Whey protein has been recognized for its importance in health for hundreds of years. Since ancient times, the people of Florence, Italy have said, "If everyone were raised on whey, doctors would be bankrupt." Today, a great deal of research has gone into the importance of whey protein, with many astounding results.

For example, studies into whey protein and cancer have demonstrated that whey protein reduces the development of cancer in laboratory rats. More recently, whey protein has been shown to send the cancer tumors of human patients into regression when supplied regularly. Further studies have indicated that whey protein actually makes cancer cells more susceptible to forms of cancer treatment, making them easier to destroy.

Whey protein has also shown to inhibit oxidized low-density lipoprotein cholesterol. Researches believe low-density lipoprotein cholesterol ultimately leads to the formation of plaque and lesions in the arteries. Therefore, research indicates that whey protein helps prevent the formation of what is commonly referred to as "bad" cholesterol.

Furthermore, whey protein increases the body's levels of glutathione, which is a water-soluble antioxidant. This antioxidant protects the body from many harmful compounds, such as carcinogens, heavy metals, and other toxins. People with serious immune deficiencies, such as those associated with Alzheimer's disease, AIDS, and Parkinson's disease, have low levels of glutathione.

In addition to helping in the reduction of health complications, whey protein also assists in bone growth and strength. With all of its proven health benefits, whey protein should be included in everyone's diet.
