Report: Is saturated fat really bad for your heart? Last week, a report in the Annals of Internal Medicine questioned the idea of saturated fats being a significant factor in cardiovascular disease. It stated, "Current evidence does not clearly support cardiovascular guidelines that encourage high consumption of polyunsaturated fatty acids and low consumption of total saturated fats." Not so fast, said Dr. David Katz, a renowned physician and inventor of the NuVal score. He said the study, which is pooled from previously published studies, does not refute what we know about nutrition. He said the meta-analysis does not consider other factors that contribute to heart disease. See the report here: tinyurl.com/mnxu6ml. See Dr. Katz's response here: tinyurl.com/kboubk8.
