Multivitamin use linked to less healthy behaviors

The lack of evidence on multivitamin health benefits is no impediment to their widespread popularity, with over half the U.S. population popping such pills. This translates into a $27 billion industry, which lures consumers with the illusory promise of better health. But shocking new research suggests taking multivitamins might have the opposite effect -- not simply on the metabolic level, but on a metaphysical one: promoting a false sense of invulnerability that actually leads users to engage in riskier behaviors.

More risk of health problems in lean children who become obese as adults

Insulin sensitivity in the ovaries and the pituitary linked to infertility

Infertility is common among obese women, but the reasons remain poorly understood and few treatments exist. Now a team of Johns Hopkins Children's Center scientists, conducting experiments in mice, has uncovered what they consider surprising evidence that insulin resistance, long considered a prime suspect, has little to do with infertility in women with type-2 diabetes, polycystic ovary syndrome and metabolic syndrome, all obesity-related conditions.

Evacetrapib drug may increase HDL-C and decrease LDL-C levels

Among patients with sub-optimal low-density lipoprotein cholesterol (LDL-C) or high-density lipoprotein cholesterol (HDL-C) levels, use of the drug evacetrapib alone or in combination with statin medications was associated with significant increases in HDL-C levels and decreases in LDL-C levels, according to a study appearing in the November 16 issue of JAMA, a theme issue on cardiovascular disease.

Scientists discover definitive role for brain in regulating loss of muscle mass

Patients with cancer, heart disease and other chronic illness struggle not only with complications inherent to their disease, they also experience an involuntary loss of weight and muscle mass triggered by the body's natural response to infection and inflammation. Increasing nutrition intake does not mitigate the process and there is no treatment.

Children advised to get tested for cholesterol: Guidelines

According to latest medical guidelines announced Friday, all children aged 9 to 11 should have their cholesterol checked to help head off cardiovascular disease early. Overweight children and those who have other risks of Type 2 diabetes should be screened for diabetes every two years starting as early as 9, according to the panel.

New clues about connections among fat, inflammation and insulin resistance

In a new study, scientists report that they substantially curbed weight gain, improved metabolism, and improved the efficacy of insulin in mice by engineering them to express a specific human enzyme in their fat tissue. Although the obesity prevention came at the significant cost of widespread inflammation, the research offers new clues about the connections among obesity, insulin resistance and type 2 diabetes, and inflammation.

Lower glycemic index diet may delay onset of AMD-like lesions

Feeding older mice a lower glycemic index (GI) diet consisting of slowly-digested carbohydrates delays the onset of age-related, sight-threatening retinal lesions, according to a new study from the Laboratory for Nutrition and Vision Research at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University.
