你說的最高不能超過一茶匙，不是最低不能低於那麽多。

Worried that you’re not getting enough sodium? It’s not likely. There’s no reliable evidence that eating less than 1,500 mg per day of sodium is a risk for the general population.
The body needs only a small amount of sodium (less than 500 milligrams per day) to function properly. That’s a mere smidgen — the amount in less than ¼ teaspoon. Very few people come close to eating less than that amount. Plus, healthy kidneys are great at retaining the sodium that your body needs.
