CSAs in your area. You can also search Local Harvest to find local—and organic—food near you. It is an excellent resource.

I noticed a significant change in how I have felt both mentally and physically since I've added primarily organic and whole foods into my everyday diet. I guarantee you will also notice a big difference in how you feel!




bad brain food grains

5. Grains (YES, Grains!) – 

With the exception of 100% Whole Grains, different types of grains have an impact on your brain functioning and overall health.

Research has revealed that eating a high carb diet may be linked to dementia. Consuming grains puts your body at risk to age more quickly and can contribute to memory loss and brain fog.

Alternative:  Try swapping the regular carbs for the complex carbohydrates – all you need to do is to opt for whole grain bread! 100% whole grains are very rich in fiber and are known to prevent arterial aging.


Conclusion about Bad Brain Foods

Brain foods are a hot topic that I frequently discuss at Focus Here and Now. Lately, we have discussed the best brain foods that you should be consuming on a regular basis.

However, as demonstrated above, not all brain foods are created equally. Foods we may have believed provided positive health benefits can be considered bad brain foods.

Supplement a well-balanced diet of certain brain foods as it can be extremely beneficial, not only to those who suffer from ADHD or ADD, but also to positively support our overall mental health. It is extremely important to know which foods to implement into our daily diets.

Supplement healthy brain foods and exercise, pick up routines, suggestions, recommendations, and certain supplements to achieve optimal cognitive functioning and brain health.

I will be sharing part 2 of this topic in the upcoming days and address 5 more foods that are not ideal for optimal brain health.
