| Introduction The most important
aspect of paediatrics or childhood is growth and
development, as they are the parameters of health
and disease.
Definition
of Vegetarian Foods in Relation to Milk
It should
be emphasized that the milk which is produced by
human and other animals is also one of the most
important items of vegetarian diet even though it
is of animal origin. For example, human milk
produced by the baby's mother is the best and
most suitable food for the baby and from every
angle, it is vegetarian even though it is of
animal (human) origin. God has provided specific
milk for human babies. Its function is not bnly
to provide essential nutrients of specific
composition, so that it is easily digested by
babies and utilized for their rapid growth but
also to provide strong and special defence
against various infections, infestations and
allergens. It also leads to emotional bonding
between the mother and child.
When human
milk is not available, we have to take recourse
to animal milk like that of a cow, a buffalo or a
goat.These animals' milk can be used for
children, particularly infants, but in a modified
manner, because of their relatively poor
digestibility, lack of supply of defensive
substances which a human new born or infant needs
and absence of true emotional bonding between the
mother and the child which occurs when the baby
is breast-fed.
Basic
Vegetarian Foods
Cereals
and Sugar
These are
mainly concerned with growth and tissue repair.
They are particularly important in childhood when
the body is growing rapidly.
Fats
It is
essential to emphasize that the fat cells laid
down in infancy and early childhood are very
difficult to reduce even at a later age. Hence
programmes of prevention of obesity and its
various complications should be started in
childhood by restricting too much fat in the diet
as it is a rich source of calories.
Pulses
The
combination of cereals and pulses makes very good
food as it provides calories for energy, protein
for growth in children and for repair of the
tissues.
Vegetables
Vegetables
are very important items of a child's diet. They
are rich in minerals like iron and some vitamins
particularly vitamin A and C and many other
nutrients mentioned in the earlier chapters.
Fruits
They form
an important constituent of vegetarian diet as
they supply vitamins, minerals and easily
digestible sugars. Ripe bananas, apples, sweet
limes and oranges are commonly used in children.
Vitamins
Some of the
vitamins and the adverse effects of their
deficiency especially in children will be
described here.
Vitamin
A
With
deficiency of vitamin A, children develop night
blindness, dryness of conjunctiva and with severe
deficiency the cornea or transparent part of the
eyes becomes hazy and is ultimately destroyed. It
may be mentioned that as many as 40,000 children
become blind in India every year and 40,000 are
at the risk of blindness. The small expenditure
of rupees two per child per year on vitamin A
given by mouth twice a year for the first 5 years
can prevent blindness and its socio-economic
miseries (Fig. 6). It is almost a
tragedy that the society, community and various
governmental and non governmental agencies cannot
play their role adequately in tackling this
problem. The poor child's Vitamin A requirements
can be met with cheaply through green leafy
vegetables like drumstick leaves.
Vitamin
B1 or Thiamine
It is
essential for the proper functioning of the
various enzymes and proper functioning of the
nerves. With deficiency of vitamin B1 or
thiamine, the child develops swelling of the legs
and face, fatiguability and at times marked
weakness of the lower limbs. In severe cases they
may be unable to walk because of paralysis of the
lower limbs which initially involves the feet and
later spreads to both the lower limbs.
Fortunately this is rare in our country, because
in most of our traditional cooking unpolished
rice is consumed. It is also desirable to use
minimum water to cook the rice. It is not good to
throw away the supernatant water floating over
the cooked rice as it contains the essential
nutrient viz. vitamin B1 or thiamine.
Nicotinic
Acid
This is one
of the B2 vitamins which is necessary to maintain
the health of the skin, intestine and mental
functions. Deficiency of nicotinic acid produces
dermatitis (skin changes), diarrhoea and has
adverse effect on mental functions.
Riboflavin
(vitamin B2)
It is
essential for the normal condition and
functioning of the mucocutaneous junctions like
those of the army of the mouth, anal region and
also the mucous membrane of the tongue,
vulvovaginal junction and eyes. With involvement
of the eyes, the child gets lacrimation
(excessive watering), itching and burning
sensation due to conjunctival irritation and
vascularisation (growth of blood vessels) of the
cornea.
