1.一項新的研究顯示，想讓心髒變得更健康，除了要減少飲食中鈉的攝入之外，美國人還應該增加一種重要礦物質的攝入，這就是許多果蔬中都含有的鉀元素。
A new study suggests that in addition to cutting the amount of sodium in their diets to improve heart health, Americans should also increase consumption of a key mineral found in many fruits and vegetables: potassium.
2.鈉是鹽的重要成分，有跡象表明它會使血壓升高，進而增加心髒病發作的風險，但至於高鈉飲食是否真的會增加心髒相關疾病發作的風險，各種研究結果卻是說法不一。
Sodium, a key component of salt, has been shown to raise blood pressure, which in turn raises the risk of heart disease, but studies have shown inconsistent results as to whether high-sodium diets actually boost the risk of heart-related problems.
