问题 Which of the following is the main topic of the passage? [br] According to the passage, which of the following is NOT true about the function and nature of slat?
选项 A、It is composed of sodium and chloride.
B、It helps the body to keep fluid substance.
C、Too much salt consumed can lead to high blood pressure.
D、It is the direct cause of heart diseases.
答案 D
解析 推断题。根据第一段第四、五句“It makes the body retains fluids．．．heart disease and stroke”可知，钠使人体保留体液，体液保留量的增长可提高总血容量，从而导致血压升高。在食盐摄人不受限制的地区，很多人患上慢性高血压，而慢性高血压又是导致心脏病与中风的主要因素。由此可见，食盐是导致心脏病的间接因素。
