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

Meats and grains are poor sources of calcium.
Adults only absorb about 30% of calcium, but during growth and pregnancy when additional calcium is needed about 60% is absorbed. Postmenopausal women tend to absorb the least amount of calcium and are at a high risk of developing osteoporosis. A lack of calcium in children can cause rickets. The recommended amount of calcium per day for adults is 700mg.
Vitamin D helps calcium be absorbed, while other substances such as the tannins in tea caffeine and large amounts of phytic acid, a binder found in wheat grain and whole grains, interfere with calcium absorption.
Phosphorus is involved in the release of energy from fat, protein and carbohydrates during metabolism, and in the formation of DNA and many enzymes. If functioning normally, the body acids and alkalis and this balance is vital. Phosphorus plays a major role in keeping this balance in place. Phosphorus is unlikely to be lacking because it is widely distributed in foods and milk products.
Fruits and vegetables are generally low in this mineral, however it can be easily found in meat, poultry, fish, eggs, legumes and whole-grain

Nutrition Analysis Essay

...Nutrition Analysis Essay- Vitamins and Minerals Vitamins and minerals are essential to optimal body function and the overall health of body cells. These two important nutrients are needed daily to keep the body functioning in several roles such as blood clotting. Vitamins are in two forms- fat soluble and water soluble. Lack of vitamins and minerals leads to deficiencies which affects body cells. “Vitamins are organic compounds that are needed in small amounts for growth, reproduction, and overall good health, and a deficiency of any one will cause physiological symptoms” (Blake 2017, p. 228). In comparison of her nutrients report to that of table 7.3, which shows deficiencies in vitamins A, D, C, & E, she is at risk of “night blindness”, “osteomalacia i.e. bone’s inability to mineralize properly due to lack of enough calcium and phosphorus” which leads to soft bones, deficiencies can also cause “nerve problems” which can lead to inability to control body parts movements, and “lower immune function” (Blake 2017, p. 264). Vitamin D is important for bone health by ‘helping with calcium and...

...Color blindness or color vision deficiency is the inability or decreased ability to see color, or perceive color differences, under lighting conditions when color vision is not normally impaired. "Color blind" is a term of art; there is no actual blindness but there is a fault in the development of one or more sets of retinal cones that perceive color in light and transmit that information to the optic nerve Muscular dystrophy (MD) is a group of muscle diseasesthat weaken the musculoskeletal system and hamper locomotion.[1][2] Muscular dystrophies are characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells andtissue.[3] Blood disorders can lead to poor blood clotting and continuous bleeding. The disorders can result from defects in the blood vessels or from abnormalities in the blood itself, such as in blood clotting factors or in platelets. Ichthyosis (plural ichthyoses) is a heterogeneous family of at least 28,[1] generalized, mostly genetic skindisorders. All types of ichthyosis have dry, thickened, scaly or flaky skin.[1] In many types there is cracked skin,[2] which is said to resemble the scales on a fish; the word ichthyosis comes from the Ancient Greek ιχθύς (ichthys), meaning "fish.

Antoine Lavoisier

...Daniel Rutherford Jacobus Henricus Walther Hermann Nernst Reinhold Benesch & Ruth Erica Benesch Find How Oxygen is Transported in Human Body Frederick Soddy Artturi Ilmari Virtanen Louis Jacques Thenard discovers hydrogen peroxide Jbir ibn Hayyn Ya'qub Al-Kindi Paul Karrer Antoine-Laurent de Lavoisier Few things are as important as water, which we know is made of oxygen and hydrogen. Did you know that Antoine Lavoisier was the discoverer of both elements? Contributions to Science Antoine-Laurent de Lavoisier is one of the most important scientists in the history of chemistry. He discovered elements, formulated a basic law of chemistry and helped create the metric system. During his time, people believed that when an object burns, a mysterious substance called ‘phlogiston’ was released. This was called the ‘phlogiston theory’. Lavoisier’s experiments demonstrated the contrary, i.e. when something burned, it actually absorbed something from the air, instead of releasing anything. He later named the ‘something’ from the air as oxygen, when he found that it combined with other chemicals to form acid. (In Greek, ‘oxy’ means sharp, referring to the sharp taste of acids.) Henry Cavendish had earlier isolated hydrogen, but he called it inflammable air. Lavoisier showed that this inflammable air burned to form a colourless liquid, which turned out to be water. The Greek word for water is ‘hydro’, so the air that burned to form water was hydrogen! Lavoisier was...

Obesity and the Effects of Fast Food in America

...Serita McKoy HON 410 Professor Yesudas Choondassery February 22, 2013 Our Future: What Fast Food is Taking From Us We as Americans are facing quite an epidemic when it comes to health. It is not as though the nation was stricken with some sort of plague or fell victim to some conspiracy. Unfortunately, the cause of our issues is much more in our control than I think we would care to admit. Our health is depleting at large numbers all because of our diet. The rates of heart related issues, blood pressure and diabetes are at astounding numbers. These medical concerns are costing the country billions of dollars in healthcare. Why and when did our health begin to plummet? Over past decades America’s love for junk and fast food is the culprit behind this country having one of the unhealthiest populations any continent has to offer. This fascination of fast food had to start somewhere. Not only that but so did awareness that this particular industry may single handedly be responsible for obesity in this country. There are few topics actually that will help to understand this phenomenon a little further beyond the awareness of fast food. There was legislation that was passed that was supposed to help Americans understand what they are consuming on a daily basis. We learn this is only as helpful as one is able to translate the information. Many people are lost when it comes to nutritional food labels and what the numbers mean when it comes to their personal diet and...
