High Blood Pressure: Nutrition Tips - Topic Overview
What does not lower blood pressure?
Fish and fish oil
Fish or fish oil supplements do not lower blood pressure. But eating fish can help lower your risk for heart disease.
You can eat fish as part of the DASH diet. Fish is part of heart-healthy eating. The American Heart Association suggests eating at least two servings of fish a week. Oily fish, which contain omega-3 fatty acids, are best for your heart. These fish include tuna, salmon, mackerel, lake trout, herring, and sardines.
Garlic and onions
Although eating garlic and onions has been recommended to
reduce blood pressure, evidence shows that only very small decreases in blood
pressure may result.
