Whey Protein Facts & Information

Some interesting facts:










What is whey protein?

Whey protein is a high-quality protein naturally found in dairy. It is a byproduct of cheese. After milk is processes into cheese, a liquid called milk plasma remains. Whey is extracted from milk plasma. It is a complete protein containing all of the essential amino acids ("building blocks") your body needs and is easy to digest. Whey protein is also one of the best sources of branched-chain amino acids (BCAA) including leucine, which has been shown to stimulate muscle synthesis.


Whey protein is the highest quality and most nutritious protein available. Comprised of approximately 80% casein and 20% whey proteins, it is sometimes called the "fast protein" because of its quick metabolic absorption and speed of nourishment delivery to muscles. Whey protein powder is highly soluble and efficiently absorbed by the body.


Valued by athletes and people that exercise, whey protein powder has the highest known biological value of any protein. Whey's proportion of proteins that can be absorbed and incorporated into the proteins of the body is very high.


Whey protein powder is the best source of the natural branched chain amino acids; leucine, isoleucine, and valine that are important to boost energy. The branched chain amino acids are central to fighting fatigue and aiding in recovery during and after exercise. They are burned at higher levels by active bodies, thus requiring active poeple to consume more of them.


Proteins are made of essential and non essential amino acids. They serve to repair cells and control many metabolic functions. Proteins are the body's source of energy and function to build and repair muscles and bones.


The human body organically manufactures non essential amino acids, but can only get essential amino acids from the consumption of high quality protein foods like whey protein powder. Whey protein is a naturally complete protein. This means it contains all of the essential amino acids.


Whey protein powder comes in three forms; concentrate, isolates and hydrolysates. Isolates is whey's purest form containing about 90% pure protein and virtually no lactose or fat. It is sometimes flavored and most commonly consumed by dissolving in milk or water to drink.


Whey protein can be an effective general health tool and aid in weight loss. Whey protein powder isolate's combination of high protein content and lack of fat, make it attractive to those trying to lose weight. Whey protein also has high levels of glutathione, an antioxidant required for a healthy immune system. Because of this, whey protein powder can be very beneficial to those battling degenerative disease. Being a pure and complete protein, it is also thought to help regulate blood sugar levels benefiting the management of diabetes.


How is whey protein made?

Whey is one of two major proteins found in cow's milk. Whey protein is produced during the process of making cheese, which begins when special enzymes are added to milk causing it to separate. The curds are used to make cheese, leaving behind whey protein in the liquid portion. This liquid whey is then pasteurized and dried into a powder for various uses.


Who benefits from whey protein?

Many people can benefit from adding whey protein to their diet. Healthy, active adults who partake in resistance exercise may find that whey protein helps to improve body composition by helping to increase the rate at which the body makes lean muscle. Whey protein may also help those trying to manage body weight because it is a natural and convenient way of adding protein to the diet. Diets high in protein have been shown to help people feel fuller longer, which may reduce the desire to snack or over-eat, leading to decreased caloric intake. Higher protein, reduced calorie diets have also been shown to improve the quality of weight loss by increasing the loss of body fat and/or reducing the loss of lean muscle. In addition, starting at about the age of forty, muscle mass begins to decline, but including whey protein at each meal can be an easy and healthy way to help minimize this loss.


Are some protein sources better than others?

The quality of protein varies. High-quality, "complete" protein sources include animal-based proteins such as meat, fish, poultry, eggs, milk, cheese, yogurt, and whey protein. These foods supply all of the essential amino acids the body needs to build and maintain muscle and to function properly. Protein found in most plant foods, including legumes, seeds, nuts, vegetables, and grain products, is considered "incomplete" protein because it lacks some of the essential amino acids needed daily.


How much whey protein does a person need?

Most people need at least 0.4 grams of protein for every pound of body weight to meet basic protein requirements. Although most people meet minimum protein requirements, athletic individuals and older adults may benefit from a higher protein intake. So if you regularly engage in endurance exercise or strength training, you may benefit from up to twice this amount.


Can a person get too much protein?

