zinc mines depletion


Zinc depletion is linked to histamine related itching, mast cells releasing more histamine into the bloodstream, and a whole host of other conditions. You'll notice from the featured photo that many high zinc foods are high histamine. Below you'll find a list of low/medium histamine foods. All references always at the bottom of the post.

2. Zinc. Zinc is an essential trace element important for many biochemical and physiological processes related to brain growth and function [11,12], as well as cellular metabolism [13,14].Zinc is acquired through dietary intake of foods such as red meat, oysters and crab, and zinc deficiency can occur with reduced intake, insufficient absorption, and/or increased zinc utilization or expenditure.

The zinc-extraction curve is the average of the two curves given above. Recycling of zinc follows a hyperbolic tangent curve from 31% to 50% recycling with a break point of year 2100 and width 10 years. The recycling is delayed by a Gaussian curve peaking at a delay of 10 years and a width of 5 years.

Mild deficiency that is not clinically overt may still cause nonspecific consequences, such as susceptibility to infection and poor growth. The plasma Zn concentration has poor sensitivity and specificity as a test of deficiency. Consequently, diagnosis of deficiency requires a combination of clinical assessment and biochemical tests.

Children aged 12 and older should take 30 mg of zinc picolinate, twice daily, with meals. Children aged 6 to 11 years can take 15 mg, twice daily, with meals. It can take three to four months for zinc supplementation to restore a normal copper-zinc balance. Once zinc-copper ratios have been balanced, medication is less likely to cause side effects.
