2Present Scenario of Health of Indians
- There has been a striking change in life style
and dietary habits of Indians. The population
continues to rise as does rural to urban
migration and poverty to middle class transition. - Technology manifestation have been making roads
into all corners of our country and into homes of
the all classes of Indians. - Technology have brought labor saving devices at
affordable cost which has led to steep reduction
of expenditure of energy in carrying out daily
tasks. And increasingly daily sedentary
population is beginning to see the emergence of
the so-called life style diseases-obesity,
hypertension, diabetes mellitus and
cardiovascular diseases. - However, maternal and infant mortality rate
remain high and well above to millennium
Development Goals and Anaemia in all sections of
population is at high level. Nearly one third of
infants are low birth weight and at risk of
stunting.
3- To overcome the problems of undernutrition and
overnutrition - There is need to develop value added products
from cereals and pulses. - Development and nutritional evaluation of
beta-carotene and iron rich products from
unconventional vegetables. - Development of fiber rich products.
- Development and nutritional evaluation of value
added products using medicinal plants and to test
their efficacy against blood sugar and
cholesterol level in animals and human beings. - Nutritional evaluation of underutilised foods of
India and incorpoartion in traditional diet to
improve their nutritional quality. - Nutritional evaluation of new crop verities and
preparation of value added products.
4Pearl millet
- In India, Pearl millet is the fourth most
important staple food crop after rice, wheat, and
sorghum . - India is the largest producer of pearl millet
both in terms of area - (9.1 million hectare ) and production ( 7.3
metric tones) with an average productivity of 780
kg / hectare . - The grain of pearl millet is particularly rich in
iron and zinc and has high levels of fat and
considered to have one of the best protein
quality or amino acid score as compared to other
cereals. - Inspite of greater availability, low cost and
comparatively good nutritional value, use of
pearl millet in human consumption is very low and
the major constraints which interfere in its
utilization is the presence of antinutirtional
factors in the form of phytic acid and
polyphenols.
5Sorghum (Jowar)
- India is the 2nd largest producer of sorghum .
- It is the 3rd most important cereal of India
after rice and wheat. it provides staple foods to
millions. - Jowar is nutritionally superior to rice and
comparable in many aspects with wheat. it
provides cheap staple food and is comparatively
more nutritious in terms of proteins,
carbohydrates, minerals etc., to millions of
people. - Sorghum and millets in general are rich sources
of B-complex vitamins.

9OATS
- Use of oat flour as food supplements should be
encouraged as its helps to improve the lipid
profile and could be easily included in our daily
diet in the form of chappatis it provide soluble
fiber beta-glucan , antioxidants, phytochemicals,
essential fatty acids. Gamma linolenic acids
which are otherwise or negligible in our daily
diet. - It is recommended that Oat flour should be
supplemented with the wheat flour in the ratio
of 13.
10Flaxseed
- Whole Flaxseed contains 28 dietary fibre (7
10 soluble fibre, 11 - 18 insoluble fibre).
Soluble fiber binds bile acids cholesterol and
help in their elimination from the body. while
the insoluble fiber found in flaxseed helps to
slow the release of sugar into the bloodstream
following a meal, preventing rise in blood
glucose levels.
11- Flaxseed is rich source of Magnesium which is
used in the production of prostaglandin E1 which
is a powerful vasodilator. Vasodilator causes the
blood vessels to relax and widen, allowing for
easier blood flow and results in a lower blood
pressure. - Flaxseed is one of the few dietary sources
providing 51 ratio of ?-6 (linoleic acid) ?-3
(alpha linolenic acid) which is considered as the
best ratio in the diet. Â Omega 3 fatty acids
reduce inflammation. Flaxseeds contain 41 fat,
of which 73 are polyunsaturated fatty acids
(PUFA), 18 are monounsaturated fatty acids
(MUFA) and 9 are saturated fatty acids (SFA)
making it a low saturated fat food. - 20g flaxseed powder is effective in lowering
blood glucose,lipid profile and blood pressure.

