Introduction
During the past few hundred years, zinc has been known to be the vital mineral and catalytic of a lot of proteins and a signalling messenger who is released by neural activity. (choi & koh, 1998) Since zinc has been discovered by raulin in 1869 to be needed as a grower of aspergillus niger which is type of fungus and one of the most common species of the genus aspergillus, this fungus is common contaminant of food and cause black mould on certain food. Beside the cause of contaminated food, zinc has been admitted as important for human in modern times.(Prasad, 1984) (Hambidge , 2000) (Vallee & Auld, 1990)
Zinc is contained in most of food, especially fish and meat provides the most and optimum sources due to the

If in human body occurs zinc deficiency and toxicity, it will affect the growth, brain development, pregnancy and male reproduction and also will cause anorexia. Aside from the deficiency, if too much consume of zinc it will induce the toxicity. This research study will discuss further the deficiency and the toxicity of zinc in human body. (Brycesmith, 1989)
Food Source of Zinc
The distribution of zinc is widely and is typically associated with the protein fraction and/or nucleic fraction food. Meat (beef, Pork), poultry, organ meats (beef, poultry), fish and shellfish are rich sources of dietary zinc which also can be found in eggs, dairy product with lesser amount (shown in table below). Whole grain cereal especially bran and germ, nuts, seed also legumes have high zinc content, meanwhile tubers, refined cereals, fruits and vegetable have less. Comparing zinc absorption between animal source and plant origin on body animal source will have higher bioavailability then plant origin it because of the fiber and phytates that can inhibit the zinc uptake by intestine.

The interaction between zinc and cooper are equally opposed, both are being interacting in gastreointestinal uptake so it potencially leading to imbalance. It can be also applied for zinc and iron in competing on absorbtion, an
Magnesium and Zinc are tied at 33% DV. Both support healthy immune systems. Zinc is essential for DNA and protein synthesis; and accelerates wound healing. Magnesium is known as the anti-stress mineral and promotes a
Zinc is an essential mineral, it is either added or naturally present in foods. You can find since added in many cold lozenges and a few over the counter cold remedies. There are numerous aspects of cellular activity that zinc is apart of. A few examples would be protein synthesis, wound healing, DNA synthesis, and cell division. While Zinc can also support a normal growth and development for women during pregnancy, as well as a child and adolescence. A daily intake of zinc is needed in order to maintain since the body has no specialized zinc storage system. To determine the proper intake recommendations of Zinc, using the Dietary Reference Intakes can help determine the right amount.
The body also needs zinc to make proteins and DNA, the genetic material in all cells
Overpowering metals accumulate in the body, initiating various achievement issues and impacts all organs in the body.
Choose foods containing iron, zinc, iodine and calcium to support normal growth and development as well as to prevent deficiencies;
Zinc, in commerce also spelter, is a chemical element with symbol Zn and atomic number 30. It is the first element of group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: its ion is of similar size and its only common oxidation state is +2. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest mineable amounts are found in Australia, Asia, and the United States. Zinc production includes froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
The vegetables that I used were not only rich in vitamins but also in various minerals such as potassium, copper, maganese, magnesium, protein, Omega-3, phosphorus and iron. All vegetables contained potassium, which results that people consumig the meal get better liver, their muscles as well as their heart works better. Three of the vegetables that I chose to use contained copper, which is the key mineral in many different body systems. It is central to building strong tissue, maintaining blood volume, and producing energy in your cells. The three ingredients that were rich in copper were broccoli, haricots verts and
This experiment was carried out to understand how Gammarus are exposed to Zinc over a duration of 60minutes. The LC50 was calculated to understand if there is lethal concentration to 50% morality of organisms. In this experiment zinc was used as the toxic product and the organism used was Gammarus. LC50 values were at 45 minutes and 60 minutes. The LC50 value for 45 minutes was 36mg/L and the LC50 value for 60 minutes was 20mg/L.
A fifteen year old boy abruptly became ill; he experienced fatigue, headaches, tingling limbs, weakness, and weight loss. The only information provided stated that he had been using an acne cream prescribed by a dermatologist as well as an over the counter “beauty cream” to deal with skin irritation. The doctors could not find the reason for the boy’s illness, but interestingly a heavy metal was found in the boy’s urine. What could possibly be the heavy metal and could it have caused such a severe reaction? The objective was to find the cause behind the sudden sickness of this 15 year old boy.
Heavy metals are widely present in the environment and arise from either natural or man-made source. However, Human behavior coupled with the increasing technological advancement has resulted in increased production of waste products in unadulterated environments across the globe. Furthermore, these acts of environmental pollution could be either accidental or sometimes deliberate; nonetheless, more of these toxic heavy metals are finding their way into the food chain.
Magnesium: About 50 percent of the magnesium in the body is in the bones. Magnesium is a part of chlorophyll, the green pigment found in plants, so green leafy vegetables are one good source. The magnesium content of refined foods is usually low. Although magnesium is present in many foods, it usually occurs in small amounts.
The minerals worthy of attention in animal nutrition include calcium, sodium, phosphorous, magnesium, manganese, copper, iron, zinc, and cobalt. Minerals are required by animals in substantially less amounts than other nutrients. Minerals perform specific functions in the body and are added to feedstuff in scientifically predetermined quantities. Minerals help to ensure that animals have appropriate weight gain and good reproductive characteristics. For livestock feed, animals acquire some minerals from mineral and salt blocks that are left in the open for them to lick. Additions to feedstuff may include bone meal, calcium carbonate, limestone, and premixed supplements. (CHSAS, 2011; Damron, 2013)
Likewise, extracellular zinc can have drastic effects on invading microbes. Zinc is the second most abundant transition metal within vertebrate hosts, and has been suggested to interact with up to 10% of host proteins and is crucial for proper immune function (Andreini et al., 2006; Wintergerst et al., 2006). In Streptococcus pneumoniae, it has been suggested that extracellular zinc may outcompete manganese for uptake via the cell-surface lipoprotein Psa (Eijkelkamp,
Metal ions are essentially needed to perform a sequence of significant biological functioning in the brain, such as nerve transmission, oxygen transport, synthesis and metabolism of neurotransmitters. In recent years considerable attention has been paid to the role of transition metal ions such as Mn2+, Fe2+, Cu2+ and Zn2+ in the brain and their involvement in the neurodegenerative disorders1. Since the abnormal accumulation of these transition metal ions in the brain plays a crucial role in the pathological process such as protein aggregation and oxidative stress in the neurodegenerative disorders, which are characterized by the progressive loss of neuron structure and function which ultimately leads to neuronal death2-4.

Chickpea contain nutritionally important minerals whom bioavailability was reported to be good mainly for the iron. (H) Raw chickpea seeds provide about 5 mg/100g of Fe, 4.1 mg/100 g of Zn, 138 mg/100 g of Mg and 160 mg/100 g of Ca. About 100 g of chickpea seeds can cover the daily dietary needs of Fe and Zn and 200 g can meet that of Mg. The amount of total Fe present in chickpea has been reported to be lower than that in other pulse crops such as lentils and beans. Chickpea also contain other trace elements including Al, Cr, Ni, Pb and Cd with quantities that do not pose any toxicological
