Can you get brain fog from food? What you eat has a significant impact on your body, including your brain. This is no wonder, as 20% of the energy you consume through food goes to your brain.
A healthy diet includes vitamins, minerals, fiber, and antioxidants. If you get enough of these, your brain's nerve cells can communicate properly and effectively. However, consuming the wrong foods can lead to problems like brain fog.
Brain fog is a condition where you feel foggy, unfocused, and confused. You have difficulty concentrating and processing new information. Certain foods can cause brain fog, such as sugar, unhealthy fats, alcohol, and drugs.
Consuming or using too much of these can lead to impaired brain function or even damage. This blog post explains the connection between diet and brain fog.
Sugar, bad fats, alcohol, drugs, gluten and casein disrupt brain function, cause inflammation and reduce concentration.
Damaged blood vessels, neurotransmitter imbalances, decreased memory function and increased inflammatory responses lead to mental fatigue and confusion.
Limit sugar, trans fats, alcohol, and gluten; choose A2 milk and eat anti-inflammatory foods for clear brain function.
Brain fog from refined sugar
Refined sugar is one of those foods that can cause brain fog. Research shows that high sugar consumption can cause inflammation, which leads to the formation of AGEs (harmful compounds that accumulate in the bloodstream).
This can damage the blood vessels in the brain. High sugar consumption can therefore lead to memory problems.
Diabetes involves highly variable blood sugar levels. When insulin is too high, it can lead to brain dysfunction [1] .
Furthermore, sugar inhibits the production of BDNF. BDNF stands for brain-derived neurotrophic factor, a substance that can prevent and repair damage to nerve cells. It plays a key role in creating new memories and learning.
Another danger of sugar is that it can lead to atherosclerosis (narrowing of the blood vessels). This causes high blood pressure throughout the body, including in the brain.
Research shows that high blood pressure can damage blood vessels in the brain, leading to mild cognitive impairment. However, it can also contribute to the development of a more serious condition, Alzheimer's disease.
Brain fog due to bad fats
When we look at brain fog caused by food, we also come across the wrong fats. These are, for example, vegetable fats that have oxidized. This happens when they are heated too much.
At high temperatures, unsaturated fats become unstable, a process comparable to rusting. The end product is very unhealthy and can lead to health problems and brain fog.
Another problem is that in the Netherlands, we consume disproportionately too many omega-6 fats. We need these fats for our health, but if you eat too much, an imbalance between omega-3 and omega-6 fats occurs. These fats are found in products like margarine, sunflower oil, and dressings.
Omega-6 fats promote inflammation, creating free radicals that can damage the cells in your body and brain. This can also impair brain function.
Other fats that can cause problems are trans fats. These are unnatural, processed fats made from vegetable oils. They are widely used in frying fats, margarines, pastries, and chips, among other things.
Trans fats can raise HDL cholesterol and lower LDL cholesterol. They can also disrupt your hormone balance and cause inflammation in the brain. In this way, trans fats can also contribute to brain fog.
Brain fog from alcohol and drugs
Both alcohol and drugs can cause oxidative damage to the brain, which can have negative effects in the short and long term. Alcohol and drugs generally have a negative impact on brain function [2] .
The areas responsible for memory, concentration, and logical thinking are particularly affected. People who use a lot of these substances often find they lose sight of their ambitions and can no longer muster any motivation. You can also eventually develop brain fog.
That's not surprising when you consider what these substances do to your brain. They disrupt the balance of neurotransmitters and cause chronic inflammation in your brain.
It's crucial for both your physical and mental health to reduce or even completely stop using alcohol and/or drugs. The clarity of mind and the feeling of being yourself again that you gain make it worth the effort to swear off alcohol.
Brain fog from gluten
Another cause of dietary brain fog is gluten. It's common in celiac disease patients (90% of celiac patients who participated in a survey reported experiencing this regularly).
How can gluten cause brain fog? Gluten increases the level of a substance called zonulin in the intestines. This can lead to increased intestinal permeability, which allows zonulin to enter the intestinal contents. This, in turn, leads to chronic inflammation in the body and brain.
Research shows that there is a strong link between inflammation, such as that found in celiac disease, and decreased brain function [3] . As such, it can cause brain fog.
Furthermore, gluten can cause neurological damage. Evidence suggests that gluten is the underlying cause of an "overstimulated celiac brain." Frequent overstimulation is a well-known characteristic of brain fog.
Then there are the gliadorphins. These are exorphins (opiate-like substances) that are released when gluten isn't fully digested. They can cause a neurotransmitter imbalance.
A final reason gluten can cause brain fog is that it can lead to vitamin and mineral deficiencies. If the intestinal wall is damaged due to gluten sensitivity, the intestines are less able to absorb nutrients.
You may then develop a deficiency of folic acid, vitamin B12, or iron, for example. This can, in turn, cause brain fog.
If you stick to a gluten-free diet, you will no longer suffer from gluten-related brain fog.
Brain fog caused by casein
If you often experience brain fog, it could also be caused by the casein in dairy. Not everyone is sensitive to this, but if your body has difficulty digesting or absorbing casein (a protein in milk), it can lead to brain fog.
When casein is incompletely digested, casomorphins (also known as exorphins) are released, which can disrupt the neurotransmitter balance. This can lead to problems with memory, concentration, and, for example, difficulty finding words. In short, you suffer from brain fog.
If you like milk, it's better to choose A2 milk. It's mainly A1 milk that can cause problems.
