Abstract This paper explains the importance of calcium in a child's diet and takes a look at the calcium intake and needs of children and adolescents. The paper summarizes a study on fracture rates vs. milk consumption, on adolescent bone mineral density and on calcium in vegan diets and then looks at dietary factors which affect calcium intake, absorption and calcium loss.
From the Paper "Calcium intake in children may be insufficient for their needs, as their bones are growing and a study by Goulding et al showed that children who avoided drinking cow's milk for prolonged periods and did not consume calcium-rich food substitutes had low bone mineral densities. Low bone density combined with a high body weight increases the risk of bone fractures during growth when children are more prone to such fractures. Optimal bone growth cannot take place without sufficient calcium intake and in the Western countries dairy products are..."

Abstract This paper describes the need and benefits of calcium in our lives and discusses the detrimental or negative effects of overusing calcium resources.
From the Paper "It is obvious, the impact that calcium compounds have on our world today. It goes without saying that our lives would be very different without them. They are an essential mineral to maintain health, and an important component of many things that we need to make our lives better.
However, all of this convenience is not without cost."
Abstract This paper presents a brief overview of the benefits of dietary supplementation, with a specific focus on calcium supplements. The writer takes a positive view of supplements, provided the supplementation takes into consideration the individual's biology and lifestyle needs. The author also recommends that the supplements are dispensed with clear labeling and in conjunction with a health professional.
From the Paper "Perhaps one of the reasons there is such confusion about the issue of supplementation is the broad, sweeping claims made by popular manufactures of supplements, which promise generic cure-alls rather than sound advice. Not every woman may need iron supplements, if she eats fortified grain cereals and eats red meat. The personal and inexact science of creating an ideal diet, tailored to the individual, must be communicated on supplement labels by law. The current nutritional labels that give guidelines for generic 2,000-calorie diets for daily requirements, regardless of age, background, lifestyle, and quite often gender, are often misleading."
Abstract In this article, the writer examines the use of steroids. The writer explains that steroids require a prescription from a doctor before purchase. The writer then describes the method of use of steroid medication. Further, the writer discusses the negative effects on the body of such steroid use.
From the Paper There are so many different anabolic steroids that have been devised however each requires a doctors' prescription to be dispensed by pharmacies. The anabolic steroids can be taken--entered in someone's body--in many ways such as orally, rubbing onto the skin in terms of creams and gels, and also injected. Just as diabetics using insulin, the medication has to be used in a circular motion around the body. For example, a person injects themselves in the abdominal area, left arm, right arm and back to the abdominal areas. In addition, the steroids have to be taken in multiple doses to gather the effects and it is very addictive. "Users also frequently combine several different types of steroids in a process known as stacking"."
Abstract An overview of anabolic steroids is presented in this paper. Firstly a brief history, followed by statistics for the people using them. The writer then examines why people take steroids and what the effects are for men and women separately. It concludes with the treatment for steroids.
From the Paper "Anabolic steroids is the familiar name for synthetic substances related to the male sex hormone. They promote the growth of skeletal muscle and the development of male characteristics. They have been around for decades, but in the last ten to fifteen years the research on the effects of this drug has increased. The side effects were not known when the drug first came out, but they are becoming more and more prevalent through recent research. Many new side effects are being discovered and it is likely many more side effects are yet to be discovered. Males and females have different side effects to deal with, but all of them are harmful. Anabolic steroids are a growing concern throughout the world (Yesalis, 68)."
Abstract This paper explains that steroids are a controlled substance, which can both help and harm the user. The author examines the current issue of anabolic steroid use among individuals seeking to use them as performance enhancers to improve athletic performance and physical appearance. The paper relates the history of steroid use, its prevalence among professional athlete, and the potential hazards to one's health.
