Driving demand for the
utilization of
underutilized legumes
for health, nutrition and
sustainable food systems
in Africa
1
THE 36TH ACADEMIC LECTURE SERIES
Presented by Dr. Florence Adetutu Udofia
OUTLINE

INTRODUCTION
3
▪ Underutilized legumes are leguminous
crops that have been known, grown, and
used by local communities, but they have
not received the same level of attention in
mainstream research, markets, policy,
processing, and consumption as major
crops.
▪ The more urgent question is: If the
evidence is already strong, why does
Africa still face hunger, poor diet quality
and rising diet-related diseases?
Africa’s irony: rich legumes, rising health burden

Projected hunger by 2030:
512M globally; ~60% in
Africa
Diabetes in Africa:
25M → 60M adults by 2050
The missing link is demand
5
• People will not eat a food only because it is
nutritious.
• Demand means making underutilized legumes
wanted • trusted • affordable • convenient
• visible • health-linked
6
Five demand levers to add to the presentation
• These levers turn nutrition evidence into repeated purchase, household use and
policy support.
➢Product convenience: Ready-to-cook packs, flour, snacks, porridge mixes and blends.
➢Price and access: Local sourcing, fair margins and products that fit ordinary household
budgets.
➢Taste and culture: Recipes that respect familiar meals while improving preparation
methods.
➢Health credibility: Clear, evidence-based messages on protein, fibre, minerals and diet
quality.
➢Institutional demand: Schools, hospitals, food programs, processors and public
procurement

Evidence-based health promotion can drive demand
8
Health promotion should
answer:
• Why is it good for my
family?
• How do I prepare it
quickly?
• How often can I use it?

This is where SUL can lead: connect researchers, processors, health educators, policy makers and
consumers
Conclusion: the next frontier is demand
• Underutilized legumes are not short of value. They are short of visibility,
convenience, and sustained demand.
• Researchers should package evidence into simple, useful messages.
• Processors should develop attractive, safe and affordable products.
• Health promoters should link legumes to everyday nutrition and disease prevention.
• Policy makers should use procurement standards and incentives to grow markets.