13Soyabean
14- Role of soy bean in diabetes
- The protein and fiber in soybeans can prevent
high blood sugar levels and help in keeping blood
sugar levels under control. -
- Role of soy bean in heart disease
- Soy is cholesterol-free
- The soy proteins reduce the cholesterol level
- Most of the fats in soy products are
poly-unsaturated - Soy isoflavones prevent atherosclerosis
- Soy contains soluble fibers which reduces the
amount of cholesterol circulating in the blood. -
- Role of soy bean in blood pressure
- Soy protein supplements could help prevent high
blood pressure in people at risk, and lower it in
those with early stage hypertension -
- Consumptiom of 25 gm of soya protein per day may
lower the risk of heart disease and protecting
many cancers. - Â
15Whey Water
- Whey is a nutritious by-product from cheese,
chhana and paneer containing valuable nutrients
like lactose, proteins, minerals and vitamins
etc.,which have indispensable value as human
food. - In India, it is estimated that about 100 million
kg of whey is annually derived as a by product
which may cause substantial loss of about 70,000
tones of nutritious whey solids ( Parekh,2006). - The branched-chain amino acids (BCAAs) present in
whey stimulate muscle protein synthesis. - The proteins of whey belong to protein of highest
biological value because of their amino
acid composition. Biological active peptide
sequences which become effective during
digestion are of importance for secretion of
entero- hormones as well as for immune enhancing
effects.( Barth CA and Behnke U, 1997)
16- The conversion of whey into beverages through
fermentation or without fermentation is one of
the most attractive avenues for the utilization
of whey for human consumption.

17Cauliflower leaf powder
- In India, the consumption of green leafy
vegetables is very low and is much below the RDA.
Therefore, majority of Indians don't meet
sufficient vitamins and minerals present in leafy
vegetables. - At the time of harvest cauliflower produces 60
leaf part and 40 edible curd. - The present practice is to send the cauliflower
to the market along with the leaves as a result
the leaves end up as garbage, which could
otherwise be utilized as a value added product. - Cauliflower leaves which are generally thrown
away as waste are rich source of Iron , protein
and beta- carotene and contribute these nutrients
to the diet. - These are cheap and best source of vitamins and
minerals and can be well incorporated in its
powder form in the beverages.

20Broccoli
- Broccoli is classified in the Italica cultivar
group of the species Brassica oleracea. The
scientific name of broccoli is Brassica oleracea
L. var italica Plank. - Broccoli is known as the Crown Jewel of
Nutrition since it posses all the nutrients
namely vitamins, minerals, secondary metabolites
and fiber proclaiming its exceptional health
benefits. - Leaf and stem parts of broccoli exhibit certain
levels of antioxidant properties. Therefore, a
proper stem or leaf processing or treatment to
develop a new type of product could enhance the
utilization of broccoli.
21Role of Broccoli in Diabetes
- Glucose oxidation is believed to be the main
source of free radicals. Hyperglycemia is also
found to promote lipid peroxidation of low
density lipoprotein (LDL) by a superoxide-dependen
t pathway resulting in the generation of free
radicals. - Active component Isothiocynate(Sulphoraphane)
- Minerals K, Ca, Mg, Cl, P and S and trace
elements such as Fe, Zn, Cu, Mn, and Se. - Antioxidants flavanoids, phenolics and Vitamin C
22Sulphoraphane
- Significant reduction of molecules in the body
called Reactive Oxygen Species (ROS).
Hyperglycaemia can cause levels of ROS to
increase three-fold and such high levels can
damage human cells. The results of the study
showed that Sulforaphane reversed this increase
in ROS by 73 per cent. - Activated a protein in the body called nrf2,
which protects cells and tissues from oxidative
stress by activating protective antioxidant and
detoxifying enzymes. The study showed the
presence of Sulforaphane in human microvascular
cells doubled the activation of nrf2. - It may help counter processes linked to the
development of vascular disease in diabetes. - It produces enzymes that protect blood vessels by
reducing tissue damaging substances triggered by
high blood sugar levels.
23MINERALS AND VITAMINS
- Chromium a micronutrient exhibiting lot of health
benefits is present in broccoli to the level of
12mcg/100gm . -
- Presence of mineral micronutrients such as zinc,
chromium and selenium, in broccoli is lucrative
to be a potential antidiabetic and antiobese
functional food apart from its chemoprotective
and cardioprotective role.
24- Broccoli is a significant source of flavonoids
and phenolics such as caffeic and sinapic acids.
A large number of hydroxycinnamic acid esters of
kaempferol and quercetin glucosides has been
characterized . - The antioxidant activity of phenolic compounds is
due to their ability to scavenge free radicals,
donate hydrogen atoms or electron, or chelate
metal cations . - The structure of phenolic compounds is a key
determinant of their radical scavenging and metal
chelating activity, and this is referred to as
structureactivity relationships (SAR). -
- In the case of phenolic acids, the antioxidant
activity depends on the numbers and positions of
the hydroxyl groups in relation to the carboxyl
functional groupized in broccoli inflorescence.
25- Vitamin C is abundant in broccoli and is used as
a biomarker to identify the nutritional quality
of organic, conventional, and seasonally grown
broccoli. - Cruciferae seeds and ready-to-eat sprouts are a
good source of Vitamin K, B1 and B2. - Vitamin K (phylloquinone) is a fat-soluble
vitamin that functions as a coenzyme and is
involved in blood clotting and bone metabolism,
and broccoli contain gt100 mcg phylloquinone/100 g
vegetable, either raw or cooked. - Apart from these vitamins, broccoli also contains
good quantities of antioxidant vitamins namely
tocopherols and ascorbic acid and carotenoids
(luetin and zeaxanthin)

