The Benefits Of Protein

1) IT BUILDS, MAINTAINS AND REPAIRS CELLS:- Protein is referred to as your body’s building blocks for good reason. As you grow your body needs protein to construct every single cell including your bones, your muscles, your skin, your vital organs and your blood vessels. When you are fully grown your body still needs protein to maintain all these cells and also to replace any cells that fall off such as hair, nails and skin. Protein is also required to repair any cells that become damaged. For example, if one of your blood vessels burst or one of your bones break protein is required to repair them.

2) IT IS USED TO PRODUCE IMPORTANT CHEMICALS:- Your body uses protein to produce a number of important chemicals. Antibodies are built using protein and are a key part of your immune system which helps your body fight disease. Enzymes are also constructed from protein and act as a catalyst for many important reactions in your body including digestion. Protein is also used to create hormones which act as chemical messengers in your body and stimulate a specific response from certain cells. 

3) IT REGULATES IMPORTANT BODILY PROCESSES:- Protein is not just used by your body to produce cells and chemicals. It also regulates certain important processes in your body. One example of this is fluid balance. Your body’s cells cannot move fluid directly. Instead they produce proteins which attract water. These proteins can then be sent out to areas where fluid needs to be absorbed allowing a fluid balance to be maintained throughout the body.

4) IT HELPS YOUR BLOOD CLOT:- Your body also uses protein to prevent your wounds from bleeding continuously. When your skin gets cut and starts to bleed your body responds by producing fibrin, a stringy protein that forms a clot. Once the fibrin has clotted your body then produces another protein, collagen which forms scar tissue and permanently heals the cut.

5) IT CAN ASSIST WITH WEIGHT LOSS:- Not only does protein perform all the important roles listed above but it can also be a great food choice for people who are trying to lose weight. First, it has a greater thermic effect than carbohydrates. This means that by eating protein you burn more calories during digestion and boost your metabolism. Secondly, studies suggest that protein can suppress your appetite. Although more research needs to be done into exactly why protein has this effect this study suggests that the amino acid leucine has a huge effect on appetite.


The Disadvantages of Consuming Too Much Protein

Although protein is a fantastic macronutrient that acts as the building blocks for your body, protein is is not without its faults. Consuming too much protein can cause a number of health problems. In this article I will be discussing some of the potential problems associated with overdosing on protein in greater detail.

1) IT CAN CAUSE DEHYDRATION:- According to this study increasing your protein intake can also increase levels of dehydration. The study looked at five endurance athletes who consumed low, moderate and high levels of protein over a period of four weeks. The findings revealed that as protein intake went up, hydration levels went down. Dehydration can put you at risk for a number of health problems and heat related illnesses.

2) IT CAN INCREASE FAT STORAGE:- One of the common misconceptions surrounding protein is that you can eat as much as you like and you will not get fat. However, the simple truth is that if you eat too many calories (whether they be carbohydrate calories, protein calories or fat calories) any excess will be stored as body fat. Increasing your protein intake and reducing your carbohydrate intake whilst staying within the limits of your daily metabolism can stimulate fat burning in your body. However, increasing your overall caloric intake by eating more protein will ultimately lead to fat storage.
 
3) IT CAN CAUSE DIABETIC KETOACIDOSIS:- Eating high levels of protein and low levels of carbohydrates causes your body to enter a state of ketosis. This is a state where there is no glucose available in your blood in your blood to use for energy. Since there is no glucose available your liver starts to convert body fat into fatty acids and ketones which can then be used for energy. Whilst this is a popular fat loss method it can also be dangerous for diabetic people. Ketones are acidic and can therefore cause a number of problems including nausea, vomiting and even death. In non-diabetic people blood ketone levels are controlled by insulin. However, diabetic people struggle to produce adequate levels of insulin and ketosis can quickly turn into ketoacidosis, a state where the level of ketones in your blood is extremely high. This then leads to the problems discussed above.

4) IT CAN LEAD TO KIDNEY STONES:- Studies suggest that high protein diets (particularly those high in meat protein) may be partially to blame for kidney stones. The reason for this is that when you consume protein it is broken down into acids including uric acid. This then increases the overall acidity of your blood. Your responds by releasing the alkaline substance calcium phosphate from the bones into the bloodstream. Ultimately, this can then lead to an increase in urine levels of both uric acid and calcium. These substances may then form into insoluble crystals (kidney stones) which are excreted in the urine.

5) IT CAN CAUSE OSTEOPOROSIS:- As I mentioned above eating high levels of protein can ultimately cause your body to release calcium phosphate from the bones. A lack of calcium in the bones can then lead to a condition called osteoporosis where your bone density becomes reduced. Osteoporosis causes your bones to bend, break and fracture much more easily than someone without the condition.
