soy vs whey?

What's the difference?  Which is better?

Soy is from Soybeans and Whey is from eggs. Whey is better according to the stats.

Whey is from milk.

Of course you are right. Brain fart this morning...

No problem...I get brain farts on a regular occasion.

I prefer whey because I avoid anything that can cause an increase in estrogen because of being high risk for breast cancer. Soy contains phytoestrogens. How much of a difference does it really make? No idea. But I do every little thing that I think can make a difference, because it's all I can do.

Whey is from dairy- whey protein isolate is the type usually recommended for the best utilization for people that need a high quality protein source.

Choose whey but keep an eye on the stats.  Some protein drinks have too many carbs or calories.  Compare and shop carefully.