Vitamin
B6 or Pyridoxine
This is one
of the important vitamins necessary for the
proper functioning of the nervous system
including brain and nerves. It is also necessary
for the formation of blood. With deficiency of
vitamin B6, the child may get anaemia, similar to
the type caused by iron deficiency. With its
deficiency the child may get involvement of the
nerves with tingling, numbness, weakness of the
muscles, particularly of lower limbs. It is also
necessary, along with vitamin B12, for the
formation of myelin or white matter of the nerves
and the brain. Pyridoxine deficiency may, rarely,
produce convulsions in new born babies and
infants.
Folic
Acid
Folic acid
is the vitamin necessary for the formation of
blood. With deficiency of folic acid the child
develops megaloblastic anaemia.
Vitamin
C or Ascorbic Acid
This is a
very important vitamin for the proper maintenance
of the functions of the lining of blood vessels,
collagen tissue, proper formation of bones. It
also helps in fighting against infection and to
stand various stresses and strains as it helps
the adrenal cortex (one of the endocrine glands)
to function well. Without vitamin C the child
will develop weakness, anaemia, poor appetite,
frequent infections, and if the deficiency is
severe, the child develops bleeding from the
gums,bones and various tissues. However, the most
important effect is on the bones in which because
of bleeding under the periosteum (the outer
covering of long bones) and damage to the ends of
the bones (viz.metaphyses and epiphyses) the
child gets severe pain and develops what is known
as pseudoparalysis i.e. limbs, though appear
paralysed, are not actually paralysed but appear
so because of severe paun.
Vitamin
D
This is one
of the important vitamins which is essential for
the growth, proper formation and strength of the
bones and muscles. It also enhances immunity.
Vitamin D is formed in the body by exposure of
the skin to morning or evening sunlight and also
from the food. The tradition of oil massage to
the baby and exposing him / her to the
ultraviolet rays of the sun mainly available in
the early morning and evening, is common in our
country and is useful. Lack of exposure to sun
and overclothing can lead to signs of deficiency
of vitamin D. With its deficiency, the child will
develop softening. The softening of the bones
leads to bending of the bones, deformities and in
severe cases fracture of the bones. It may be
emphasized that even though milk is an excellent
food it is deficient in vitamin D and hence
vitamin D supplements must be given to babies on
mother's rnilk or top milk feeds. We see a high
incidence of rickets in breast-fed babies who
grow very rapidly, if deficiency of vitamin D is
not corrected by adding vitamin D in the diet or
exposing the child to ultraviolet rays of the
sun. With vitamin D deficiency the infant may get
low levels of calcium in the blood
(hypocalcaemia) which is a common cause of
convulsions and spasms in infancy and early
childhood.
Minerals
It is
desirable to mention a few of the important
minerals here. The iron is derived from the
vegetables particularly green leafy vegetables.
If not taken in adequate amount it will lead to
what is known as iron deficiency anaemia. It is
an extremely common condition in children and as
many as 70-80% of the children have mild,
moderate or severe anaemia. Iron deficiency
occurs in children of poor and middle
socio-economic groups not only because of iron
deficiency in the diet but also due to parasitic
infestations like hookworms. Often the frequent
infections in these children interfere in the
utilisation of iron to form blood. It may be
mentioned that in severe anaemia, particularly
due to iron deficiency, when haemoglobin is less
than 50 - 60% or 8 gms% or less (normal being 12
to 14 gms%), the child develops immune
incompetence or lack of resistance to fight
infections as the anaemia affects the T
lymphocytes which are vital in the maintenance of
T cell immunity.
Copper
Though this
is essential in the normal diet, it is adequately
met with when iron containing foods are taken, as
they usually go together.
Calcium
and Phosphorus
These are
the main constituents of the bones and are also
found in other tissuesfor example muscles.
They are important fo formation and giving
strength to the bones. Calcium is also im portant
in the maintenance of proper cardiac function.
