Food-based strategies to prevent
micronutrient malnutrition were
often overlooked in the past as
governments, researchers, the donor
community and health-oriented
international agencies sought
approaches that had rapid start-up
times and produced quick results.
2006
2
Micronutrient deficiencies hinder
both national economic
development and the development
of individual human potential.
Because children are frequently
the victims of this deficiencies,
failure to overcome micronutrient
malnutrition in a sustainable
fashion jeopardizes a nation's
future.

Studies on diets of young children indicate that the
care givers make no specific attempts to include
GLVs in the diets of their children.
There are very few
studies that have
looked into the
acceptability of
recipes modified with
different GLVs and
assessed their
impact on very young
children, although
there is no dearth of
recipes per say.

Food, fortification, one of the food-based
strategies has the potential for wide
population coverage and can involve a
combination of micronutrients.
Nutrition education as a component of
food-based strategies.
Adoption of food-based strategies can
make possible redirection of funds

and social welfare to other developmental

Food based strategies are culturally
acceptable and feasible to implement.
Foster the development of
environmentally sound food
production systems.
Promote self-reliance and

Drumstick leaves
Out of all green leafy
vegetables available,
drumstick leaves
(Moringa Oleifera)
contains 23791.91mcg
total carotene and
highest β-carotene
content 16165.33 mcg/
100gm FW and can be
a suitable protocol for
dietary
diversification/improve
ment strategy especially
to eradicate vitamin A
deficiency.

Apart from β-carotene content they
are also a good source of ascorbic
acid, calcium, phosphorus, vitamin E
and has low levels of oxalates.
They are a rich source of protective
nutrients essential for healthy vision,
bones, blood and skin.
The are also rich in various
polyphenols, which act as antioxidants
and are recommended for protecting
against CVDs.

EMERGING PROBLEMS
Epidemiological studies
have consistently shown
that high intakes of
vitamin A/ carotenoids
present in fruits and
vegetables are associated
with reduced risk of
several chronic diseases,
including cardiovascular
disease, age-related
macular degeneration and
some cancers.
2006

Solution ???
Total phenols 383.87 ± 19.09 mg/g
The flavonoids identified were Kaempferol, Quercetin and
3’,4’- diOMe quercetin.
The phenolic acids identified were chlorogenic acid,
melilotic acid, vanillic acid, o –coumaric acid and
p-coumaric acid.
The glycoflavone identified in drumstick leaves was
4’-OMe Vitexin.
2006

GLVs are however, perishable and thus
alternative preservation strategies like
adding them in the dry form were assessed.
Blanched and sulphited and shade dried
drumstick leaves (DDL) retained 50% of the
beta-carotene after three months of storage
and when incorporated in three traditional
(gujarati) recipes (muthia, dal soup, dhebra)
were found to be highly acceptable.
2006
13
The South Indian dals and soups made from
drumstick’s pods have a unique flovour.
Dried and roasted drumstick seeds taste like
groundnuts.
The dried leaves, root and seeds are used as
condiments
in traditional cooking. 14
2006
Medicinal properties
Juice is used for treating insect bites and rheumatism.
Leaf paste has healing properties when applied to
wounds.
Seed oil is used to treat gout and flowers are used as
a tonic.
15
2006
The tender drumstick leaves are
popular leafy vegetable in southern
parts of India and is added to many
dishes.
For those who appreciate it, the
drumstick’s
subtle
flavour
is
unsurpassable.
However many have not acquired a
taste for this very nutritive vegetable.

However, these leaves are grossly
underutilized ……………

One serving of recipes (30gm) could
incorporate a maximum of 20gm fresh
drumstick leaves

All the three recipes were found to be acceptable by
the panel of judges with an overall composite score
ranging from 3.06-3.53.
The drumstick leaves recipes were micronutrient rich
and could provide ~ 330 RE vitamin A.
As per the International RDI of vitamin A for adult
and pregnant women, they could meet 55-66% RDI
of vitamin A for Indian.
Thus these recipes should be promoted in the
National Feeding Programme to enhance the vitamin
A status of the populations.

Feasibility
and acceptability of introducing
dehydrated drumstick leaves, (DDL)
(Moringa oleifera), into the salty recipes
provided by the supplementary food (SF)
component of the Integrated Child
Development Scheme (ICDS) along with
nutrition communication (NC).
2006
24
Integrated approach was adapted which included
comprehensive training sessions for the staff of
the ICDS and Non-government organization
(NGO) involved in the SF preparations.
The present study gives an insight to the present
health system, wherein health systems research
(HSR) is used to assess effectiveness of the
training and education which are the
cornerstones of programmes for nutritional
improvement.
2006
25
The present study concentrated on training the human
resources based on their functional classes which gave a very
positive result. The functional classes were:
Those concerned with planning policies at sectoral levels –
local ICDS authorities.
Those concerned with implementation and administration
(including surveillance)- interagency coordination (nongovernment organization) involved in food production and
distribution.
Those concerned with the delivery of food and nutrition
services, coordination of services at the local level and by
personnel in each community – ICDS supervisors,
anganwadis workers and helpers.

Nutrition education is an important measure to
encourage a desirable dietary pattern and stimulate
effective demand for appropriate food.
Studies on communicating the aspects of nutrition and
health have justified the need of an integrated
approach of NHE and intervention.
2006
28
Integration of Nutrition communication along with the
introduction of unconventional DDL, into the ICDS-SF,
was feasible and can be endeavored for a longer duration in
the existing national programmes.
