A diet high insaturated fats increases a person’s riskof 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 theUnited States because consumption of red wine is higher in France. Thedifference in regular red-wine consumption has been narrowing, but no similarconvergence in heart-disease rates has occurred.Which of the following, if true, most helps to accountfor the lack of convergence noted above?
A. Consumption of saturated fats is relatedmore strongly to the growth of fatty deposits on artery walls, which reduceblood flow to the heart, than it is to heart disease directly.
B. Over the past 30 years, per-capitaconsumption of saturated fats has remained essentially unchanged in the United States but has increased somewhat in France
.C. Reports of the health benefits of red winehave led many people in the United States
to drink red wine regularly.D. Cigarette smoking, which can also contributeto heart disease, is only slightly more common in Francethan in the United States
.E. Regular consumption of red wine is decliningdramatically among young adults in France
, and heart disease typicallydoes not manifest itself until middle age.如果是B，因为因为食物中的FAT增加，所以与喝红酒减少的抵消，因此没怎么变
如果是D，他因导致与喝红酒的效果抵消，所以gap没变
