Those with high protein intakes would have tended to be high in both meat and dairy, and those with high calcium intakes would have been high specifically in dairy. Potassium absorption was separately analyzed in those above and below the median intakes for the 2 nutrients. Potassium absorption remained above 90% on both sides of the protein and calcium medians (Table 1), and the small differences between them were not statistically significant. From the failure to find a difference at low and high meat and dairy intakes, it can be concluded that potassium is uniformly well absorbed regardless of dietary source.
A notable feature of the calcium economy is that adjustments of calcium absorption and excretion can diminish the impact of a high calcium intake or compensate for a low calcium intake. Quantifying various nutrient and whole-food effects on the calcium economy provides valuable data for public health professionals, clinicians, and nutritionists to counsel patients on achieving calcium balance; however, simply put, all true nutrient effects on the calcium economy can be managed either by reducing excess intake of the nutrient concerned or by increasing calcium intake. The most effective approach to improving calcium nutriture and preserving the calcium economy is to increase consumption of those foods naturally nutrient-rich in calcium, vitamin D, protein, phosphorus, and potassium. At present, the food source that best achieves such a naturally nutrient-rich designation is dairy.
According to Tvlasvsky, Spence & Harkness (2008), the role of dietary potassium in moderating bone mass rests in the intricate interaction between...
NUTRITION What is Nutrition? Good Nutrition Important Food Elements NUTRITION FOR A HEALTHY MIND AND BODY Benefits of Good Nutrition Nutrition for a Healthy Body Nutrition for a Healthy Mind Nutrition for the Future What is Nutrition? The most basic definition of nutrition is "the science of how food nourishes the body." (Null) Still, nutrition is a very broad and complex subject. The food we eat must go through many changes before our bodies can use it for nutrition. Nutrition
Osteoporosis is a disease which effects bone density in the human body. This increases the risk of fracture. Osteoporosis, means "porous bones," and is essentially a condition that arises when the amount of calcium necessary for bone density and structure slowly decreases and therefore makes the body more vulnerable to fractures. (Osteoporosis) This disease affects a large number of people every year. While commonly those over the age of fifty
Treatment of osteoporosis revolves around specific calcium and vitamin D medication programs but first and foremost in importance is the institution of regular, healthy and appropriately strenuous exercise. This helps to strengthen both muscle support for fragile bones and improves ambulatory abilities to the end of helping to reduce the likelihood of accidents. Additionally, a lifestyle of activity can have decidedly positive preventative properties as well, serving as one of
5 SD below Osteoporosis > 2.5 SD below Severe osteoporosis and fragility fracture > 2.5 SD below BMD = bone mineral density; SD = standard deviation Beck and Shoemaker (2000) state that "calcium consumption alone is not considered adequate protection against osteoporosis" however calcium does play "an important role in the prevention and management of postmenopausal osteoporosis. " Optimal calcium intake as stated by the National Institutes of Health are those
They are most effective in the spine, which is the most common site of osteoporotic fracture. The role of adequate calcium intake has always been mentioned as most essential in the growth and development of all normal tissues, including bone. A low-calcium diet restricts the intake of dairy products, has low amounts of fruits and vegetables, and includes a high intake of low-calcium beverages. Other dietary factors can also
Preventative measures can help keep bones strong and healthy. Calcium, phosphorous, and Vitamin D absorption are keys to preventing osteoporosis as well as treating the condition to prevent injury. Cigarette smoking and heavy drinking may exacerbate osteoporosis, and refraining from smoking and drinking can also prevent the condition from developing. Some medications have been developed specifically to increase bone density and prevent osteoporosis from worsening. Treatments for osteoporosis include exercise,
