...Antioxidants, Bone Health, and Metabolic Process in Bodybuilding Antioxidants are molecules that inhibit the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons and hydrogen from a substance to an oxidizing agent. Oxidation reactions can produce free radicals and in turn, these radicals can start negative chain reactions. When these chain reactions occur in cells they can cause damage to the cell’s DNA that in turn causes muscle, joint, and tendon damage and inflammation. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. Antioxidants such as vitamin C and E can play an important role in reducing inflammation, fatigue, tissue damage, and both prevent and treat injuries. This can play a major role when trying to gain muscle mass due to the fact that your muscles break down when working out. Antioxidants are a vital supplement for athletes as well as body builders. When you exercise heavily in any form, your body actually produces free radicals because your energy systems and metabolism are working at such a high capacity. Taking antioxidant supplements daily can reduce the chances of these free radicals harming your cell production and tissue growth and repair. One of the most important antioxidants that athletes as well as the general public should consume daily is Vitamin C. Your body uses large amounts of vitamin C to fight off infections, colds, and disease and other healing...

...The purpose of calcium and phosphorus in the body is to build bones and teeth and give rigidity to the structures. Bone is continually being built with new bone being formed, whilst this also happens to teeth, it is at a much slower rate. Calcium circulates the body in the blood and appears in other body tissues where it helps blood to clot, muscles to contract and nerves to transmit impulses. A major source of calcium is from milk and to a lesser extent, milk products. Without milk or milk products in a diet, it can be difficult to get enough calcium. Other good sources of calcium include tinned salmon and sardines which include the bones and several greens such as broccoli, mustard greens and turnip greens. People who have a vegan diet are also able to source calcium from calcium-set...

...cations are positively charged and Ions that move to the positive which are called anions are negatively charged. They can be divided into acids, bases, and salts, because they all give ions when dissolved in water. Electrolytes are present in the human body, and the balance of the electrolytes in our bodies is essential for normal function of our cells and our organs. Electrolytes are important because they are what your cells, especially nerve, heart and muscle use to maintain voltages across their cell membranes and to carry electrical impulses such as nerve impulses and muscle contractions across themselves and to other cells. The major electrolytes that are in our body are as follows: sodium (Na+), potassium (K+), chloride (Cl-), calcium (Ca2+), magnesium (Mg2+), bicarbonate (HCO3-), phosphate (PO42-), sulfate (SO42-). Sodium is an abundant metallic element which is an important mineral for all living organisms. It is also widely used industrially to make an assortment of consumer goods. In a pure form, sodium is a soft, silvery gray, highly reactive metal. Pure sodium is usually stored in a nonreactive substance, as it oxidizes rapidly when exposed to air, quickly forming a thick coating. The soft metal appears in an abundance of compounds, such as sodium chloride, better known as salt. It also exists in high concentrations in seawater, and it is among the 10 most abundant minerals in the Earth's crust. The chemical element of sodium is also highly explosive when exposed...

...amounts of calcium and vitamin D to preserve bone strength and ensure overall maintenance of bone health to prevent osteoporosis. F. Cosman (2014) states that the human skeleton contains 99 % of the body’s calcium stores, and when the supply is insufficient, bone tissue is reabsorbed from the skeleton to maintain the serum calcium at a constant level. This process creates fragility in the bone structure and one may be at greater risk of developing osteoporosis. Since vitamin D plays a major role in calcium absorption, it is essential to ensure adequate amounts are being received. According to F. Cosman (2014), it is recommended that a male aged 50-70 consume 1000 mg/day of calcium, a female 51 and older, and males 71 and older, consume 1200 mg/day of calcium to maintain bone strength. In turn, an intake of 800 to 1000 international units (IU) of vitamin D is recommended for all adults aged 50 and older in order to ensure proper calcium absorption. This intervention is relevant to osteoporosis as the focus is to maintain a chemical balance within the body to promote bone strength. This ensures proper absorption and reabsorption within the body and thus one can avoid and prevent bone degeneration. However, ingesting more than the recommended amount of calcium may lead to other health issues such as stroke, cardiovascular disease, or kidney stones. This multidisciplinary panel of experts provides extensive research on the adequate intake of both vitamin D and calcium and the benefits...

