2. Marginal zinc deficiency: approximately 2 billion people worldwide suffer dietary zinc deficiency. It is now acknowledged that milder zinc deficiency causes some health problems, particularly in children who are living in developing countries. The experimental studies proved the role of zinc supplementation to treat marginal zinc deficiency that causes general weakness and impaired growth in children.
• Risk Factors:
Some people are at higher risk factors to zinc deficiency, these include people with malnutrition, vegetarian diet, gastrointestinal diseases, chronic liver disease, chronic kidney disease, alcoholism, sickle cell disease, diabetes, pregnancy and breast-feeding, or people takes high amounts of iron supplementation.
• Toxicity

-Predispositions include being born with jaundice, low vitamin D levels, and early exposure to cow’s milk (Morahan).
Vitamin B12 deficiency limits selenium methylation and excretion resulting in higher tissue selenium levels and subsequent toxicity. It occurs in people whose digestive systems do not adequately absorb the vitamin from the foods they eat. Vegetarians who eat eggs and milk products are the most at risk because, on average, they consume less than half the adult vitamin B12 Recommended Dietary Allowance (RDA) while strict vegans (who don't eat any animal products, including meat, eggs, or milk) are at an even greater risk. Vitamin B12 is important since it works with the vitamin folate to make the body’s genetic material and help keep levels of the amino acid homocysteine in check which helps to decrease heart disease risk. It is also essential in the production of red blood cells which carry oxygen through the blood to the body’s tissues. Life Extension gives offers some of selenium supplements. Babies who are born of parents with low selenium and vitamin B12 rich foods are at risk of anaemia.
Other diseases include a hearing loss, coronary heart disease, HIV and AIDS, kidney failure, and male infertility. Still other diseases include tinnitus, hepatitis C, pre-eclampsia, obesity, cholesterol and muscular
According to recent statistics, zinc is the third most commonly used nonferrous metal in the United States. This unassuming metal was among the first minerals exploited by Man, used as a decorative material for thousands of years, although it never achieved the fame and notoriety of other metals such as gold or silver. In more recent times, new extraction and processing methods have allowed Man to produce higher-quality zinc than ever before, and to use it in an astonishingly high number of chemical and high-tech applications.
Vitamin B12 is a powerhouse, it helps make DNA, nerve and blood cells and is crucial for a healthy brain and immune system. It is estimated that up to 15% of people don't get enough of this essential nutrient.
Dietary supplements are very beneficial to one’s body if they are taken correctly. There are many pros and cons to taking dietary supplements. In this paper I will discuss the pros and cons and how supplements affect the human body. We will also consider the government’s guidelines regarding dietary supplements.
There are many causes of anemia in the body. Some factors include genetics and deficiencies in the diet. Ms. A claims that for the past 10 – 12 years menorrhagia and dysmenorrheal have been a problem for her. Menorrhagia is abnormal and heavy menstrual bleeding during menstruation (Mayoclinic, 2013). Menorrhagia can deplete iron levels in the blood and increase the risk of an individual to have iron deficiency anemia. This is the cause of Ms. A’s anemia. Moreover, Ms. A says that she constantly takes aspirin especially in the summer to prevent stiffness in the joints. Aspirin affects and hinders the production of red blood cells (Mayoclinic, 2013). From the description of anemia given above, the lack of red blood cells, leads to low levels of iron and therefore low levels of hemoglobin which in turn affects the transportation of oxygen and thereby causing shortness of breath. Ms. A’s initial complains of shortness of breath and fatigue is the reason why she went to see the physician.
When one hears the three words: vitamins, nutrients, and minerals, they think of one thing-being healthy and noticing what your intake is daily. Nutrition is all about vitamins and nutrients. Firstly, vitamins are an organic compound required by the body in small amounts of metabolism, to protect health, and for proper growth of children. Vitamins also assist in the formation of hormones, blood cells, nervous systems chemicals, and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified vitamins are: A, D, E, and K-fat contained foods, B, C-consumed immediately. A well known and commonly used in commercials for orange juice vitamin is vitamin C. Vitamin C or ascorbic acid is important in the synthesis and maintenance of connective tissues. The lack of vitamin C will result in a sickness called scurvy. Scurvy harms the gums, mucous membranes, and the skin. Another well-known vitamin and is also used to commercial to give more information about this beverage is the vitamin in milk. The vitamin in milk is vitamin D. If you do not drink milk and obtain this vitamin, your bones and teeth will become soft and weak. Lacking one or more of the 13 well-identified vitamins will cause sickness and weakness to your body. Secondly, nutrients are how the body assimilates certain compounds. Nutrients are classified in 5 major groups: proteins, carbohydrates, fats, vitamins, and minerals. One of the five nutrients is carbohydrate. The carbohydrate group principally consists of sugar, starch, dextrin, cellulose, and glycogen. In more basic terms, carbohydrates are sugars needed by human and other living organisms. Some types of foods that contain carbohydrates would be candies, ice cream, fruit juice, soda, chocolate bars etc. Lastly, vitamins are connected to minerals. Minerals are also a very important part of a healthy person. There are 11 major groups of minerals. They are: calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. All these terms look very familiar if one has taken chemistry. These are the elements of our world. One of the more common minerals that most people have heard of is calcium. Calcium also helps with the structure and strength of teeth and bones. Vitamins and minerals work together to help humans maintain a healthy body. For example, vitamin D works with calcium to help for and maintain the strength of teeth and bones.
