The Zinc Connection
The role of zinc was discovered in the 1950s by Henry Peters, a
porphyrinologist at the University of Wisconsin Medical School. Like
Morton after him, Peters was impressed by the number of people who seemed
to have mild or latent porphyria, and thought the trait was far more prevalent
that was commonly believed.
Peters discovered that his porphyria patients who had neurological
symptoms were excreting very large amounts of zinc in their urine—up to 36
times normal. In fact, their symptoms correlated better with the levels of zinc
in their urine than with the levels of porphyrins they were excreting. With
this information, Peters did the most logical thing: in scores of patients, he
tried chelation to reduce the body’s load of zinc, and it worked! In patient
after patient, when courses of treatment with BAL or EDTA had reduced the
level of zinc in their urine to normal, their illness resolved, and the patient
remained symptom-free for up to several years. Contrary to conventional
wisdom, which assumes that zinc deficiency is common and should be
supplemented, Peters’ patients, because of their genetics and their polluted
environment, were actually zinc-poisoned—as at least five to ten percent of
the population, with hidden porphyria, may also be.
For the next forty years Peters found tremendous resistance to his idea
that zinc toxicity was at all common, but growing evidence is now accumulating that this is so. Large amounts of zinc are in fact entering our
environment, our homes, and our bodies from industrial processes,
galvanized metals, and even the fillings in our teeth. Zinc is in denture cream
and in motor oil. There is so much zinc in automobile tires that their constant
erosion makes zinc one of the main components of road dust—which washes
into our streams, rivers, and reservoirs, eventually getting into our drinking
water. Wondering whether this was perhaps poisoning us all, a group of
scientists from Brookhaven National Laboratory, the United States
Geological Survey, and several universities raised rats on water
supplemented with a low level of zinc. By three months of age, the rats
already had memory deficits. By nine months of age, they had elevated levels
of zinc in their brains. In a human experiment, pregnant women in a slum
area of Bangladesh were given 30 milligrams of zinc daily, in the expectation
that this would benefit the mental development and motor skills of their
babies. The researchers found just the opposite. In a companion experiment,
a group of Bangladeshi infants were given 5 milligrams of zinc daily for five
months, with the same surprising result: the supplemented infants scored
more poorly on standard tests of mental development. And a growing body
of literature shows that zinc supplements worsen Alzheimer’s disease, and
that chelation therapy to reduce zinc improves cognitive functioning in
Alzheimer’s patients. An Australian team who examined autopsy specimens
found that Alzheimer’s patients had double the amount of zinc in their brains
as people without Alzheimer’s, and that the more severe the dementia, the
higher the zinc levels.
Nutritionists have long been misled by using blood tests to judge the
body’s stores of zinc; scientists are finding out that blood levels are not
reliable, and that unless you are severely malnourished there is no relation
between the amount of zinc in your diet and the level of zinc in your blood.
In some neurological diseases, including Alzheimer’s disease, it is common
to have high levels of zinc in the brain while having normal or low levels of
zinc in the blood. In a number of diseases including diabetes and cancer,
urinary zinc is high while blood zinc is low. It appears that the kidneys
respond to the body’s total load of zinc, and not to the levels in the blood, so
that blood levels can become low, not because of a zinc deficiency but because the body is overloaded with zinc and the kidneys are removing it
from the blood as fast as they can. It also appears to be much more difficult
than we used to think for people to become deficient by eating a zinc-poor
diet; the body is amazingly capable of compensating for even extremely low
levels of dietary zinc by increasing intestinal absorption and decreasing
excretion through urine, stool, and skin. While the recommended dietary
allowance for adult males is 11 milligrams per day, a man can take in as little
as 1.4 milligrams of zinc a day and still maintain homeostasis and normal
levels of zinc in the blood and tissues. But a person who increases his or her
daily intake beyond 20 milligrams may risk toxic effects in the long term.

Welp. Confirms again why I refuse to supplement metals (even iron fortified grains). I remember when zinc was a big deal in warding off colds and I would suck on one of those zinc lozenges when I was getting sick. Well it happened twice that I became MORE sick! like 101 fever with just a cold. Rarely get sick now with my current diet and no supps other than 200 mg vit C.

