Coronary artery disease pathogenesis and treatment urgently requires a paradigm shift. Despite poplar belief among doctors and the public, the conceptual model of dietary saturated fat clogging a pipe is just plain wrong. A landmark systematic review and meta-analysis of observational studies showed no association between saturated fat consumption and (1) all-cause mortality, (2) coronary heart disease (CHS), (3) CHD mortality, (4) ischemic stroke or (5) type 2 diabetes in healthy adults. Similarly in the secondary prevention of CHD there is no benefit from reduced fat, including saturated fat, on myocardial infarction, cardiovascular or all-cause mortality. It is
instructive to note that in an angiographic study of postmenopausal women with CHD, greater intake of saturated fat was associated with less progression of atherosclerosis whereas carbohydrate and polyunsaturated fat intake were associated with greater progression. (source)
Excess Light Exposure May Take Toll on Muscles and Bones

Every day people are exposed to hours of artificial light from a variety of sources - computers, video games, office lights and, for some, 24-hour lighting in hospitals and nursing homes.
Now new research in animals shows that excessive exposure to “light pollution” may be worse for your health than previously known, taking a toll on muscles and bone strength.
Researchers at Leiden University Medical Center in the Netherlands tracked the health of rats exposed to six months of continuous light compared to a control group of rats living under normal light-dark conditions - 12 hours of light, followed by 12 hours of dark.
During the study, the rats exposed to continuous light had less muscle strength and developed signs of early-stage osteoporosis. They also got fatter and higher blood glucose levels. Several markers of immune system health also worsened, according to the report published in the medical journal Current Biology. (source)