Deficiency of calcium can lead to poor formation
of bones. However, inspite of adequate amounts of
calcium, if vitamin D is not supplied, the child
can get rickets. One of the most important
functions of calcium is to maintain the normal
functioning of the nervous system. This is
particularly important in children but much more
so in infancy which is a period of rapid growth,
where associated vitamin D deficiency leads to
severe calcium deficiency and the child may get
convulsions or spasms of the limbs, a condition
which is known as tetany. However, a diet which
is adequate in amount and contains milk and milk
products (butter, ghee,cream etc.), pulses and
vegetables will supply adequate calcium. Symptoms
of calcium deficiency are usually secondary to
deficiency of Vitamin D.
Iodine
Iodine is
one of the most important minerals in the
vegetarian diets. Moreover, iodine can be
supplied in iodised salt. Iodine deficiency is a
major health problem in India. About 120 million
people in India live in the known goitre endemic
regions and 4.0 million people are afflicted with
goitre. For example, Delhi has been identified to
be an endemic goitre area. The development of new
goitrogenic areas are related to iodine
deficiency and presence of goitrogenic foods
which could inhibit the synthesis of the thyroid
hormone. Thiocyanates present in many foods like
cabbage,turnip, various staple foods like maize
and millets and in milk in which it is added as a
preservative, are the most important goitrogenic
agents. When there is adequate iodine in the
diet, the effect of moderate levels of
thiocyanates on inhibition of thyroid hormone
synthesis will be prevented.
Taken in
large amounts thiocyanates can cross the
placental barrier and high concentration in
foetal plasma results in severe congenital
hypothyroidism. However, as they are not
concentrated in the mother's milk, breast-fed
infants are protected.
With
addition of thiocyanates as a preservative and
its subsequent consumption by pre-school and
school children with marginal iodine in the diet
and consumption of other goitrogenic foods,
goitre and impairment of physical growth and
mental development may result.'
Micronutrients
These are
very small amount of nutrients required for vital
metabolic function.
Magnesium
Magnesium
is important in metabolic functions. Most of the
magnesium is in the bones along with phosphate.
Magnesium is bound to proteins. In the cells it
is concentrated in the mitochondria and is
essential for many enzyme systems for transfer of
energy. Cereals and vegetables are good sources
of magnesium. Normally there is adequate
magnesium in the vegetarian foods and there is
adequate storage in the body. However, in
children with chronic diarrhoea, and in severe
malnutrition, particularly kwashiorkor, there may
be well marked deficiency which produces
twitching, tremors and convulsions.
Zinc
It is
necessary for protein and carbohydrate
metabolism. The vegetarian foods, particularly
unmilled cereals and legumes, are rich in zinc.
Prolonged deficiency of zinc in infants and
children with severe chronic diarrhoea may lead
to stunted growth. Deficiency of zinc may also
produce excessive crying in infants, lack of
concentration in older children and skin rash.
However, under usual situations deficiency of
zinc is rare.
Importance
of Adequate and Balanced Diet
In a normal
healthy child carbohydrate supplies 45 to 50%,
fats 25 to 35 % and proteins 10 to 15% of the
total calories. A child of one year needs about
1000 to 1100 calories which is met with by giving
him a diet which supplies 600 to 650 calories
from carbohydrate, 40 to 50 calories from
proteins and 300 to 350 calories from fats. Apart
from the supply of these nutrients of
carbohydrates, fats and proteins other nutrients
like vitamins and minerals are essential as
mentioned earlier.
Undernutrition-Mild,
Moderate and Severe (Marasmus)
If a child
gets lesser calories than the recommended intake,
he develops undernutrition and in severe cases
marasmus i.e.loss of subcutaneous fat all over
the body, marked wasting of the muscles and the
child appears thin and wasted having mainly skin
and bones. (Fig. 3) If these children
have inadequate intake of vitamin A and iron and
at the same time, they get frequent infections
and have intestinal parasites like worms, they
get signs of vitamin A and iron deficiency. This
is a very common condition seen in children of
poor socioeconomic groups.
