The World of Whey

Whey protein powdersare some of the most common fitness supplements on the market today. However there are many differences to consider when it comes to choosing which whey protein supplement is best for you. First, let’s take a look at why so many people supplement their diet with whey protein.

Whey Benefits

Studies have indicated that whey protein can provide the following benefits:

• Improved athletic performance
• Enhanced Immune system function
• Decreased blood pressure
• Better function of the digestive system
• Reduced risk of gastric mucosal injury

Possibly one of the most popular supplements for athletes, whey protein is believed to accelerate muscle development and assist in muscular repair.

What is Whey

Whey protein is basically an assortment of globular proteins that are isolated from milk plasma. Milk plasma, or “whey,” is essentially a liquid by-product produced during the manufacturing of cheese. The biological value (BV) of whey protein is exceptionally high and, for this reason, very desirable among bodybuilders and athletes alike. Basically, a biological value indicates how much protein is contained within 100 consumable grams of a given substance. The only foods with a higher BV than whey protein are eggs which contain high levels of fats. For this reason many athletes opt for whey protein or a combination of both.

Types of Whey

Whey protein is usually sold in three popular forms which are concentrate, hydrolysate and isolate. Concentrate proteins contain low levels of fat and cholesterol, but on average contain greater levels of bioactive compounds and carbohydrates such lactose. Hydrolysate proteins are partially hydrolyzed and predigested making them more easily absorbed. However, due to these processes they’re typically more expensive too. There have also been reports that hydrolysates have a very distinct taste as well. Isolate proteins contain even less fat than hydrolysate or concentrate proteins, but also contain fewer bioactive compounds as well. Isolate proteins are also known to have a faint milky taste.
