1Research shows that in developed countries, more affluent and educated people tend to consume higher-quality
2diets-including more fruits and vegetables, fish and whole grains. On the contrary, economically disadvantaged people
3report diets that are nutrient-poor and energy-dense. They are less likely to have food-purchasing habits that conform
4to public health recommendations. These dietary differences are often accompanied by higher rates of obesity and
5diabetes among lower-income people. This relationship between social class and diet quality and health is extensively
6documented. However, the research does not explain why this is the case—a question that has significant implications for
7designing effective policies and initiatives to improve diets and prevent chronic diseases. Public-health initiatives to
8promote healthy diets often focus on providing nutrition education and recipes (食谱). These approaches, however, often
9presume less food literacy (i.e. food knowledge and skills) among low-income people. Are unhealthy diets really the
10result of poor choices, limited food skills and knowledge? Research suggests that adults in food-insecure households are
11just as likely as those in food-secure households to adjust recipes to make them more healthy. They are also just as
12proficient in food preparation and cooking skills. There is no indication that increasing food skills or budgeting
13skills will reduce food insecurity. Instead, disadvantaged groups are constrained by their economic, material and social
14circumstances. For example, low income is the strongest predictor of food insecurity in Canada, where one in eight
15households experiences insufficient access to nutritious foods. It's well-established that food prices are an important
16determinant of food choice. Low-income households report that they find it difficult to adopt dietary guidelines because
17food prices are a barrier to improving their diets. When researchers estimate the cost of diets people actually eat,
18higher-quality diets are typically more costly. While this may be so, it does not, in itself, prove that healthy diets
19are necessarily more expensive or cost-prohibitive. After all, not all socioeconomically disadvantaged people consume
20poor diets. We can easily think of a number of foods and recipes that are both inexpensive and nutritious. The internet
21is full of recipes for "eating well on a budget.”
