问题     Research shows that in developed countries, more affluent and educated people tend to consume higher-quality diets—including more fruits and vegetables, fish and whole grains. On the contrary, economically disadvantaged people report diets that are nutrient-poor and energy-dense. They are less likely to have food-purchasing habits that conform to public health recommendations.
    These dietary differences are often accompanied by higher rates of obesity and diabetes among lower-income people. This relationship between social class and diet quality and health is extensively documented. However, the research does not explain why this is the case — a question that has significant implications for designing effective policies and initiatives to improve diets and prevent chronic diseases.
    Public-health initiatives to promote healthy diets often focus on providing nutrition education and recipes (食谱). These approaches, however, often presume less food literacy (i.e. food knowledge and skills) among low-income people. Are unhealthy diets really the result of poor choices, limited food skills and knowledge?
    Research suggests that adults in food-insecure households are just as likely as those in food-secure households to adjust recipes to make them more healthy. They are also just as proficient in food preparation and cooking skills. There is no indication that increasing food skills or budgeting skills will reduce food insecurity.
    Instead, disadvantaged groups are constrained by their economic, material and social circumstances. For example, low income is the strongest predictor of food insecurity in Canada, where one in eight households experiences insufficient access to nutritious foods.
    It’s well-established that food prices are an important determinant of food choice. Low-income
    households report that they find it difficult to adopt dietary guidelines because food prices are a barrier to improving their diets.
    When researchers estimate the cost of diets people actually eat, higher-quality diets are typically more costly.
    While this may be so, it does not, in itself, prove that healthy diets are necessarily more expensive or cost-prohibitive. After all, not all socioeconomically disadvantaged people consume poor diets.
    We can easily think of a number of foods and recipes that are both inexpensive and nutritious. The internet is full of recipes for "eating well on a budget."
What does the author suggest disadvantaged people do to improve their health?
选项 A、Adopt a positive attitude towards dietary guidelines.
B、Choose diets that are both healthy and affordable.
C、Make sure to purchase healthy foods on the internet.
D、Change their eating habits and consumption patterns.
答案B
解析 题目询问作者建议弱势群体如何改善健康状况。最后一段指出，我们轻轻松松就可以想到许多既便宜又有营养的(inexpensive and nutritious)食物和食谱；网上到处都有“既省钱又吃得好(eating well on a budget)”的食谱。由此可见，作者是在建议他们选择既健康又负担得起的饮食，故选B项。
