Zinc deficiency
* Most zinc deficiencies affect health
  - cause production
* Some zinc deficiencies lead to accumulation.
* Zinc deficiencies affect functions
* Zinc deficiencies are a problem in pecans in most of the state
  - common in Western states and result most often in decreased stem length
  - deficiency diseases
  - uncommon in Willamette Valley soils
  - can reduce semen volume and testosterone levels
* Zinc deficiencies cause production
  - reductions
  - look like iron deficiencies but the leaves are much smaller than normal
  - occur on several types of palm trees
* appears to cause a generalized increase in the chronic toxic effects of cadmium.
* can aggravate the effects of vitamin E deficiency.
* can also affect fruit shape
  - impair the body s ability to fight infection
  - be present in addition to iron chlorosis
* can cause a whole range of consequences
  - delayed growth and sexual maturity, and prolonged healing of wounds
  - low testosterone levels
  - misshapen nails
  - impair immunity
  - interfere with a plant's ability to reproduce
  - reduce appetite, and so can some wasting diseases, such as cancer
  - result in hypogonadal dwarfism in which there is arrested growth
  - show up with white or striped leaves
* causes a host of problems but is unusual on an American diet
  - leaf chlorosis and can easily be overcome by the use of zinc sulphate
  - skin rash, loss of appetite, loss of taste and impaired immunity
* develops in some patients with cirrhosis because the ability to retain zinc is lost.
* has a severe impact on human health.
* is also a very rare isolated nutritional finding.
* is associated with defective cellular immunity
  - high soil pH and high available phosphorus levels
  - called rosette
  - characterized by decreased testosterone levels and sperm counts
  - common due to depletion of our soil and losses associated with food processing
* is common in cirrhosis and has been involved in the altered nitrogen metabolism
  - spots where erosion or deep plowing has brought subsoil to the surface
  - especially common in children and women
  - most common in older people
  - much more common than most GPs realise
* is seen as a 'Z' bend in the newer leaves
  - by lack of height and weight
  - strongly related to anorexia nervosa
* leads to iron deficiency causing similar symptoms
  - testosterone reduction and reduces the lifespan of sperm
* makes one more easily get infections.
* means increased susceptibility to infections and viruses.
* occurs more frequently in cool weather during stand establishment
  - on corn in Ontario
* reduces the production of leptin, an important signaling molecule.
* restricts growth and normal development.
* shows early in the growth of plants
  - up as a yellowish blotch or mottle between leaf veins
* well-known complication of Crohn's disease.
+ Zinc, Uses, In biology: Chemical elements :: Transition metals
  * Humans need a little bit of zinc to help their body run well. If they do not get enough zinc in their food, they can get a mineral deficiency. Almost two billion people have a zinc deficiency. Zinc deficiency makes one more easily get infections. Some people say that when we get colds, we should take more zinc. Others say that zinc does not make a difference. There are medicines that one can use when they have a cold. People add tiny amounts of zinc compounds to vitamin pills and cereals to make sure that they get enough zinc. Most single-tablet vitamins have zinc in them.

Degenerative disease
* Most degenerative diseases begin with the failure of the cycling of oxidative phosphorylation
  - originate in the intestines
* are at epidemic levels.
* can be the end result.
* indicates a worsening of physical or mental qualities.
* occur as a result of the natural aging of the body tissues.
* take decades of bad eating habits to develop
