COMMON
DIETARY MYTHS
Sooji or Semolina is a healthy and nutritious whole
grain and is better than refined maida
In
reality, Sooji or semolina or Rava is the granular form of maida-
a polished grain; their nutritional contents being the same.
A
whole grain is made up of four main parts-
- The
Husk, which is inedible
- The
outer tough Bran or the fiber rich part
- The
Endosperm, the starch rich part which basically provides complex
carbohydrates and energy.
- The
Germ, nutrient rich part wherein all the goodness of the grain
is concentrated. The germ is really the embryo of the seed
situated at the base of the grain rich in proteins, fat and
the richest source of vitamin E – an antioxidant vitamin and
vitamin B complex, Iron, magnesium and chromium.
During
milling, the fiber rich bran layer is removed but the germ which
is also attached to the bran gets ripped off. Thereby, the grain
looses its fiber and nutrition leaving mainly the endosperm-
the starch rich part without the goodness of the grain. The
further grinding of this yields maida however, the grinding
of the whole grain yields atta. The granular form of the endosperm
is called Sooji (Semolina/Rava). This is the basic difference
between brown rice and polished rice.
Bananas and
Apples are rich in Iron because they turn brown
Fruits
also form an essential part of one’s diet as 5-6 servings of
fruits daily provide adequate amounts of protective nutrients
and disease fighting substances in the color of their skins
called phytochemicals. Fruits are rich in vitamin C and like
vegetables contain cellulose which is indigestible and adds
bulk to the stools; and are thus mild natural laxatives .Most
fruits also form a good source for beta carotene or vitamin
A- an antioxidant.
Iron
is an essential element for the formation of hemoglobin and
plays an important role in the transport of oxygen to the cells.
Cereals, millets, pulses, green leafy vegetables form the rich
sources for iron but one of the greatest myths which people
have is that apples and bananas are the fruits which are also
good sources of iron as they turn brown. The facts pertaining
to these fruits are as follows-
“An
apple a Day keeps the Doctor Away” is certainly no exaggeration
for the apple is indeed a storehouse of vitamins, minerals and
many other vital nutrients. Apples are rich in vitamin C and
vitamin E and cholesterol lowering fiber.
Bananas
are a fruit which requires special mention as they contain large
amounts of carbohydrates and are a useful source of energy.
Even
though apples and bananas are a store for different protective
nutrients but the content of iron in apples (0.7 mg/100gm) and
bananas (0.4 mg /100gms) is negligible when compared to some of the richest sources for iron
like dry lotus stem
(60.6 mg iron /100gms), rice flakes (20 mg iron /100g), radish
leaves (18.0 mg iron/100gm), parsley (17.9 mg iron /100gms )
or Bajra (8.0 mg iron /100gms).Even fruits like dates (7.3 mg/100gms),
water melon (7.9 mg/100gms) and dry fruits like raisins (7.7
mg/100gms) are good sources of iron.
Milk and Dairy products are unnecessary in the diet
after 2 years of age
IMPORTANCE
OF MILK
Unlike
Western populations, the vast majority of Indians are Lacto-Vegetarians,
that is, they drink milk and eat foods of plant origin. Since
majority of the Indians do not have eggs and flesh foods as
their staple diet, dairy products are their chief source of
first class proteins. Milk and milk products like curd, butter,
desi ghee, mithais, paneer, form the major source of animal
fats in the Indian diets.
The
first class proteins provided by milk and milk products contain
all the essential amino acids, the building blocks for normal
growth and development. Some fatty acids present in the milk
also contribute to normal growth. In Indian society, therefore
milk and milk products lay vital role in children’s growth and
development.
Besides
proteins, dairy products also provide energy, vitamin A, D,
riboflavin and minerals such as calcium, magnesium, phosphorus
and potassium. Milk and Milk products help build healthy bones
in children.
HARMFUL
EFFECTS OF MILK DEPRIVATION DURING GROWING YEARS
Children
and teenagers need energy to grow and develop. Detrimental effects
of milk deprivation are evident in underprivileged sections
of the society, where children have a high prevalence of PEM
(Protein Energy Malnutrition) and blindness due to vitamin A
deficiency. Had their consumption of milk and milk products
been adequate, these problems could not have assumed such proportions.