Kwashiorkor:
(Fig. 5 plate)
This is a
condition in which the child fails to grow, gets
swelling or oedema of the legs, puffiness of the
face or moon facies. Hair becomes brittle and
less dark. The child gets severe weakness of
muscles and the liver becomes fatty with adverse
effects on its functions. However, the most
important effect is on its brain and mental
development. Such children may remain physically
stunted and mentally subnormal inspite of various
methods of developmental intervention and
rehabilitation. We can prevent these conditions
by the following advice: (1) By encouraging
breast feeding; (2) By increasing yield of
mother's milk by proper advice on her diet which
is suitable and cheap, and most important, by
education of the mother and health personnel on
the importance of breast feeding; (3) By early
supplementary feeding at 4 to 6 months of age
with mixtures of cereals and pulses, i.e.rice, or
wheat roti and dal and addition of mashed
vegetables and fruits like bananas at 5 to 6
months of age. However, breast milk is the most
suitable milk for the baby as, over and above its
nutrient value, it has protective value against
infection. Fig. 3 A and B shows the defences
in a healthy child and adverse effects of severe
malnutrition on immune defences.
Intrauterine
Malnutrition and Foetal Growth Retardation
In one of
our other studies carried out on malnourished
mothers of low socioeconomic groups it was found
that the low birth weight babies had many
disadvantages. Because of the intrauterine
malnutrition and foetal growth retardation these
babies particularly if they were not
nutritionally rehabilitated, morbidity and
mortality was high and some of them developed
progressive undernutrition because of failure of
supplementary feeding at 4 to 6 months of age.
Studying the brain weights of these babies of
different nutritional groups it was found that
the brain weights were lower in the newborns and
infants with lower intrauterine weights and
growth. Because of the intrauterine malnutrition
these babies had immune incompetence, had very
frequent infections because of the ecological
condition and way of life. The follow up of these
children who had severe malnutrition in infancy
and early childhood over a period of 5 to 10
years revealed that their intelligence quotient
or the mental development was poorer compared to
the healthy controls. These results indicate the
importance of diet of the pregnant mothers. To
have a healthy baby from the point of view of
physical growth and mental development adequate
supply of breast milk and supplementary vegetable
foods, initially double mix (rice and dal or
khichadi) and later triple mix (khichadi and
mashed vegetables and fruits) are necessary (Fig. 1 and 2 and coloured plate Fig. 1 and Fig 2)
Lactation
Mother's
diet during lactation should be around 3000
calories of which milk and milk products should
supply nearly 600 to 900 calories and protein 24
to 40 gms per day. The remaining diet should
consist of usual family diet containing cereals,
pulses, vegetables, fruits etc. It is not
necessary that the mother should have expensive
or costly fruits as one or two ripe bananas a day
will provide 100 to 150 calories along with iron
and calcium. The diet of the mother throughout
the lactation period should be adequate enough
and should contain around 3000 calories from the
diet items mentioned above, because a well
nourished mother will be able to provide a higher
yield of breast milk per day and over a duration
of 6 to 9 months or more. Apart from the diet the
most important aspect of good production of human
milk is the attitude of the mother to breast feed
the baby. The mothers of lower socio-economic
groups are able to supply the breast milk easily
as they know that the breast milk is the only
food for the babies. They have seen their mother,
aunts and other relatives feeding their babies on
the breasts as they have been brought up either
in a joint family or extended family systems. The
only advice these mothers need in some parts of
our country is that the first fluid secretions of
the breast i.e. colostrum is the most important
nutrient as it not only gives concentrated
calories but also supplies large amount of the
antiinfective substances. It is essential to
emphasize that the babies' mouth, stomach and
intestine should have the first contact only with
colostrum which will supply the various
anti-infective factors to the baby. Not only
colostrum and human milk will strengthen the
local immunity in the gut but it will prevent the
entry of any allergens which might do damage to
the baby locally in the gut or systemically to
other organs. Table 1 gives the com parable
advantages of the chemical composition of the
human milk for its digestibility and
utilisability compared to cow's milk. Human milk
contains required amount of proteins for the baby
10.6 gm. per lt. (1.06G%) as opposed to 28 to 36
in cow's milk per litre (2.08 to 3.6 gms%) which
is meant for the calf and not for human babies.
Moreover, the proteins of the mother's milk are
quite different in quantity and quality. Fat of
the human milk is a special one containing
essential fatty acids which are also rich in
calories for the fast growing brain of the baby.
