Health Benefits of Cod and Tilapia

Seafood like cod and tilapia are heart healthy 4. Due to their omega-3 fatty acids, B vitamins and minerals like potassium and magnesium, they benefit cholesterol, blood pressure and help lower the risk of heart disease 5.

Omega-3 Fatty Acids

Why are omega-3 fatty acids so beneficial? Omega-3 fatty acids are heart healthy and help keep bad cholesterol low, increase good cholesterol and keep arteries healthy. Two of the fatty acids, DHA and EPA are associated with lowering blood pressure and improving the health of blood vessels 6.

Potassium

Potassium is beneficial for combating high sodium intake because it helps the body reduce fluids and rids excess sodium 7. This process helps to reduce blood pressure.

Magnesium

Magnesium is also beneficial for the heart and helps to lower blood pressure. It achieves this by helping the blood vessels to relax and controls other nutrients like potassium and calcium 8.

Calcium

Calcium, like potassium is important for blood pressure and the heart. Harvard Health reports calcium helps maintain blood pressure because it helps to control the relaxing and tightening of blood vessels.

In addition it’s helpful with the release of enzymes and hormones needed for most body functions. A recent study of adult women showed calcium supplementation can lower diastolic blood pressure significantly 9.

Seafood is renowned for being a part of many diets like keto or heart healthy.