From the Paper "Steroids are controlled substances. For that reason, there is a great potential danger in their use. It is quite common for individuals to become addicted to steroids and even suffer some serious side effects. Unfortunately, steroids have gained some notoriety in recent years because professional athletes use steroids to improve their performances and effectively cheat. Obviously, steroids should be banned from professional sports and the players strictly screened for possible use. However, steroids can have benefits and should be available to the general public, though in a controlled fashion."
Abstract This paper discusses the abuse of steroids in the athletic world and presents a strong argument against the use of steroids by young athletes or by athletes of any age. This paper emphasizes how these substances destroy young bodies and present a moral affront to the sporting ideal of fair play and competitive integrity.
From the Paper "The paper begins first by discussing what these drugs do to the bodies of individuals. Specifically, emphasis is placed upon their impact on vital organs and their impact upon reproductive capabilities. At the same time, space is devoted to detailing the short-term benefits or "boosts" which make steroid ingestion so desirable for many athletes. From there, the paper turns to the fairly ubiquitous abuse of steroids in America - a discussion which is important because it highlights just how many Americans are placing their lives and health at terrible risk in pursuit of a peculiar image or in pursuit of athletic glory. Not to be overlooked is the treatment of the steroid or drug problem in professional sports.
Abstract Osteoporosis has been estimated to afflict from five to twenty million people in the United States alone. It is the principal cause of skeletal fractures in the elderly. The paper shows that while consuming enough calcium is important, bone health is more than just a matter of getting enough calcium in your diet. The paper examines what medical science knows about calcium and bone, and what it does not know about the disease, and overall bone health. The paper addresses five areas: calcium and bone, calcium nutrition, illnesses caused by insufficient calcium, suggested calcium intakes and, lastly, osteoporosis and calcium.
From the Paper "Osteoporosis is a silent disease and there might not be symptoms until a bone breaks and the condition is recognized after the incident on x-rays. The first sign may be hip or low back pain, or painful swelling of a wrist after a fall. Persons who fall into the risk factor groups should do all they can to avoid these symptoms by eating well and exercising. It is best to prevent the disease by building sturdy bones in childhood, but there are other steps you can take. Your peak bone mass is reached during your twenties and thirties so get regular weight bearing exercise, such as walking. In addition, get plenty of calcium in your diet and if need be use supplements. The average American diet contains about five hundred milligrams a day, but one thousand milligrams a day is recommended and needed. Do not smoke, and drink alcohol only in moderation. If you are at risk of developing osteoporosis and are nearing menopause, talk with your doctor about estrogen or other hormone replacement therapies."
Abstract This paper examines how calcium is a crucial component of the function of the nervous, cardiac and musculoskeletal system and how there are often stresses on the calcium levels in the plasma as various systems require more calcium than normal. It focuses on the regulation of the total body calcium levels, the mechanisms and levels of complexity involved as well as touching on some of the clinical conditions that arise when this system does not function effectively.
From the Paper "The importance of the PTH secretion is evident in deficient systems. In hypoparathyroidism, not enough PTH is present to respond adequately to the fall in Ca. This tends to cause hypocalcaemic problems, including tetany. This is also true for pseudohypoparathyroidism, where there is a defect bin the PTH receptors, preventing the PTH from having an effect. There are also problems associated with excess PTH causing hypercalcaemia. These conditions include hyperparathyroidism arising from tumours that secrete excess PTH. These patients not only have hypercalcaemia, but often have osteoporosis, urinary stones and sluggish CNS."
Abstract This paper provides a literature review of calcium pumps in the body. It discusses the vital actions of calcium pumps and describes how they work. The paper also discusses the factors that effect the efficiency of calcium pumps and what causes their function to be reduced. The paper specifically focuses on age-related diseases and how they effect the efficiency of calcium pumps.

