well well well here we go again with the zinc.
Your skin contains one fifth of your body's zinc supply. Rats and mice that are deficient in zinc develop a skin condition called keratogenesis that is very similar to human psoriasis (Hoffer and Walker, Orthomolecular Nutrition, p 156-157). Zinc deficiency in humans is the rule, not the exception. The US RDA for zinc is only 15 milligrams a day, and yet the average American takes in even less than that. (Williams, Nutrition and Diet Therapy, 7th ed., page 253) In spite of this, it is most uncommon to find either dietitians or doctors ever recommending a supplement of this mineral.
Research has shown that supplements of zinc are safe up to about 500 mg. daily. At that huge dose, over a period of weeks or months, a copper deficiency may develop. A more sensible daily dose of 50 mg to perhaps 100 mg may be maintained for as long as is desired. A good multiple vitamin along with this will provide some balancing copper, as will (believe it or not) the copper water pipes in your home.
The "amino acid chelated" form of zinc is better tolerated and better absorbed than zinc sulfate or other inorganic forms of the mineral.
i can't believe that 500mg number, that's nutty. yes i know, coming from me that's an odd thing to hear, but seriously i haven't seen that particular research...
this is interesting too - i remember i had a GI yeast infection when i was a tween, right around the time i had my first outbreak... interesting that there's also a zinc/leaky gut connection...
There is much anecdotal evidence that certain foods act as triggers to psoriasis. Glutens, red meats, dairy, and cultured foods can irritate the intestinal tract and perpetuate psoriasis outbreaks. Within the intestinal tract, bacteria and yeast help process our food. When yeast becomes excessive, it interferes with the body's ability to absorb vital nutrients, and cause a condition known as "leaky bowel" to occur. Toxins get into the body and trigger the immune system. A cleansing psoriasis diet can help remove the irritating foods from the bowels, allowing the body time to heal itself, and can also help to reduce the yeast, fungus or bacterial proliferation. So, is psoriasis an intestinal yeast infection, or a food allergy, or a nutritional deficiency, or a leaky bowel? The answers to those questions are still not determined scientifically. However, many people are controlling their psoriasis using the cleansing diet approach. Diet and the impact of certain foods on psoriasis is understudied. Combining therapies, (example: diet with homeopathic minerals, diet and herbs, omega oils with diet or herbs) is showing positive results in greater numbers of psoriasis patients. For example, homeopathic minerals, designed specifically for psoriasis (Vestalcare PsoriasisTablets) has been shown to benefit mild to moderate cases of psoriasis. When combined with a cleansing psoriasis diet, the benefits are increased.
there are some forums with sufferers saying their various topical zinc products are so-so to lame, with one person saying psoriasis has nothing to do with zinc but is a defect in keratinization (skin formation).. so i searched zinc deficiency and keratinization, and apparently zinc deficient rats get a proliferation of these membrane-coating granules, and what are they exactly?
The content of the granules spreads over the cell surfaces, and subsequently a thickened and coated cell envelope is formed that resists the action of keratinolytic agent. The membrane-coating granule is regarded as a specific differentiation product of the keratinizing epithelium.
i don't get it yet but that sounds a fair bit like a psoriasis plaque in the making. must be that keratogenesis from the first reference above...
well, i could read up on it more, but i think i'll just keep monitoring my zinc and see how the skin comes along.
this whole psoriasis deal is part of the picture that helped confirm my neuro's ms dx. the inflammatory nature and relationships to arthritis i suppose. stupid genes.
