Your muscles need protein in order to grow. Without it, you'd be shaped more like Skeletor than He-Man (not a good look, if you ask us). Daily doses of protein are imperative if you're looking to improve your health and physique
Chemically speaking, a protein is composed of amino acids covalently bonded through peptide bonds to form a chain. It has a number of functions within and out of the cells such as structural roles, acting as catalyst, transporting ferry ions and molecules across membranes and hormones.
Nutritionally, protein is a macronutrient which assists in building up and repairing muscles and bones. It is the building block of life and the body needs it to repair and maintain itself. Every cell in the body including body fluids contains protein with the exception of the bile and urine. Human growth and development especially during pregnancy require protein to be successful.
ScienceDaily.com, an online resource of new scientific discoveries, recently revealed that it is protein and not sugar that keeps us thin and awake. Scientists from the University of Cambridge discovered that wakefulness and energy expenditures actually relied on orexin cells. These cells secrete a substance that stimulates the brain. When these cells malfunction, sleep disorders set in. Orexin cells also influence our energy levels. When scientists studied what nutrient orexin cells responded to, they discovered that proteins stimulate the orexin cells more than any other nutrient. They further discovered that while glucose blocks the action of orexin cells, amino acids, when they interfered, negated the effect of glucose.
In a 2005 study, it was settled that elevating protein intake helps reduce body weight faster than limiting carbohydrate consumption. This practically explains what we have already observed: protein-rich meals make people more alert than sugar-rich meals.
Protein Intake Recommendations
The RDA for healthy adults (0.8 g/kg body weight per day) was created to allow for an individual's differences in protein metabolism-since people's metabolic rate can vary due to numerous factors. That recommendation for protein intake covers that vast majority of society-approximately 97.5%- which may be adequate for non-exercising individuals. Since exercise breaks down additional foodstuffs coming from protein, carbohydrates and fats, trained individuals require more calories-especially coming from protein to accommodate recovery and muscle maintenance
Protein Quality And Common Types Of Protein Supplements
Not all proteins are the same. Proteins that contain all the amino acids required to create new proteins are called complete proteins. Animal sources of meat are usually complete proteins. If you should choose to enjoy your protein from meat, choose the leanest proteins; those with the least amount of fat and calories. Best sources of this kind are fish, skinless chicken or turkey and eggs. If it should be red meat, choose the leanest cuts like loin and tenderloin.
Another kind of protein is incomplete protein. This type lacks one or more essential amino acids unlike complete proteins. They are usually found in fruits, vegetables, nuts and grains. This type of protein may lack one or more amino acids needed to make new protein. Vegetarians and vegans are thus encouraged to enjoy a variety of protein rich foods in order to keep the body’s system in good shape and should consider having a good serving of beans, legumes, soy foods and soy milk.
Another healthy option to consider is protein powders.
