One of the best signs of good health is how quickly the heart returns to resting rate after exercise. In this study, doctors compared levels of omega-3 fatty acids and heart recovery rate in 13,912 healthy men and women, average age 50. A 2-percentage-point increase in omega-3s—where 8 percent is the ideal level—brought heart rate down 0.35 beats per minute (BPM) in men, and 0.69 BPM in women. Overall, men and women recovered an average 24 BPM after one minute, and 53 BPM after three minutes.
Doctors said, “omega-3s make the heart light on its feet, not sluggish in its response.”