Milk sugar or lactose is much higher in human
milk. Human milk, also supplies digestive
substances for the digestion of fat. It is a
dynamic secretion supplying milk of proper
composition. For example, if the baby is pre-term
or born at 7 months of pregnancy the composition
of mother's milk is changed by Nature (there is
no scientific explanation for this change) to
provide higher content of protein. Mother's milk
also contains hormones and hormone-like
substances which promote growth and many
substances like the amino-acid taurine, which is
a growth modulator. Table 2 provides various
constituents of human mills which are responsible
for the anti-infective property of human milk.
With these anti-infective substances in human
rnilk infections in the breastfed babies are
rarely serious or lifethreatening. Human milk
contains a large number of living cells which not
only synthetize various bio-chemical substances
but also provides antibodies especially secretory
IgA. Nature has given a remarkable enteromammary
immune system in which the T and B lymphocytes
and other cells from the mother's gut get
stimulated by any infection in the child or the
mother, and these activated cells from the
lymphatic tissues in the gut of the mother
migrate to the blood, and later transferred to
her mammary glands (breasts). Ultimately they are
passed into the baby's gastrointestinal tract
through the breast milk to protect against
various infections in the baby. However, the most
important part of human milk is its economic
consideration. If the mothers in India decide not
to breastfeed their baby we will never have
enough animals to provide adequate milk for our
babies. Breast feeding is also one of the most
important ways of family planning; mothers who
breastfeed their babies have lactation
amenorrhoea (i.e. absence of menstruation) which
may last for 6 to 12 months. This makes
breast-feeding the baby as one of the most
important strategies for family planning
particularly in our country.However, other family
planning devices like copper-T should be
introduced in the uterus desirably by about 6
Months of the lactation period so as to prevent
second pregnancy. The interval between the two
pregnancies should be at least 3 to31/2 years.

particularly life-threatening, in breastfed
infants.
Damage
Done to the Lactation (Breast Feeding) by Medical
and Health Personnel:
While rural mothers are able to breast feed
babies almost 95 to 100%, lactation failure or
inability to breast feed the baby is common in
urban areas. In metropolitan cities like Bombay
this is mainly because of the hospital delivery
where adequate attention is not given by the
medical personnel and nurses to emphasize the
importance of breast feeding. Many of them
actually discourage breast feeding instead of
encouraging it, which is almost criminal on the
part of the health personnel. The babies should
be put to the breasts within 4 hours of birth.
The baby should be kept with the mother and not
be taken out and kept in the nursery. The baby
and the mother being together, the mother can
feed the baby on self demand schedule during the
day and the night. Bottle feeding is the biggest
danger, as giving the bottle to the baby reduces
the mother's milk and leads to lactation failure.
Government of India has recommended that bottles
should not be used for feeding babies. However,
there is no legal provision to prevent the use of
the bottle. The medical and health personnel are
mainly responsible for the causation of lactation
failure in urban mothers. The urban mothers need
supportive care from the very beginning and
should be educated and motivated to breast feed
the babies. It is now well established that
breast cancer is 5 times less common in mothers
who are able to breast-feed their babies.

Infant
Milk Feeds
It may be
emphasized that there is no breast milk
substitute, as human milk is live dynamic
secretion from the mammary glands of the mother
which provides all the necessary nutritional
constituents to the baby apart from the
substances for prevention of infection.
All the
infant milk foods are now modified to supply
lower proteins of 1.2 to 1.6 gm% after realising
that high protein content of 3 to 3.5 gm% was
harmful particularly to neonates and infants.
However, inspite of various modification to
simulate the breast milk composition they cannot
have the advantages of mother's milk. These
infant milk foods have an adverse effect on
breast feeding, since if the baby is given infant
milk foods, the breast milk supply declines.
Moreover, as the infant milk foods are usually
given by a bottle they further lead to lactation
failure. Hence the Government of India has
recommended that infant milk powders should not
be used.
Disadvantages
and Dangers of Bottle Feeding
Lactation
Failure or Failure of Breast Feeding
It should
be emphasized that bottle feeding should be
strongly discouraged as by a large number of
studies, it has been well established that bottle
feeding leads to the child's refusal to suck the
breast with the result that the mother's milk
supply declines and there is a failure on the
part of the mother to continue the breast
feeding. Thus the most important advantages of
breastfeeding mentioned earlier are lost. There
is a vicious circle of bottle feeding leading to
reduction in breast milk supply because the baby
refuses to suck the breast and will prefer to
take the bottle feeding more and more. The
ultimate result is that the child gets addicted
to the bottle and develops the bottle addiction
syndrome which was described by us in 1961. It
tnay be pointed out that the child may drink
water from a cup but refuses to take milk except
by a bottle.
