Combining daily consumption of fish providing ~3.65g of n-3 fatty acids with a weight-reducing diet produces additive reductions in 24-hour ambulatory blood pressure and heart rate in overweight, medication-treated hypertensives compared to either intervention alone.
If you are overweight and have high blood pressure, adding daily fish meals (providing about 3.65g of omega-3s) and losing weight can significantly lower your blood pressure and heart rate. The combination works better than either alone. You should continue your blood pressure medication unless your doctor advises otherwise, but these dietary changes may help reduce your overall cardiovascular risk.
Dietary fish and weight loss had significant independent and additive effects on 24-hour ambulatory BP... Combining a daily fish meal with a weight-reducing regimen led to additive effects on ambulatory BP and decreased heart rate.
Why this rating
