This paper showed higher sodium intake was related to lower blood pressure.

Over the 16-year follow-up period, the researchers observed that the participants who consumed under 2,500 milligrams of sodium each day had higher blood pressure than those who consumed higher quantities of sodium.

The results seem counterintuitive. As the authors write: "While we expected dietary sodium intake to be positively associated with both SBP [systolic blood pressure] and DBP [diastolic blood pressure], the opposite was found."

Sounds like a misleading study omitting the reason why a group of people would be on a sub-2500 mg sodium diet in the first place.

Standard American Diet is around 3400 milligrams of sodium a day.

The 2500 milligrams they mention in their study is essentially what the normal DASH diet recommends. DASH stands for “Dietary Approaches to Stop Hypertension”. It’s a salt level recommended for normal people in order to prevent hypertension.

There is a stricter, lower salt version of the DASH diet aiming for 1500 milligrams. People on that low of a sodium diet will be people who already have high blood pressure.

It’s the same “counterintuitive” reason why people on a sub 2000 calorie diet would be fatter than those eating more calories than that.
