In the News: Late Night Snacking May Damage Skin, Study Says You Can’t be Fit and Fat, Blood Test May Find Cancer Early

Late night snacking may damage skin. According to a recent study, eating late at night may make your skin more prone to sun damage. When studying mice, scientists discovered that if their eating patterns shifted, they became more vulnerable to UV rays. When looking for an explanation, Dr. Joseph S. Takahashi found that altering the circadian rhythm changes the way a specific skin-protecting enzyme operates. This enzyme, known as xeroderma pigmentosum group A (XPA), became less active during the day when the mice ate at different times and more active at night. While it’s not clear if this phenomenon would also impact humans, it does raise questions about how diet can impact your skin health. Want to stop nighttime eating? Try this plan. (MNT)

A study says you can’t be fit and fat. A study printed in the European Heart Journal has found that being overweight raises the risk of coronary heart disease, even if the person seems healthy overall. These findings challenge the notion that one can be overweight yet simultaneously fit. After analyzing thousands of heart disease cases in 10 European countries for over a decade, researchers discovered that being overweight was linked to a 25% higher likelihood of developing heart disease. These results will likely open a new discussion about what it really means to be healthy and whether blood tests or other assessments will be needed to determine that.

A blood test may find cancer early. A team at Johns Hopkins University has found that a blood test can detect breast, colon, lung, and ovarian cancer. While it will take a long time before this exam can be used as a method of cancer screening, it does show great promise. Scientists found that dying tumor cells shed tiny bits of DNA that can show up in the bloodstream. Interestingly, the team was able to find a lot of early-stage cancer patients having these changes in their blood. This type of testing can potentially find cancer before any symptoms even emerge. If these tests continue to be accurate over the next few years of research, it can create a huge impact in the world of early cancer detection. (NBC)
