Eating Fish May Protect Your Kidneys

According to a study published in this month's issue of the American Journal of Kidney Diseases eating fish at least twice a week may lower the chances of developing kidney disease for adults with diabetes.

For the study, researchers from Addenbrooke's Hospital in Cambridge Massachusetts studied the diets of 22,384 men and women using a food frequency questionnaire. Of the cases reviewed, 517 patients had diabetes, mostly type 2.

To evaluate kidney disease risk, researchers measured the level of a protein called albumin in the urine of the participants. Albumin is normally filtered by our kidneys but when they aren't working properly small amounts of the protein can leak into urine.

The researchers found that participants who consumed at least two servings of fish a week were less likely to have the protein in their urine, and therefore less likely to have kidney disease.

Specifically, the researchers identified that patients with diabetes who did not eat fish on a regular basis had an 18 percent rate of kidney disease compared to only 4 percent of the patients who ate at least two servings a week.

According to lead investigator Chee-Tin Christine Lee, these results may be due to a change in blood lipid profiles which can lead to decreased risk of kidney disease and other health problems. A blood lipid profile measures the amount of certain fats in your blood such as cholesterol and triglycerides.

Although this study did not determine what kinds of fish may be best for lowering the risk of developing kidney disease, the researchers are confident that future studies will be able to find an answer to this question.

Even if you are not suffering from diabetes, increasing your consumption of fish is a good way to get more essential omega-3's and other beneficial nutrients in your diet. Omega-3s have been associated with a number of health benefits like lower cholesterol and blood pressure, reduced dementia risk and higher cognitive function, just to name a few.

An easy way to get more omega-3s it to use a high quality fish oil supplement. Look for one that's certified for purity and potency so you can be sure it doesn't contain dangerous contaminants. Also be sure that the product will deliver at least 650mg of the most important omega-3s, EPA and DHA.
