The word casein is derived from the Latin caseus, meaning cheese. It accounts for almost 80% of proteins found in milk and in cheese. A good source of cheese casein is Cottage cheese. The predominant protein is called phosphoprotein.
Casein is a derivative of Whey protein and has recently shown itself to be an excellent source of protein in order to help the body recover from excess stress, injury or exhaustion as can be caused by intensive athletic training. This is due to the fact that it empties from the stomach quickly yet the body takes longer to digest it, making absorption more efficient. How it does this is by forming a clot in the stomach. It is this clot that provides the sustained release of amino acids into the blood as well as helping the body retain nitrogen.
The clotting is due to Casein proteins being pH sensitive, which makes them 'gel', or clot in an acidic environment, such as the stomach. This slower rate of digestion is what makes Casein so beneficial. While quickly absorbing proteins have their place immediately before of after a workout, Casein proteins take it a step further by protecting, repairing and nourishing your body throughout the day.
Benefits of Casein Protein
Casein is used extensively by athletes as a dietary supplement as it breaks down slowly which gives them a sustained release of protein. It also provides anti-catabolic properties, which inhibit protein breakdown which is crucial for sports men and women.
Yet Casein is not only suited to athletes. Everybody needs to provide enough protein in their diet. However many are not able to get it from food and as such Casein is a good source when taken as a supplement.
Casein is known as the slow and fast acting protein. It is quickly metabolized in the body yet our bodies take longer to digest it. This unique property of Casein provides many specific benefits.
Casein helps preserve muscles. Apart from building muscle instead of fat we need to maintain muscle. Casein also helps blood flow faster and equally around the body.
Casein increases metabolism and provides glutamine, which is good for those who want to increase their weight. It is also said to reduce tooth decay.
Casein Foods
Casein is derived from and is a by product of milk products, especially cheese. During the curdling process Casein proteins are collected and then processed in their desired form.
Casein grading is important and can be divided into either high or low grade. Low quality Casein proteins are regarded as such because they are collected before the curdling phase. They are less expensive because they are less refined. The less refinement the longer they move through our body.
High quality proteins are derived from whole milk that contains no chemicals or acids.
The molecular structure of Casein is similar to that of Gluten. It is often listed as sodium Caseinate, calcium Caseinate or milk proteins. If one looks at the labeling on energy products they will most likely be seen on the packaging. They do however contain an amount of cow's milk and should be taken with caution by those who have dairy allergies.
One of the major Caseins in milk is beta-Casein. There is more than one type of beta-Casein yet the most common are typed as A1 and A2. Certain breeds of cow produce mostly A1 beta-Casein while other produces mostly A2 beta-Casein.
Casein as a meal replacement
Casein proteins improve how the body absorbs amino acids and because of this can provide maximum energy and strength when taken in place of a meal. They are able to help sustain the body for longer periods between meals.
In order to keep the body in prime condition it needs proteins derived from the foods we eat. This usually entails eating 6 small meals per day which are protein heavy. Yet for many it is not possible to get the required amount this way, especially with our busy lives. Yet we can get the extra proteins we need and which will keep our body functioning property through Casein supplements.
However before taking Casein as a supplement you should only consider taking those supplied by reputable manufacturers. You want to avoid low quality Casein proteins where possible. When you have tried both grades you will be able to gauge the difference.
