I recently dealt with palpitations due to high blood pressure and a lower than normal potassium level. Since then, I've been able to get my potassium levels back to normal, but my blood pressure is still a little high (normally about 145/75). I hear that salmon is good for the heart due to the high levels of potassium and omega-3 fatty acids. However, when I went to the store to get some, I noticed that salmon also has high levels of cholesterol and sodium, which can't be good for the heart. So my question: is salmon really good for the heart? Do the positives outweigh the negatives?
