And he says salt has other biological effects. He says calling for reductions in the national diet could have good effects, but it could also have harmful results. He says there is not enough evidence either way.
Another critic is David McCarron, a nutrition and kidney disease expert at the University of California, Davis. He and his team looked at large studies of diets in thirty-three countries. They found that most people around the world eat about the same amount of salt. Most of them eat more salt than American health officials advise.
Doctor McCarron says the worldwide similarity suggests that a person’s brain might decide how much salt to eat.
Both Doctor McCarron and Doctor Alderman have connections to the Salt Institute, a trade group for the salt industry. Doctor Alderman is a member of an advisory committee. But he says he receives no money from the group. Doctor McCarron is paid for offering scientific advice to the Salt Institute.
