This presentation is about meat and meat protein. It's sources, components(Specially proteins). Here you can learn a lots about meat. What is meat? What is meat protein? How many types of meat available etc.

2. Before we start talking about
meat protein, we will discuss over
something very shortly which are
related to it. These are:
Basics of Protein
Sources of Protein
Meat
Classification of Meat
Composition of Meat

3. BASICS OF PROTEINS
Protein is one of those
three macronutrients
used by the body.
These macronutrients
are PROTEIN,
CARBOHYDRATES and
FATS. 20% of our body
made by protein.
Scientifically, protein
is a series of amino
acids linked together
like a chain. The links
that hold these
amino acids together
are known as
PEPTIDE LINKS.
Generally we can say
that, protein is the
“building blocks” of our
body. The main function
of protein is building of
new tissues and
maintenance and repair
body tissues.

4. SOURCES OF PROTEIN
Protein food sources are divided into two categories:
COMPLETE
PROTEIN
INCOMPLETE
PROTEIN
Contains all essential
amino acids. Animal
proteins (meat) are
complete protein
sources.
Foods from plant
(vegetables), lack
several essential
amino acids. This
lacking amino acids
vary from food
source to food
source.

5. ESSENTIAL
AMINO
ACIDS
Isoleucine
Histidine
Leucine
Methionine
Valine
Threonine
Tryptophan
Phenyla-
lanine
Lysine

6. MEAT
Flesh of animals, birds and their
edible internal organs is called
meat. There is a large range of
meat and meat products available
to purchase. The quality of the
meat will depend on how the
animal has been kept, what it is fed
on, its age and how it is processed
and cooked.

7. CLASSIFICATION
OF MEAT
Meat can be
divided into two categories
in the basis of
muscle color.
RED MEAT
Beef, Mutton, Lamb etc.
WHITE MEAT
Chicken, Turkey, Duck etc.

8. COMPOSITION OF MEAT
Nutrients in meat vary with
animal breed, feed, season and
position of meat cut. Meat
contains approximately 60-70%
water, 15-25% protein, 5-25% fat
with a small portion of
carbohydrates (1-5%), free
amino acids, dipeptides,
nucleotides and minerals.

9. Meat contains essential health promoting constituents like protein,
fats, micronutrients and omega-3 fatty acids.
Protein plays a wide range of functions that may be the structural,
contractile or enzymes which catalyze the chemical reactions.
Proteins contain carbon, nitrogen, oxygen, hydrogen and sulphur
compounds.
Meat such as beef is mainly made of protein. Meat is an excellent
source of protein, which is essential for any healthy diet. It helps
to build and repair muscle as well as help maintain healthy hair,
bones, skin and blood.
MEAT PROTEIN Meat is a very efficient deliverer of protein. Because the
muscles of animals and humans share the same
ccomponents,eating animal tissue is an easy way to get this
necessary nutrient.

10. Due to its High Biological Value (HBV), protein acquired from
meat is easily digested and absorbed quickly and effectively
by the body. Red meat, Chicken and Turkey are incredibly
high in protein. The protein contents of lean, cooked beef
ranges from 26-27%. The building blocks of proteins, the
amino acids, are very important from a health perspective.
Their composition in proteins varies widely, depending on the
dietary source.

11. MEAT PROTEIN
MEAT PROTEIN
Meat protein has some important physiological function
in our body too. These are blood-pressure regulation,
energy regulation, wound healing, development and
regulation of collagen, antibodies, hormones, and
enzymes production and many more.

12. Animal protein is normally high caliber, containing all 9
essential amino acids needed for the growth and
maintenance of our bodies. Meat is one of the most
complete dietary sources of protein. The amino acid profile
being almost identical to that of our own muscles. For this
reason, eating meat or other sources of animal protein,
may be of particular benefit after surgery and for
recovering athletes or during other conditions where
muscle tissue is being built.
MEAT PROTEIN

13. Conclusion
We know meat protein is very important for our
health. But we know our body set a limit for every
nutrient. Our body needs 0.65g protein per pound
body weight for normal body maintenances. If we
cross the limit and takes nutrients as much as we
like then it will be harmful for us. If we continuously
take more protein than our body need, we will be at
a risk of heart attack, stroke, high cholesterol,
obesity, diabetic’s type-2 etc.
So, we need to take protein in order to stay fit. But
we should be careful about how much our body
needs.
