“When considering cancer and coronary heart disease5 prevention， there is no evidence that pure fruit and vegetable juices are less beneficial than whole fruit and vegetables，” the researchers said. The researchers added that the positioning of juices as being nutritionally inferior to6 whole fruits and vegetables in relationship to chronic disease development is “unjustified” and that policies， which suggest otherwise about fruit and vegetable juices， should be re-examined.
The researchers who authored the paper suggest that more studies in certain area are needed to bolster their findings. “Although this independent review of the literature is not designed to focus on any particular 100 percent juice， it does go a long way7 in demonstrating that fruit and vegetable juices do play an important role in reducing the risk of various diseases， especially cancer and cardiovascular disease，” said Sue Taylor. Her opinion is in agreement with8 the Juice Products Association，9 a non-profit organization not associated with this research. She added that appropriate amounts of juices should be included in the diet of both children and adults， following guidelines established by leading health authorities. Taylor also points to a large epidemiological study， published in the September 2006 issue of the Journal of Medicine， which found that consumption of a variety of 100 percent fruit and vegetable juices was associated with a reduced risk for Alzheimer’s disease.10
In fact(事實(shí)上)， that study found(發(fā)現(xiàn)) that individuals(個(gè)人) who drank(飲用) three or more servings (份)of fruit and vegetable juices per week (每周)had a 76 percent (與選項(xiàng)B中數(shù)字3/4呼應(yīng))lower(更低的) risk of developing Alzheimer’s disease(早老性癡呆病) than those who drank juice less than(少于) once per week(每周). The study was published in the International Journal of Food Science and Nutrition11 (2006).
答案相關(guān)句(第五段第一句)說(shuō)：每周喝3-4份蔬菜汁和果汁的人與每周只喝蔬菜汁和果汁不到一次的人相比，前者患早老性癡呆病的危險(xiǎn)性下降了76%，76%就是3/4，因此B項(xiàng)是正確答案。A項(xiàng)是高出23%，c項(xiàng)是基本不喝的人的123%，D項(xiàng)是基本不喝的人的176%，均不正確。
