“…Previous studies from the UK ( 4 , 8 , 9 ) , Spain ( 3 , 10 ) , France ( 6 , 11 , 12 ) , the Netherlands ( 13 ) and the USA ( 5 , 14 – 18 ) all suggest that healthier diets cost more. Typically, higher-quality diets are characterised by higher intakes of whole grains, lean meats, fruits and vegetables, and by lower intakes of fats and sugars, and refined grains ( 19 , 20 ) .…”

Studies in many Western countries have consistently shown that monetary diet cost is positively associated with diet quality, but this may not necessarily be the case in Japan. This cross-sectional study examined the nutritional correlates of monetary diet cost among 3963 young (all 18 years old), 3800 middle-aged (mean age 48 years) and 2211 older (mean age 74 years) Japanese women. Dietary intakes were assessed using a comprehensive self-administered diet history questionnaire for young and middle-aged women and a brief self-administered diet history questionnaire for older women. Monetary diet cost was estimated using retail food prices. Total vegetables, fish and shellfish, green and black tea, white rice, meat, fruit and alcoholic beverages contributed most (79–89 %) to inter-individual variation in monetary diet cost. Multiple regression analyses showed that monetary diet cost was negatively associated with carbohydrate intake, but positively with intakes of all other nutrients examined (including not only dietary fibre and key vitamins and minerals but also saturated fat and Na) in all generations. For food group intakes, irrespective of age, monetary diet cost was associated inversely with white rice and bread but positively with pulses, potatoes, fruit, total vegetables, fruit and vegetable juice, green and black tea, fish and shellfish, and meat. In conclusion, in all three generations of Japanese women and contrary to Western populations, monetary diet cost was positively associated with not only healthy dietary components (including fruits, vegetables, fish and shellfish, dietary fibre, and key vitamins and minerals), but also less healthy components (including saturated fat and Na).

“…More recently, a minimal allotment of 7.50 US$ per week was proposed by An and colleagues as suitable to entail an evolution of the purchasing behaviour [22]. Besides, a study performed in France among a similar population showed that about 20% of the households (called "positive deviants") developed strategies allowing them to purchase healthier food than others, without increasing their food budget [63].…”

Impact of fruits and vegetables vouchers on food insecurity in disadvantaged families from a Paris suburb

et al. 2019

Background: Social inequalities in nutrition lead a high number of families to struggle with food insecurity, even in developed countries. We aimed to assess the impact of fruits and vegetables vouchers on food security among disadvantaged households from a Paris suburb. Methods: We used a pre-post assessment design. Families answered face-to-face questionnaires on food consumption and food security status before and after a randomly assigned intervention. Households in the intervention group received vouchers to buy exclusively fruits and vegetables over one year. Both intervention and control groups benefitted from nutritional education through workshops performed by dieticians during the study period. The Household Food Security Module (HFSM) was used to assess food security status of households at inclusion. Food Insufficiency Indicator (FSI) was used to assess food security at inclusion and follow-up. Evolution of FSI on both groups was evaluated using McNemar test. Results: Among the 91 families included between May 2015 and May 2016, 64 completed the post assessment questionnaire. At inclusion, 68.3% of families were experiencing food insecurity and 78.1% were experiencing food insufficiency. No association was found between food consumptions and food security status. After one-year follow-up, the prevalence of food insufficiency was significantly decreased in the intervention group (61.8%, with p value = 0.03), and unchanged in the control group. Conclusion: In this pilot study, food insufficiency was significantly decreased in families receiving vouchers for fruits and vegetables over a one-year period.

“…However, there are a number of papers that argue (using price per gram or per serving) you can eat healthily on a limited budget (17,18) . Using the cost of the diet, some observational studies found that certain population groups can achieve higher-quality diets at a lower cost than other groups (19,20) . Others report that if foods are carefully selected it is possible to consume a low-cost diet relatively low in energy density and high in nutrient density (21)(22)(23) but this requires a motivated and knowledgeable shopper (18) .…”
