• Poor diets a root cause of
undernutrition & overnutrition
• Healthy foods often perishable,
non-tradable and expensive
• Healthy diets expensive in Asia
• Policy implications?
• Raise incomes?
• Lower diet costs?
• Nutritional education?
3. What is a good diet?
• Broad agreement on principles, but
not necessarily on details
• Many countries have food-based
dietary guidelines (FBDGs):
• Diversity/balance across food groups
• High intake of fresh fruit/vegetables,
whole grains, legumes/nuts
• Low sodium, oils/fats, sugar, red meat
• First global reference diet released
this year: EAT-Lancet
• Decrease disease risk in adulthood
• However, infants & young children
benefit from animal-sourced foods:
• Stunting reduction
• Cognitive development
4. Food affordability or nutritional knowledge the key constraint?
Why should we care about dietary costs?
Diet affordability
(ratio of income to diet cost)
Dietary quality Cost of healthy diet
(fuzzy!)
5. Why should we care about market prices?

Sources of food consumption in rural Bangladesh
Own farm
Markets
• Even rural consumers mostly depend on markets for consumption
6. How expensive are (un)healthy foods?
• Can answer this question with relative caloric prices
• e.g. cost of 1 egg calorie relative to 1 starchy staple calorie
• Why price foods in caloric terms?
• Calories essential for survival, activity & averting hunger
• Why measure prices relative to staples?
• Measures cost of diet diversification in a comparable way
• Data: 2011 International Comparison Program (ICP)
• Prices for 657 standardized food products in 176 countries
• Series of maps:
• light = cheap relative to cereals
• dark = expensive relative to cereals

16. Why are some foods expensive?
Less perishable More perishable

legumes/nuts, dried
fish & fruit
sugar, oils, soft
drinks, snack foods
More expensive
Fortified infant
cereals
Most fruit,
vegetables, milk,
eggs, meat, fresh fish
• Many fresh and nutrient-dense foods are perishable
• Limits opportunities for long-distance trade
• Prices mostly determined by local supply & productivity
17. How costly are healthy diets in Asia?
$1.90/day
Poverty line
• We used the same ICP price data to estimate cheapest daily
cost the EAT-Lancet diet …
Around 1 billion people cannot
afford EAT-Lancet in Asia
18. How costly are healthy diets in rural India?
• Use monthly data on prices & wages in rural India, 2001-11
• Diet costs rose from 2001, but wage growth faster
• Diet costs as share of wages fell by 5-6 points
• But ….
• Diets as a share of safety net (NREGA) wages rose
• Most rural Indians could not afford a healthy diet in 2011

20. What should be done, where and when?
Income growth is essential for the poor
Incomes of the poor are a long way from meet diet costs
Economic growth must be pro-poor (track with wages?)
Safety nets can reduce dietary gaps in the short run
But cash or food?
Should food be staples or nutritious foods?
Safety net programs should start costing nutritious diets!!!
Investment in agriculture, and for agriculture
Fresh nutrient-dense foods highly perishable, so limits to trade
Diversification and productivity growth can drive down prices
Essential to improve value chains for perishable foods
Policy implications
21. What about improving nutritional knowledge?
For poor populations
Focus on young children and mothers
Potentially combine with cash transfers (e.g. TMRI project)
For emerging middle classes, with rising incomes
Nutrition education critical for obesity/NCD prevention
Especially important for school-age populations:
Forming life-long dietary habits
Vulnerable to aggressive marketing, social pressures
Focus on encouraging healthy diets and cooking practices
Support with proactive legislation: e.g. food labelling
Major challenge: improve nutritional knowledge at scale!
Policy implications
