IgA Nephropathy Patient should be a Vegetarian

2014-04-01 16:53

Diet may play a very important role in the recovery or the treatment for the IgA Nephropathy patients. Proper diet may slow down development process of kidney disease. What should the IgA Nephropathy patients eat? Should patients with IgAN be Vegetarian? Let’s find the answers below together.

1. Low protein & salt is wise

Nephropathy, kidney disease, regardless of cause, generally dictates a diet lower in protein and in sodium (table salt). If renal function is perfectly normal and you only have moderate protein losses in urine, you may not need to restrict your protein intake. But patients with IgAN must follow a proper diet. The degree of restriction depends on the degree of current kidney compromise, the expectation of future damage, & the presence of other contributory risk factors like diabetes or hypertension. Fish oil is useful for IgA nephropathy, but you will be getting this in capsules. If you still have some questions, please chat with our online doctor.

2. Be a vegetarian

Patients with IgAN should drastically reduce their consumption of meat; even adopted wholly vegetarian diets. A vegetarian diet saves the kidneys a lot of hard work in clearing the byproducts of protein metabolism. By reducing strain on the kidneys, we hope to preserve function longer.

Fatty acids are mediators of inflammation becuase of their ability to form compounds known as prostaglandins. There are good and bad prostaglandins; the good kind have anti-inflammatory effects, the bad kind fuel the fires.

A "bad" fatty acid is arachidonic acid, which is derived almost entirely from meat and dairy products. Animal foods also tend to be high in saturated fats, which can also increase the inflammatory response. One of the products of arachidonic acid metabolism is thromboxane, which plays a role in glomerulosclerosis, or the scarring of the glomeruli.

A "good" fatty acid is eicosapentaenoic acid (EPA), the active ingredient in the fish oil that is widely being used now to treat IgAN and which helps form anti-inflammatory prostaglandins.

In sum, a vegetarian diet may a doubly protective effect in IgAN, first, by reducing the strain on the kidneys of metabolizing animal proteins, and second, by reducing the inflammatory response that damages the kidneys.
