This week in health science |
Are eggs really bad for your heart? Do popular weight loss drugs affect your vision? Can a simple supplement improve heart function? This week's research roundup challenges what we thought we knew about these vital health questions.
Remember being told to limit egg consumption? That advice, dating back to 1968, has been quietly reversed. Recent research shows eggs have little impact on overall cholesterol levels and are actually valuable sources of nutrients. Meanwhile, other cholesterol findings have surprised scientists: high levels of “good” HDL cholesterol might increase glaucoma risk in people over 55.
The story of GLP-1 medications like Ozempic continues to develop. A new review has identified nine cases of severe vision problems, including potentially blinding conditions. These medications were prescribed for 2% to 3% of Americans in 2023. Dr. Bradley Katz emphasized that “it’s critical to monitor any ill effects on the eye or other parts of the body.”
In more promising news, research suggests ketone supplements might improve heart function, particularly in older adults with type 2 diabetes. However, with only 13 participants in the study, scientists caution that more research is needed before making broad recommendations.
