Your brain is an intricate and remarkable organ that makes you uniquely you. Our brain is the powerhouse that controls every thought we think, emotion we feel, and action we take. And this delicate network between our ears is uniquely susceptible to a toxin that’s become a growing concern in our increasingly toxic world.
The toxin I’m referring to is the widely used herbicide known as glyphosate. Today we’re going to explore the impact that this complex chemical has on our brain health and what you can do to protect yourself. Let’s dive in.
What Is Glyphosate?
Glyphosate is an herbicide – a fancy term for a substance used to control unwanted plants, commonly called weeds. The weed-killing magic of glyphosate lies in its ability to inhibit what’s known as the shikimic acid pathway. This is a critical metabolic pathway that plants use to produce the enzymes and compounds they need to survive.
Glyphosate inhibits or blocks the activity of the shikimic acid pathway. Once this switch is turned off, the weeds weaken until they eventually wither away and die. This remarkable ability to selectively target and kill certain plants has made glyphosate highly useful in the world of agriculture – making it one of the most widely used herbicides across the globe.1,2
Because we as humans don't use the same shikimic acid pathway for synthesizing essential molecules, some argue that this potent herbicide doesn’t cause harm to our bodies. But simply looking at whether or not glyphosate interrupts this specific metabolic circuit in the human body doesn’t give us the whole picture of what this herbicide really does to our health – not even close.
Is Glyphosate Harmful To Humans?
In short, the answer to this question is – yes! Glyphosate exposure has been linked to a number of health concerns including:3,4
- Cancer
- Kidney disease
- Reproductive issues
- Birth defects
- Endocrine disruption and hormonal imbalances
- Gastrointestinal issues
- And more
But research is finding that glyphosate’s effects don’t end there. This herbicide can also have some frightening effects on your brain.
What Does Glyphosate Do To Your Brain?
Glyphosate can disrupt the delicate balance within your brain and cause damage via several distinct pathways. Let’s zoom in on each of these.
Disruption of the Gut-Brain Axis:
While we as humans don’t have the shikimic pathway, the microbes that make up our gut microbiome do. Many species of bacteria that reside in our gut rely on the shikimic pathway to produce essential metabolites and function optimally. Glyphosate’s interference with this crucial ability can shift the balance of your gut microbiome – causing beneficial bacteria to decrease and not-so-beneficial bacteria to begin overpopulating.
And this shift in the ecosystem of your microbiome (referred to as dysbiosis) is no small matter when it comes to your brain health. You see, your gut and your brain are directly connected via a superhighway known as your gut-brain axis. When your gut microbiome is disrupted, it negatively affects the signals transmitted along the gut-brain axis. This, in turn, negatively influences brain function and health.5,6
Decreased Short-Chain Fatty Acids:
Another side effect of this alteration to your microbiome is a decrease in the production of molecules known as short-chain fatty acids. You see, when certain beneficial bacteria break down the food you eat, they produce many beneficial by-products – one of which is short-chain fatty acids.
These fatty acids are crucial for countless processes throughout your body. But one place that they play an especially important role is in your brain health. These tiny fatty acid chains serve as a source of fuel for your brain cells, shield your brain from inflammation, help modulate gene expression, and regulate your brain's immune response to name just a few important roles they play.
So, when glyphosate interferes with your gut microbiome it has a domino effect – putting a damper on the production of these important, health-boosting molecules.7,8
Impaired Blood-Brain Barrier Integrity:
Your blood-brain barrier is a membrane that tightly regulates the passage of substances between your bloodstream and your brain. There is some evidence suggesting that glyphosate may affect the integrity of this crucial blood-brain barrier – potentially allowing substances to enter the brain that would normally be restricted.
That means glyphosate can potentially allow toxins and other irritating compounds to leach their way into your brain where they can stir up inflammation and oxidative stress.9
Inflammation and Oxidative Stress:
Glyphosate and its effects can spark inflammation in your brain – activating your immune system as it attempts to neutralize the perceived threat. Sustained and uncontrolled inflammation can eventually lead to what’s known as oxidative stress – a process that occurs when there is a surplus of unstable molecules known as free radicals. These reactive molecules steal electrons from your cells in an attempt to stabilize themselves.
