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 would help improve food security among the disadvantaged groups in Canada?
选项 A、Teaching them budgeting skills.
B、Increasing their food choices.
C、Enabling them to have more access to nutritious foods.
D、Taking more effective measures to increase food supplies.
答案C
解析 题目询问怎样做有利于改善加拿大弱势群体的饮食保障问题。根据第5段第2句可知，在加拿大，低收入是饮食没有保障的最大原因，导致一些家庭无法获得足够的营养的食物。换句话说，要改善饮食保障，就应该给他们提供有营养的食物，故选C项“使他们有更多的机会获得有营养的食物”。