Yeah avoid zinc as much as possible, so your metallothionein goes down and you become toxic in all those toxic metals that will gladly take the spot where zinc should be.. Zinc toxicity is possible for sure. If you supplement like crazy or you work with it in factory etc.. But the idea that average person is most likely zinc toxic is hilarious. That person who wrote that obviously didn't spend many decades of study and testing people and their elements and how they interact with each other etc.. As Paul Eck and others did. Zinc is metal that is the most easily lost from our body simply by urine or sweat. Now go and do some research how "easy" it is to eliminate toxic metals that have no use in our body. Basically you slowly keep accumulating them as the ability of your body to detox is going down. We all have those toxic metals so it is about ratios. I would rather have more zinc that is used in our body for so many essential things than to be loaded with stuff like mercury, lead, cadmium etc. that just basically creates chaos and speeds up aging.

If someone should or shouldn't supplement depends on his diet. If person eats animal foods like sea food and meat he should be ok. But if the person is vegan or vegetarian for example we know that those kind of diets are not great for saturating the body with zinc and most importantly keeping healthy zinc:copper ratio.

I don't eat red meat for now due to having higher iron than is ideal so I take something like 15mg of zinc.

With zinc taking even higher doses of zinc lets say up to 100mg it is not about issues from zinc toxicity itself, but about issues from lowering copper to much.. Copper is one of those problematic metals that zinc is keeping under control, but in comparison with other heavy metals we need copper.. That is basically the only concern while you are taking zinc. That you deplete copper and that is bad news...

To give you idea how safe zinc is. Jacob that created HG7 protocol is taking like 200mg of zinc for how long 5 years? What is the most impressive is that he doesn't show any signs of copper deficiency. In comparison basically all promoters of copper look copper deficient. White/grey hair, pale/red skin with no healthy sigh of melanin production etc..

The only time I got a hair test (the right lab of course) back in 2015 my zinc was in good range. I thought to myself I don't even supplement and clearly my diet is providing enough. That was when I had almost got done breastfeeding for many yrs and was also consuming gobs of sugar on the Ray Peat diet.

I know you are using irony here, but so you think she took some zinc lozenges and got zinc toxic? Heh..

Not to mention getting strong fever is actually good sign of robust immune system function. I didn't have fever for decade + while I was completely crashed with very low white blood cells etc..

I would think people here are more aware of the fact that if you are not getting sick with fever here and there it is actually not a good sign..

Healthy person with healthy immune system actually gets strong fever in those hardest months of the year as the body is cleansing the body from all kinds of pathogens. It is strong and short. That is how healthy body should react.

When I hear someone saying "I was not sick for 20 years" all I can think of that that person is heading to learn that he has some serious issues like cancer or something..

If anything people should even mimic fever with using sauna. That's why heat therapy is so good for you. It activates immune system and all enzymes in the body speed up..

Healthy person with healthy immune system actually gets strong fever in those hardest months of the year as the body is cleansing the body from all kinds of pathogens. It is strong and short. That is how healthy body should react.

When I hear someone saying "I was not sick for 20 years" all I can think of that that person is heading to learn that he has some serious issues like cancer or something..

If anything people should even mimic fever with using sauna. That's why heat therapy is so good for you. It activates immune system and all enzymes in the body speed up..

I actually believed this! The only time I've had a cold since doing the beans was right after being exposed to bleach fumes. Now I'm not so sure colds/flus are a sign of a healthy immune system, or maybe just a sign of a toxic environment. My white blood cells are lower, but not too low still in range. But I will continue to make sure my lack of colds is a sign of health and not cancer. I do still believe someone who is clearly not healthy not getting sick ever is a sign of impending doom. Also forgot to add my husband also hasn't been sick since we cleaned up our diet.

Welp. Confirms again why I refuse to supplement metals (even iron fortified grains). I remember when zinc was a big deal in warding off colds and I would suck on one of those zinc lozenges when I was getting sick. Well it happened twice that I became MORE sick! like 101 fever with just a cold. Rarely get sick now with my current diet and no supps other than 200 mg vit C.

You were just dumping copper silly.

I know you are using irony here, but so you think she took some zinc lozenges and got zinc toxic? Heh..
