Whey Protein vs Casein

I get a lot of questions about whey protein versus Casein.  I also get questions about why I suggest getting off of diary, but then let my clients have whey protein powder.

Well, the short answer is this.  If any of my clients have diary intolerance or lactose intolerance or allergies,  they should not ingest whey protein.  In addition, many people feel bloated,  are overweight and consume too much diary.   But here’s the long answer.

Because whey protein contains only small amounts of lactose, it generally isn’t enough to trigger the side effects commonly associated with dairy intolerance.  Whey is a byproduct of the cheese making process; it’s the liquid portion that’s left behind when the solid curds are removed.  One of the two proteins found in whole milk, whey is frequently sold in powder form as a dietary supplement.  Because whey protein contains only about 5 to 6 percent lactose, it can be eaten by most people who have lactose intolerance simply because there isn’t enough lactose to trigger symptoms. However, if you are lactose intolerant, it can still cause problems. The Whey Protein Institute recommends that you use whey protein isolate products instead of concentrates. Whey isolate contains less than a tenth of a gram of lactose per tablespoon, whereas concentrate products can vary widely in the amount of lactose that they contain.

Eighteen percent of the protein found in milk comes from whey. Whey is extracted when milk is formed into cheese. Contrary to casein protein, whey digests extremely quickly, sometimes in as little as 40 minutes.  Approximately 82 percent of milk protein is casein, according to the College of Agriculture and Life Sciences at Cornell University. Casein is a slow-digesting protein; it can take as long as seven full hours to fully digest.

So as you can see from the percentages, Whey is only 18% of the protein of Milk….. which is a very low.  Thus it does not have the impact on your hormones like other dairy products do, that are 100% diary.

When you consume diary, you have more of a chance to develop allergies and intolerance.   Dairy intolerance and milk allergies are not the same thing. Milk allergies are an adverse reaction to milk and products made with milk.  Some symptoms or reactions may include an itchy throat, facial swelling, vomiting and diarrhea in adults. Infants may experience colic and immune system problems. If you have milk allergies you should not eat whey protein or any other milk-based products without consulting your doctor first.

The main reason why I do not recommend that you consume diary is due to the hormones that are injected into the animals that end up in the diary product you consume.  It not only raises havoc with your own estrogen levels, but it will also impact your ability to burn body fat due to all the synthetic hormones, preservatives and chemicals that are in these products.  If you must consume diary, at least purchase organic.  But, just to be clear, even if it’s organic, the diary itself will change a women’s hormone panel and most likely cause weight gain and symptoms due to multiple physiological factors.
