The Cost of Nutritious Diets: New Price Indexes Reveal Changes in Affordability of Foods and Nutrients
1. Results from
Changing Access to Nutritious Diets in Africa and South Asia (CANDASA)
funded by UKAid and the Bill & Melinda Gates Foundation
http://sites.tufts.edu/candasa
IFPRI Policy Seminar, 29 May 2019
The Cost of Nutritious Diets:
New Price Indexes Reveal Changes in
Affordability of Foods and Nutrients
2. Why measure the cost of nutritious diets?
• Food environments are changing rapidly,
in both urban and rural areas
– from own-production to use of markets
– from generic commodities to branded, packaged foods
– shifts in cost of starchy staples, milk, eggs, meat, fruit & veg
– shifts in earnings, towards more choice among affordable foods
• Food prices are collected to measure inflation and poverty
– economists have used prices for the cost of calories & food demand
– aid programs have used prices to recommend a least-cost diet
– we use prices to study food systems, for access & affordability
• Analysis of diet costs can guide intervention
– each CANDASA researcher will share findings from their work
– discussion today is at project midpoint, from Jan. 2018 to June 2020

8. New price indexes account for nutritional needs
Cost of Recommended Diets
• Based on food-based dietary guidelines
• Food groups & servings (g) per day
• Choose foods that meet recommendations
at lowest total cost
Cost of Nutrient Adequacy
• Lowest cost of meeting calorie, macronutrient, and
micronutrient needs
• Specify quantity of each nutrient
• Choose foods that meet needs at lowest total cost

Using household data to infer individual adequacy and cost
13. Cost per day depends on age, sex & maternity status
Women and children need fewer calories
than men, but typically need more
micronutrients per calorie.
• Adolescent girls need more calcium and
phosphorus;
• Breastfeeding calls for more folate,
protein, vit A, especially for older women
(>31);
• Older men need more vitamins B6, B12,
C and E;
• Children 1-3 years need the most lipids.
Different needs translate to different costs to meet all
daily nutrient needs.
14. Households are consuming a diet that, at best,
meets 70-80% of total nutrient needs.
Do households have enough food to meet nutrient needs?
We use household survey data to compare
consumption to needs.
• To aggregate needs to the household
level, we use two sharing scenarios and
individual nutrient density needs.
Sharing food: everyone eats the same diet.
• Nutrient density per nutrient, defined by
the member with the highest nutrient-per-
calorie need;
• Eaten per person in proportion to energy
needs.
Targeted diets: each person eats a separate
diet tailored to individual needs.
• Households are a sum of individual
needs.

stable or rising
• Real wages have grown sharply
Not all Ethiopians earn wages
• But unskilled wages are a proxy for
incomes of the poor:
➢ Correlated with HH spending
➢ A “reservation” or fallback wage

What’s the net result?
• Since 2011, the cost of nutritious diets
has fallen from >30% to <20% of wages
• But the cost of calories has fallen more,
from over 10% to only 5% of wages
• Attention is shifting from calories to
nutrients, and the relative cost of
healthier diets
Counterfactual:
• If nutrient costs had stayed constant as
wages rose, nutritious diets would now
cost just 11% of wages
Improved affordability shifts attention to food choice

26. How costly is the recommended diet relative to wages?
Diet costs are a larger
fraction of wages for women
• 70-80% of women’s wage
• 50-60% of men’s wage
Highly unaffordable:
• Costs for non-food expenses
and other family members?
• Volatile!
But some improvement:
• wages ↑ & diet cost ↓ since
2007, but more so for men

Ghana now has the most interest among government officials
29. • There is government interest,
but support is needed
Policy dialogue for use of new price indexes in Ghana
• To help introduce new metrics, an informal “Nutritious Food Prices Analysis Support Group” to be hosted at
the University of Ghana’s Institute for Statistical, Social & Economic Research (ISSER)
• This is to allow government statistical officers to meet regularly with local economists and other stakeholders,
before and after release of new data, to discuss the significance and interpretation of each indicator
• Meetings will begin mid-2019
• Since 2016 IANDA/CANDASA
has worked with Ghanaian
authorities (GSS, MoFA) to
help officials use the new price
indexes within their routine
food price monitoring

31. The cost of nutritious diets: what have we learnt so far?
What do price indexes for nutritious diets reveal?
1) Total cost per day depends on the combination of all needed foods and nutrients
a) Total cost exceeds earnings for the poorest, who need aid to afford a healthy diet
b) Relative cost among affordable foods varies widely, influencing food choice
2) Food system changes could make healthier diets more affordable for all
a) Reduce seasonality in cost of perishable foods
b) Reduce spatial variation by region and type of market
3) Price monitoring could help guide policies and programs
a) Data collection: product range, frequency, representativeness, quality
b) Results dissemination: raise the profile of nutritional affordability metrics
c) Policy & program decision-making: use of data to guide intervention
32. The cost of nutritious diets: what can we do in the future?
There is so much more for CANDASA & others to do…
1. Use additional dietary guidelines, for more countries & population groups
2. Refine cost of nutrient adequacy, with more on food composition & needs
3. Improve price information, for more diverse foods, locations and time periods
4. Expand analysis to cost of unhealthy foods and dietary patterns
5. Expand use of wage & income data (as in India & Ethiopia)
6. Compare least-cost to actual diets, to understand divergence
7. Analyze impact of local production, storage & trade on diet costs
8. Analyze impact of diet costs on nutrition and health outcomes
33. The cost of nutritious diets: what can we do in the future?
Encourage uptake of nutritious-food price indices
• Every national statistical agency collects food price data
• Many agricultural and food agencies collect food price data
• Yet almost none of them monitor the cost of nutrition!
How do we catalyze that change?
• Capacity strengthening projects
• Institutional collaboration: nutrition/health ministries and stats agencies/agricultural
ministries (e.g. get prices in SUN movement, multisectoral nutrition strategies)
• Make price data publicly available!
