What is Whey Protein?
Whey is one of the two major proteins found in milk, the other is casein. Whey is the liquid portion of milk that separates during the production of cheese. Once separated this liquid undergoes production to become the whey protein powder we see in stores.
Whey and Weight Loss
One benefit of adding whey protein to your diet, is that is can play a role in aiding in weight loss. Some of the nutrients found within whey protein aid in protein synthesis inside the body which burns quite a few calories. Another way whey protein can help with weight loss, is that consuming it has been shown to satiate appetite. This means that after consumption, you will stay fuller, longer. With this, whey protein can also be used as a meal replacement when combined into something, such as a shake.
Whey and Muscle Gain
Whey protein is very popular amongst people looking to gain muscle mass. One of the biggest reasons people turn to whey protein for this, is that whey provides a faster absorption rate compared to other forms of protein. Whey protein also provides protein, amino acids, and insulin for increased muscle growth. Leucine, one of the amino acids found in whey protein, is known to stimulate muscle synthesis within the body.
Whey Protein and Lactose
According to the Genetics Home Reference, about 65% of people have trouble digesting lactose. While whey protein does contain only small amounts of lactose, for some, this still may be enough to upset your digestive system. However, a recent study published in Women’s Health Magazine, reports that lactose may not be the cause of digestive upset many people experience from dairy products, but rather a protein found in the cow where the dairy product has come from. Cows can produce milk with two different kinds of protein, A1 and A2.
In the distant past, all cows produced milk with the A2 protein, but due to production changes and large-scale farming, the A2 protein mutated to A1. In the study conducted with patients suffering from what was believe to be lactose intolerance, those who consumed the A1 milk had greater gastrointestinal inflammation than those who consumed A2 milk.
Which Whey is Right for You?
Depending on processing, there are three major kinds of whey protein available for purchase. The first is whey protein concentrate which is about 70 – 80%, contains some lactose, and has been known to be the best tasting whey. The second kind is whey protein isolate which contains a higher amount of protein, typically 90& or higher as well as less lactose and fat than whey protein concentrate. However, whey protein isolate is missing many beneficial nutrients that can be found in whey protein concentrate. This final kind of whey protein is whey protein hydrolysate which is pre-digested so that it is absorbed faster by the body.
If you have trouble digesting lactose, or possibly the A1 protein found in most dairy products, consider using a whey protein such as SFH Whey Protein Powder that uses only A2 cows for production.
