Everything you eat directly affects the functionality of your brain. If you eat healthy foods then your brain functions will be improved* as well, but some foods can damage your brain. This article will list 5 foods that are harmful for your brain.
1. Salty Foods
Salty foods have a negative effect on your heart, kidneys, and your brain as well. A study which lasted for 3 years and included 1200 participants revealed that people with the highest level of sodium in their body and the lowest level of exercise had poorer scores on cognitive tests than people with low level of sodium in their body and active lifestyle.
Some foods that belong into this category are:
- Pasta sauce
- Instant noodles
- Mixed nuts
- Bottled salad dressing
- Tortilla chips
- French fries (again).
2. Fatty Foods
Fatty foods are bad for your overall health and that refers to your brain as well. The Journal of Clinical Investigation published a study which revealed that fatty foods damage the hypothalamus. This part of the brain is in charge of numerous functions and hormones, e.g. hunger, sleep, moods, natural functions in the body, thirst etc.
Moreover, Neurology journal published results of the research which discovered that regular intake of fast food leads to brain shrinkage which can lead to Alzheimer’s disease.
These foods belong into this category:
- French fries
- All deep fried foods
- Microwave popcorn
- Creamy frozen drinks
- Potato chips
- Pork sausage links
- Cheese and crackers

3. Fried Foods
As it was mentioned above, you should always strive to avoid fried foods. Scientists from Spain discovered that compounds that are released from cooking oils increased the risk of some neurological degenerative diseases e.g. Alzheimer’s disease or Parkinson’s disease. These compounds are formed when the oil is heated to normal frying temperature.
However, if you think that change of the oil might change the outcome you are wrong. Scientists tested sunflower oil, flaxseed oil, and olive oil. All tested oils released these compounds in frying temperature; however flaxseed oil and sunflower oil created more compounds in shorter amount of time.
Some examples of fried foods:
- Buffalo wings
- Fried chicken
- Corn dog
- Egg rolls
- French fries yet again.
4. Processed Foods
Processed foods are bad for your health. Food additives, preservatives, food dyes have a negative impact on cognitive functions and behavior in children. Lancet published a study in 2007 which revealed that excessive intake of processed foods, foods that contain additives and food colorings can lead to hyperactivity.
Artificial food additives are consisted of about 3000 different chemicals that are added to your food. Naturally, consumption of this foods isn’t beneficial for your health and things get even worse when you eat this type of food on daily basis. For MSG that is used to emphasize the flavor of the food destroys nerve cells in the brain and encourages seizure-like behavior.
A study from 1984 discovered that exitotoxins additives affect the nervous system.
Some examples of processed foods are:
- Processed meats
- Packaged baked goods
- Frozen dinners
- Savory snacks
- Canned vegetables
- Microwave meals.

5. Foods That Contain Pesticide Residue
One study inspected the data from more than 25 million children and discovered that organophosphate pesticides affect IQ in children and preterm birth and ADHD. Nature Neuroscience published the results of the study which showed that long-term exposure to pesticides can kill brain cells and trigger symptoms that are linked with Parkinson’s disease. Increased intake of foods that contain pesticide residue leads to loss of neurons in some areas of the brain.
Some examples of food of this category are:
- Fruits, especially berries.
Naturally, as this type of food is of extreme importance for your health, this doesn’t mean you have to eliminate* fruits and vegetables from your diet plan. Here are some ways to avoid eating pesticides with your food:
- Wash produce thoroughly
- Dry the produce with clean towel or paper towel
- Throw away the outer layers of leafy vegetables e.g. kale or lettuce
- Don’t limit yourself on one fruit type or vegetable type, eat variety of produce.
Tips for Better Health and Brain Function
- Instead of frying the food, you should bake or cook
- If you love dairy products then buy ones with reduced* level of fat
- Instead of buying instant meals, cook your lunch and dinner
- Unprocessed meat is always better than processed meat
- Include a lot of fruits and vegetables into your diet and don’t forget to wash them of course.
Some foods like processed foods, fatty foods, fried foods etc. can harm your brain by decreasing* cognitive functions and leading to serious diseases like Alzheimer’s disease or Parkinson’s disease. You should stay away from fried food and eat cooked or baked food. Include fruits and vegetables into your diet and make sure you wash them thoroughly when you bring them home from the store.
