The most common means of providing dubious proof that salt causes hypertension is to compare societies that use little salt with those that use mountains of salt in their daily diets. Which group has the higher rate of hypertension? Whose blood pressure is lower? What happens when salt is introduced into a group where salt is a novelty? Does the blood pressure rise significantly? Studies of the Japanese indicate that as the world’s greatest salters, they suffer the most from hypertension. On the other hand, the simple, salt-free cuisine of several tribes in the Solomon Islands has kept older tribesmen and women from developing hypertension and high blood pressure, ailments traditionally killing their peers in America. No account is taken of the effects of inflation, recession, pollution, crime, and sundry other ills to which Americans, unlike people on primitive islands, are exposed.
