Association of low 25-hydroxyvitamin D concentrations with elevated parathyroid hormone concentrations and low cortical bone density in early pubertal and prepubertal Finnish girls. Cheng S, Tylavsky F, Kröger H, Kärkkäinen M, Lyytikäinen A, Koistinen A, Mahonen A, Alen M, Halleen J, Väänänen K, Lamberg-Allardt C. Am J Clin Nutr. 2003 Sep;78(3):485-92. Erratum in: Am J Clin Nutr. 2006 Jan;83(1):174. PMID: 12936933 CONCLUSIONS: Vitamin D-deficient girls have low cortical BMD and high iPTH concentrations, which are consistent with secondary hyperparathyroidism. A low vitamin D concentration accompanied by high bone resorption (TRAP 5b) may limit the accretion of bone mass in young girls.

Achieving the for the most part amazing lean and muscular physique is not simple, except you are one of those gifted persons who can obtain lean muscle mass while eating a superior calories diet, and not gain any fat. It takes a regular dedication to your gym work, your diet and nutrition Program and your overall lifestyle.

There are many great reasons why protein shakes, as part of a balanced and healthy diet, can be very beneficial to the body, especially when it comes to gaining muscle mass. It's all about drinking the right type of shake at the right time. However there's a lot of unhelpful advice floating around the Internet these days.

Phosphatidylserine (PS) is a phospholipid that is found in all cells, but is most highly concentrated in the walls (membranes) of brain cells, making up about 70% of its nerve tissue mass. There it aids in the storage, release and activity of many vital neurotransmitters and their receptors. Phosphatidylserine also aids in cell-to-cell communication.

ScienceDaily (Feb. 12, 2009) - A Texas AgriLife Research scientist and fellow researchers have discovered that arginine, an amino acid, reduces fat mass in diet-induced obese rats and could help fight human obesity.

This database provides both national and sub-national adult underweight, overweight and obesity prevalence rates by country, year of survey and gender. The information is presented interactively as maps, tables, graphs and downloadable documents. These ca

A seasonal variation of calcitropic hormones, bone turnover and bone mineral density in early and mid-puberty girls - a cross-sectional study. Viljakainen HT, Palssa A, Kärkkäinen M, Jakobsen J, Cashman KD, Mølgaard C, Lamberg-Allardt C. Br J Nutr. 2006 Jul;96(1):124-30. PMID: 16870000 Seasonal variation in S-25-OHD and bone remodelling markers accompanied by negative correlation between S-25-OHD and S-iPTH was seen in this cross-sectional study of adolescent girls. In addition, the seasonal rhythm contributed 7.0-7.6 % difference in the BMD of lumbar vertebrae and left femur in early puberty girls. This variation should be avoided since it could hamper peak bone mass attainment.

ScienceDaily (Apr. 10, 2009) - New research from Trinity College Dublin published in this month's Annals of Surgery points to a potentially significant advance in the treatment of patients undergoing major cancer surgery. The study was carried out by the oesophageal research group at Trinity College Dublin and St James's Hospital. A randomised controlled trial showed omega-3 fatty acids given as part of an oral nutritional supplement resulted in the preservation of muscle mass in patients undergoing surgery for oesopahageal cancer, a procedure normally associated with significant weight loss and quality of life issues.

Calorie-restricted diets are thought to protect against cancer and slow tumor growth, and a new study published in this week's Nature begins to tease out why the measure works for some tumors, and not for others. For almost a century, researchers have known that fasting helps animals live longer and avoid some cancers, "but which type of cancers would be amenable to this approach, from a therapeutic standpoint, is still an open question," said Pier Paolo Pandolfi, a cancer geneticist at Harvard Medical School and Beth Israel Deaconess Cancer Center in Boston, Mass., who was not involved in the study. The study is exciting because it is one of the first to start answering that question at the genetic level, he said.

