Whey Protein Facts
Here is a list of whey protein facts that is good to know in order to have a better understanding of whey protein.
Production Process - made from milk as a by-product during cheese production. The processing is done by a simple method of drying to get the powder form. The protein content (purity) can be increased by removing lipids (fat) and other non-protein materials. This is done through a process of filtering.
Main Forms of Whey Protein - typically it comes in 3 major forms:
- Concentrate - this form contains a low level of fat and cholesterol but also has a higher level of bioactive compounds as well as carbohydrates in the form of lactose.
Concentrate whey protein is 29% to 89% protein by weight. As for bioactive ingredients - the lower the bioactive compounds the beter. In other words, any kind of bioactivity produces some effect (as a result of the activity) and said effect can be adverse sometimes.
Think of a car engine which burns fuel to create energy. The energy is the positive effect while the exhaust fumes, which were created as a by-product, are toxic. Same thing applies to bioactive ingredients in any food that we consume - only on a smaller scale.
- Isolates - they are processed to remove fat and lactose and are lower in bioactive compounds as well. They are 90% protein by weight.
- Hydrolysates - this is the top of the line but also highest in cost because these types of whey protein are predigested which means our body absorbs them more easily. Moreover, highly-hydrolyzed whey is less allergenic than other forms.
Health Effects - no known side effects. Whey protein has been around for a couple of decades now and has proven to be safe.
This is one of the well known whey protein facts that has been validated by growing sales year on year. Furthermore, whey protein helps stimulate natural protein synthesis within our body which speeds recovery and optimal adaptation to stress (as in muscle stress when weightlifting).
Other studies have also suggested that large amounts of whey protein can increase celullar glutathione levels. Glutathione is an anti-oxidant that defends the body against free radicals and toxins atacking our body.
Other Ingredients - whey protein has a variety of other ingredients such as glutamine and amino acids. Glutamine helps prevent catabolism.
In other words, it helps your body feed itself from the ingested protein you take in through whey protein shakes and not by breaking down hard-earned muscle tissue. Amino acids are basic building blocks of protein and also help our body with a variety of metabolism roles.
Buying Whey Protein - things to consider! When buying protein you should be mainly concerned with the protein to carbohydrate to fat ratio.
You want the fat content to be as low as possible and the protein content as high as possible while the carb content should be relatively low as well.
Top whey protein brands will have anywhere from 24 to 30 grams of protein (per scoop/serving - it's always measured by scoops which come with the protein inside the container); low carbs - as close to 1 (gr) as possible; low fat - as close to zero as possible.
The basic difference between weight gainers and regular protein is that weight gainers have much higher carbohydrate contents (this is why they help you put on weight). The photo above shows a regular (non-weight gainer) whey protein label of one of the top whey protein brands. Take a look at the protein, carbohydrate and fat content.
We hope that these whey protein facts help you in gaining a better understanding of whey protein!
