The Skeletal System


Nutrition's Impact on the Skeletal System
Vitamin K plays a role similar to vitamin D in bone health. This calcium is lost through your urinary system. The last step of bone remodeling continues for months, and for a much longer time afterward the mineralized bone is continuously packed in a more dense fashion. Bone outperforms reinforced concrete by several orders of magnitude in compression and tension strength tests. For example, phosphorus supports your skeletal system, but eating more does not necessarily make your bones stronger. You can obtain calcium from foods other than milk to support bone health.

How to Keep Your Skeletal System Healthy

In adulthood, our bones stop growing and modeling, but continue to go through a process of bone remodeling. In the process of remodeling, bone tissue is degraded and built up at the same location. About 10 percent of bone tissue is remodeled each year in adults. Bones adapt their structure to the forces acting upon them, even in adulthood. This is why exercising, especially when it involves weight-bearing activities, increases bone strength.

The first step in bone remodeling is osteocyte activation. Osteocytes detect changes in mechanical forces, calcium homeostasis, or hormone levels. In the second step, osteoclasts are recruited to the site of the degradation. Osteoclasts are large cells with a highly irregular ruffled membrane. These cells fuse tightly to the bone and secrete hydrogen ions, which acidify the local environment and dissolve the minerals in the bone tissue matrix.

This process is called bone resorption and resembles pit excavation. Our bodies excavate pits in our bone tissue because bones act as storehouses for calcium and other minerals. Bones supply these minerals to other body tissues as the demand arises. Bone tissue also remodels when it breaks so that it can repair itself.

Moreover, if you decide to train to run a marathon your bones will restructure themselves by remodeling to be better able to sustain the forces of their new function. After a certain amount of bone is excavated, the osteoclasts begin to die and bone resorption stops. In the third step of bone remodeling, the site is prepared for building. These first three steps take approximately two to three weeks to complete. In the last step of bone remodeling, osteoblasts lay down new osteoid tissue that fills up the cavities that were excavated during the resorption process.

Osteoid is bone matrix tissue that is composed of proteins such as collagen and is not mineralized yet. To make collagen, vitamin C is required. A symptom of vitamin C deficiency known as scurvy is bone pain, which is caused by diminished bone remodeling.

After the osteoid tissue is built up, the bone tissue begins to mineralize. The last step of bone remodeling continues for months, and for a much longer time afterward the mineralized bone is continuously packed in a more dense fashion. Thus, we can say that bone is a living tissue that continually adapts itself to mechanical stress through the process of remodeling. For bone tissue to remodel certain nutrients such as calcium, phosphorus, magnesium, fluoride, vitamin D, and vitamin K are required.

Bone mineral density BMD is a measurement of the amount of calcified tissue in grams per centimeter squared of bone tissue. BMD can be thought of as the total amount of bone mass in a defined area. When BMD is high, bone strength will be great. Similar to measuring blood pressure to predict the risk of stroke, a BMD measurement can help predict the risk of bone fracture.

Testosterone High essential minerals for a healthy skeletal system. A diet high in essential minerals will strengthen your skeleton. As we have learned in class, the two most important minerals for your skeletal system are phosphorus and calcium, but you may be wondering why is this? And where do these minerals come from. Calcium Calcium is substance that is important for people to have strong and healthy bones and is really important for your bones.

Calcium helps your nerves, muscles and heart function properly and is a major component of your bone and teeth to help form their structure. Calcium rich foods such as black eye peas, kelp and oranges are foods that should be in our diets. Vitamin K helps keep your calcium levels balanced, so it is also important to eat foods high in vitamin K such as leafy greens and broccoli.

Testosterone Not only your diet impacts your skeletal system, your hormones do as well. In order to have a healthy skeletal system you want to have healthy hormonal levels as well.

Testosterone is a vital muscle building hormone that is affected best through a low fat diet and omega-3 and omega-6 fatty acids. How do different diets impact the skeletal system??? By Taylor, cara and Brianna A decrease in your testosterone levels will cause your ability to build muscle to be at risk.

More than 30 percent of women over the age of 50 will suffer from osteoporosis at some time in their lives, the International Osteoporosis Foundation states. Osteoporosis is the result of low bone mineral density, which causes weak and brittle bones.

Nutrition is one of the most important aspects of a healthy and osteoporosis-resistant skeletal system. Calcium It's widely known that consuming dairy products like yogurt and cheese is good for your skeleton. Most of the bony benefits that come from dairy's rich calcium content. As the cement that builds the foundation of your bones, calcium is also needed for other bodily functions like muscle contractions. If you don't get enough from your diet, then your body leeches the calcium stored in your bones.

In addition to dairy, good sources of calcium include green leafy vegetables, broccoli and almonds. Adults should aim for 1, mg of dietary calcium per day. Magnesium More than half of the magnesium stored inside your body is found in your skeletal system.

But the Office of Dietary Supplements adds that many people don't reach their daily magnesium target of mg for men and mg for women.
