Sulfates in Lacto-Ovo Vegetarians
There is not much research on vegans and kidney disease, and the VeganHealth.org 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.”