Functional beverage
- Supplementation f 200 ml of developed functional
beverage by using 5gm of cauliflower leaf powder
,10 gm pearl millet, 20 gm jaggery, 40 gm banana
,126 ml of whey, significantly increased blood
glucose level , serum retinol level and
haemetological profile of the adolescent girls. - It also help to prevent fluid loss and reduce the
fatigue level which in turn bring about full
sport potential.
27- Significant (plt0.01) increase was observed in
heamoglobin (9.42), mean corpuscular volume
(2.08 ), packed cell volume (3.35 ), mean
corpuscular haemoglobin concentration (1.73),
blood glucose level (12.7 ) and serum retinol
level (5.46 ) of the subjects. - The consumption of underutilized food such as
whey water, pearl millet, cauliflower leaf powder
by the adolescent girls should be encouraged to
improve their nutritional status.
28Medicinal Plants
- Use of medicinal plants like aloe vera, bael and
stevia, by the diabetics should be encouraged as
they help to manage the blood glucose level and
lipid profile of the diabetics.
29Aloe vera
- Each leaf is composed of three layers
- An inner clear gel that contains 99 water and
rest is - made of glucomannans, amino acids, lipids,
Phytosterols - vitamins.
- The middle layer of latex which is the bitter
yellow sap and - contains anthraquinones and glycosides.
- The outer thick layer called as rind which has
protective - function.
30CHEMICAL COMPOSITION
31BENEFITS OF ALOE VERA
32- Supplementation of 100mg and 200mg of Aloe vera
L. gel powder along with nutrition counselling
significantly reduced blood glucose levels and
blood pressure along with an improvement in lipid
profile of the non - insulin dependent diabetics. - It is Non- toxic, safe ,cost effective, easy to
consume in capsule form -
33Stevia
34-
- Stevia helps in reduction of blood glucose levels
- Stimulates insulin secretion via a direct action
on pancreatic ß-cells. - Decreases glucagon levels.
- Decreases insulin resistance and increases
insulin utilization. - Has gluconeogenesis slowing down action.
- Acts to increase skeletal muscle glucose
transport system to increase glucose disposal.
35- Sugar provides 4 Kcal per gram. Consumption of
sugar adds extra calories to our diet. These
extra calories lead to weight gain and obesity. - Since stevia is a ZERO CALORIE sweetener. Its
consumption would help to reduce calorie intake
and thus contribute to weight loss. - Stevia upto 75 mg can be used in place of sugar
for commonly used sweet preperation.
36Bael
- Bael leaf, pulp and seed can be used by the
diabetics to improve their nutritional status. - Various products can be made by using bael pulp.
- Farmers should be motivated to grow bael as it
is non-toxic , cost-effective and safe for
diabetics.
