Well it said when lowering total protein intake from high protein to low protein.Originally Posted by skunkman
You base your entire argument on that ONE study? One that isnt even conducted on humans in relation to a normal diet?
Take from it what you want. As others have mentioned, we don't NEED a slow digesting protein to stave catabolism and it has the POTENTIAL to grow cancerous cells. By all means continue to use it. I personally will be buying free range meat instead of casein.
True. But many things have the potential to cause cancer. Burnt toast, processed ham etc. I think your blowing it out of proportion. I dont mind (obviously) if you choose not to use casein, each to their own. But there are far more cases for Casein and Whey than against
Next, the natural diet of mice is considerable different than that of humans. The proportion of starch to fat to protein consumed by a mice is much higher than those consumed by humans. The typical lab rat is a herbavour, not omnivours such as humans. We see the same thing when feeding mice a high fat/low CHO diet, they quickly develop symptoms of metabolic syndrome. However, when fed a high fat low CHO diet to humans, symptoms of MX are often improved upon.
Do I think casein should be used as a dedicated, slow-digesting protein supplement? Hell no. Net anabolism/catabolism will determine body composition, not to mention that the bioavailability of casein is potentially lower than other protein products due to the wasteful agglutination known as paracasein that can inhibit digestion of the protein prior to entry in the colon. However, I am not going to avoid casein due to carcinogenic potential. If you're worried about cancers of the GI tract, curcumin + bioperine may be up your alley.
