   When it comes to eating smart for your heart, stop thinking about short-term fixes and simplify your life with a straightforward approach that will serve you well for years to come.
   Smart eating goes beyond analyzing every bite of food you lift to your mouth. "In the past we used to believe that 【C1】______ amounts of individual nutrients were the key to good health," says Linda Van Horn, chair of the American Heart Association’s Nutrition Committee. "But now we have a different 【C2】______ of healthy eating and the kinds of food necessary to prevent not only heart disease but disease in general," she adds.
   Scientists now 【C3】______ on the broader picture of the balance of food eaten over several days or a week rather than on the number of milligrams of this or that 【C4】______ at each meal. Fruits, vegetables and whole grains, for example, provide nutrients and plant-based 【C5】______vital for good health.

Without a 【C10】______, each of the small decisions you make in this realm can make a big impact on your health in the years to come.
【C2】
选项
答案O
解析 空格前为不定冠词a和形容词different，因而空格处需填入名词单数形式。句中转折词But表明．空格所在句语义与前一句存在转折。上一句讲的是人们过去的饮食观念(we used to believe that)，因而空格所在句讲的是人们现在的饮食观念。词库中名词understanding填入句中，语义通顺：但现在我们对健康饮食有了不同的理解，故选O项。文章讲的是人们饮食观念的变化，expectation“期待，预期”填入句中，语义不通，故排除H项。
