Bodybuilders and weight trainers commonly use whey protein, to supplement their regular diets for the following two reasons
Unlike most other protein types, whey protein consists of a variety of essential amino acids which are absorbed by our body quickly. It is also low in lactose content and possesses numerous other health benefits. The powder could just be the supplement you need to meet your fitness goals.
Milk contains two kinds of protein predominantly – casein and whey. A mixture of proteins becomes isolated from whey during cheese production from milk. This protein mixture is known as whey protein.
Basically, the fatty substance in milk coagulates together during cheese production, and separates the whey, usually contained in the liquid portion of milk, as a by-product. For the longest time, cheesemakers would discard this whey, but not anymore. Now, whey protein is recognized for its nutritional value.
Whey protein powder usually contains added flavours, as it doesn’t taste very appetizing by itself. If you are considering buying whey protein powder though, make sure that it doesn’t have added sugar.
The protein content in it can easily supplement about 25-50 g of your protein intake. It’s an easy way for fitness enthusiasts, weight-loss hopefuls and other people, who lack adequate protein in their diet, to consume it. If you’ve happened to try flavoured whey protein, you wouldn’t want to miss out on this protein source. You can add it to your protein bars and shakes, or have it as a meal replacement.
Most people can consume whey protein without any problem. Some, however, like those with lactose intolerance or allergies may need to be careful.
One scoop (approx 32 g) of the average whey protein powder contains 113 calories, of which 4.5% is borrowed from the fat content.
Whey protein has several health benefits. We discuss a handful of these below.
It helps boost protein and BCAA intake by our body – Proteins are made up of amino acids. While a portion of our amino acid requirement is produced by the body itself, the rest has to be gathered from the food we eat.
The amino acids that our body derives from external food sources are called essential amino acids. Whey protein consists of nine essential amino acids. On top of that, they are rich in crucial branched-chain amino acids (BCAAs) such as leucine.
Leucine is a growth-promoting amino acid. It also contains cysteine which encourages glutathione levels, which is a cellular antioxidant. Whey protein is most effective for inducing growth in our bodies. Human breast milk, fed to newborns, is 60% whey as compared to cow’s milk, which contains only 20% whey.
With age one tends to have loss of muscle mass and strength. It is a serious health problem that diminishes bodily abilities and leads to physical dependence.
Studies show that whey protein increases muscle mass and strength by releasing anabolic hormones such as insulin, which is responsible for our muscle growth. The substance’s leucine content stimulates muscle protein synthesis in our body. Its protein and amino acids spur muscle growth. Whey protein, unlike other protein sources, generates muscle growth faster.
Whey protein is beneficial not just for adults. According to studies, infants who are made to consume this protein mixture in the initial 3-12 months show lower risks of developing red, itchy skin and allergic reactions easily later in life. However, once the child has grown up beyond that age, consuming whey protein will not affect their resistance to these conditions.
Whey protein has an incredible effect on satiety. Protein ranks highest among every macronutrient when it comes to satiety. It increases energy expenditure, balancing the number of calories you consume.
Studies have found that, if you eat 1/4th of your daily requirement in proteins, you slash down your hunger cravings by 60%. If you combine whey protein intake with weight lifting, you can lose about 8 pounds of your weight, increasing lean muscle mass at the same time. In addition to boosting your metabolism, it also shrinks your appetite and preserves lean muscle.
There’s enough documented evidence that shows protein consumption before and after a workout leads to a significant gain in muscle protein synthesis.
It plays a positive role in optimizing physical performance and subsequent recovery process for both resistance training and endurance exercise.
Studies prove that whey protein can help lower your total and LDL cholesterol more effectively than casein protein. Since cholesterol levels are directly related to various health conditions like strokes, whey protein keeps your heart healthy.
According to research, whey protein powder, when consumed by individuals with hypertension, has proven to be effective in reducing blood pressure, improving endothelial functions and regulating lipid profiles.
Whey protein has many other health benefits to boast. It contains anti-cancer properties, steps up immune function and may also protect against the symptoms of psoriasis to name a few.
Whey protein intake is generally considered safe for most adults when consumed in a proper dosage. However, overconsumption of the mixture may cause several digestive complaints like bloating, hyperactive bowel movements and diarrhoea.