From the Paper "Calcium ions are released to allow muscles to contract and perform its vital functions in life. But these muscles must also relax and calcium pumps perform that balancing function. Studies conducted on newborns and their mothers have shown that optimally functioning calcium pumps reduced the occurrence of toxicity from lead and mercury. Calcium pumps, however, tend to become less efficient with age and disease. When one ages, his fuel and energy level decrease. Age-related diseases set in. Calcium pumps require optimal levels of fuel and energy to continue performing efficiently. Aging dents these levels. These calcium pumps also reach their maximum capacity with age. And poorly performing calcium pumps may contribute to disease through their failure to reduce calcium levels brought about by contractions. Cardiovascular disease, diabetes and cancer can develop as a consequence. A disturbance in the performance of calcium pumps, therefore, can result in any of these serious or fatal conditions."

From the Paper "Putnam discusses the dangers of using steroids but also presents the alternative view of some people who argue that performance-enhancing drugs should be permitted in sports. Supporters of steroid use in sports, although small in number, argue that athletes are fully entitled to seek competitive advantages over their opponents and use of steroid is akin to using better equipment, better coaches, or better training programs. They also contend that the harmful side effects of steroids have been exaggerated. The author sees a subtle trend of leniency towards drug use by sport authorities and believes that drug use in sports would continue as long as medical science makes such performance enhancing drugs available (pp. 124-126)."
Abstract This paper explains that steroid use has increased significantly in the past five years due to the increased competition in sports. The author points out that anabolic steroids enhance an athlete's overall performance; however, the consequences of using steroids are not worth the dangers to which athletes subject their bodies and integrity. The paper reports that steroid use in high school athletes is growing rapidly as young athletes see professionals as role models that are willing to risk their health by taking steroids to achieve athletic goals. The author relates that anabolic steroids are banned in all sports in the United States and most of the world; however, this has not stopped athletes from trying to receive a competitive edge via steroid use. The paper underscores that the reason many athletes are willing to do steroids is because of lack of tough penalties.
From the Paper "In many sports, such as Major League Baseball, athletes are allowed many strikes and receive fines for using steroids. The current first strike offense in baseball is The policy says that the penalty for a first positive test for steroids is "a 10-day suspension or up to a $10,000 fine", and there is no public identification of players who are fined rather than suspended. Baseball has said that first-time offenders would be publicly identified as having failed a test in addition to a suspension. In the NFL, steroid use is banned. Players are randomly tested, and those testing positive could face game suspensions."

Abstract This paper explains that calcium consumption is critical for proper nourishment and bone development in elementary school-age children. The author points out that promotion of the importance of calcium consumption in early elementary years is critical; school nutrition programs and parents are the most likely authority figures that influence children's nutritional habits at the elementary level. The paper presents a literature review, which concludes that school-based nutrition programs are the most effective in promoting milk consumption perceptions, followed by parental input and feedback.

Analysis/Literature Review
Conclusion
From the Paper "Calcium can be found in many green vegetables and fortified breads and cereals, but typically, elementary aged children resist consumption of sufficient quantities of such materials. Some studies have also indicated that minerals such as calcium and phosphorus are more likely to be absorbed from milk than other calcium alternatives. Later in life, adults are also more likely to drink milk than eat a variety of green leafy vegetables if they have been exposed to the nutritional benefits of milk consumption early in life. By including calcium consumption via milk drinking in school meals, scholastic nutritional programs have a mechanism for providing and promoting better health and wellness among students."
This paper examines the use of steroids in sports, while citing several cases in the areas of professional, college and high school athletics across the U.S.
Abstract This paper explores the issue of steroid use in sports which is not only a problem in the professional circuit, but has crept its way into high schools and colleges across the nation. The writer of this paper focuses on the use of steroids in these areas while examining the various solutions to this growing problem. This writer details the current professional sports climate which does little to help this situation. Kids see athletes as role models and when they see them using steroids, they perceive it as an endorsement. This paper defines steroids as a medicine synthesized to perform like human hormones, mostly testosterone and to a lesser extent human growth hormone. The writer discusses the current punishments for steroid use, which are lenient by expert standards. This paper examines the various efforts to stop the use of steroids in sports. The writer contends that the underlying path to stopping the use of steroids in sports will come when the young athletes are stopped and held accountable for their actions.

From the Paper "Currently the punishments for steroid use are lenient by expert standards. A professional baseball player has to be caught four times before anything serious happens to him. The first infraction can get a 10 day suspension, while subsequent uses can get up to a quarter of as season on the bench. This sends the message to young sports enthusiasts that the use of illegal steroids is not that big of an issue.
One of the first things that needs to be done to stop the use of steroids is to change the public perception of winning and the importance of doing so. As long as children and adults are being conditioned that winning at all costs is acceptable steroid use is going to be an issue in sports."
Abstract This paper discusses how research has shown that there is a direct correlation between bone condition in an individual's juvenile and mature years and subsequent susceptibility to osteoporosis-related fractures. In particular, the paper looks at how the interventions that are being investigated to reduce osteoporosis-related health risks and to improve general bone health is diet and supplements of vitamin D and calcium.

Conclusion
From the Paper "The focus on osteoporosis prevention in turn has improved market performance of foods. Klotter (2005) points out that among all nutrients, calcium is among the most advocated by retails products. These include not only dairy-related products but vegetables, fruits and exercise activities as well. Whereas there has been some counter-marketing against dairy products because of their fat content and fears of contamination from diseases in the 1990's, they have gained better regard in consideration of their value in preventing osteoporosis (Heaney et al, 2000). The opinion is one that Klotter (2005) also recognizes in the course of her study of the impact of initiatives against osteoporosis in health as well as industrial markets today."
