Omega-3 in fish: How eating fish helps your heart

The omega-3 fatty acids in fish are good for your heart. Find out why the heart-healthy benefits of eating fish usually outweigh any risks.

If you’re worried about heart disease, eating one to two servings of fish a week could reduce your risk of dying of a heart attack.

For many years, the American Heart Association has recommended that people eat fish rich in omega-3 fatty acids at least twice a week. Doctors have long believed that the unsaturated fats in fish, called omega-3 fatty acids, are the nutrients that reduce the risk of dying of heart disease. However, more-recent research suggests that other nutrients in fish or a combination of omega-3 fatty acids and other nutrients in fish may actually be responsible for the health benefits from fish.

Could tai chi encourage more patients to take up cardiac rehab?


Preliminary research suggests that tai chi, with its slow, gentle approach, might offer a safe and attractive option for patients who do not take up conventional cardiac rehabilitation.

A report on the study, which has been published in the Journal of the American Heart Association, explains that the majority of heart attack patients who are offered cardiac rehab refuse it, in many cases because they are put off by physical exercise.

Some patients are put off cardiac rehab because they believe that it might be painful, unpleasant, or perhaps not even achievable in their current physical condition.

If inflammation triggers coronary disease, might targeting it directly — beyond simply reducing cholesterol — decrease the risk of heart attacks? Over the course of a decade, Libby and Ridker found themselves focusing on a molecule involved in inflammation called interleukin-1 beta. By the mid-2000s, they heard of a new drug — an interleukin-1-beta inhibitor — that was used to treat exceedingly rare inflammatory diseases. In April 2011, Ridker’s team started enrolling 10,000 patients who carried signs of inflammation and were at very high risk for coronary disease in a randomized study to determine the effects of the inhibitor on heart disease and strokes.
