7. Fish: Omega-3 Fatty Acids for Heart Health
Fish is a rich source of protein and can be a great option for those with kidney failure. It is important for those with kidney disease to pay attention to their protein intake, as the kidneys play a crucial role in filtering waste and excess protein from the bloodstream.
In kidney failure, the kidneys are unable to effectively remove waste and excess fluids from the body, leading to a buildup of toxins in the bloodstream. As a result, individuals with kidney failure may need to limit their protein intake to prevent further damage to their kidneys.
However, fish is a valuable protein source for those with kidney failure, as it is low in phosphorus and potassium, two minerals that can be harmful for individuals with kidney disease in excess. In addition, fish is a good source of omega-3 fatty acids, which have been shown to support heart health. Omega-3 fatty acids have been shown to lower blood pressure, reduce inflammation, and decrease the risk of heart disease.
Fish is also low in saturated fat, which is important for those with kidney disease, as high levels of saturated fat can increase cholesterol levels and contribute to heart disease. Instead, fish is high in unsaturated fats, which are beneficial for heart health and can help reduce inflammation in the body.
There are many different types of fish that are high in omega-3 fatty acids, including salmon, sardines, and anchovies. These types of fish are also low in mercury, which is a concern for individuals with kidney disease, as high levels of mercury can be harmful to the kidneys. Additionally, some individuals with kidney disease may need to limit their intake of fish, as it can also contain purines, which can contribute to the formation of kidney stones.
Choose fish varieties like salmon, mackerel, and trout for the highest omega-3 content. Aim to consume fish at least twice a week as part of your kidney failure diet plan, but be mindful of portion sizes to avoid excessive phosphorus intake. (7)
