Cutting Salt May Lower Blood Pressure as Much as Medication

Reducing daily salt intake by just one teaspoon, equivalent to approximately 2,200 milligrams of sodium(钠), can lead to a blood pressure drop comparable to that achieved with prescription antihypertension (抗高血压) medication, reveals a recent study. Conducted on 213 individuals aged 50 to 75, the research included participants both on and off blood pressure medication. Regardless of their initial measurements, all groups experienced a(n)     1     reduction in blood pressure after a week on a low-sodium diet.

The study     2     the common notion that only those not taking medication benefit from salt reduction. Notably, the blood pressure decrease observed was similar to the effect seen when individuals start hypertension medication. The investigation aims to shed light on how excess salt raises blood pressure, aside from the conventional theory of increased water retention causing hypertension.

While sodium is     3     for bodily functions, humans, evolutionarily did not     4     to a high-sodium diet. The average daily sodium intake in the U.S. is around 3,400 milligrams, mainly sourced from     5     and restaurant foods, exceeding the recommended 2,300 milligrams by the FDA. Encouraging people to reduce salt intake proves challenging and experts suggest     6     to lower-sodium options instead of mere reduction. One proposal is transitioning from regular sodium chloride to a blend of 75% sodium chloride and 25% potassium chloride, a form of salt     7     in health food stores.

Changing dietary habits presents a puzzle, but historical precedents, like the introduction of iodized (含碘的) salt in1924 to combat pediatric goiters (儿科甲状腺肿), show that     8     shifts are possible.

Although potassium-supplemented (含钾的) salt may not be mainstream yet, it could become a future staple (基本食物) for those aiming to lower sodium intake. For now, cooking at home and     9     for lower-sodium remain practical     10     for individuals mindful of their salt consumption.
