A diet high in saturated fats increases a person's risk of developing heart disease. Regular consumption of red wine reduces that risk. Per-capita consumption of saturated fats is currently about the same in France as in the United States, but there is less heart disease there than in the United States because consumption of red wine is higher in France. The difference in regular red-wine consumption has been narrowing, but no similar convergence in heart-disease rates has occurred.
Which of the following, if true, most helps to account for the lack of convergence noted above?
Consumption of saturated fats is related more strongly to the growth of fatty deposits on artery walls, which reduce blood flow to the heart, than it is to heart disease directly.
Over the past 30 years, per-capita consumption of saturated fats has remained essentially unchanged in the United States but has increased somewhat in France.
Reports of the health benefits of red wine have led many people in the United States to drink red wine regularly.
Cigarette smoking, which can also contribute to heart disease, is only slightly more common in France than in the United States.
Regular consumption of red wine is declining dramatically among young adults in France, and heart disease typically does not manifest itself until middle age.
脂肪影响心脏病 红酒抵消该种脂肪对心脏的影响
US & Fr 脂肪摄入量相同,但Fr红酒喝得多,所以心脏病 < US
两国红酒摄入量的差距在减小,但是心脏病率却没发生变化 (解释原因)
错选D - 法国的吸烟率更高一点,吸烟也会造成心脏病 - if true,即使有红酒,红酒摄入量相似,法国心脏病率也会提高,但是没有❌ (反题目条件)
E: 前半句解释了红酒消费量趋近的原因,后半段解释了心脏病convergence的原因
