DEAR DOCTOR K: Heart disease runs in my family. Should I eat fish, or take fish oil supplements?
DEAR READER: Eating fish regularly reduces a person's risk of sudden death from heart disease. It's also brain-healthy. For that reason, I and most doctors recommend a regular diet of fish for people who have heart disease. And also for people like you where heart disease runs in the family. Fish oils are rich in omega-3 fatty acids, a kind of "healthy fat."