...Tiffany Finger Perio II 9.23.13 Be strong- Choose Calcium Phosphate When one thinks about it, what are the natural building blocks of teeth? The answer is simple: calcium and phosphate! Combined, these materials are much like bone in composition and range in different forms used in dentistry, such as cements, coatings, tooth replacement, and composites. Because teeth require much force and strength, calcium phosphate is an excellent choice because of it’s nontoxicity and biocompatability. Calcium phosphate can benefit nearly any patient experiencing discomfort in the oral cavity, and our role ad dental hygientists are here to help! The overall pH level of one’s oral cavity can effect bacteria mechanism in many ways. Once the pH level drops below 5.5, demineralization occurs, reculting in loss of calcium and phosphate. In this case, Fluoride suppliments are a good recommendation to help with the remineralization phase. Because Fluoride contains calcium phosphate, it collects on the enamel of the tooth, building a layer that makes the tooth more acid-resistant. This will help aid in less bacteria formation, which can overall decrease caries. Calcium Sodium Phosphate (CSP)is a mixture of compounds known to help with dental hypersensitivity, including toothpastes, desensitizing toothpastes, prophy paste, and air polishing powder. When exposed to saliva, the sodium helps resist acid, while in time the calcium and phosphate assist in remineralization. Most of the products...

...Osteomalacia, a metabolic disease of calcium and phosphate 20 November 2015 Osteomalacia is decreased mineralisation of the bone caused by a deficiency of calcium serum in the blood, vitamin D, or a phosphorous deficiency. The body needs calcium serum for skeletal bone health as well as muscle and neuron action potential. Without enough calcium serum in the blood, the body responds by absorbing it from the small intestine, mobilizing calcium from the bones, and reabsorbing it from the kidneys (DeLuca, 2014). If the there is not enough calcium in the diet, the only source of calcium is the skeletal bones which leads to bone softening and weakening resulting in fragile bones prone to fractures. Osteomalacia can be indirectly caused...

...What is Osteoporosis? According the National Osteoporosis Society, in the UK population one in five men and one in two women over the age of 50, will sustain a bone fracture as a likely consequence of osteoporosis. Osteoporosis is a progressive disease which affects bone density and is characterised by the structure of the bone becoming more porous. Under a microscope osteoporotic bone is clearly identifiable, as it contains many more holes within the structure of the bone matrix compared to normal bone. This change in bone mass causes the bone to be structurally weaker and makes it more vulnerable to fracture. Ordinarily, healthy bone structure relies on two finely balanced processes of; bone formation and bone breakdown. In the case of osteoporosis, bone breakdown occurs more rapidly than bone formation, compromising both structure and strength. Furthermore the National Osteoporosis Society states that the daily cost of osteoporosis to the NHS is £6 million a day, with over one thousand deaths each month resulting from osteoporosis related hip fractures. These statistics are even more shocking when we consider that osteoporosis is largely a preventable disease. Symptoms and Diagnosis? Osteoporosis is problematic as it largely progresses in an asymptomatic manner, with diagnosis often not occurring until the point of the first fracture. At this stage the disease is well established and the bone density is already compromised. Commonly, fractures occur within the wrist (known...

...According to her blood chemistry test, her blood calcium level is 7.3 mg/dl. This means her calcium level is low than normal. This indicates that there was no calcium supplement found in her diet which lower the value of bone mineral density. This leads to the thinning of bone. If her test result would have been normal and she would have consumed more food that is rich with calcium, her bone would not have been fractured. The thinning of the bone takes place whenever there is low calcium level along with other factors listed above like Estrogen level, Vitamin D...

...Introduction Various factors influence body weight and composition, including energy balance, calories, nutritional makeup, and physical activity. Several tips are available for managing weight, including eating small, balanced and healthy meals, getting regular exercise, regulating meal sizes, and drinking enough water. In this assignment, I'll discuss the relationship between energy balance and body weight and the key strategies for promoting and sustaining weight loss at various intervention levels. I will next go over the distinctions between fat-soluble and water-soluble vitamins. I will next discuss how this classification affects how they are absorbed, stored, and used by the body. I'll explain the most significant food sources and the roles that vitamins play in antioxidants. Lastly, I'll review how mineral deficiencies impact public health and how certain minerals significantly impact quantifiable issues like anemia and bone disorders. 1- Explain how energy balance is related to body weight. What are the ways to promote weight loss and weight maintenance through various levels of intervention? Energy balance is the equilibrium between the body's energy and the energy it absorbs from food (Hill et al., 2013). Weight gain results from a positive energy balance, or when the body absorbs more energy than it uses. On the other hand, weight loss occurs if there is a negative energy balance, meaning that more energy is expended than is absorbed. A potent illustration of energy...

