Complementary protein nutrition
• Pulses’ protein rich in lysine but
deficient in S-containing amino acids
• Cereals’ protein deficient in lysine but
rich in other AA
• Over all nutritional efficiency of cereal
rich diet thus enhanced when mixed in
the ratio of 1 part of pulses to 8 parts of
cereals
• Meat replacement, lower C & H20
footprint
![Page 8: Pulses strategy for sustainable food and nutritional security in](https://reader033.vdocuments.net/reader033/viewer/2022051712/586d3a391a28ab95168b46ca/html5/thumbnails/8.jpg)
Other nutritional benefits of pulses
• Rich in mineral nutrients (Mg, K, P, Zn, Fe)
• Rich in dietary fiber
• Rich in bioactive compounds that reduce
risk of chronic diseases
• Positive effect on prevention of non-
communicable diseases such as obesity,
diabetes, coronary conditions and cancer
“Pulses are future of food”

Multiple uses of pulse crops in different
production systems and gender dimension
• Seeds consumed as
green or dry grains;
also leaves sometimes
used as vegetable.
• In many systems,
considered as women’s
crops, providing
important source of
income & family’s
nutritional needs.

Production vs. demand & per capita
availability of pulses in SA region
• Domestic production lagging behind the
demand because of population growth
• Per capita availability falling well below the
WHO recommended consumption level with
serious nutritional consequences
• Regional deficit being partially made up by
imports from outside the region
• Some intra-regional trade helpful in meeting
local deficit
• Major cause of deficit is low yield
![Page 16: Pulses strategy for sustainable food and nutritional security in](https://reader033.vdocuments.net/reader033/viewer/2022051712/586d3a391a28ab95168b46ca/html5/thumbnails/16.jpg)
Pulses strategy for sustainable food
and nutritional security in SA region
• SA region largest consumer of pulses
in the world
• Growing demand can not be met by
imports, also because of specialty of
types of pulses needed
• Therefore, sustainable increase in
domestic production within the region
is the only course
![Page 17: Pulses strategy for sustainable food and nutritional security in](https://reader033.vdocuments.net/reader033/viewer/2022051712/586d3a391a28ab95168b46ca/html5/thumbnails/17.jpg)
