Proteins are one of the most fascinating groups of molecules in the human body. They are complex combinations smaller chemical compounds called amino acids.

It
is the primary component of muscles, organs and glands. The cells of
muscles, tendons, and ligaments are maintained with protein. Along with
fat and carbohydrates, protein is a “macronutrient”; it means that the
body needs relatively large amounts of it. There are three groups of
protein containing foods.

High
protein foods like red meats, egg, fish and cheese. Medium protein food
such as rice, wheat oats and barley and low protein foods includes
fruit vegetables and juices. In addition to these sources other people
like to use protein supplements such as protein powders, protein bars,
meal replacements, hydrolyzed or pre-digested protein and amino acid
supplements. Protein supplements generally contain more than 20 to 30
grams of protein per serving, and are fortified with vitamins and
minerals. It can also come in numerous flavors, from fruit flavored
protein powders, to cookie and cream flavored weight gainers to peanut
butter flavored protein bars.

Although the advantages of taking protein supplements
does not measure up to those you will get from real foods they are in
the second place. Active persons like athletes, bodybuilders or those
who love to work out and build muscles consume protein supplements to
promote muscle strength, function and possibly size. The need to
increase daily protein intake while on a training program helps to
increase muscle mass. Maintaining a body with protein positive nitrogen
balance is a must to enable to repair and replace muscle tissue. Protein
is also needed to keep a balanced PH in the blood. It can also be an
energy source when there are no carbohydrates available.

According to Angela Lang of www.livestrong.com,
if you cannot consume adequate amounts of protein, a supplement like
protein powder can be convenient source of nourishment. One of protein
supplements advantages is losing weight. It makes you feel fuller but
with fewer total calories than food rich in carbohydrates or fats. The
human body has to work thirty percent harder to digest protein foods
then it does to digest and process carbs and fats. For this reason, a
high protein diet boosts your metabolism and aids in fat loss. Even if
you are losing weight, a high protein intake with the help of protein supplements can make you gain muscle mass and strength and it can also reduce muscle loss.
Protein
supplements help stabilize blood sugar level. While eating high-carb
and high-sugar foods that results in fluctuations in blood sugar levels,
eating protein does the opposite. Eating foods with protein can also
slow down the absorption of sugar during a meal, which is especially
important for preventing two types of diabetes, balancing energy levels
and keeping your appetite and mood in check.
Protein supplements
are more convenient, and require little to no cleanup. It is also much
temperature sensitive and generally requires no refrigeration or
heating. They are often fortified with vitamins and minerals and are
multi0dimensional protein food and can be cost effective. Protein
supplements are generally grab and go. They can go where you go and can
provide you with the ability to have a fast or slow digesting protein
meal whenever you need it.
