What's So Great About Whey?

Many people are recognizing that their diet is very carbohydrate focused and lacking in protein sources.

It can be difficult to get more protein into your diet, but a quick and easy was is through whey protein.

According to the Whey Protein Institute, whey protein is a pure, natural high quality protein from cow's milk.

It is a very rich source of the essential amino acids needed by the body. Amino acids are the body's building blocks for healthy muscles, skin, nails and other body tissue.

You may be surprised to learn that not all proteins are created equally. Protein foods vary in a number of ways, like the number and quality of essential amino acids and their digestion and absorption rates. Proteins vary in fat content, taste and purity.

Whey protein is considered a superior protein because it is a high quality complete protein with rich amounts of all the essential amino acids. Whey protein isolate is the purest form of whey protein, and that purity makes it easily and efficiently absorbed by the body.

Whey protein is a wise choice if you are looking to change your diet to help improve or maintain your health. Whey protein offers excellent health benefits.

Heart Health – Heart disease is a leading cause of death for both men and women. A nutritious diet and regular exercise are essential for keeping your heart healthy over the long term. Excellent research has demonstrated that whey protein can help against high blood pressure, a leading cause of heart disease and stroke.

In addition, high cholesterol, another factor in heart health, is affected by whey protein. Researchers postulate that certain bioactive components in whey protein may be responsible for cholesterol reduction. Research is ongoing in this area.

Diabetes – Adult onset diabetes or type two diabetes is reaching epidemic proportions in North America, due in large part to rising obesity rates. Ensuring a healthy diet is essential for people managing diabetes and those trying to prevent it.

Weight Loss / Management – Another benefit of whey protein is its' ability to help you improve your body composition. The amino acid leucine has been shown to improve body composition. Whey protein is rich in leucine and is a better source than milk protein, egg protein and soy protein.

In addition, whey protein contains bioactive components that stimulate the release of two appetite suppressing hormones. A study has proven that whey protein impacts satiety better than casein. So, a whey protein shake as a snack can help you control how much food you eat until your next meal.

Cancer – With cancer rates on the rise, and some estimates suggest that one in two people will get cancer, a lot of research is being conducted to determine what people can do to best protect themselves. Whey protein has been demonstrated through animal and in vitro studies to inhibit the growth of several types of cancer tumors.

One study in rats found that those fed whey protein developed 50 percent fewer tumors than the rats feed casein (the primary protein in milk). The rats fed whey protein also developed fewer tumors than the group fed soy protein. In addition, the tumors took longer to develop.

Bone Loss – As we age, bone loss is a serious concern. Good nutrition and weight bearing exercises are so essential for protecting your bone density. A Boston study determined that people who consume low levels of protein had a serious loss of bone density, four years after the onset of the study, particularly in the spine and hip areas4. They concluded that a nutritious diet including whey protein could help keep bones healthy and strong.

Next time you are at your local health store, pick up a container of whey protein powder. It comes in tons of great flavours and it is so easy to whip up a delicious shake using milk, water or juice. Experience the wonderful health benefits of whey protein by consuming at least one to two servings per day!