Whole
milk is an energy packed food due to its fat content. Consuming
1 gm of fat provides 9 Kcals. of energy, compared to merely
4 Kcals. for an equivalent amount of sugar. Therefore, whole
milk and milk products are appropriate for children with limited
access to food to prevent energy malnutrition.
Encouraging
milk consumption is a part of the recommended strategy for prevention
of PEM and blindness due to vitamin A deficiency in preschool
children in our country.
As
children reach their teens, they reduce milk intake, this is
considered normal by the parents, who believe that milk is not
so necessary for children who have reached puberty. Adolescents
of well to do families tend to stop milk intake altogether to
keep
‘Fit
and beautiful”. Due o irrational fear of weight gain, teenagers
often substitute
- Soft
drinks or other carbonated beverages for milk.
- In
their constant quest for shape, girls may opt for energy free,
nutritionally empty beverages.
In this age of fitness mania, it is often forgotten that the consequences
of being underweight in the growing age are harmful while mild
overweight may be healthier. The most damaging consequence of
insufficient milk intake during childhood and adolescence is
dwarfism due to insufficient energy and calcium intake. Other
potential adverse consequences of abhorring milk and milk products
include:
- An
Involuntary increase in sugar intake in form of candy, and
sweetened beverages to compensate for inadequate energy intake.
- Spells
of Binge Eating.
- Preference
of Snacks and junk foods available in restaurants and fast
food counters.
- Insufficient
intake of vitamins and minerals.
- Delayed
sexual maturation.
Too
much of negative focus on dairy foods is counterproductive and
may be deleterious for the health of growing children adolescents.
However, when fat restriction is advisable in childhood or adolescence
due to overweight or some other medical problems, there are
better choices than reducing milk intake-
- Consuming
low fat milk and dairy products
- Reducing
snacks cooked in hydrogenated oils, vanaspati and fried foods.
Hence,
it is undisputed that no single plant source of protein can
match the protein quality of milk and diet of children is incomplete
without the integration of milk and milk products particularly
among vegetarians. However, after 3-4 years of age low fat milk
and milk products are recommended.
Table salt is more harmful than cooked salt
If
you thought that that adding salt to food on the table is more
harmful than cooked salt- think again! Salt added at any stage
of cooking will continue to provide the same sodium content.
Infact, it is the total intake of salt (cooked/ table) which
is of importance. While it is true that salt is needed to make
food palatable and for the healthy functioning of the body,
it is also important to know that most of us today eat far more
salt or sodium than our bodies need. Excess salt/ sodium can
be harmful for most people. It can lead to problems of bloating,
water retention, high blood pressure and even frank oedema.
Salt restriction is needed in the management of several medical
conditions including high blood pressure, kidney disease and
heart failure. Some studies have shown that excess sodium in
the diet can lead to bone loss leading to osteoporosis. It has
also been found that the incidence of stomach cancer is high
in populations eating high salt like the Japanese. Besides cooking
and table salt there are many hidden sources of sodium in our
diets. These include Achaars, Chutneys, Pickles, processed foods
like sausages, bacon, bakery items and salted snack foods. Some
foods are naturally high in sodium particulaly green leafy vegetables.
Learn to enjoy the natural taste of salt rather than smothering
it with salt and spices.
Spinach is a good source of iron and eating lots of
it helps in preventing anemia.
Iron
is an important mineral for formation of hemoglobin, the red
pigment in blood which helps transport oxygen to every cell
of the body. A low level of hemoglobin that is below 12mg/dl
can lead to anemia. Symptoms of anemia include fatigue, breathlessness,
hair loss and palor.
Iron
content of spinach is not as high as it is imagined to be as
100g of spinach contains a mere 1.14 mg iron whereas cauliflower
greens contain 40 mg/100 gms, amaranth (Chaulai) contains 20
mg/ 100g, radish leaves 18 mg; mustard greens (Sarson saag)
has 16.3 mg/ 100g, beetroot greens have 16.2 mg/100g and bathua
contains 4.2 mg/100mg.
However,
even though many leafy vegetables are rich in Iron, it is a
form of Iron (Non-Heme) that is not absorbed by the body as
easily as the heme form of iron. The form of iron present in
liver, red meat, egg etc. is( heme iron) a type which the body
can directly use. It has been found that a diet high in animal
foods like meat and fish has a higher absorption is 10-20% compared
to a vegetarian diet which has a low level of absorption in
the range of 2-5%.