This robbing of electrons inevitably leaves your cells damaged and unable to perform their duties at full capacity. Accumulated damage can permanently alter cellular structure and even damage DNA – potentially leading to cell mutation or cellular death. Oxidative stress in your brain can lead to damaged neurons and deterioration of the protective sheath designed to protect the cells of your nervous system.10
Endocrine Disruption and Neurotransmitter Imbalance:
Your brain relies on tiny chemicals known as hormones and neurotransmitters to communicate with other parts of your brain and the rest of your body. Even small fluctuations in these molecules can trigger significant changes in the signals your brain is sending out. Glyphosate can disrupt this delicate balance of communication chemicals – leading to changes in brain health, mood, cognition, and more.11
It’s this combination of effects on your brain that makes glyphosate so concerning. Now that you have an understanding of what’s going on at the cellular levels when you’re exposed to glyphosate, let’s zoom out a little and look at how all of these underlying changes can add up.
Glyphosate Neurotoxicity: Neurological Conditions Potentially Linked To Glyphosate
Research is finding that glyphosate's damaging effects on brain health can add up – eventually contributing to a whole host of brain-based conditions including:12,13,14
- Alzheimer's disease: There is ongoing research exploring potential links between glyphosate exposure and Alzheimer's disease, a progressive neurological condition characterized by cognitive decline.
- Attention-deficit/hyperactivity disorder (ADHD): Glyphosate exposure has been explored as a potential factor in the development or exacerbation of ADHD, a neurodevelopmental disorder affecting attention and impulse control.
- Autism spectrum disorders (ASD): Research has suggested potential links between glyphosate exposure and the risk of autism spectrum disorders, which are characterized by difficulties in social interaction and communication.
- Cognitive impairment: Studies have investigated the impact of glyphosate on cognitive function, with some suggesting potential associations with cognitive impairment.
- Depression and anxiety: Imbalances in neurotransmitters, potentially influenced by glyphosate, have been associated with mood disorders such as depression and anxiety.
- Epilepsy: Some studies have investigated the potential role of glyphosate in epilepsy, a neurological disorder characterized by recurrent seizures.
- Neurodevelopmental disorders: Glyphosate exposure has been studied for its potential impact on neurodevelopment, and associations have been proposed with neurodevelopmental disorders in children.
- Other neuroinflammatory conditions: Glyphosate's potential to induce inflammation has led to hypotheses about its role in neuroinflammatory conditions, which are implicated in a wide variety of neurological disorders.
- Parkinson's disease: Some studies have suggested associations between glyphosate exposure and an increased risk of Parkinson's disease, a neurodegenerative disorder affecting movement.
With such serious implications for your brain health, you’re probably wondering what you can do to protect yourself from glyphosate.
How Can I Protect Myself From Glyphosate?
Given the extensive use of glyphosate and its pervasive presence in the environment, it’s impossible to entirely avoid glyphosate. But not to worry, simply taking some steps to minimize your exposure to this herbicide can go a long way in shielding your brain from the toxic effects of glyphosate. Here’s what you can do:
Prioritize Organic and Non-Gmo Foods:
Opt for organic and non-genetically modified organism (GMO) foods. GMO crops are often treated with high levels of glyphosate and other chemicals. Choosing organic options, including produce, coffee, and animal products, can significantly reduce your exposure.
Minimize Your Overall Toxic Burden:
Your body is more than capable of handling small amounts of toxins. It’s when your system gets so bogged down that these toxic compounds begin accumulating is when things get tricky. Doing things like making low-tox swaps, supporting your natural detoxification pathways, and incorporating toxin-trapping detox binders (like ZeoBind Plus) can help your body better eliminate unavoidable glyphosate exposure.
