Protein Powder - Soy vs. Whey ?

I tend to stay away from soy products because of the estrogen, so I use Jay Robb's chocolate protein powder. Pretty natural, very low in sugar, not as much weird heavy metals like most protein powders, and it tastes the best, in my opinion.

He has an egg white protein as well, but the whey has more grams of protein in it.

No difference between the two other than Soy coming from a plant and Whey coming from a cow. Keep in mind that Soy is just starting to penetrate the mainstream market which makes the dairy industry feel threaten to the point that they do everything in their power to make Soy look bad by making such claims that Soy causes cancer. The next time you're at the grocery store, compare dairy milk to soy milk and you'll see why the dairy industry feels the need to fund propaganda against Soy milk. Soy milk has a shelf life of 3 months and is generally around 1/3 the calories as milk.

Whey is generally believed to be the faster absorbing and less expensive option. It is great for post workout as it gets into the muscles quickly. There is a lot of variety, ON has a natural line, and many have a full compliment of amino acids to help with recovery.

As soon as someone starts touting conspiracy theories as a reason to use/not use a product I tune out.

whey has a great amino acid profile.

Post-workout or first meal in the morning, go with a high-quality whey that has an extensive amino acid profile available. Isofusion is the best whey supplement that I have found for the price, of course Platinum Whey by Optimum and Isopure are pricier options. Are you on a low-carb diet? The reason I ask is because you really want to use a fast-acting simple carb with your whey supp if you are using it post-workout because of the transport involved. This really maximizes your muscle gain/maintenance and ensures that you arent wasting time with resistance training...assuming you are looking to increase your lean body mass, of course.. 2cents

I think whey is the most inexpensive option. Plus, soy and I don't get along. But there are a lot of options when it comes to protein sources in protein powder. I like to mix it up. One day I'll drink a whey based protein powder, the next I'll use a vegetarian formula (like Vega One - which gets protein from pea, hemp and brown rice). I just tried the "Garden of Life" brand RAW Vegan protein powder and it was sooo chalky. I can only drink it if I blend it in a blender with a bunch of other stuff.
Experiment and see what works best for you.

I use soy, whey makes my stomach upset. Soy is also a complete protein, most people that use soy do so because of dairy or egg allergies or they are vegetarian or vegan. Personally I love it and there is no nasty taste like you get with whey. I use GNC soy isolate, gmo-free. And pay no attention to those people scared of soy because of "estrogen", that's just a big lie made up by the dairy and meat industry to scare people off...of course...those same industries won't tell you that most meat and dairy has real animal hormones in it, including estrogen..soy is a plant...it's hormones are not related to humans. But thats fine if people want to be scared of soy. More for everyone else. it's also cheaper than whey.

I'd go for whey. While its anecdotal, my friend used to drink miso soup everyday and stopped menstruating for about 7 months due to the way the excess soy interacted with her hormones (specifically estrogen) <---her doctor explained this to her. She cut out the miso soup, and everything went back to normal.

And to the person who said it's a lie that soy intake affects hormones....EVERYTHING we eat affects our hormones.

So yeah, I'd just go for whey. Or lots of egg whites and fish (what I choose). Or whatever works best for you.

Then I guess whey affects hormones too, go figure. To each their own. I haven't grown an extra boob or anything from soy so it's okay for me.

I can't tell if you were trying to be snarky in your response, but this MFP, so such is life. But anyways, the way different foods interact with our bodies is pretty interesting. Whey definitely affects hormones. Some foods affect hormones positively and some negatively, depending upon individual genetics. I think it's cool that our bodies are so complex.

It was a joke but I found it relevant since you used a anecdote from someone who ate soy before so I thought I'd throw in my experience. If that changes I'll be sure to make a big post about it. Of course those with food allergies, ect should stay away from foods they know aggravate them. The thing is, just watch that goes in your body, like the outcome, stick with it, don't like it, don't do it.
