A study from Columbia University Medical School shows that salt restriction raises blood sugar and insulin levels, while salt loading lowers them.

Twenty-one people with high blood pressure were given four week periods of salt loading and salt restriction. Salt restriction caused a higher rise in blood sugar levels after both heathy people and diabetics were fed a sugar load. Salt restriction caused a higher rise in insulin levels in both diabetics and non diabetics. For years doctors have told people to restrict salt, even those who do not have high blood pressure. Most competitive athletes and serious exercisers know that they cannot recover from hard exercise without taking lots of salt. It is time for the doctors to tell their patients that salt restriction is highly controversial and that many doctors take lots of salt themselves and tell their patients to do the same. You should check with your doctor to see whether salt restriction will help or harm you. See report #D222.