There are
many adverse effect of bottle feeding apart from
its important cause of lactation failure.
In
comparatively well-to-do families adequate milk
is available for the child so that he may
continue to take 1-2 litres of milk usually with
the addition of 2 teaspoonful of sugar. These
children develop the condition of protein
overload syndrome (Figs 4 and 5) which was first
described by us in 1964. The younger the child,
the more adverse are the effects of protein
overloading. These children are under-nourished
and often their weight is around 6 kg at 10 to 12
months of age (as opposed to expected 9 to 10 kg)
inspite of an intake of a large quantity of milk.
It must be emphasized that human milk contains
0.9 to 1 gm% of protein, and this protein has
highest biological value, meaning thereby that it
is most digestible and is utilised fully. On the
other hand the child fed on buffalo's or cow's
milk with an intake of 1 to 1 1/2 litre of milk
each day, consumes almost 40 gms to 60 gms of
animal proteins. The infant weighing around 6 to
7 kg takes 7 to 8 gms of protein per kg body
weight per day instead of normal requirement of
1.8 gm per kg per day. This particular condition
results in a characteristic symptoms complex in
the child, which we have described as protein
overload syndrome. The child has excessive
appetite, cries a lot, gets intestinal colic,
wants milk all the time, gets abdominal
distension, is constipated and gets large or
bulky, hard or formed, foul smelling stools and
passes large amount of foul smelling urine. The
child also gets well marked enlargement of the
liver because of the excessive load of fat and
proteins on the liver. High protein leads to
adverse effects on the body metabolism with the
result that the child gets well marked
tachycardia or a very fast heart rate and very
rapid and laboured breathing. At times there is
enlargement of the heart which is probably caused
by retention of sodium in the body as the cow's
or buffalo milk contains 3 to 4 time more sodium
chloride than in mother's milk. There are also
other causes of tachycardia and cardiac
enlargement which are probably related to
endocrine dysfunction. However, the most
important effects of the diet containing high
proteins are loss of weight and failure to grow
inspite of the child's intake of high calories
from the large quantity of irnbalanced food. This
can be worsened by the addition of non-vegetarian
foods like eggs, chicken, fish etc. as they add a
further load of proteins in the diet. The diet is
very much imbalanced as it contains high
proteins, high fat and usually low carbohydrates
particularly when the sugar is not added
adequately to the milk or the child refuses to
take other carbohydrate foods like rice and wheat
cereals or other foods. There is another adverse
effect of high protein diet which is particularly
well marked on younger infants and neonates. This
is seen in low birth weight babies who do not
receive mother's milk but receive cow's or
buffalo's milk or full strength infant milk
formula which contains 3 to 3 1/2 gms of protein
per 100 ml of the formula. These infants
particularly neonates or low birth weight babies
with large intake of proteins in the diet get
high blood urea, increase in blood ammonia
levels, acidosis and disturbance in the
electrolyte balance. High ammonia levels in the
blood are harmful as they can produce damage to
the brain particularly of neonates, low birth
weight babies and young infants. We have
described this condition as Nutritional
Hyperammonaemia. Some of the American workers
have followed the low birth weight babies given
high protein diet in the neonatal period and
infancy and found that progress of these children
at school even at the age of 7 years was found to
be slower. Such an adverse effect on the
development of infants has also been reported by
us.
Other
Effects of Too Much Intake of Animal Milk Which
Leads to Imbalanced Diet
There are
other adverse effects of imbalanced diet which
results from high intake of protein from animal
milk and the non-vegetarian diet like eggs, meat,
fish, chicken which may be given to the child of
1 to 1 1/2 years. This results in severe
constipation, large foul-smelling stools, foul
smell in the breath and these children may get
severe attack of intestinal colic from large
curds formed from high protein milk of buffalo or
cow. The imbalanced diet also causes moderate to
severe anaemia in the child due to deficiency of
iron. These children have haemoglobin values 3 to
8 gms% i.e. 25 to 60% of the normal values.
