Dangerous Proteins — Which Whey?

Fitness Fanatics are Passionate About Protein

“Whey protein is the best protein.” Whey protein is the worst protein.” Which is it? Is whey protein good, or not good. There’s conflicting information out there. I’ve heard both, so to clear up the confusion, I researched it.

This is not intended to be the answer, because I think there’s often not just one answer, one solution and one way that’s right for every body. That said, there is good research to indicate what might be better for most people.


Verdict: Stay Away from Whey Protein Isolates

Here’s some of the best info from a reliable source, Dr. Joseph Mercola who is a highly trained traditional allopathic physician with a natural, holistic and sports science training as well.

Whey protein isolates have dangerous Forms of Protein

Guidelines for Finding a High-Quality Whey

To ensure you’re getting a high-quality product, make sure the whey you’re buying fulfills the following requirements:

Organic (hormone-free) Grass-fed Made from unpasteurized (raw) milk
Cold processed, since heat destroys whey’s fragile molecular structure Minimally processed Rich, creamy, full flavor
Water soluble Sweetened naturally, not artificially, and without sugar Highly digestible—look for medium chain fatty acids (MCTs), not long chain fatty acids


Whey Protein to Improve Muscle Building

High-protein, low-carbohydrate diets have been repeatedly shown to be the most effective both for muscle building and weight loss.

Amino acids and protein are the building blocks of your muscles, but certain amino acids, such as leucine, can also signal genes in your muscle to grow and build protein, and they do that even during times of food deprivation as long as these amino acids are circulating through your blood stream.

Hence, there are two primary factors involved in effective fitness nutrition (regardless of your age):

  1. A high-protein, low-carbohydrate diet
  2. A diet high in certain amino acids, the most notable of which is leucine

Whey protein is the perfect “fitness food” as it contains not only high quality protein, but also extremely high amounts of leucine.

Here’s the big problem with whey protein powders: many of them not only won’t do what they claim, but they can even cause health issues and health decline. In searching on Amazon to find the best powders there to link here for you, so far 10 out of 10 of the top protein powders searched, contain whey protein isolates. That is NOT what you want.

All whey protein isolates are devoid of nutritional co-factors including alkalizing minerals, naturally occurring vitamins, and lipids, which are lost in the processing… This renders them deficient and overly acidifying. Unlike whole protein food concentrates which does not acidify your body due to its alkalinizing minerals, whey protein isolate are over acidifying.

Whey isolate can be a serious liability.”