The
real benefits of green leafy vegetables go way beyond their
Iron content. Green leafy vegetables are rich in omega-3-fats,
calcium, beta carotene, vitamin C and folic acid.Omega-3 fats
are useful in controlling blood pressure, blood fats and heart
disease,theyare useful for healthy skin and hair. Vitamin C
is useful for immunity and disease prevention as it is an antioxidant.
Beta-carotene is also useful in preventing night blindness and
is a powerful antioxidant vitamin. Folic acid is useful in treatment
of anemia and preventing heart disease and ageing.
For
improving iron status make sure you add vitamin C rich foods
along, like squeeze of lime or amla or a fruit to enhance absorption.
Go for atleast 50-100 gms of a green leafy vegetable for it’s
truly a SuperFood.
Refined oils
are good for the heart and health
Fats
are an essential part of the diet and a storehouse of energy,
supply essential fatty acids (needed to live) and transport
fat soluble vitamins. Besides this, fats are also an important
part of diet as they provide a feeling of fullness and satiety,
which is needed to regulate appetite. However, excessive amounts
or poor quality fats in the diet can cause several problems
including obesity, heart disease, cancer, skin and immune
problems.
Refining
of oils is done to produce oils on a mass scale for commercial
purposes and therefore maximize yields and shelf life. Native,
natural oilseeds are heated to a very high heat (temperatures
may be more than 200°C) and oil is then extracted through
a solvent extraction process. Subsequently the oil is degummed,
clarified and deodorized to obtain the so called “lite”
look and taste. This high heat destroys most of the essential
fatty acids (the reason why one needs fat), natural vitamins
including Vitamin E and antioxidants. Even the lecithin, a
fat emulsifier, present in oil is removed and sold separately
to the food industry. The oil thus obtained, ripped off its
antioxidants tends to become very unstable and prone to rancidity.
Therefore, then it is further subjected to a process of hydrogenation
to increase its shelf life. This process is seriously harmful
to health as it causes formation of “trans fatty acids” which
increase risk to coronary artery disease. Vanaspati, reused
fried oils and margarines used in bakery products are other
sources of hydrogenated fats. It is also known that often
solvent extraction process leaves traces of solvent which
is cancer causing in the oil. In addition, chemical preservatives
are also added to extend shelf life. The net result is a fatty,
refined, clear, odorless product with a long shelf life. Unfortunately,
such oils have taken up most of the shelf space of grocery
stores selling fats. They have almost completely replaced
traditional fats used by our ancestors.
Cold
pressed oils on the other hand are extracted at room temperature
without employing high temperatures and chemicals. They retain
the natural goodness of the oil. The traditional methods called
“Kachchi Ghani” is one such example.Olive, Mustard, Sesame
are cold pressed oils used in traditional households. Part
of the popularity of olive oil stems from the fact that it
is cold pressed oil.
Another
important aspect of oil selection is whether it is organic
or not. Oil seeds are commonly exposed to several chemical
sprays and pesticides like DDT, BHC which are fat soluble.
Therefore, oils extracted from them carry significant amounts
of pesticide residues. When consumed on a regular basis these
residues are known to get deposited in vital organs like liver,
kidney and brain and fat tissue. Over a period of time, they
can result in what is called cumulative toxicity leading to
organ damage and several health problems including cancer,
infertility and birth defects. It is therefore, advisable
to use organic cold pressed oils wherever possible.
A
combination of oils is preferred over a single one to balance
the nutritional requirements of polyunsaturated, monounsaturated
and saturated fats. A prudent choice would be a combination
of mustard, sesame and desi ghee in equal proportions. For
those who can use olive oil it is advisable to make it a part
of cooking media. These oils need not be mixed but different
oils could be used in different preparations.
Frying
in fresh oil in the house occasionally may be done without
heating the oil to very high temperatures. Olive oil is not
suitable for frying due to its low smoking point. Oil used
for more than half an hour should not be reused. Buy small
quantities at a time and store oils in dark glass containers
away from heat and sunlight. This means that it is advisable
to transfer the oil from commercial plastic containers to
your own glass containers.
For
those who have health problems are obese or inactive it is
advisable to limit fat intake. However, it is most important
to choose the right quality of oil and avoid refined, hydrogenated
and reused oils.
