Excerpt from the book:

Zinc (Zn)

Hair zinc does provide useful information about body zinc levels but interpretation can be complex since elevated hair zinc can indicate low body levels, and low zinc can too.

Low hair zinc does correlate well with low red blood cell and total body zinc.  Substantially elevated hair zinc is usually a sign of zinc wasting and consequent LOW body zinc levels (and low blood zinc levels).  That is, people with high hair zinc usually have low red blood cell zinc and low tissue levels of zinc.  Rarely  will high hair zinc be due to elevated body levels of zinc.

Plasma and serum zinc are reduced in acute illness and are not reliable indicators of body inventory.

...

Vegetarian diets are low in zinc.  High carbohydrate intake is believed to reduce zinc levels and high consumption of grains is known to hinder zinc absorption.  Modern foods are relatively low in zinc compared to foods 50 years or more ago (due to changes in agricultural methods since that time), and sometimes are preserved by the use of EDTAor other agents to sequester whatever zinc is in them and render it unavailable. In addition, zinc absorption from the intestines is limited and saturable, which means a smaller fraction is absorbed as the amount taken increases. Thus as you increase the amount taken a lot the amount absorbed only increases a little.  Because of this very few people will have high enough zinc levels to be a problem unless they take zinc supplements several times a day for months on end.

...

Much zinc is absorbed in the large intestine and people with chronic diarrhea can become zinc deficient.

The half life of zinc in the body is about 4 months.  Interventions to affect zinc levels will thus typically have their effects gradually over a period of several months.

...

Low zinc levels lead to rough dry flaky skin especially on the hands, feet and around body orifices.  It also causes slow wound healing, poor immune function – specifically cellular immunity – in the presence of normal levels of white blood cells and antibodies, poor appetite, reduced taste sensitivity, reduced sense of smell,  fatigue and poor night vision.  Low zinc also lead to impaired growth and development in children, and to birth defects and difficulties during labor and delivery.  Severe forms of childhood zinc deficiency are described in standard medical textbooks.  Current estimates are that about 10% of children have mild zinc deficiencies that they are suffering some negative effect from, e. g. that they have recurrent ear infections – a problem which can often be stopped with supplementary zinc.

...

Low zinc levels are known to cause impairment of neurological and psychiatric functioning which are corrected by zinc supplementation, and zinc supplementation is known to improve attention and behavior in ADHD.

The specific aberration of immune function that zinc deficiency causes is an imbalance between T helper type 1 and T helper type 2 cells along with reduced activity of natural killer (NK) cells. This is also commonly observed in mercury toxic people and is most likely a consequence of their poor zinc status due to mercury induced mineral transport derangement.  This results in allergies, autoimmunity and a poor immune response to pathogens like viruses, bacteria yeast and fungus.
