Some foods are often quite controversial, which makes it hard to generate a definitive determination as to their advantage for health. Casein drops into this “grey” category, where the grade of the source and your main health goal require careful consideration.
Casein is the main protein in raw milk, which makes up about 80 percent of its protein . Another 20 percent is whey. Whey protein has a reputation as healthy exercise protein that support athletic performance and muscle development, and is a common ingredient in sport nutrition powders, pubs and drinks.
A key difference between whey and casein is that vitamin is digested very quickly, which makes it an perfect recovery meal whereas casein is a slow-digesting protein using anti-catabolic properties, meaning it helps decrease muscle breakdown, also in the absence of food.
Whey also has one of the highest concentrations of the branched chain amino acids leucine, isoleucine and valine, which are powerful stimulators of muscle development via activation of the mTOR pathway.
Types and Types of Casein
The two main types of casein are all micellar casein — the most popular form in sport nutrition — also casein hydrolysate, which is predigested and more rapidly absorbed than micellar casein.
Casein can likewise be separated into three chief types: native entire milk casein from raw cheese, milk casein and industrial casein. According to fitness pro Ori Hofmekler, author of “Unlock Your Own Muscle Gene,” there are significant differences between these 3 different types.
Casein is normally expressed using heat or acid processing, and there is a significant part of the issue. Many casein products available on the market are poor in grade, and may even contain toxic residues. As for its own value as a beneficial protein for muscle gain, opinions and scientific proof varies dependent on the particulars.
Hofmekler notes that while native entire milk casein (consisting of protein clusters known as micelles, jumped together with calcium, phosphate and citrate ions) would be the most practical, as it “complements your own body’s acid-base equilibrium and will not result in an exceedingly acidifying effect,” the exact same cannot be said for industrial caseins, which can be exceptionally acidifying.
Moreover, many have casein sensitivities, and if you fall into this category, you would probably wish to prevent casein supplements no matter how large the quality. Frequent side effects of casein include intake or heart burn, bloating, allergic reactions or bad aftertaste.
Protein supplements such as casein can also be contraindicated for those who have kidney of liver disease, because they need to be aware of restricting their protein consumption.
Remember to Avoid Over-Consuming Protein
Having said that, I feel a strong case could be made that ALL people can gain from restricting protein to just what your body requires. If you are an athlete or bodybuilder, then you really do need more, however eating a great deal of protein could backfire, because you are picking physical functionality over long-term wellbeing and longevity.
A close ideal protein consumption may be around 1 g of protein per pound of lean body mass. Trainers, pregnant women and older people need about 25 percent more.
Eating more protein than your body actually needs can provoke a significant biochemical pathway known as the mammalian target of rapamycin (mTOR). This pathway has an essential part in several cancers.
When you reduce protein into what your body needs, mTOR stays vaccinated, which can help decrease your chances of cancer development.
That Casein Is Your Ideal?
Native American casein made from raw milk has distinct anabolic attributes, which makes it an effective muscle-building protein. Due to the slow absorption, also it offers a sustained release of amino acids into your blood flow for many hours.
Therefore it can be employed to keep your muscles at a sustained anabolic manner for a lengthy time period, such as during sleep. Whole milk casein additionally supplies leucine,1,two which a effective muscle builder when obtained from whole food. Products that are similar to indigenous casein are:
•Milk protein concentrate (MPC), an secure, entire protein created by membrane filtration of milk. This filtration yields an end product that includes casein and vitamin at ratios nearly like that at the milk.
MPC has almost identical attributes as native casein, also its own neutral-to-alkaline pH and secure, water-soluble condition makes it immune to heat damage. The very best MPC products are derived from raw milk in natural, cows that are parasitic.
•Micellar casein is processed in an identical way as MPC, however the casein micelles are separated in the amino via microfiltration. This enhances its functional value, as micellar casein has inferior water-solubility.
Generally, a protein powder needs to be reconstituted using liquid, and if it can’t dissolve fully, it loses functional value.
It is possible to increase solubility by using liquid. However, micellar casein can be unstable, and tends to deteriorate if stored within time. As stated by Hofmekler: “Micelles’ interactions contribute to cross-linking of fatsand migration of fat particles into the surface, and also degradation of these casein.
This usually means that although micellar casein has been acclaimed to be superior to additional industrial caseins, it’s yet unstable and therefore poor to native casein and cheese casein. And it may contain undesirable additive residues, such as legumes, sodium caseinate and polydextrose.”
He recommends doing your homework prior to purchasing a micellar casein product, and inquire the item supplier for an updated certificate of analysis (CofA) along with an independent laboratory report to prove the product’s protein integrity.
Coffee and Cheese Casein Versus Industrial Casein (Protein Isolates)
Cheese casein differs from raw milk casein, but it too has beneficial muscle-building properties. Cheese casein is obtained in the production of cheese — the curd that remains from the process is an entire, complete protein.
Becoming similar to native casein, it gives a slow and effective nutrient shipping. According to Hofmekler, industrial caseins are best avoided. Unlike indigenous casein and cheese casein, industrial caseins are all protein isolates, most of which are expressed from ultra-pasteurized milk using extreme acid and/or heat processing.
The processing typically yields a protein that’s deficient in methionine (an essential amino acid) and cysteine (a conditionally essential amino acid). Both are destroyed during the processing, and those sulfur-containing amino acids are very essential for optimum immune function.