Vitamin D deficiency is the cause of common obesity. Foss YJ. Med Hypotheses. 2009 Mar;72(3):314-21. Epub 2008 Dec 2. PMID: 19054627 doi:10.1016/j.mehy.2008.10.005 Common obesity and the metabolic syndrome may therefore result from an anomalous adaptive winter response. The stimulus for the winter response is proposed to be a fall in vitamin D. The synthesis of vitamin D is dependent upon the absorption of radiation in the ultraviolet-B range of sunlight. At ground level at mid-latitudes, UV-B radiation falls in the autumn and becomes negligible in winter. It has previously been proposed that vitamin D evolved in primitive organisms as a UV-B sensitive photoreceptor with the function of signaling changes in sunlight intensity. It is here proposed that a fall in vitamin D in the form of circulating calcidiol is the stimulus for the winter response, which consists of an accumulation of fat mass (obesity) and the induction of a winter metabolism (the metabolic syndrome). Vitamin D deficiency can account for the secular trends in the prevalence of obesity and for individual differences in its onset and severity. It may be possible to reverse the increasing prevalence of obesity by improving vitamin D status.

"ScienceDaily (Oct. 8, 2009) - Women with breast cancer should be given high doses of vitamin D because a majority of them are likely to have low levels of vitamin D, which could contribute to decreased bone mass and greater risk of fractures, according to scientists at the University of Rochester Medical Center." Scientists funded by the NCI analyzed vitamin D levels in each woman, and the average level was 27 nanograms per milliliter; more than two-thirds of the women had vitamin deficiency. Weekly supplementation with high doses of vitamin D -- 50,000 international units or more -- improved the levels, according to Peppone's study. The U.S. Institute of Medicine suggests that blood levels nearing 32 nanograms per milliliter are adequate.

A nutrition blog by Dr. Ayers Inflammation is the foundation for cancer and degenerative/autoimmune diseases. Small changes in diet and exercise, e.g. omega-3 oils, vitamin D, low starch, plant antioxidants, and maintaining muscle mass, can dramatically alter predisposition to disease and aging, and minimize the negative impact of genetic risks. Based on my experience in biological research, I am trying to explain how the anti-inflammatory diet and lifestyle combat disease. Anti-Inflammatory Diet All health care starts with diet. Here are my recommendations for a basic Anti-Inflammatory Diet and Lifestyle. There are over 140 articles on diet, inflammation and disease here, and more articles by Dr. Ayers on Suite101 .

"DALLAS, Jan. 8 - The same vitamin D deficiency that can result in weak bones now has been associated with an increased risk of cardiovascular disease, Framingham Heart Study researchers report in Circulation: Journal of the American Heart Association. "Vitamin D deficiency is associated with increased cardiovascular risk, above and beyond established cardiovascular risk factors," said Thomas J. Wang, M.D., assistant professor of medicine at Harvard Medical School in Boston, Mass. "The higher risk associated with vitamin D deficiency was particularly evident among individuals with high blood pressure." In a study of 1,739 offspring from Framingham Heart Study participants (average age 59, all Caucasian), researchers found that those with blood levels of vitamin D below15 nanograms per milliliter (ng/mL) had twice the risk of a cardiovascular event such as a heart attack, heart failure or stroke in the next five years compared to those with higher levels of vitamin D."

Conjugated linoleic acid supplementation for 1 y does not prevent weight or body fat regain. Larsen TM, Toubro S, Gudmundsen O, Astrup A. Am J Clin Nutr. 2006 Mar;83(3):606-12. PMID: 16522907 CONCLUSION: A 3.4-g daily CLA supplementation for 1 y does not prevent weight or fat mass regain in a healthy obese population.

"A recent thesis presented at the University of Gothenburg, Sweden, shows that eight-year-old children who drink full-fat milk every day have a lower Body Mass Index (BMI) than those who seldom drink milk. The study showed that children who drink full-fat milk every day weigh on average just over 9 lbs less"

Not only does protein increase your metabolism so you can burn more calories all day long, but protein is also going to be necessary to preserve your lean muscle mass over the long haul. Easy tricks to get more protein in your diet.

In later stage of aids, pernicious form of weight loss seen, called wasting. Serostim, a form of recombinant HGH is used to reverse this effect. Wasting is the accidental loss of weight in which the lean muscle, the body mass, the bones, and the body organs are all shrinking away.