...provide a framework for the attachment of muscles and other tissues. Movement bones enable body movements by acting as levers and points of attachment for muscles. Protective, bones such as the skull and rib cage protect vital organs from injury. Bones also protect the marrow. Metabolic, mineral storage. Bones serve as a reservoir for calcium and phosphorus, essential minerals for various cellular activities throughout the body. Blood cell production. The production of blood cells, or hematopoietic, occurs in the red marrow found within the cavities of certain bones. Energy storage. Lipids (fats) stored in adipose cells of the yellow marrow serve as an energy reservoir. The whole package of bones, cartilage, ligaments, and tendons that make up the human skeletal system account for about 20 percent of our body weight — not much for the big job of keeping us moving and healthy. To ensure that your bones stay healthy, aim to consume at least 1,200mg of calcium every day. The best sources of calcium include milk, yogurt and cheese. Other good sources include broccoli, kale, canned salmon with the bones and calcium-fortified foods. Vitamins play a role in the management of the body's chemical reactions, which involve how the body uses food for energy, and how it maintains and regulates body tissue. Minerals function in the production of hormones, maintenance of regular heartbeat and bone formation. Vitamins and minerals differ in origin. Organic vitamins come from plants and animals...

...The average child spends six and a half hours a day at school, eight hours sleeping, a few hours of bus time, and an hour to get ready in the morning. This leaves children approximately four hours of time awake at home. So children are spending more time at school than home during the five day school week. With that in mind one would hope schools are providing a nutritionally, as well as educationally, sound environment for children to develop. Unfortunately, as long soft drinks are in schools they are not. Permitting soft drinks to be readily available to students is detrimental to their health in several areas of concern: growing obesity trends; weakening of the bones; and of course there are several other concerning area. Overall, the consumption of soft drinks should be limited by everyone, especially children, and the first place to start is by eliminating the option at school. Fizz Weight In today’s society one is fixated on bigger is better and moderation has lost its way. “During the past 40 years, the obesity rate for children ages 6 to 11 has more than quadrupled (from 4.2 percent to 17 percent). And for adolescents ages 12 to 19, it has more than tripled (from 4.6 percent to 17.6 percent)” (Keeping Kids Healthy). Soft drinks fall into the top of the food pyramid, which means they should be consumed very seldom. With moderation thrown out the window consumption of soft drinks are high and so are the obesity rates. The distribution of soft drinks in schools should...

...Food Studies Role of calcium reducing risk factors in the diet. Calcium is a vital nutrient mineral in the diet. Some of it’s many functions include, the formation of bones and teeth, helping our blood to clot and intracellular signalling in nerves and muscle. When we consume insufficient amounts of this nutrient we can encounter many risk factors such as Osteoporosis. O’berine of the National Dairy Council states that over 200 million people have osteoporosis worldwide. This includes one in four women and results in weak brittle bones which can fracture easily. The Recommended Dietary Allowances for Ireland in 1999 were 800 mg per day for adult men and women. This RDA remains the same today. NANs 2011 reports that Calcium intakes were below the EAR(estimated average requirements) in 16% of women aged 18-64 years. This would contribute to the one in four women being diagnosed with osteoporosis as their calcium levels are too low. American Bone Health (2011) states that 90% of our bone mass has been formed by the age of eighteen. This is reflected in the fact that the RDA of calcium for teenager is 1200mg. If we can encourage young people to increase their calcium intake before reaching their peak bone mass we can greatly decrease the risk factor of developing osteoporosis. The After peak bone mass is reached our bones gradually lose mass and if we did not consume enough calcium this can lead to porous fragile bones. Therefore it is vital to increase our calcium intake before...

...How to Strengthen Your Teeth and Gums A new discovery throws light on teeth collagen Collagen is a structural protein that forms the major component of the connective tissue and plays a significant role in forming bones and cartilage. Till now, it was believed that collagen was found only in these tissues, but recent discoveries state that this integral protein is also found in dental papilla, the flesh surrounding the teeth. The two types of collagen predominantly found in the papillae are type 1 and type 3 collagen. Type 1 and 5 collagen is found in the enamel of the teeth with type 3 collagen additionally found in tooth germ, the part that essentially forms into the new tooth material along with dental papilla.

...researchers collected blood and urine samples from the subjects. Subjects consuming HPHD diets showed adequate bone health after 16-weeks of monitored exercise evidence. In another study, researchers measured the plasma concentrations of insulin-like growth factor 1 (IGF-1). IGF-1 plays an important role in proper skeletal growth and development. Subjects consuming 42 g protein compared to the group consuming 70 g carbohydrate had an increase in plasma IGF-1 (P = 0.01). In another study, researchers measured calcium absorption by collecting blood and urine samples to assess the effects of the diet on biomarkers of bone metabolism. In this 15-week study, researchers discovered that a diet with high protein increased the absorption of dietary calcium and IGF-I by >20% compared to the low protein diet. In another study, participants were given either a 30g whey protein drink or a placebo of 2.1g protein drink over a 2-year period. DXA scans of hip areal bone mineral density and serum IGF-1 were measured. The increased protein intake did not have beneficial or deleterious effects on bone mass or strength. From the four studies reviewed, it appears that high protein consumption plays some role in bone structure, and has a particularly strong association with IGF-1. This has positive implications for high protein...