What is worse, ultra thermolyzed (ultra-heated) casein was linked to increased probability of colon cancer. 3,4,5 It is a highly denatured protein that cannot be fully digested. As a result, undigested protein can reach your colon, where bacteria ferment the protein into carcinogenic phenolic compounds. 6 Hofmekler describes:
“Technically, heated protein gets carcinogenic due to fluctuations in their molecular integrity; decreased digestibility and enhanced oxygen waste. The reduced digestibility of cooked proteins increases the loading of nitrogenous waste substance reaching the colon via fermentation to ammonia and phenols — both of which are also cancer promoters.”
It is possible to counteract this threat to a level by eating loads of digestive-resistant starches and other soluble fibers. These function as substrates to feed beneficial gut bacteria and increase carbohydrate fermentation on your colon. By feeding these helpful bacteria, you also decrease the level of colonic protein cessation — along with the danger of colon cancer.
Benefits of High-Quality Casein
As mentioned, diminished muscle breakdown is just one of casein’s main advantages. A recent article from Authority Nutrition delves into some of the proposed advantages of casein, also describes the science behind its muscle-sparing effects therefore:7
“In 1 analysis,8 researchers gave participants whey or casein protein and then measured their complete breakdown rate for its amino acid leucine on a seven-hour period. They found the entire breakdown rate of leucine was around 25 percent greater compared to whey protein category.
This usually means that the casein group decreased the complete quantity of protein burned for gasoline on a seven-hour period. That usually means an improved online protein balance, an integral factor for muscle growth and retention. 9 Bottom Line: This protein is also anti-catabolic. It reduces protein breakdown over the body due to the slow digestion rate and sustained supply of amino acids into muscle cells”
Preliminary studies Also Have found casein can provide additional health benefits aside from muscular growth and muscle-sparing, including the following:
- Antibacterial activity
- Improved immune function10
- Lowered triglyceride levels11
- Antioxidant effects12,13
- Greater fat loss14
Why I Do Not Favor Casein Supplements
As for me, I don’t recommend casein supplements. High-quality whey protein out of natural grass-fed cows is my taste. My objections into casein could be outlined as follows:
•Many have casein sensitivity, and in these instances, you will probably encounter problems even in case you apply the very best, highest-quality casein available on the marketplace.
•Milk is very full of sugars (galactose), so you can quickly wind up with a top carbohydrate count (total carbohydrates minus fiber) if consuming raw milk. (berry is much better than milk in this respect, as it is reduced in galactose and higher in healthy fats)
•you’ve got milk-derived opioid receptors in your brain, and casein includes organic opioids called casomorphins. 15 (That is why you can become “hooked” to milk products like milk and cheese.) We know that low-dose naltrexone (LDN) is very effective for boosting immune function by blocking these receptors. Conversely, by always stimulating these adrenal glands, you can potentially interrupt your immune function.
As explained by Dr. Thomas Cowan, a family doctor and founding board member of the Weston A. Price Foundation (WAPF), who’s well-versed in the use of both LDN for autoimmune disorders, exogenous opiates (opiates from outside sources; not naturally produced from the body) are in fact potent immune suppressors.
A famous study known as the European Prostitute Study showed the primary risk factor for HIV and AIDS was not sexual exposure, not IV exposure, however opiate exposure. According to Cowan, you find an identical pattern in cancer sufferers. After they start taking opiates for chronic pain, their health rapidly declines because their immune system falters.
Therefore, if you are immune challenged, it would be wise to avoid casein entirely, and for people that aren’t, it might be a good idea to limit its use to times if you require extra protein for strength training. But I personally believe whey protein is also a superior option for it.
•Casein can indeed succeed for muscle development. However, there is a decision to be made: Either you are optimizing functionality, or you are optimizing health and longevity.
Used occasionally and in limited amounts, it is not possible to do any significant injury and may gain your athletic performance, however “protein loading” in general to maximize muscle can increase your risk of long-term health issues such as cancer (from arousing mTOR), also if using casein in surplus, it could potentially have an adverse effect on your immune system.
•Last but not the least, so many of these casein supplements in the marketplace are of inferior quality, either due to their source or the processing. The more a protein is heated the more degraded and poisonous it gets. Therefore, in the event you decide to choose a protein supplement, then make sure that it doesn’t include thermolyzed (heat-treated) casein, which has revealed to be the most carcinogenic among thermolyzed foods. Including casein and whey isolates in addition to all caseinates. 16
Additionally avoid vitamin proteins derived from ultra-pasteurized milk. If the whey maker fails to provide you with a certification of conformity (CoC) that clearly declares their whey is produced from raw milk, then it has probably been ultra-pasteurized.
Final Notes
As you can see, there are pros and cons to take into account. At bare minimum, you would be wise to get your homework to make sure you’re getting a premium quality casein supplement should you decide you want to use it as a muscle building promoter. Your best options are native casein found in raw milk, cheese and cheese casein located in aged cheese and cottage cheese. A close alternate is MPC.
Just be aware of the fact that excessive use — especially if you’re using a heat-treated or otherwise poor quality product — could have drawbacks, possibly raising your risk of certain health problems, including lowered immune functioning and colon cancer.
Others may disagree with those decisions, and I admit I’ve not firmly established a base of evidence against the use of casein. However, I’ve got my feelings, which will remain until or until I find enough evidence to alter or discard them entirely.
