High blood pressure can be improved by eating Canned sardine.
Canned sardine is rich in EPA. Canned sardine contains about two times as much as canned mackerel.
Why EPA improves High Blood Pressure?
When we eat meals, salt comes into the blood vessel. To reduce the density of salt, a lot of water also comes into the blood vessel. The increase of water pressurizes the wall of the blood vessel. This condition is high blood pressure. When EPA comes into the blood vessel, EPA softens the wall of the blood vessel and lowers the pressure.
Canned sardine in brine is recommended because raw sardine is canned, so EPA is not lost, compared to seasoned canned sardine.
The benefit of eating canned sardine in brine is that you can lower your blood pressure without changing your usual diet.
Tomato helps more improvement of high blood pressure when eaten with canned sardine in brine.
Since EPA is easily oxidized, the amount of EPA reduces because of being oxidized by active oxygen. But lycopene contained in tomato removes active oxygen and protects EPA from oxidization.