The Institute of Medicine recommends that 10 to 35 percent of the total calories we consume each day should come from protein (see "Side effects" for possible symptoms of too much proteins). Although most people meet minimum protein requirements, athletic individuals and older adults may benefit from a higher protein intake.


What is the difference between whey protein concentrate, whey protein isolate, and hydrolyzed whey protein?

Whey protein isolate contains a higher concentration of protein per gram than whey protein concentrate because other ingredients, including lactose, fat, and some vitamins and minerals, are removed. Both offer health benefits and are used in various foods and powders. Hydrolyzed whey protein is created when the protein chains are broken down into smaller chains of amino acids called "peptides." This form of whey protein is most commonly used in infant formulas, medical protein supplements, and some sports drinks.


Can people who are lactose intolerant eat whey protein?

If you are lactose intolerant, or sensitive to lactose, the natural sugar found in milk products, you may be able to tolerate whey protein isolate, which contains very little lactose. The amount of lactose in whey protein concentrate is higher. As always, it is important to contact the manufacturer as lactose content can vary from product to product.


Does whey protein contain gluten or wheat protein?

Whey protein does not contain any wheat protein or gluten. However, whey protein bars and beverages often contain added wheat-based ingredients, so be sure to check the ingredients list.


Does whey protein have a gritty or unpleasant taste like some other protein powders?

Whey protein has a clean, neutral flavor. When used in food manufacturing, it adds little or no taste. Whey protein dissolves easily in liquids and does not have a gritty mouth feel.


Where can whey protein be found?

Whey protein can be found in powders, drink mixes, energy bars, yogurt, and other foods. Products with whey protein as a major source of protein will list "whey protein isolate," "whey protein concentrate," or "hydrolyzed whey protein" near the beginning of the ingredients list. Whey protein powder is very convenient and can be added to smoothies, oatmeal, soups, sauces, dips, baked goods, or other common foods.


What are the health benefits of whey protein?

Protein synthesis is one of the most important process when it comes to human body growth, and this very fact highlights the importance of proteins in our body. In case of most of the protein rich foods, you also tend get some unwanted fats and carbohydrates, which are not quite healthy for your body, along with them. In such circumstances, finding a source of protein which will provide the necessary amount of this nutrient, without adding any sort of harmful components to your body, can be a boon in itself, and this is exactly what whey protein does. Given below are some whey protein benefits which are bound to make you realize the importance of whey protein in your daily diet.


Whey protein for healthy immune system

Studies reveal that athletic individuals require twice the amount of protein than the recommended daily allowance (RDA), and hence whey protein is the best option for them. Whey protein is also referred to as complete protein owing to the fact that it doesn't just contain all the amino-acids, but contains them in a proportionately required amount as well. It also helps in boosting the immune system by increasing the levels of glutathione - an antioxidant required by the body. More importantly, whey protein being soluble ensures that it is easily absorbed by the body.

Whey protein for weight loss

Maintaining proper weight is yet another crucial aspect of healthy living, and whey protein helps in this aspect as well. Whey protein has very little, or no fat or carbohydrates at all. This means it's an important source of protein, without extra calories that add to your weight. In fact, the efforts taken by the body to digest proteins ensures that more calories are burned. It also stabilizes blood glucose levels, which in turn reduces hunger and helps to body to burn fat.

Other whey protein powder benefits:


These were some of the most prominent whey protein benefits, which highlight the importance of including it in our daily diet. However, one should also make a note of the fact that consumption of whey protein in excess can result in some side effects on the body. These whey protein side effects may range from simple allergies to damage of the liver, and therefore one has to take some precautions when including whey protein in the daily diet. Ideally, you should consult a dietitian when resorting to whey protein for those extra health benefits of the same.


What are the dangers and side effects of whey protein?

Though the benefits of whey protein are numerous, it must be taken as per the recommended dose. Since whey protein side effects could arise in event of adverse drug interactions, make sure that you inform your health care provider about the other drugs that you may be taking. Some of the medicines that can cause drug interactions with whey protein are tetracycline, norflaxacin and levodopa. Those of you who have been suffering from any chronic diseases or are allergic to dairy products must also consult a doctor before taking whey protein. Headache, nausea, fatigue, loss of appetite and cramps are some of the common side effects that may be caused by excessive consumption of whey protein.


