"Protein isolate powder is not recommended, because as Sally Fallon writes, “We have already seen that both fats and carbohydrates can be devitalized by processing and refining. *The same can be said of proteins. *Isolated protein powders made from soy, whey, casein and egg whites are currently popular as basic ingredients in diet beverages and many so-called health food products. *These protein isolates are usually obtained by a high temperature process that over-denatures the proteins to such an extent that they become virtually useless while increasing nitrates and other carcinogens [cancer causing substances].
Diets in which unnatural isolated powdered proteins from soy, eggs or milk are fed to animals or humans cause a negative calcium balance that can lead to osteoporosis. *Critics of meat-eating have seized on these results to claim that meat causes bone loss. *But meat or milk – as opposed to protein powders – fed to human subjects do not cause calcium loss nor do they contribute to osteoporosis. *The healthy meat-eating groups studied by Weston Price did not show any evidence whatsoever of osteoporosis.’
If you believe undenatured whey protein isolate would be a good source of proteins, particularly to obtain the amino acid glutathione, think again if you are lactose intolerant or you have candida albicans/yeast overgrowth. *Candida sufferers cannot tolerate lactose in dairy products, except for butter because it contains the least of any dairy product. *The rule about lactose is: *“The higher the butterfat content the lower the lactose. Following is a table which shows that whey is high in lactose."
Protein Isolate Powder Not Recommended (Includes Whey)
The info comes from Weston A. Price Foundation and Sally Fallon, but this link came up with an explanation. Primal eating is about eating real, unprocessed foods. Protein powder is highly processed. Lots of people can lose weight eating processed foods, but that doesn't make it healthy. Not sure why Mark sells it, other than to make money.
