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. 

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.