Tetany:
Tetany is a condition in which the child gets
fits due to low blood levels of calcium. Infants
with high intake of animal milk get a very large
amount of phosphorus from it and often get what
has been described as hyperphosphataemic
hypocalcaemic convulsions. The condition is
further aggravated if the child has associated
rickets because the animal milks are poor in
vitamin D.
Effect
of Bottle Addiction in Children of Poor
Socio-economic Group:
Fortunately
poor mothers usually feed their babies on the
breasts and hence the infants are protected
against infection and imbalanced diet which is
likely to happen in non-breast fed babies.
However, when the mother from a poor family
cannot breast feed the baby it is almost a
catastrophe. These mothers often imitate the rich
mothers in whose house they may be working.
However, because of the poverty and unsanitary
and unhygienic conditions the bottle feeding has
tragic consequences. As they cannot afford good
quality of milk or if they are using infant milk
foods, often the milk is overdiluted because of
ignorance and poverty. Usual dilution of an
infant milk food is one measure or one
teaspoonful to 30 ml of water and normally the
child is.given 5 to 6 measures of powder with
150-180 ml of water. Often in 200 to 240 ml of
water 1 l/2 to 2 teaspoonful of powder is added.
This results in the child consuming large amount
of water from the milk but relatively much lower
intake of total calories which are required for
growth and development. It is worthwhile to tell
a true story of a grandchild of a doctor, who was
kept on powder milk formula. As the child had
diarrhoea earlier, he was given 1 to 2
teaspoonful of powder with 240 ml of water. The
child was consuming a large quantity of the
formula which contained l/4th the required amount
of milk powder and too much of water with the
result that this infant whose weight was 5 1/2 kg
or 11 1/2 pounds at 3 months of age actually
weighed 4 1/2 kg or 10 lbs at 11 months of age.
As this was a doctor's grandchild, the living
conditions were good. However, the child
developed severe malnutrition as he got only 240
calories in a day instead of getting 800 to 1000
calories from a balanced milk formula containing
lower proteins. What usually happens in poor
socio-economic groups is that apart from the
unhygienic surroundings, lack of proper drinking
water, lack of proper washing of the bottle,
which are often medicine bottles used for feeding
with dirty teats, these infants get a diluted
unhygienic milk contaminated with bacteria with
which they usually get diarrhoea and they become
malnourished. This condition has been described
as diarrhoea-marasmus syndrome in bottle fed
babies in poor socio-economic groups. Unless
early intervention takes place and diet is
corrected and the bottle discontinued these
children get severely marasmic and die of
diarrhoea, pneumonia and at times of tuberculosis
(Fig. 4 coloured plate).
Carbohydrate
Malnutrition
This is
another condition which we described as
carbohydrate malnutrition The condition was due
to the lack of addition of carbohydrates like
adequate amount of sugar, in the milk or other
carbohydrates, like rice or other solid
carbohydrate diet. The infants have poor intake
of carbohydrate foods which provides 20-25% of
total calories these children have a higher
intake of calories from proteins and fats. They
develop severe malnutrition because of deficiency
of carbohydrate which start the process of
imbalanced diet containing high proteins and fats
but lower carbohydrates (Fig. 6). The condition
becomes worse in older infants or toddlers with
addition of non-vegetarian diet like eggs, meat,
fish or chicken which provided extra calories
from proteins but not carbohydrates, which are
normally supplied in vegetarian food by sugar,
jaggery, rice, wheat, vegetables like potatoes,
fruits like bananas and to some extent by pulses.
These are the various syndromes which can occur
on infant because of imbalanced diet and which
cannot occur in breastfed babies (Fig. 7).
Health
and Growth of Preschool Children and Adolescents
with Different Calorie Intake from the Diet
We have
discussed the health and its impact on growth in
infancy and early childhood.
Preschool
Child Population
Preschool
child population or the children from 1 to 6
years constitute this group. Preschoolers form 17
to 18% of the population in the community though
in recent years with family planning it
constitutes about 15% of the community.
