I got this article from PTonthenet. It may be ridiculous to some but it may give you something to think about. I will post the references at the bottom after I post the article and I would like to know what you think about this.

Whey Products Part 1 – Supplement or Detriment?
By Paul Chek

Trade journals and exercise and bodybuilding magazines are bulging at the seams with ads for whey protein powders. Many of them tout amazing improvements in everything from strength, endurance, muscle size, energy levels and even improved immune system function. Are these whey protein powders all they are cracked up to be, or are they more like one of those movies that is advertised heavily, hyped up for months and, when you finally see it, you find the best of the movie was the ad itself? Well, as I will show you, it all depends on which way you look at it. To be capable of making sound choices in the purchase and use of any whey product including protein powders, it requires some understanding of:

* The source of the product
* How the product was processed
* Why it is being used
* How best to use it

Once these issues are addressed, the exercise and/or healthcare professional will be in position to optimally reap the benefits of whey products.

The Historical Relationship Between Man, Milk and Whey

The two great evolutionary periods in the history of humanity — first biological and then cultural — are very unequally divided. The steps of biological evolution that separate us, Homo sapiens, from a small stone-using creature in central Africa, Australopithecus, took millions of years, while cultural history is crowded into the last 10,000 or 20,000. Evidence indicates that people in the High Sinai Peninsula at the northern end of the Red Sea used fences to aid in confining and breeding antelope for their milk as long as 30,000 years ago. While this may be so, it is likely that both civilization and regular consumption of animal milk only occurred when huntsmen turned into herdsmen. It was the Indo-Europeans of central Asia who were among the earliest consumers of animal milk. This region (the Near East and Balkan Peninsula) is also thought to be the origin of the agricultural revolution occurring in approximately 6000 BC.

When one considers that all plants and animals exhibit a will to live and don’t want to be eaten, it becomes evident that milk is the only substance purposefully designed and prepared by nature as food. In all cases and until very recently (in the last 10,000 years), both animals and human beings consumed milk as a whole food, not processed or fractionated in any way. Considered the fruit of all mothers, milk is produced at the nutritional expense of the mother’s own body if she is not adequately nourished with the sole purpose of supporting new life. This point will be considered carefully in regard to whey products later in this debate. Loaded with all the needed micronutrients and antibodies to nourish and protect the growing infant, Mother Nature creates an individual recipe for each species in its own mother’s milk - a high fat, protein rich whole food.

With the innate knowledge that the unadulterated milk of a mother provides an essential foodstuff that is supportive of life, people have pursued alternative uses for it. Through trial and error, milk derivatives such as butter, cream, ice cream, yogurt, kefyr, buttermilk and many types of cheese have been made primarily from sheep, goats and cows to supplement the human diet. Most recently whey, a byproduct of cheese making, has resulted in the production of whey protein powders and bars.

Many tribes and societies in various regions throughout the world have maintained very high levels of health with the addition of natural, raw milk products in their diet. A particularly useful source is butter, which offers a wealth of fat soluble vitamins and other useful nutrition when derived from a quality organic source. While most people don’t realize it, whey - until very recently - was considered a waste product by the dairy industry, and dairy farmers usually fed it to their pigs. It was only after having dumped untold millions of gallons of whey into rivers and even on roads that the cheese industry investigated making whey protein from the waste product. While there are numerous research studies touting the many benefits of whey protein today, one must be very careful when reading such studies and claims. In most instances, the whey used in the studies is of far better quality than the whey the manufacturer actually produces and sells under the guise of the study. In fact, the only way to determine the quality of a whey protein product is to qualify the source, and you simply can’t make health giving, high quality whey products from sick cows!
