Tuna - not recommended for heart disease?

Why is tuna not recommended for people with heart disease?

I would question the source of your information because tuna is recommended for people with heart disease. It has been known for some time that people who eat lots of fish in their diet have a lower incidence of heart disease. The Inuit people, in particular, eat a diet that is rich in blubber but yet their level of heart disease is low. The reason for this paradox is that the fat in their diet largely consists of polyunsaturated fatty acids. Polyunsaturated fats are also known as omega-3 fatty acids. Oily fish, such as mackerel, salmon, sardines and tuna are rich in polyunsaturated fats. It is generally recommended that polyunsaturated fats should replace saturated fats in the diet in order to reduce the incidence of heart disease. A recent report in the New England Journal of Medicine, called the Physician’s Health Study, stated that polyunsaturated fatty acids were “strongly associated with a reduced risk of sudden death among men without evidence of prior cardiovascular disease”.
