PUFA and endotoxins contribute to Alzheimer’s disease, while Tau and beta amyloid protect the brain

You might have heard that the buildup of tau and beta-amyloid proteins within the mind can result in Alzheimer’s illness. Nonetheless, rising proof means that these proteins could also be a protecting response to the underlying drawback relatively than the underlying reason for the illness.

Analysis printed within the journal Nature Neuroscience gives extra insights into the position of tau protein in mind well being, difficult long-held beliefs about its hyperlink to Alzheimer’s illness.¹ Analysis reveals that tau protein protects your mind cells from oxidative stress and poisonous lipids.

It seems that the Tau protein is crucial for the formation of lipid droplets in glial cells, the assist cells that encompass and defend neurons. These lipid droplets act as a protection mechanism, serving to to neutralize dangerous oxidized lipids that harm mind cells.

When the researchers elevated tau protein ranges in glial cells, they disrupted this protecting course of, making the cells extra prone to poisonous lipids produced by careworn neurons. In different phrases, tau protein buildup in Alzheimer’s illness often is the mind’s try and struggle ongoing harm, relatively than the perpetrator.

Tau’s constructive results on mind well being

The mind’s glial cells are essential for sustaining cognitive well being and have developed an enchanting mechanism to guard your mind from oxidative stress. When your neurons expertise excessive ranges of reactive oxygen species (ROS), they produce and launch poisonous lipid peroxide (LPO) as a self-protection technique.

LPO is what occurs when PUFA is broken. Your glial cells then come to the rescue, taking on these harmful lipids and storing them in lipid droplets.²

This course of acts like a cell recycling program, along with your glial cells safely containing and breaking down poisonous lipids which may in any other case harm your neurons. Analysis has discovered that the tau protein is crucial for the correct functioning of this protecting mechanism.

With out sufficient tau protein, glial cells have problem forming these protecting lipid droplets, making neurons extra prone to oxidative harm. The invention highlights the significance of sustaining a fragile steadiness of tau proteins within the mind – too little and an excessive amount of may cause issues.

Accumulation of beta-amyloid is a protecting mechanism

One standard principle about Alzheimer’s illness is that the buildup of amyloid-beta (Aβ) plaques is the first reason for cognitive decline. Nonetheless, an rising variety of research point out that Aβ performs a protecting position within the mind.³

A examine printed within the journal Alzheimer’s Illness and Dementia,⁴ A correlation was discovered between Aβ accumulation and glucose metabolism within the brains of Alzheimer’s illness sufferers. Opposite to standard perception, areas with increased common glucose metabolism confirmed higher Aβ deposition. This means that, as a protecting measure, Aβ could also be extra prone to accumulate in mind areas with increased metabolic exercise.

Consider Aβ because the mind’s try to guard its most lively areas from harm. Nonetheless, this safety seems to have its limits. In particular person mind areas of Alzheimer’s illness sufferers, increased Aβ ranges corresponded with decrease glucose metabolism, suggesting that extra Aβ accumulation might in the end impair regular mind perform.

This twin nature of Aβ—protecting initially however doubtlessly dangerous in extra—might clarify why Alzheimer’s therapies aimed toward eradicating Aβ have been largely unsuccessful.⁵

Nonetheless, the FDA continues to approve dangerous Alzheimer’s medication, together with Leqembi, which binds to amyloid beta within the mind. Counting on medication to scale back amyloid beta is misguided at finest and, at worst, exposes sufferers to doubtlessly life-threatening unintended effects with none profit. Alzheimer’s illness is a fancy illness that requires a holistic method to prevention and remedy.

Tau and Aβ don’t look like the first causes of neurodegeneration, however relatively the mind’s response to potential harm. Tau protein, specifically, is related to stabilizing microtubules in neurons and should play a job in defending in opposition to oxidative stress. Likewise, Aβ acts as an antioxidant, serving to to seal broken blood vessels.

Your mind produces these proteins as a protection mechanism, however when the underlying reason for the harm persists, their accumulation turns into extreme and doubtlessly dangerous. This shift in perspective emphasizes the significance of addressing underlying causes reminiscent of metabolic dysfunction and irritation, relatively than specializing in elimination of tau and Aβ.

