It is no secret that diet can make an impact on your health - especially when it comes to the health of your heart. In the latest revision of its dietary guidelines, the AHA is recommending two servings of fish a week, preferably fatty fish such as salmon or tuna, which are high on omega-3 fatty acids. This new addition is based on a number of studies suggesting that fish can make a difference when it comes to protecting the heart. Researchers believe that when combined with a healthful eating plan, the omega-3 fatty acids can actually lower the risk of heart attack and sudden cardiac arrest due to an irregular heartbeat. In fact, researchers have found that, among those who consume higher quantities of fish oil, a lower level of saturated fat was consumed.
Fish oil appears to have an additional benefit as well.
It has been found to lower a person's blood pressure if it is high. However, the reduction is minimal and it may not be long lasting. There is a negative, too, if a person goes overboard on their consumption of fish. Fish oils can interfere with the clotting of blood, which can ultimately be harmful if large amounts of the oil are consumed. These fatty acids are also found in shellfish and crustaceans such as shrimp and oysters.
