For decades, we have heard the suggestion that a glass of wine each night is good for our heart, and our health. Recently, studies have called into question that assumption, showing that it was based on flawed research studies. A new study published in the Journal of Clinical Nutrition shows that having even one alcoholic drink a day can negatively impact your health. English researchers found that while wine drinkers do have a decreased risk of coronary artery disease, they have a higher overall risk of cardiovascular events like heart attacks, strokes and heart failure.
