Nutritional FUNCTION and Medicinal Properties of Wheat CONTAIN:
Abstract
Wheat is
considered good source of protein, minerals, B
-
group vitamins and dietary fiber i.e.
an excellent health
-
building food. Thus, it has
become the principal cereal, being more widely used for
the making of bread than any other cereal because of the quality and quantit
y of its
characteristic protein
called gluten.

virtues;
starch and gluten in wheat provide heat and energy; the inner bran coats, phosphates and other miner

needed roughage
the indigestible portion
that
helps easy movement of bowels; the germ, vitamins B and E; and protein of
wheat helps
build and repair muscular tissue. The wheat germ, which is removed in the process of refining, is al
so rich in essential vita
min E, the lack of
which can lead to heart disease. The loss of vitamins and minerals in the refined wheat flour has l
ed to widespread prevalence of constipation
and other digestive disturbances and nutritional disorders. The whole wheat, which includes bran and
wheat germ, therefore, p
rovides
protection against diseases such as constipation, ischaemic, heart disease, dis
ease of the colon called diverticulum, appendicitis, obesity and
diabetes.
To enhance the quality as well as the quantity of proteins/starches, and the content of vitamins, es
sential amino aci
ds, minerals and
other healthy
components of wheat, it is essen
tial to understand the molecular and genetic control of various aspects of plant growth and
development.

1. Introduction
Wheat is the most important stable food crop for more than one third of the world population and con
tributes more calories
and proteins to the world diet than any other cereal crops
[
2, 3,
42
]
.
It is nutritious, easy to store and transport and can be
processed into various types of food.
Wheat is considered a good source of protein, minerals, B
-
group vitamins and dietary fiber
[45, 46] although the environmental conditions can affect nutritional composition of wheat grains
with its essential coating of
bran, vitamins and minerals; it is an excellent health
-
building food.
Wheat flour is used to prepare bread, produce biscuits,
confectionary products, noodles and vital wheat gluten or seitan. Wheat is also used as animal feed,
for ethanol production,
brew
ing of wheat beer, wheat based raw material for cosmetics, wheat protein in meat substitutes and to
make wheat straw
composites
.
Wheat germ and wheat bran can be a good source of dietary fiber helping in the prevention and treatm
ent of some
digestive disor
ders
[46].
The antioxidant activity and phytochemical content were studied in milled grain of eleven varieties
which included a range of red and white wheat and durum wheat.
Whole
-
wheat bread is good for health. There is no doubt that
the adaptability and
high yields of wheat have contributed to its success, but these alone are not sufficient to account
for its
current dominance over much of the temperate world. The key
characteristic, which has given it an advantage over other
temperate crops,
is the uniqu
e properties of
dough
formed from wheat flours, which allow it to be processed into a range of
breads and other baked products (including cakes and biscuits), pasta and noodles, and other process
ed foods. These propertie
s
depend on the structures and inter
actions of the grain storage proteins, which together form the ‘gluten’ protein fraction.
Lutein
is the predominant carotenoids present in wheat [1] and the bran/germ fractions of wheat contained g
reater amounts of
carotenoids and antioxidant activity than
the endosperm fractions [4]. Lutein, along with zeaxanthin, is important for the health
of skin and eyes in humans.
The latest edition of the USDA’s Dietary Guidelines for Americans clearly states that all adults sho
uld eat at least three se
rvings
of whol
e grains every day.
It
helps in preventing both heart diseases and cancer, therefore, lower death rates. The protection
against heart disease may stem from whole grains, antioxidants, vitamins and phytochemicals, fiber o
r trace minerals.
Apparently, by imp
roving insulin sensitivity and decreasing the disordered insulin function people experience with met
abolic
syndrome, whole
grains
help prevent diabetes. The same substances in whole grains that protect against heart disease also
seem to help prevent severa
l kinds of cancer. Fiber and certain starches in whole grains ferment in the colon and form
substances that may block the cancer
-
promoting effects of bile acids
.
Moreover, scientists believe that other substances in
whole grains may affect hormone levels a
nd possibly lower the risk of hormone
-
related cancers like breast cancer. The many MORE HEALTH INFO VICSIT rotimifavour.blogspot.com
