Should consumers who are concerned about autoimmune disease switch to a low-salt diet, even before tests in humans have been done?
"If I had an autoimmune disease, I would put myself on a low-salt diet now," Hafler said. "It's not a bad thing to do. But we have to do more studies to prove it."
O'Shea agreed. "But the extent to which salt is important, I think we don't know. These papers show it experimentally, but we still can't be sure," he said.
