By the way, doctor: Can even one fatty meal cause heart problems?

Q. I'm in good health and have a good lipid profile but occasionally have a yearning for brisket or corned beef. I recently read that even one meal heavy in fat could cause atherosclerosis. What do you think?

A. Unhealthy foods are not like poison. Arsenic is poisonous, and just one swallow could kill you, but it's not that way with the unhealthy saturated fats in brisket.
