This system is in place to protect us against things like parasites and foreign toxins. It helps us eliminate them effectively before they cause even more damage.
The question is, what causes the increased production of these chemicals from these cells unnecessarily?
Why do some people’s immune cells release more of these mediators in response to things that are harmless like pollen?
#1 Gut health
Roughly 80% of your immune cells reside in the gut, and they are major players in your susceptibility to allergies.
Poor gut health can wreck your immune system's ability to properly deal with allergens in a few ways:
◈ Bad bacteria shift the balance of T cells away from an anti-inflammatory (regulatory) state to a pro-inflammatory one (Th2/Th17)
◈ Intestinal permeability exposes the immune system to more allergens by allowing "leakage"
◈ Inflammation / bacteria can stimulate innate lymphoid cells (ILC2 via IL-25, IL-33, TSLP), which activates eosinophils, mast cells and B cells to produce IgE
◈ The gut is the biggest source of histamine + serotonin in the entire body by far.
In fact, an animal study showed that you can literally give them allergies simply by giving them the gut bacteria of another animal who has allergies.
The animals with allergies mainly had higher endotoxin containing bacteria, which drive all sorts of inflammation in the gut and beyond.
Allergies start and end in the gut.
Butyrate has shown the ability to reduce allergies in experimental models.
⬩Less anaphylaxis
⬩Lower IgE
⬩More “tolerant” / anti-inflammatory immune cells
⬩Reduced mast cell degranulation - the release of histamine
Butyrate also:
⬩Seals up leaky gut
⬩Promotes T cells to differentiate into the regulatory type
Your gut produces lots of butyrate when it's healthy, and lacks it when it doesn't
In a clinical trial, a bifidobacterium probiotic reduced symptoms of:
⇨ Runny nose
⇨ Itchiness
⇨ Sneezing
⇨ Asthma
by supporting the conversion of T cells away from their allergenic phenotype.
In general, things that support gut health also are anti-allergy.
Optimizing gut health should be at the absolute top of your list when it comes to eliminating allergies.
Your immune cells are finely tuned. They can either be highly adaptive and calm, or highly reactive and inflammatory.
We have multiple nutrients that govern this balance.
◇ Vitamins A+D - metabolites of each act on the genetic level in immune cells.
◇ Vitamin C - works on epigenetic mechanisms to increase T regulatory cells, which resist inflammation
◇ Zinc - needed for various anti-inflammatory gene expression, inhibits NFκB (master inflammatory signal)
◇ Calcium - prevents intracellular calcium accumulation in mast cells, a primary trigger of their activation
◇ Glycine - works on glycine receptors to depolarize immune cells
are two of the primary chemicals released by mast cells and eosinophils to produce allergic symptoms.
They are both metabolites of the omega 6 linoleic acid, the fat most abundant in seed oils.
A high omega 6 / omega 3 ratio also predisposes to allergies, since this balance governs whether immune cells can actively resolve inflammation properly.
#8 Estrogen
Estrogen is known to promote mast cell degranulation, while progesterone prevents it.
ANOTHER one of the most impressive studies in recent memory found that the combination of NAC + Glycine has remarkable anti-aging effects in nearly every metric.
This doesn't necessarily mean that one has to take this much, since this was measuring a relatively short period of time on the elderly, so they were trying to up their stores rapidly.
Typically, a maintenance dose of NAC is 1.2-2.4g, and glycine 3-6g.
Basic labwork showed improvements with the supplement.
◇ ↓ BUN (blood urea nitrogen) - nitrogen waste / protein breakdown
◇ ↓ Creatinine - muscle protein breakdown marker
◇ ↑ Estimated GFR - measure of kidney filtration capacity
◇ ↓ Triglycerides - circulating fats
Magnesium has the ability to shrink arterial plaques, demonstrated by some incredible clinical trials.
(🧵1/8)
This first study came out in 2008.
They gave people magnesium citrate, just under 100 mg elemental magnesium per day.
This is a puny dose, magnesium RDA is 4X that and people often supplement even more than that.
These studies are all in hemodialysis patients, and that's mainly because these people develop heart disease at a much quicker rate due to toxin accumulation and altered mineral balance.
Magnesium reduced plaque burden within 2 months.
Carotid intima median thickness (cIMT) is the literal thickness of the inner part of the arteries. It's a direct measurement of plaque buildup.
This was decreased on both the left and right sides, while plaque sizes tended to INCREASE without it.
The narrative that most doctors / public health agencies say around this topic is that:
1. It's a small amount of aluminum, in comparison to how much we are exposed to through diet.
2. It stays at the injection site, never migrating to the brain or other tissues.
3. It gets filtered out by the kidneys nice and easy no problem
Unfortunately, these are all only half true, and experimental evidence shows that injected aluminum in low amounts can indeed cause problems.
A number of experiments have shown proven these claims to be shallow at best.
This study investigated low amounts of Alhydrogel, the aluminum based vaccine adjuvant (200, 400 and 800mcg Al/kg of body weight) via intramuscular injection.
They actually showed a selective negative effect at the LOWER dose.
◇ More brain accumulation
◇ Greater impairment in cognitive assessments
So the "low doses" argument becomes less relevant.
