Plasma 25-hydroxyvitamin d is associated with markers of the insulin resistant phenotype in nondiabetic adults. Liu E, Meigs JB, Pittas AG, McKeown NM, Economos CD, Booth SL, Jacques PF. J Nutr. 2009 Feb;139(2):329-34. Epub 2008 Dec 23. PMID: 19106328 doi:10.3945/jn.108.093831 After adjusting for age and sex, plasma 25(OH)D was positively associated with ISI(0,120), plasma adiponectin, and HDL cholesterol and inversely associated with plasma triacylglycerol, but these associations were no longer significant after further adjustment for BMI, waist circumference, and current smoking status. 25(OH)D and 2-h post-OGTT glucose were not associated. Among adults without diabetes, vitamin D status was inversely associated with surrogate fasting measures of insulin resistance. These results suggest that vitamin D status may be an important determinant for type 2 diabetes mellitus.

"Summer vs Winter Mode: Explaining AMPK Last year I read an article which made a statement that has not left my mind. The statement went as follows: "You are only good as your mitochondria." In fact, the more a dwell into the details of human metabolism, the more I sense that this is true - especially with the metabolic syndrome. For those who are not familiar with the concept of mitochondria, they are the tiny energy factories within the cells that produce cellular energy through aerobic means (meaning oxygen). Mitochondria utilize oxygen to ultimately produce Adenosine Triphosphate or simply ATP. ATP relays energy by donating a phosphate bond resulting in Adenosine Diphosphate (ADP). Another phosphate release would entail Adenosine Monophosphate or AMP. ATP is one of the main sources of cellular energy in the body

"Had enough about reading/hearing about Vitamin D? Well, it keeps on coming. And for my lack of surprise, the medical community in general is not catching on like wild fire. I really don't understand it. A recent study from the Heart Institute at Intermountain Medical Center in Salt Lake City (click) followed 27,686 patients greater than 50 years of age with no prior history of cardiovascular disease. The Vitamin D levels were checked and classified as such: * normal - greater than 30 ng/ml * low - 15 to 30 * very low - less than 15 The results of the study showed that patients with very low Vitamin D levels in comparison to normal had: * 77% greater risk of death * 45% increased risk of coronary artery disease * 78% increased risk of stroke * twice the risk of developing heart failure"
