The Good Role of “Bad” Cholesterol, & Other News of Note

“Bad” Cholesterol Not as Bad as People Think, Study Shows (ScienceDaily)

The so-called “bad cholesterol” – low-density lipoprotein commonly called LDL – may not be so bad after all, shows a Texas A&M University study that casts new light on the cholesterol debate, particularly among adults who exercise.

Steve Riechman, a researcher in the Department of Health and Kinesiology, says the study reveals that LDL is not the evil Darth Vader of health it has been made out to be in recent years and that new attitudes need to be adopted in regards to the substance. [The study] is published in the Journal of Gerontology.

Riechman and colleagues examined 52 adults from ages to 60 to 69 who were in generally good health but not physically active, and none of them were participating in a training program. The study showed that after fairly vigorous workouts, participants who had gained the most muscle mass also had the highest levels of LDL (bad) cholesterol, “a very unexpected result and one that surprised us…More

Supermarket Lights Affect Spinach Nutrients (This Week in Alternative Medicine)

Just about a year ago scientists working for the USDA’s Agricultural Research Service discovered that spinach stored on supermarket shelves held on to more of their nutrients—and even continued to make nutrients—if the leaves were exposed to light around the clock. Today the USDA, in its Agricultural Research magazine, is once again reminding customers that reaching into the back of the display case may not be the best practice—especially when it comes to leafy greens…More

“Apple a Day” Advice Rooted in Science (ScienceDaily)

According to Dr. Bahram H. Arjmandi, PhD, RD, Margaret A. Sitton Professor and Chair, Department of Nutrition, Food and Exercise Sciences at The Florida State University, apples are truly a “miracle fruit” that convey benefits beyond fiber content. Animal studies have shown that apple pectin and polyphenols in apple improve lipid metabolism and lower the production of pro-inflammatory molecules. Arjmandi’s most recent research is the first to evaluate the long-term cardioprotective effects of daily consumption of apple in postmenopausal women.

The results of this USDA-funded study [were] presented at Experimental Biology 2011 on April 12 in Washington, DC…More

Diet, Not Meds, Best for Osteoporosis (Futurity.org)

Prescription bone-building medications are expensive and have side effects, including, ironically, an increase in hip fractures and jaw necrosis. A new study suggests they should be used as a last resort if diet and supplements don’t work.

A new study, published in the journal Nutrients, finds that increasing calcium and vitamin D increases bone mineral density and reduces hip fracture risk in most adults. A majority of the results came from supplements, but food is also a good source…More

Nations Requiring the Most Vaccines Tend to Have the Worst Infant Mortality Rates (Natural News)

A new study, published in Human and Experimental Toxicology, a peer-reviewed journal indexed by the National Library of Medicine, found that nations with higher (worse) infant mortality rates tend to give their infants more vaccine doses. For example, the United States requires infants to receive 26 vaccines – the most in the world – yet more than six U.S. infants die per every 1000 live births. In contrast, Sweden and Japan administer 12 vaccines to infants, the least amount, and report less than three deaths per 1000 live births…More

Too Much or Too Little Sleep May Accelerate Cognitive Aging, Study Shows (ScienceDaily)

A study in the May 1 issue of the journal Sleep describes how changes in sleep that occur over a five-year period in late middle age affect cognitive function in later life. The findings suggest that women and men who begin sleeping more or less than 6 to 8 hours per night are subject to an accelerated cognitive decline that is equivalent to four to seven years of aging…More

The Benefits of Meditation: Neuroscientists Explain Why the Practice Helps Tune Out Distractions & Relieve Pain (MedicalXpress)

Studies have shown that meditating regularly can help relieve symptoms in people who suffer from chronic pain, but the neural mechanisms underlying the relief were unclear. Now, MIT and Harvard researchers have found a possible explanation for this phenomenon.

In a study published online April 21 in the journal Brain Research Bulletin, the researchers found that people trained to meditate over an eight-week period were better able to control a specific type of brain waves called alpha rhythms.

“These activity patterns are thought to minimize distractions, to diminish the likelihood stimuli will grab your attention,” says Christopher Moore, an MIT neuroscientist and senior author of the paper. “Our data indicate that meditation training makes you better at focusing, in part by allowing you to better regulate how things that arise will impact you.”…More