You may also experience nausea, headaches, thirst, cramps, fatigue and a reduced appetite. You may end up with an acne problem if you are not careful in regulating your whey protein intake long-term. 1-2 scoops of the powder should be safe for consumption by most people.
Adequate research has not been conducted into how it affects pregnant women. So, it’s best to avoid the intake of whey protein if you happen to be pregnant or nursing. Additionally, if you happen to suffer from dairy allergies, its consumption may not be right for you.
Apart from the above, here are some other whey protein side effects:
If you happen to suffer from kidney issues, don’t consume whey protein. It could worsen your renal problems. It can cause kidney stones too.
To neutralize this side effect, you are recommended to consume adequate dietary fibre and water, as part of your diet.
Many whey protein powder offerings have sugar added, which adds to your carbohydrate consumption.
Some of them may also have fat added. So, instead of upping your protein intake to burn more calories, you may end up eating beyond your caloric requirement.
Research hasn’t found any direct link between the development of gout and whey protein consumption. However, it has been noticed that including whey protein in your diet when you happen to suffer from gout, worsens your condition further.
If you have a family history of gout, it’s best to consult a physician before starting on whey protein.
If you are a patient with heart disease, ensure that you always consume whey protein as per the specified dosage.
Exceeding this dosage could cause you heart arrhythmia, cardiac arrest and perhaps, even the complete loss of cardiac functions.
Sustained excessive whey protein intake could cause a mineral imbalance in your bones.
The imbalance could then deplete bone density, leading to osteoporosis.
Whey protein consumption increases the pH level in our blood. Our kidney finds it difficult to metabolize this excess protein.
As a result, our blood becomes more acidic.
A high-protein, low-carb diet uses energy from the burning protein in the lack of adequate body fat.
Ketosis is the condition when an abnormal amount of ketone bodies accumulate in the blood. Ketosis puts enormous pressure on the liver to function and can cause liver damage over time.
Individuals who are lactose intolerant may have difficulty breathing and develop allergic reactions such as wheezing, lip/mouth/throat swelling, and so on.
If you notice any of these symptoms forming, consult a physician at once.
When you consume natural protein, you may be doing so, along with other nutrients, but it is still more wholesome than protein supplements.
Whey protein powder is processed and disturbs the natural nutritional intake of our body.
Now, that we’re done discussing whey protein side-effects, let’s learn about the forms that they are available in.
The difference in the forms of whey protein stems from their manner of processing. They also determine their nutrition facts.
Hydrolysate or hydrolyzed whey is whey that has been pre-digested. It gets absorbed faster than the other forms. Hydrolyzed whey is responsible for a 28-43% spike in insulin levels than whey in the isolate form.
Isolate whey protein contains 90% protein and sometimes, even higher. It contains less fat and lactose as well as lesser beneficial nutrients than is found in whey protein concentrate.
Whey protein in concentrate form contains around 70-80% protein. It also contains lactose and fat. Overall, it is the most delicious of all the whey protein variants.
If you do intend to start consuming whey protein, choose a concentrate as, not only is it cheaper – it also retains the most amount of naturally occurring nutrients in whey.
However, if you are strict about the carbs and fats you consume, the isolate or hydrolysate form may be a better option for you. Most of the research done on it has been carried out in an isolated form.
The hydrolysate form offers the best digestibility, making it the whey protein source for the medically ill and infantile. They also have the least allergenic potential, making them safe for use.
Whey protein powders and supplements are a healthy and effective way in which you can contribute more protein content to your regular diet. It is a stellar source of protein which is seamlessly absorbed by our body.
Whey protein works best for weight trainers, athletes, people who lack enough natural proteins in their diet and others, who could do with more muscle mass and strength, and less body fat.
Protein is the most effective nutrient there is, to encourage muscle gain and fat loss. It is among the best sources of protein there is. So naturally, anybody looking to add more of the nutrient to their diet would do well, to buy themselves some whey protein powder. The concentrate is the most popular form of whey protein because of its agreeable taste. You could mix it in your food, or beverage or have it as it is.
If your goal is to lose weight, starting a weight training regime alongside whey protein consumption is the route you should take. It will help boost your metabolism, preserve lean muscle mass and aid you in losing those extra pounds.