Vitamin, any of the organic compounds required by the body in small amounts for metabolism, to protect health, and for proper growth in children. Vitamins also assist in the formation of hormones, blood cells, nervous-system chemicals, and genetic material. The various vitamins are not chemically related, and most differ in their physiological actions. They generally act as catalysts, combining with proteins to create metabolically active enzymes that in turn produce hundreds of important chemical reactions throughout the body. Without vitamins, many of these reactions would slow down or cease. The intricate ways in which vitamins act on the body, however, are still far from clear.
Iron is a mineral that is found the in hemoglobin of the Red Blood Cells. It facilitates in the transport of oxygen all over the body. Without this mineral, oxygen cannot be carried to its full capacity. 1 out of 10 women and small children have iron deficiencies. Lacking iron causes lethargy and a weakened immune system. Children who do not have an adequate intake of iron put themselves at risk for intellectual developmental problems. However, an iron deficient person is not necessarily anemic. 7.8 million women are iron deficient, while only 3.3 million women are anemic (http://www.mayohealth.org/mayo/9704/iron_def.htm). When the deficiency becomes so severe that the circulating Red Blood Count and the minerals Ht, Hg, and Hem drop below normal, anemia occurs (See Figure 1). The hormone androgen causes men and women to have different normal values of the hemogram (http://www.medstudents.com.br/hemat/hemat4.htm). Low ferritin (iron storage molecule) and high TIBC (tota...
Obtaining Zinc Oxide from Calamine Introduction Calamine is a mineral containing zinc carbonate (ZnCO₃) On heating it decomposes as: [IMAGE]ZnCO₃ ZnO + CO₂ (C = 12, 0 = 16, Zn = 65) This equation allows you to calculate a theoretical conversion of calamine into zinc oxide. As when using the theoretical conversion; [IMAGE]ZnCO₃ ZnO + CO₂ [IMAGE]65+12+48 65+16 + 12+32 [IMAGE]125 81 + 44 This means that one mole of calamine weighs 125g and when heated it produces 81g of zinc oxide and 44g of carbon dioxide. Therefore to work out how much zinc oxide is produced from 1g of calamine we divide 81 by 125.
The third is not a myth, it’s a fact, and it states that Zinc can help cure the common cold.. “A review of the research by the nonprofit Cochrane collaboration found that zinc lozenges or syrup shorten the duration of cold by day if the zinc was taken within 24 hours of the first cold symptom, however, zinc can actually impair the immune system are taken in high doses.” Cochrane collaboration advises to take 75 mg of zinc on the first day of cold with caution. They warn people to stay away from zinc nasal sprays, in which, they can cause permanent anosmia Which is a permanent loss of smell. Airborne and other formulas that contain a mismatch of vitamins and minerals that were once purported to cure a cold. No evidence supports that these formulas
Holistic nutrition is increasingly becoming popular in healthcare practice due to the growing detoxification culture amongst the people with the aim of improving individual health. Consumption of toxic elements toxifies the body, the consumption of processed food products is the primary cause of diseases amongst the people. There is increased use of Holistic Nutrition by both healthy people and people with health conditions with the aim of achieving optimum body function and health. The increased use of holistic nutrition in the community improves health outcomes and reduces poor health outcomes that are caused by poor lifestyle choices of using processed food products. Holistic nutrition provides a natural approach of ensuring positive health
Zinc is an essential trace element for many living organisms. While this can be said about other essential metals, zinc is unique in its physiochemical properties that give it the ability to interact with donor groups of different ligands, resulting in a broad range of stability constants and diversity of the biological functions and processes that zinc is involved in. It was discovered and recognized as a new metal in the eightieth century, While its biological essentiality was found by Raulin for the growth of Aspergillus niger In 1869 [1]. In 1933 Zinc was found essential for the growth of animals while studying its effect on rats. [2]
