Eating fish helps lower high blood pressure.
Eating fish and its constituent omega-3 fatty acids and proteins is supported by animal and review evidence as beneficial for lowering high blood pressure and supporting cardiovascular health.
The claim that eating fish helps lower high blood pressure is supported by studies demonstrating that fish consumption and fish protein intake attenuate blood pressure increases in animal models and contribute to cardiovascular health in nutritional reviews. No papers refute the claim directly, leading to a supported verdict.