Health,
Growth and Diet During Preschool Period
(Preschoolers):
Health, growth and nutrition during the preschool
period are so much interrelated that they could
be called synonyms. There are various dietary and
other factors which are responsible for
undernutrition and growth failure during
pre-school period. However, we are concerned here
with the dietary aspects. Tables 6,7 show the
calorie intake of a preschool child. It can be
seen that the mean calorie intake is about
two-third of the recommended calorie allowances,
however, the mean protein intake is fortunately
not significantly less. The reduced calorie
intake is mainly because of poverty but often
also due to ignorance. It is essential that the
preschooler should get 1200 to 1500 calories in a
day. It can be met with from half a litre of milk
with sugar and wheat or rice cereal, pulses or
dad vegetables and fruits like bananas. It is
essential that food should not be bulky. The
children should have 4 meals a day so that the
bulk at one time is reduced and the calorie
intake meets with the demand of protein,
carbohydrates, minerals and vitamins. Moreover,
it is undesirable to eat 'too much' of snacks
like chocolates, biscuits, groundnut, or gram dal
preparation in-between the main four meals as
excess of these snacks will reduce the appetite
for a balanced diet. Table 8 gives simple low
cost diet for young children from 2 to 6 years of
age. As per the prices in 1986 compared to those
in 1976 the cost is 3 to 4 times higher which
means that diet of the child of around 2 years
will cost about Rs. 40 to 50 a month, 3 to 6
years about Rs. 60 to 70 per month. Such a diet
will provide adequate amount of calories,
proteins, carbohydrates, fats and essential
nutrients like vitamins and minerals. The
recommended vegetarian diet which is economical
can be used for the preschoolers as this is a
very important period of excessive physical and
mental activity and social interaction. In our
study (Fig. 8) of preschool
children from different socio-economic groups, it
was found that the preschoolers from poor socio
economic groups were lagging behind in weight by
a period of 1 to 5 years. This meant that a child
of 3 years from lower socioeconomic groups
weighed around 10 kg which was the weight of the
child of 1 year in the upper income groups, or a
child of 11 years from the poor socio-economic
groups weighed 22 to 25 kgs which was the weight
of child of 6 to 7 years of age in the upper
socio-economic group. The main cause of
differences between the lower and upper income
groups was reduced food intake. The inadequate
amount of food intake was due to not only
financial constraints but also to ignorance. If
the balanced vegetarian diet mentioned in the
Table is given to these children in adequate
amounts their weight (nutrition) and height
(growth) will both improve significantly.
Moreover, the vegetarian diet mentioned in the
Table is 2 to 3 times cheaper than the
non-vegetarian foods which the vast majority of
the population cannot afford.

Health
and Growth of School Cbildren and Adolescents
The health
and growth are adversely affected by inadequate
intake of food inspite of the fact that adequate
calories and nutrients can be given from the
simple vegetarian diet mentioned in the Table
with the only change being that the calorie
intake should be increased from 1600 to 2000 for
school children and 2200 to 3000 in adolescents.
The calories should be from various balanced
constituents of the food. The graph shows the
growth curves of adolescent children in poor
rural population compared to the one prepared by
Indian Council of Medical Research after studying
5 million children of all age groups from all
over the country and are compared to the growth
of adolescents at Harvard (USA). It may be
emphasized that mainly by increasing calorie
intake from the various nutrients, the growth
curves will certainly improve.
The cost of
diet in the school child will be about Rs. 80 per
month while in the adolescent it will be about
Rs100 to 120 per month. Moreover, it is a
practical diet as the vegetarian diet is
affordable by a large section of the population
and should be advised so as to improve health and
growth of these children. At the same time with
improved health and growth there will be a
reduction of disease, better development of
resistance, better intellectual school
performance, as well as improvement in sport
activities. This is of importance for the nation
as these are the children who will be entering
into the 21st century as the builders of the
nation, as the future citizens of the country.
Adolescent
Rickets (Fig. 7A & Fig. 7B)
A passing
mention may be made on another condition which is
preventable by a proper diet and or by getting
adequate ultraviolet rays of the sun in the early
morning or in the evening which converts
provitamin D in the skin to active vitamin D.