How seed oils and endotoxins contribute to Alzheimer’s illness

A thriving intestine ecosystem is important to your total well being, together with mind perform. This various microbial neighborhood performs an important position in defending you from quite a lot of illnesses, together with Alzheimer’s illness, however is wealthy in polyunsaturated fat (PUFA), together with these present in seed oils. A food regimen containing oleic acid can disrupt your intestine well being, resulting in a number of dangerous results. Bioenergy researcher Georgi Dinkov explains:⁶

“this [Nature Neuroscience] examine⁷ Consider the ROS seen in AD [Alzheimer’s disease] Could also be attributable to extreme lipid accumulation (as in diabetes), which itself (even domestically within the mind) can simply be attributable to a low-carb/high-fat food regimen.

Cultivating helpful, oxygen-intolerant micro organism within the intestine, together with essential species reminiscent of Akkermansia, strengthens intestine defenses and promotes total well being. These helpful micro organism ferment dietary fiber to provide short-chain fatty acids (SCFA), particularly butyrate.

Notably, butyrate-producing micro organism reminiscent of Eubacterium and Essenbergia have been linked to a diminished danger of Alzheimer’s illness.⁸ Butyrate nourishes colon epithelial cells and strengthens the intestinal barrier. SCFA additionally stimulates the manufacturing of mucin, which varieties a protecting barrier in opposition to dangerous micro organism.

Risks of Leaky Intestine and Endotoxemia

The discount in oxygen-intolerant micro organism can result in elevated intestinal permeability or leaky intestine. This permits toxins, undigested meals particles, and dangerous microorganisms to enter your bloodstream, inflicting irritation and continual well being issues all through the physique. This irritation might trigger underlying harm that promotes the protecting accumulation of Aβ and tau proteins within the mind. Oxygen-intolerant micro organism are important for changing indigestible plant fibers into helpful fat.

They thrive in an oxygen-free surroundings and require satisfactory mobile power to keep up. Nonetheless, components reminiscent of seed oil consumption and publicity to endocrine disrupting chemical substances (EDCs) and electromagnetic fields (EMFs) in plastics can impair this power manufacturing, making it troublesome to keep up a super anaerobic intestinal surroundings.

Moreover, the poisonous lipids that tau helps neutralize are sometimes byproducts of extreme PUFA consumption and publicity to endotoxins. These components set off continual irritation and oxidative stress within the mind, resulting in the cognitive decline related to Alzheimer’s illness.

In my view, endotoxemia resulting in septic shock is the main reason for demise, if not the primary trigger. This occurs once you secrete endotoxins from facultative anaerobes (additionally known as cardio micro organism), that are micro organism that should not be in your intestine. These pathogenic micro organism produce a extremely virulent endotoxin or lipopolysaccharide (LPS) that may trigger irritation in the event that they cross the broken intestinal barrier and enter the systemic circulation.

I’ll introduce a brand new easy time period into the vocabulary to establish this idea, “Mighty Shock”. Mighty is brief for mitochondria and describes the goal of endotoxin, the mitochondria. The rationale endotoxin launch is so harmful is that it poisons and shuts down the mitochondria. I will be masking this subject extra sooner or later, so get able to learn extra about Mighty Shock.

As mentioned in earlier research, this continual low-grade irritation contributes to metabolic dysfunction that precedes Aβ accumulation in Alzheimer’s illness. Due to this fact, leaky intestine or a disturbed microbiome is without doubt one of the root causes of all illnesses, together with neurodegenerative illnesses reminiscent of Alzheimer’s illness.

Enhancing mitochondrial perform and sustaining a wholesome intestine ecosystem promotes the expansion of helpful micro organism whereas decreasing dangerous endotoxin results. This method mitigates components that contribute to dementia and different continual illnesses by addressing the basis causes of irritation and metabolic dysfunction, relatively than specializing in the elimination of Aβ and tau proteins.

A holistic method to mind well being

Understanding the protecting position of Aβ and tau proteins and the significance of intestinal well being opens new avenues for the prevention and remedy of Alzheimer’s illness. Somewhat than concentrating on these proteins instantly, future therapies might deal with supporting the mind’s pure protecting mechanisms whereas addressing the underlying causes of neurodegeneration.

This consists of methods to scale back irritation and optimize mind metabolism by intestine well being interventions. By cultivating a wholesome intestine microbiome and addressing components that disrupt the steadiness of oxygen-intolerant and antioxidant micro organism, you could possibly keep the protecting results of Aβ and tau whereas stopping their extreme accumulation.

With this new understanding, you may take proactive steps to assist your mind well being and scale back your danger of Alzheimer’s illness. By taking a holistic method to mind well being that addresses these underlying components, you may assist your mind’s pure protecting mechanisms and keep cognitive perform as you age. Along with optimizing mitochondrial perform, the next methods can also assist scale back the danger of Alzheimer’s illness.
