Sulfates in Lacto-Ovo Vegetarians

There is not much research on vegans and kidney disease, and the page on Vegetarian Diets for People with Kidney Disease is fairly bare bones; mostly links to resources for people with kidney disease who want to be vegetarian.

However, a report on lacto-ovo vegetarians that could be important for kidney disease was released in April, so I decided to add it to the page. The addition is short, so I’ve reproduced it here:

“A 2012 study on lacto-ovo vegetarians, without kidney disease, found the urine of vegetarians to have a 60% lower amount of two different sulfates that are thought to be toxic and are problematic for patients with kidney disease (1). The lower amounts were thought to be due to a combination of lower protein intake, higher fiber intake, and difference in bacteria in the digestive tract.”

    I have kidney disease and I am vegan! I was diagnosed with Poly-Cystic kidney disease (PKD) when I was 19, I was a vegetarian since age 15 for animal reasons I am now 36 and I have been vegan for 8 of those years! I tell people constantly how important it is to diseased kidneys to limit and ideally cut out all animal proteins and they are so confused by this. Animal products in your diet makes it acidic and very, very taxing on your kidneys to break down but a vegan diet is more alkaline and much easier on our already struggling kidneys! Typically with my disease by 30 years old you are on blood pressure medications, I am 36 and use no medications but a healthy vegan diet, low sodium and exercise! My nephrologists love me and wish all their patients listened to them!