Before you start taking whey protein, make sure that you learn about whey protein dangers. Here's some information on the effects of overdosing on whey protein.

Allergic reaction

Whey protein may cause an allergic reaction in people who are lactose-intolerant. Whey is derived from milk that contains small amounts of lactose. If you are not capable of digesting lactose, then whey protein can cause abdominal bloating, cramps, nausea or diarrhea. Since the fat and lactose content is minimal in whey protein isolate in comparison to whey protein concentrate, it would be best to take whey protein isolate. It is always advisable to consult a dietitian to know the right amount of whey protein that can be consumed.


Kidney problems

It is believed by experts that excessive consumption of whey protein can cause kidney problems. Kidneys act as filters of the body and remove the wastes. If whey protein is consumed in excess, it may enhance the pH of the blood and increase acidity in the blood. As a result, kidneys may not be able to metabolize these proteins. Though, this evidence is not scientifically proven, there are chances that your kidneys may get affected.

Liver damage

Whey protein can also damage the liver. It is believed that accumulation of excessive whey protein increases the ketone level in the blood thereby causing ketosis of liver. Intake of protein causes more pressure on the liver, thereby damaging the liver.

Weakening of the bones

High concentration of whey protein can cause mineral imbalance in the bones. This changes the mineral bone density and can lead to primary stage of osteoporosis. Deficiency of calcium and collagen from bone can cause them to get weakened easily, thus leading to osteoporosis. People who take excess amounts of whey protein are also at an increased risk of developing painful inflammation and rigidness of the bones and muscles. This could result from the accumulation of crystals of uric acid in the muscles, bones and tendons in the legs and feet.

Excess of anything is dangerous and whey protein is not an exception to it. After all, it is a dietary supplement. Therefore, a balanced diet with the right quantity of all the nutrients and regular exercise are together the key to your health and wellness. Except for allergies, all the above mentioned whey protein side effects are probable as none of them is scientifically proved. Besides being vital for muscle building, it has also proved beneficial in fat loss, in preventing dangerous diseases such as cancer and in increasing immunity. Yes, I would now say that go and buy yourself whey protein!, but see an expert dietitian before that and get that 'right quantity' prescribed.

Comment:

Using whey protein w/ Western meds and my own diet research, I no longer need new liver. I take one or two servings (25g protein/serving) of whey protein w/ BCAAs (branched chain amino acids) daily. It avoids the fat and is easy to digest. For me personally, my blood ammonia is a lot less than it was w/ meat or eggs. I have had TIPs (liver stent). I now take half the lactulose I used to. I had my MD take weekly blood ammonia readings while lowering my lactulose.

Comment:

I suffered from IBS [Irritable Bowel Syndrome] for over 30 years! I finally BEAT my IBS quite by accident when I started [an exercise] program and bought some WHEY PROTEIN to help me [build muscles]. Strangely enough, I suddenly found myself having normal daily bowel movements WITHOUT pain or diarhea for the first time in over 30 years since turning 11 years old. Even after stopping my daily [exercise program] three months ago I am still having normal, pain free, diarhea free daily bowel movements so it was not the exercise that contributed to my beating IBS. I have advised others to try it and they have reported the same results as myself. I have no idea why it works, I just KNOW that it does for me and perhaps it will help you as well.... Good Luck and my greatest hope for you is that you too can FINALLY lead a normal life as I do now! Norman Simpers Jr. Conover NC

Comment:

Helped me get more protein rapidly as I have a problem getting nutrients from my food and also want to lose weight, and have some digestive problems, so am trying to find a way to get the protein I need without eating more food. Peanut butter on whole wheat bread works best when it comes to preventing my legs from swelling (edema) and in raising my enerty levels. The whey protein does seem to make me feel more tired. I am trying to find the right balance, and it isn't easy.
