Columnist: People should avoid using a certain artificial fat that has been touted as a resource for those whose medical advisers have advised them to reduce their fat intake. Although the artificial fat, which can be used in place of fat in food preparation, has none of the negative health effects of fat, it does have a serious drawback: it absorbs certain essential vitamins, thereby preventing them from being used by the body.
In evaluating the columnist's position, it would be most useful to determine which of the following?
Whether increasing one's intake of the vitamins can compensate for the effects of the artificial fat
Whether the vitamins that the artificial fat absorbs are present in foods that contain the fat
Whether having an extremely low fat intake for an extended period can endanger the health
Whether there are any foods that cannot be prepared using the artificial fat as a substitute for other fats
Whether people are generally able to detect differences in taste between foods prepared using the artificial fat and foods that are similar except for the use of other fats
果因
不应该服用人工fat
∵它会吸收必需维他命，阻碍身体吸收
评估
A、是否多吃维他命就可以弥补服用人工fat的亏损，如果可以，那服用人工fat没什么大不了，补一补就好了；不可以，说明人工fat这种危害神仙难救啊
B、是否人工fat吸收的维他命出现在fat里，无关；出不出现，和人吃不吃，身体吸不吸收都无关
C、fat摄入与健康的联系，与维他命无关
D、是否存在食物不能用人工fat代替天然的，同上无关
E、人们是否能尝出人工与天然fat的区别，同上无关
